PBEM Tournament[Subject Thread] [Add Response]
M. Howe wrote on Fri, Aug 16, 2002 12:15 AM UTC:
There certainly are a lot of worthy games to consider, and this fabulous
website makes it both harder and easier to decide.  Harder because so many
interesting games can be found here.  Easier because you can read their
rules at a click, and in some cases read what others have thought.  I
looked at the games suggested by others, and a few games I am partial to
myself, and came up with this list:

Among newer variants:
  Rococo certainly looks very interesting -- perhaps a better Ultima.
  Separate Realms is new and promising enough to warrant some play.
  Take Over has an interesting mechanic that I'd like to see explored.
  Crazy 38s is so original and innovative that it begs to be played.
  Caissa also has a unique and interesting mechanic and I've always
wondered how well it plays.
  Flip Shogi looks interesting.
  Cannon Shogi looks likes an interesting shogi variant with added power
on the board.

Among large variants:
  Centennial Chess looks fascinating, and for the adventurous, perhaps
even Millenial Chess by the same inventor.
  Some form of Grand Chess seems like a good idea -- I think perhaps
Grander Chess might even be the best choice.
  Reniassance Chess also looks to be a worthy entry in the large variant
category.

Among hexagonal games:
  Hexagonal Chess by Shafran has always struck me as perhaps better than
Glinski's game -- it would be intersting to find out.
  Hex Shogi by Duniho -- perhaps a small board variant is called for, but
that all look intriguing to me

Among established variants:
  Extinction Chess has always struck me as a great, simple idea.
  Chessgi is an acknowledge classic, a great game.
  Rifle Chess has always intrigued me.

And I guess I better stop there, since I've already listed more than 10. I
could easily go on.  I'll resist the temptation to list my only TCVP entry
(Biform Chess) since I've recently had second thoughts about the starting
array.  And it's too bad that this is all happening just a few weeks
before my own new games come out, but I suspect that interest in them will
be a little limited anyway, since they're both big-board variants (10x10
and 11x11) and one of them is very unusual and Ultima-like.

What kind of time frame has been proposed for these games?  A move per
day?  Will there be a time limit?  I'd love to play, but some days I'm so
swamped I can't afford to think about chess.

I noticed Ben's comment on the 84-space contest.  Aside from the fact that
we won't want many games that size in any case, I don't think that any
game being voted upon in 84-spaces should be eligible for this event. 
Even its presence in a poll to pick the games could affect the contest
voting.

We may miss a good game that way, but if this flies there's always next
year.

I just checked Peter's linked recommendations, and I shake my head.  There
is so much good stuff there, and elsewhere on CVP, that you cannot track
it all.  :)

I wonder what Ralph Betza, in particular, might suggest?  He's been at
this a while...

Glenn Overby II wrote on Thu, Aug 15, 2002 02:06 PM UTC:
I did a list of eight, trimmed from a first list of nearly 40, to show how
a set of games might feature a wide range of styles and options.  In
alphabetical order:

Chigorin Chess (Betza)...non-matching forces
Extinction Chess (Schmittberger)...new objective
Magician Chess (Whittle)...small board, new piece, board alteration
Not-particularly-new Chess (Aronson)...add-a-few-squares-and-new-piece(s)
genre
Sudden Death Chess (Chatham)...simple rule change with radical
implications
Take Over Chess (Quintanilla)...small board, different captures, new
piece
Triplets (Sobey)...multi-moves, alternate objective
ximeracak. (Overby)...sweeping piece changes to standard set

I share David's nervousness about larger games, although Modern Chess,
21st Century Chess, and Chess on a Longer Board With a Few Pieces Added
are on my long list.  So are Crazy 38s and Separate Realms (from other
people's lists).

I would like to feature some prizewinners from our contests, and while the
tournament should feature lesser-played designs it might not hurt to have
a better-known game or two in the mix.  Losing Chess is another I'd
consider for that role.

I'd have to search around for games.  off the top of my head, i'd also
definitely recommend rococo and ruddigore by aronson.  i also recommend
schizophrenic chess, altho i don't know if we want to overlap this with
the 84 square contest.  i might also suggest my own game crazy38s.  what
else... captain spalding chess by betza.  if we want a 3D game, i'd
suggest millenium 3D by a'gostino or exchequer by hewson, since they can
both be played in about the same amount of time it takes to play a
standard chess game.  i am also a big fan of rennaissance chess by eric
greenwood.  i also like the the commercial game quantum II, III and IV.  i
also like looneybird, even tho freeling is no longer big on it.

sorry this message wasn't as organized as aronson's, nor does it link to

Glenn Overby II wrote on Thu, Aug 15, 2002 12:07 AM UTC:
We've been talking among the editors about trying to run a multivariant
PBEM tournament in 2003.  The goal is to get some of the better new or
obscure variants more play and exposure (although there will be room for
more usual games as well).  Each player would play a total of six games,
in at least five different variants from a list of seven or eight.

The crucial question is what variants to feature.  What ought to be played
more?  Which games should get a chance?  There are so many good ideas here
that no one person can begin to evaluate them all.

We ask all of our readers to consider adding a comment here.  Suggest one,
or two, or five, or ten games to be considered.  We'll eventually use your
suggestions and our editorial deliberation to put together a list of 25-40
for a formal poll.  That poll will determine the games to be used, if
there's enough interest.  We hope there will be.

Please, let your voices be heard, and help us build a cool new event.

Has anyone archived the chess variant 'Schach des Macchiavelli'
published in the beginning of the 80ies in the german alternative
newspaper 'die tageszeitung' (taz)?

I remember the following facts: It was a 4 player variant on
a non-checkered square board. The central field was special:
If your royal piece was placed there, you had additional moves
after every other player's moves. Captured pieces are left as
corpses on the board. They could be moved only by a special unit,
the nekromobil, which was unable to capture.

Any hints are welcome.

I, for one, intend to play test the various games before I 'pass

An Odd Piece[Subject Thread] [Add Response]
Mike Nelson wrote on Sat, Aug 3, 2002 03:24 PM UTC:
Peter, if you are willing to do it I would appreciate it very much.

Jorg, neat mate! Possibly Separate Realms Chess is playable with an
orthodox king, though I still prefer the weaker king for the game. I
wonder if the starting position for the mate can be forced though--I think
a defensive stategy for this game will be to keep the king away from the
edges to maximize its mobility.

Peter Aronson wrote on Sat, Aug 3, 2002 12:07 AM UTC:
That's a neat mate, Jörg! <p> Does that mean Separate Realms Chess could go back to using a standard King? I think I like the current King, even if it isn't strictly necessary, since it carries the theme of the game to completion -- every piece restricted to some subset of the board when not capturing.

Peter Aronson wrote on Fri, Aug 2, 2002 03:56 PM UTC:
So, Mike, who's going to do the page? <pre>&lt;g&gt;</pre>

Mike Nelson wrote on Fri, Aug 2, 2002 03:15 PM UTC:
With the weak King (FcW) and stalemate as a win, the proposed game isn't a
bit drawish. K vs K on the same color is a forced win for whichever side
can get the opposition. (This is a simple calculation: if the coordinate
differences between the Kings are odd, for example a1 vs d6, the player on
move wins; if the differences are even, the player not on move wins.)

Similarly, if the Kings are on the same color K and any piece vs K is a
forced win unless the bare K can capture the piece--the stonger side can
use the mobility of the piece to avoid zugzwang.

Anonymous wrote on Fri, Aug 2, 2002 07:13 AM UTC:
It is not sufficient for the king to be on a secure
file or rank, to force a draw against king and oddling
it has to be in the secure corner.

Here is how to mate the black king with king and 
oddling:

White: Og7,Kh6  Black: Kf8

First, White brings its king to h8, than it pushes 
its king forward using zugzwang until it reaches d8.

White forces the Black king to a8. Now the finale:

Kc7!  Ka7
Og5   Ka6
Oe5   Ka7
Oa5++

Mike Nelson wrote on Thu, Aug 1, 2002 07:29 PM UTC:
R on seventh rank and bare enemy K on eight rank IS stalemate! How did I
overlook that?

Mike Nelson wrote on Thu, Aug 1, 2002 07:13 PM UTC:
Peter,

I think you're right--bare king rule should not apply.  There will be some
interesting endgames with stalemate as a win. For example, K and R vs K
can be a win if the pieces are in the right realms, such as R holds enemy
K on the last rank as friendly K moves to stalemate. 

I rather like the sound of Separate Realms Chess.

Mike Nelson wrote on Thu, Aug 1, 2002 05:42 PM UTC:
Peter, thank you for the ZRF.  I haven't though of a name--fell free to
give it any name that appeals to you--the ZRF is much harder work than
thinking of the game, plus the whole idea followed logically from your new
piece.

It think both the stalemate as win and bare king rules as in Shatranj
would be good idea for this game, in fact for any game with weak pieces.
(Though I've used these rules in games with strong pieces as well.)

Mike Nelson wrote on Thu, Aug 1, 2002 05:25 PM UTC:
No, the odd piece does not have the 'can-mate' property.  If the odd piece
(mDDcR) is on the seventh rank holding the bare enemy K on the eighth
while the friendly K moves in, the odd piece can't move to the eighth rank
to mate! If the odd piece is on the sixth rank, it can't hold the enemy K
on the eighth--the whole seventh rank is safe.

Two of the odd pieces, one on a even-numbered rank (or file) and one on an
odd-numbered rank (or file) should mate easily.

Peter Aronson wrote on Thu, Aug 1, 2002 05:20 PM UTC:
Jörg, I'm not sure about the can-mate part. It seems to me that in a lot of situations the piece would result in stalemate, not mate. <p><hr><p> Mike, I threw together a crude ZRF of your game last night -- it seems to play OK. But I was wondering if stalemate ought to be a loss instead of a draw, as the nature of the game makes it more likely, as does, unfortunately, changing the King from WF to FcW. <p> By the way, do you have a name for it?

Anonymous wrote on Thu, Aug 1, 2002 07:27 AM UTC:
This odd piece oddly is almost a rook worth in the endgame.
It still has the can-mate property, except for the rare case
that the bared king is in the secure corner (If the odd piece
is on a1, the secure corner is a8). In the most cases it
can block the secure corner and the bared king is driven by zugzwang
towards a mate. The secure spots left by the odd piece are all 
single fields without secure neighbours -- thus a bare king must leave
them.

Peter Aronson wrote on Wed, Jul 31, 2002 10:27 PM UTC:
I think the weakened King might to the trick, though I would express the
funny notation as FcW.  The resulting game ought certainly to be
different!

Mike Nelson wrote on Wed, Jul 31, 2002 10:08 PM UTC:
Perhaps this would make it less drawish:  The King moves as a Ferz and
captures as a King (mFcK) and cannot castle.  The former change means less
force is needed in the endgame, the latter enhances the chance of a middle
game victory.

Peter Aronson wrote on Wed, Jul 31, 2002 08:00 PM UTC:
I considered the Bishop equivalent, but decided it would likely be too weak. <p> Mike Nelson has proposed a game based on these sorts of pieces -- you can see it in the comments for Colorboundmost Chess. My suspicion is that there would not be enough power in the board in the endgame, making the game drawish.

Jared wrote on Wed, Jul 31, 2002 07:21 PM UTC:
Hmm... very interesting.  Did you consider the Bishop/Queen equivalents? 
Or even (gasp) the Nightrider equivalent (moves as a 2/4 rider or captures
as a 1/2 rider)?  The latter seems like an especially odd piece,
preferably for use on really big boards.  And how would a king like this
work?  Move as an Alf./Dab. and capture like a king, or capture like an
Alf/Dab/King?  And would a CV in which every piece is like this work well?

Mike Nelson wrote on Tue, Jul 30, 2002 09:55 PM UTC:
It seems like a most interesting piece indeed. Such a piece could be the
basis for a variant along the lines of Ralph Betza's Colorboundmost Chess.
I will post details as a comment to Colorboundmostr Chess.)

Peter Aronson wrote on Tue, Jul 30, 2002 05:32 PM UTC:
When I go to sleep at night, I often try to think about something interesting or pleasant while I drift off. Last night I found myself thinking about an odd Chess piece. <p> The piece moves without capturing like a Dabbabah-Rider (repeated leaps of two squares in the same orthogonal direction), but captures like a Rook. So, mDDcWW or mDDcR in Ralph's funny notation. <p> And I found myself wondering: how powerful is this piece, and what sort of game or problem would it be good for? I has a number of curious characteristics: except for capturing, it is doubly colorbound, being restricted to 1/4 of the board; and while it can switch by capturing, at any time it can only attack 1/2 of the board. <p> It seems to me that this piece is vaguely cannon-like, being more powerful in the opening and midgame than the endgame. It also seems to me that it might be a very charming part of a piece mix. Any thoughts?

I agree with jianying, I think.  Cross-referencing all the variants sounds
like a LOT of work but not much gain.  OTOH, it might be worthwhile to
fully cross-reference a subset like the _recognized_ variants, as that's
where a lot of the better pieces either originated or were popularized. 
(Sometimes that influenced how the game drew enough interest to become
'recognized'.)

currently in the piececlopedia, many of the pieces list all the games that

lists the chancellor from capablanca's chess, the marshall from
grandchess, the champion from carrera's chess, etc.  i think this is a
good idea to have as much as possible, but it also sounds to me like
having an automated system for this is not worth the effort.  i think
we'll have to settle for pointing out any additions to the list to the

Quite often we get requests for information about a game that (for instance) is played on a large board and there was a piece called a 'Royal'. Now searching all chessvariant.com pages for the word 'Royal' turns up too many hits. So cross referencing can be useful when looking for games where piece names are commonly used words in other contexts. <p>Not that I want to do all this work of course, but if there is enough demand for it, perhaps it would be worth it.

I'm with Joseph on this: too much work for the payoff.  Think about keeping
it up-to-date; whoever's job that was might have no life in a heavy
contribution week.  Also, listing all the pieces in a game is redundant to
the actual game description.

If it were done, it would be most useful to be identified by move, rather
than name of piece.  This would be a sysiphean labor.  You would have to
create indices based perhaps on funny notation.  The syntax of funny
notation is ambiguous, in that although it can describe movement
precisely, there is more than one way to describe the same movement in
many cases.

We could cross reference piececlopedia items with game items, or simply associate a list of piece names with each game.

Peter Aronson wrote on Tue, Jul 16, 2002 03:50 AM UTC:
An alternate approach to balancing Colorboundmost Chess would to follow the
path used in other double-move variants -- only have white make a single
move on their first move.  I would suggest having white make their first
move on white, so that each player would make the first move on their
King's color.

Once you have white making only a single starting move, it should no
longer be possible for black to mirror white, so race rules could be
applied.

gnohmon wrote on Sat, Jul 13, 2002 12:29 AM UTC:
Oops. I forgot while I was writing.

There's a specific reason not to use Parton's fair race rule with an
absolute doublemove game of Absolute Colorboundmost Chess. 

The reason is that symmetrical play gives Black a guaranteed draw!

gnohmon wrote on Fri, Jul 12, 2002 03:32 AM UTC:
In Absolutely Colorboundmost Chess, there must be as little interaction as
possible between pieces on squares of different colors.

As a consequence, there can be no Castling. A further consequence is that
you should really play it on two boards, lest the visual clutter become a
sort of interaction between the two colors.

The big surpsise is that it must be a doublemove game, one move on each
color. If you have only one move, and must decide between colors, that is a
form of interaction! (Yes, that interaction would make a better game; but
the absolute extreme colorboundmost chess has to be doublemove.)

Your Q is on the same color as the enemy K. This means that you start with
enough material superiority to mate the opponent -- but of course the
reverse is also true! I see this as a race game (pushing the boundaries of
race games!), and therefore immediately thought of Parton's 'Fair race
rule' from Racing Kings: if W gives mate, Black can draw by giving mate in
reply. (The question of who wins first is an interaction between the
colors, but it is unavoidable in a chess variant.)

However, since it's a doublemove game, an even better alternative is to
make it 'balanced'. W only gets to make one move first turn. 

To avoid interaction, the rules must specify on which color W must move on
the first turn!

Of course all the pieces and Pawns and Kings must be colorbound. (Also, a
game with weak interaction played as a singlemove game on a single board
would be more interesting; but the first step is to define the most
extremely absolute colorboundmost game possible!)

Am I correct in thinking that all these consequences follow inevitably from
the premise? Have I missed any? Is it interesting that this much of the
game can be specified without even thinking about how individual pieces
move?

i'm just wondering why in most multi-level chesses the boards alternate
their patterns (instead of a constant white in the bottom right), and this
is the only place i could think to ask.  Is it necessary for some reason? 
Would colorbound pieces be affected adversely if the boards weren't so
arranged ?

In the work of creating a chessvariant tournament called ChessWar I came up
with the idea of having a chatroom dedicated for chessvariants and more
spesific Zillion players (since the tournament will use Zillions to
play).

What I wonder now is if there are any interest in a chatroom from
chessvariant players and creators.
It would be a great place to meet other Zillion players since there aren't
really any such place at the moment. It would also be a good place to go if
you need players to test a game you have created.

The room will open during July but I'm very interested to hear thoughts
about the idea.

Now, I am certainly willing to accept that 0.5 of the value of the W is due to its forward move, but what I am less convinced of, I guess, is whether the W forward move by itself <strong>adds</strong> that much to of the value of the W to another piece that already has forward moves. It's at least an interesting question, I think. <p> If the Elephant is 0.75 N, and the Great Elephant is 1.5 N, then the White Elephants are about 0.5 N too strong (the exact amount depending on your opinion of the relative values of the N and B). If that's the case, maybe the Queen should be replaced by the War Elephant, Rook + Alfil Rider (RAA) -- this should be about the proper balance, since a Rook + Alfil would be a full 0.5 N weaker than a Queen, but since the Great Elephants are a tiny bit weaker than Rooks, maybe, and there's the Bishop differential, the extra strength of the AA over the A ought to just balance things. <p> <hr> Captain Spalding Chess!? -- Marxist!

While I am certainly willing to believe in the inaccuracy of playtesting as a means of determining the value of pieces (unless, of course, there are a great number of games played by strong players), still, I have some trouble thinking of the Great Elephant as a Rook-equivalent piece. <p> And I wonder. While almost 1/2 the value of the Wazir might come from its forward move, does that mean that that forward move necessarily adds 1/2 of the value of a Wazir to a piece, like the Ferz, which already has considerable forward movement? In the Great Elephant's case, the fWfD component adds two forward moves to a piece that has four already -- it seems to me that there ought to be some principle of diminishing returns here. There is also the strange issue of directional colorboundness; that the Elephants are colorbound when moving backwards but not when moving forwards.

gnohmon wrote on Thu, Jun 13, 2002 04:23 AM UTC:
Values are different in Shogi, where the drops and 6th-rank limited
promotion rules change all values. After I sought out and visited the Shogi
equivalent of the Nihon Ki-In (but decided not t play because of my limited
shogi experience -- the exercize of finding it on the map and actually
finding my way to a remote region of Tokyo was quite rewarding enough!), I
downloaded the supremely weak shogi master program from the home of the
underdogs, and played quite a bit; and my impression is that (1) having
more Pawns is good, but not specific number of Pawns is worth anything; (2)
fR == ffN; Gold == Silver == 2 of the previous; R == B == 2 of the previous
(although R versus B may often be decisive).

But in a 'normal' game, what's a Silver worth? My ancient researches seemed
to indicate that adding the forward move+capture of Wazir to something else
is worth nearly half as much as adding a whole Wazir; and that adding the
sideways moves is worth most of the remaining half-Wazir. For the Ferz, I
forget. It's written down somewhere but of course forwards is worth more
than half.

Thus, the basic estimate for the Silver General is roughly 3/4 of a Knight,
and the basic estimat for the Gold General is somewhat more than 3/4 of a
Knight.

If the simplest possible estimates of the values are taken, then your
Elephant may possibly be worth 3/4 N and your Great Elephant may possibly
be worth 1.5 N, which is roughly the value of a Rook.

According to the shock-troop theory, the combination of weak FfW which have
no jumping move and the strong fWfDWA which does have jumping, this
combination interferes with the harmonious development of the army; but
Philidor's shock-troop theory, although it contains some truth, is not the
final word. Morphy showed how one can cause great damage to the opponent by
developing the Rook-valued pieces, and his example must be kept in mind
when you are playing an army that includes HFD or Great Elephants as
R-valued pieces.

If the Great Elephant is Rookish in value, then it is logical that splicing
equine genes into the Greater Elephant must produce a Q-valued piece; using
this in the same army would be consistent but it would be overkill.

If my guesses about the elaphantine values are somewhat near correct, then
why does your playtesting seem to hint that the army is too weak?

In my experience, the unreliable values produced by my pseudoscientific
guesses are actually more reliable than playtesting. The most common
problem with playtesting is that if you don't know how to use a piece to
best advantage, it seems weaker than it really is. Learning to use every
possible piece is difficult and time-consuming.

<h4 align=center>What's the Value of a White Elephant?</h4> Here are some thoughts on a variant I've played around with, but never finished as I was uncertain about the balance. I thought they might be of minor general interest, so here they are. <P> Sometime back, after reading the Piececlopedia article on the <a href='../piececlopedia.dir/alfil.html'>Alfil</a>, I started thinking about the other sort of Elephant piece, the one that moves like a Ferz or one step forward (fWF), found in <A HREF='../oriental.dir/burmese.html'>Sittuyin</A> (Burmese Chess) as the Elephant, in <A HREF='../oriental.dir/thai.html'>Makruk</A> (Thai Chess) as the Thon, and in <A HREF='../shogi.html'>Shogi</A> (Japanese Chess) as the Silver General. <P> It's a simple piece, but what is it worth? A <A HREF='../piececlopedia.dir/ferz.html'>Ferz</A> is generally accepted to be worth about 1/2 a Knight (balancing colorboundness with a good forward move), but how much more does that single forward move add? I'm not as scientific about these sorts of things like Ralph Betza is, but it does add a lot. First, an Elephant is not colorbound like a Ferz is, and second, its forward moves are the same as a <A HREF='../piececlopedia.dir/man.html'>Commoner's</A>. In fact, you could look at an Elephant as 5/8's of a Commoner, which is generally considered a Knight-valued piece and about which Ralph Betza says: <BLOCKQUOTE> This is a very short-range and very flexible piece that is much weaker than a Knight in the opening, very strong in the middlegame if it can occupy the center, and almost always wins against a Knight or Bishop in the endgame. </BLOCKQUOTE> Of course, an Elephant is less flexible in the endgame where the opposing pieces very well might not be in front of it. But on the other hand, it has the three most useful moves of the Commoner for the opening. So we'll assume 5/8's of a Knight is about right; roughly two Pawns. <P> The next thought I had on the subject was what if I were to combine the Alfil and the Elephant? This produced a piece that moved one or two (jumping) diagonally or one square forward. Looking at this, I realized that if I added a two square jump forward (yielding fWFfDA) , I would repeat the shape of the Elephant's move (supposedly four legs and a trunk) on a slightly larger scale. Thus was born the 'Great Elephant'. <P> Now, what's the Great Elephant's value? It attacks 10 squares on an empty board, and it is neither colorbound nor colorchanging. The simplest calculation would be a Knight and a quarter -- 3.75 Pawns. The lack of colorchanging might kick it up to as much as 4 Pawns. <P> OK, the actual variant. Thinking about Ralph Betza's game of <A HREF='../d.betza/chessvar/ghost.html'>Black Ghost</A>, where black is given a piece worth less than a Pawn to balance white's first turn advantage, I decided to give white an Elephant-based army worth a tiny bit less than black's in order to balance white's first turn advantage. <h4 align=center>White Elephant Chess</h4> The rules for <B>White Elephant Chess</B> are as for <A HREF='../ichess.html'>FIDE Chess</A>, except where stated otherwise. <P> White's Bishops are replaced by Elephants (fWF), and Knight's by Great Elephant's (fWFfDA). Black's array is the usual FIDE array. <P> Pawns may promote to any non-Pawn, non-King piece that started the game on either side (Elephant, Knight, Bishop, Great Elephant, Rook or Queen). <hr> My suspicion (backed up unreliably by Zillions) is that white might be a tad <STRONG>too</STRONG> weak. I tried adding the Alfil's move to the white Queen's to produce the Queen Elephant, but that didn't seem right, either.

This is looking interesting. Have you tried it yet?

I don't see this as a problem with your game, mind you, but if it is correct players will have to be careful to keep in mind the new balance of power amongst the pieces. <p> I do wonder about the piece density -- 16 pieces on 64-squares do seem to rattle around a bit. I suppose you could double the back rows except for the Kings, although I'm not sure that would improve matters. <p> I'm not sure if it necessary, but if the game tends to end in draws even with the stalemate rule, you could also add victory by Bare King.

I have been studying the advices in this thread and examining some of 
my ideas along this line. The following is what I have developed so far:

Pawnless Chess

-by Jianying Ji			

Introduction:

This variant is inspired  these primary sources: 
1: Kevin Maroney's Ur Chess
2: Ralph Betza's Halfling Chess

One of the main motivations of this variant is similar to that of Ur Chess
in that I was looking for a 'simplified' variant of chess. As I read Ur
chess I saw that many of the fiddly rules he was trying to change concerned
pawns, so it seemed natural to me to dispense with pawns alltogether. But
that led to an immediate problem, which is with the major pieces of FIDE
facing each other the opening usually end up with a lot of exchanges and
not many pieces on the board after the exchanges end.  To combat this, the
pieces needs to be weakened and captured pieces recycled. So I used
halfling chess to weaken the pieces, and added the capture return rule to
recycle the pieces. I changed the knight to halfling Knightrider to
strengthen the army a bit so that it won't be too slow. The details
follows:

Board and Setup:

Use standard chess board and setup with the pawns removed

r n b q k b n r
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
R N B Q K B N R

Rules:

1. All pieces move as they do in halfling chess, except the knight, 
which becomes a halfling knightrider.

Motivation: To weaken the pieces so the opening will be more strategic,
rather than tactical. As Peter Aaronson suggested and Ralph Betza showed.

2. A captured piece is returned to the owner, who is to put it back on 
its starting rank. It is the owner's choice, which open square to put 
the returned piece on.  If the starting rank is fully occupied then 
the captured piece is discarded.

Motivation: Since the ratio of pieces to squares is so low, to start 
with, this rule will keep more pieces in play longer, for a more 
tactical and longer endgame.

3. No repetition of a previous board position

Motivation: Super-Ko rule is adopted to reduce draws.

Object:

Checkmate or stalemate the opponent

Motivation: Stalemating the opponent is included as a winning condition 
to reduce draws.

Notation:

R        a1        x           a5  	         [a8]
piece	source   capture    destination    drop location

piece: name of the piece
source: starting square
capture: x if capture occured, - if non-capturing move.
destination: ending square
drop location: the location to which the captured piece is dropped

Can be abbreviated if no ambiguity arises.

Remember, if capture occurs, drop location must be specified.


Comments:

Shortest fool's mate is 2.5 moves, which is comparable to FIDE, 
with the added benefit of being more 'foolish'.

Tempo is most important in this game. Losing tempo can be fatal. 
It is even more important than safety of specific pieces. Since 
pieces are recycled.

I have done some playtesting but I would welcome more. And any
more suggestions!

In order to prevent the upper levels from being clogged up, perhaps I
should introduce a gravity rule:  before a player moves, all of his/her
pieces that both (1) haven't moved in the past two turns and (2) have an
empty square directly below them descend one level.

Or perhaps, when an elevation isn't possible, a 'captured' piece could be
placed on any empty square chosen by the capturer.

MY personal preference is for CV proposals that contain a minimum of

I'm OK with very brief comments that actually simplify learning the rules,
but I have very little interest in extended narratives.

John Lawson wrote on Fri, May 17, 2002 05:21 AM UTC:
I went back and reread Pizza Kings, and it's better than I remembered. 
Pizza Kings actually had a definite satirical purpose.  At that time,
people were suggesting various different armies with themes like leaping,
or spaciousness, or fizziness.  I just extended the theme to something
completely irrelevant to chess, and then developed the theme deadpan.  Part
of the point I was making earlier is that sort of thing is only pleasing in
moderation.  If I had gone on to invent the Avenging Appetizers and the
Beer Batterers, the result would have been far less than three times as
amusing.

I was also unclear in stating my preference.  I much prefer an entertaining
and engaging description.  I am one of those variantists who actually
rarely play, but, concurring with gnohmon's point, I found Nemoroth so
fascinating that I am actually playing an email game.  That is based on two
things: the terrific description, and the original mechanics.  In the case
of Nemoroth, they cannot be separated.  Without the story, the mechanics
would seem capricious.  Without the unusual mechanics, the story would just
be an exercise in cleverness, without point on the CVP.  Now, e.g., there
is a clear picture in my mind of a Leaf Pile, what it does, and why.

Pizza Kings is a charming piece of somewhat humorous literature; it won't
make you laugh aloud like 'The Literary Offenses of James Fenimore Cooper',
but it may bring a smile.

Many variants recieve very little play, while others become popular. In
order for a variant to become popular, people have to try it at least once.
How do you get your reader interested enough to try playing the game?

A good presentation can't hurt. At least if it's interesting to read,
people may read it all the way through, and that's a start.

Sometimes the idea of the game is sufficiently intriguing in its own right
that you get people to play it without anything special in the way of
presentation. 'There's nothing in the way of presentation, you can get
right at it.' (That's from _It's a Gift_, right?) This was the case with
Avalanche.

A good presentation is Partonesque. His games were always introduced with a
bit of a premise and a bit of whimsy.

In other words, like all good literature, it's advertising; or even product
placement, as in Refreshing Bubble Fizz Chess.

I had a point here somewhere, but it wandered off. Perhaps my point was a
neutral piece and my opponent moved it somewhere I can't see it.

Having had time to think of my earlier comment I am almost entirely sure
that I lost the point, the reader, or both.  I'll try to keep it short this
time.  I completely missed one of the points that I had wanted to make.  A
discription with just the rules can be writen in such a way that the author
puts their own tone or flavor into it, this gives the reader a feeling that
the author is speaking to them.  This effect is helpful because for some
reason it is easyer to understand the same information if it seems like it
is said to the reader, it is also easier to remember.  This probably
doesn't make it all the way to literature, but it is somehow more than a
barebones discription.  This somewhat goes with what John said about it
being a kind of conversation.

John Lawson wrote on Wed, May 15, 2002 05:56 AM UTC:
Although the format of the CVP is like a database or encyclopedia, I think
that it is actually better thought of as a 'conversation' about chess
variants.  Many variantists probably actually play very little, and most
variants receive very little play.  Therefore, the main point of the CVP,
at least for some, is the communication of the ideas behind the variants.

As in any 'conversation', although the primary focus is to impart
information, a desire to amuse, entertain, and interact is perfectly valid.
 Also, some variants are better understood with the story that inspired
them.  A bare-bones exposition of the Nemoroth rules would seem
incomprehensible and arbitrary.  Other variants that are hard to appreciate
without their background stories are Peter's Ruddigore Chess, or Dan
Troyka's Hitchhiker Chess.

One is on thinner ice with descriptions that are just plain silly, like my
Pizza Kings.  It is important to avoid a descent into pointless sophomoric
humor, like the relentless plays on words in the headlines of bad
newspapers.

We should also remind ourselves, when writing rules, that the CVP has an
international following.  Therefore, it is likely that the point behind
Ruddigore Chess is completely opaque to someone with no knowledge of or
interest in late 19th C. English musical theater.  We also have to be
careful not to obscure the rules with verbal cleverness.

The beauty of the recently improved comment system, is that it provides a
forum for those so inclined to play with words and concepts, without
getting in the way of the clarity of the descriptive pages.

I think I might have had a point once in all this, but I ignored it and it
wandered away.  I like clever and amusing literate writing.  I think it
enhances the CVP, but it is not necessary to the CVP.  Intelligent,
well-thought-out, and clearly described variants are what is necessary.

ChrisWitham wrote on Wed, May 15, 2002 01:14 AM UTC:
I think that it depends opon the variant and the wirteing style, a bare
bones rules would be preferable to a badly writen naritive which has the
rules in it, on the other hand a sci-fi/fantasy based varient would seem
stale or flat without somekind of backround.  And when it comes to
background there is a very large gray area, becuase you could easily say
that why a piece was chosen to move the way it does is part of a bare bones
discription, but sometimes the reasoning is so complex it could qualify as
literature.

There is also a question of 'What is literature?' a common question is 'Is
a comicbook literature?' in this case it might be better as 'Is a
discription literature?' some would say yes, others no.  Certainly I would
always prefer a discrtiption into which some kind of tone or voice has been
put, but that is not the same as haveing something on the level of Ralph
Betza's Nemoroth, which gives you the feel and atmosphere of the game.  If
everyone could write on that level then we would have an impressive
colection of CVs and literature in one, and games that otherwise might have
been overlooked would be noticed and played.

I fear that I may have lost track of my point near the first or second line
but if I try and go back and change it this will make even less sense. 
Basicly what I'm saying is that a well writen back story or setting could
never hurt a discription, and in some cases it's absense would.  Also a
discription its self can have a certain literay flavor to it that makes it
easier to read and understand than a bare rules only format.  I think that
the most disireable form of a discription is first and formost the rules,
backround information on how the game came to be and why the pieces are the
way they are, and any story or such thing that goes with it, i.e. a game
claiming to be elven chess should say a bit about how the elves played the
game.  If the rules are mixed in with the other elements, like for example
as in Nemoroth it may also be a good idea to have them listed sepreately,
also as in Nemoroth, so that those that don't want to read the non rule
related elements don't have to, and those that want to quickly refrence a
rule can.

I know I rambled and I hope it made sense and was in some way helpful.

Until the late 19th Century, Geography (with the exception of Cartography and related disciplines) was primarily a descriptive science, and could be and was looked at as a variety of literature -- the literature of place. A piece of geographic writing was judged almost as much by the quality of its writing as the correctness and completeness of its facts. <p> Chess variants as described in these pages are a combination of rules and description, of algorithm and literature. While I would hardly suggest that the quality of the writing is anywhere near as important as the quality of the rules, yet sometimes the writing is very good. If you search through these pages, you will admittedly, find many bare-bones or clumsy descriptions of Chess variants. Often it is not the fault of the author, who may be laboring with a foreign language, or simply not have time or writing experience for the type of description they would like to produce. And opinions vary; as editor, I have corresponded with authors who prefered a very minimalist presentation of their designs. But still, if you wander through these pages, you will find stories and jokes and puns, references to arts and popular culture, small essays on the processes of designing and playing games, and snatches of biography and history. Sort of a literary smorgasbord. <p> Does all of this additional material add or detract from the rules that are the <I>raison d'etre</I> of the pages in the first place? Do readers like their Chess variants straight, or with a splash of story?

Doug Chatham wrote on Tue, May 14, 2002 12:27 PM UTC:
I've recently had a strange idea for an 84-square chess variant, and I'd
like to get some comments on it.

I call it Three-Layer Wedding Cake Chess.  The bottom layer is a standard
8x8 chess board with the standard chess piece placement.  Above the middle
16 squares is the second layer, an initially empty 4x4 board.  Above the
middle four squares of the second layer is the third layer, an initially
empty 2x2 board.

The goal is to get your queen and king on the top layer before the
opponent's king and queen can reach the top layer.

There is no check, checkmate, or any true capturing.  A piece (including
P,R,B,N,Q, or K) can move onto a square occupied by an enemy piece only if
the square immediately above that enemy is empty.  When such a move occurs,
the enemy piece is 'elevated' to the square immediately above its current
positions.  If a player can elevate an enemy piece, he or she must do so. 
If more than one elevation is possible, the player can choose which one to
carry out.

A player may move a piece to the square immediately below that piece if
that square is empty.

Pieces move on the top layers just as they do on the bottom layer, except
that pawns may only promote on the bottom layer.

FIDE rules apply except as I've contradicted them above (so, for example,
there are no 3D moves other than the ones given above,).

Previous variants inspiring and influencing this one include Bachelor Chess
(the wedding theme), Pyramid Chess (board layout), Reenterent Chess (each
square on the top two layers acting like a reentering square for 'captures'
on the square immediately below), Losing Chess ('captures' compulsory), and
Elevator Chess (inspiring the term 'elevate').

I hope you find this entertaining.

Phase 2: Take HJR's 'History of Chess' and Guten-ize it (ie. produce an ebook version). Of course, phase 2 would be a huge job. Anyone know if these two books are public domain yet? HoC was published in the early 1900's. If anyone else is interested in doing this, I could check with the folks at PG. <p>Thinking smaller... perhaps a timeline page or chess geneology page.

Continuing what Ralph said about the need for more prominent heading for
chess history. One possible idea is a specific page on the history of 
chess that shows a genealogy of chess. A genealogy because it shows both
history and the relationship between the different historical variants.
Such an undertaking would be no small one by any means but would provide
a good context for the layman and scholar alike in the foundations of 
this pusuit of variants.

'I'm glad you like these questions' -- I have always (well, at least since
I started publishing CV writings in the early 1970s) appreciated the
value-added that asking these questions can give to your new game.

Before you ask, you should either know the answer or suspect that the
answer will be really interesting.

The 'standard' questions are::::::::

1. Shortest foolsmate (for some games, shortest victory)

2. Shortest doublecheck (triple check, quadruple check, etc.) with or
without mate

3. Shortest stalemate; 4. shortest stalemate without capture (the great and
brilliant and superhuman Sam Lloyd solved these for FIDE Chess; if you
don't know his solutions, look them up and you will feel the emotion known
as 'awe' -- really, no exaggeration, awe.)

5, shortest perpetual check, 6. others appropriate for specific variants.

Glad that you like these kind of questions. I thought it might be fun

Short and sweet. Quite amazing really.

'Note 1 Be2 Bd7 2 Kf1 Ra7 3 Qe2 Ra8 4 Bh5++ is shortest doublecheck
mate.'

the 3rd move doesn'T make sense.

After the second move we have

. n . q k b n r
r . . b . . . . 
. . . . . . . .
. . . . . . . . 
. . . . . . . .
. . . . . . . .
. . . . B . . .
R N B Q . K N R

Qe2 is an impossible move, however I think you intended Qe1

which works.

It is interesting that both of these are helpmates, I wonder if a
computer
mate as I defined can be found easily, or does it really need a computer
to answer that questions.

With Pawns replaced by W or F or Berolina Pawns, in a sense it's not so
Pawnless, is it?

Racing Kings is Pawnless. It has a different goal, and perhaps you could
argue that it's not even Chess. However, in the process of becoming NOST

Without using really weak pieces to replace Pawns, you could probably find
a setup on the 4x16 circular chessboard that works.

wouldn't it be a good game. Or in other words what is the mininum that
can be done to make it a good game.

Peter Aronson wrote on Fri, May 10, 2002 04:05 AM UTC:
I don't think simply removing the Pawns from the FIDE array would make a good game.

Experimentation is certainly the key here.

Continuing with this subject let me propose the following:

let their be 9 levels of mastery (similar to asian game ratings, but 
                                  in keeping with western chess theme,
                                  we need a different name than dan)

Between each level and the one below is divided 4 sublevels. 
(Again a name is sought)

The difference between sublevels is one point, as described by Ralph Betza

in  http://chessvariants.com/d.betza/pieceval/p3-01.html.  The move is 
good enough for difference of one sublevel.

The difference between levels is then naturally 4 points, or pawn and
move.

For other handicaps we need to temper with the army somewhat, but 
whatever we do must be ballanced, from openning to endgame.

Also as can be calculate, I envision the largest handicap to be 36 
points, roughly the value of an amazon. I think this is a reasonable
 upperbound but as I am not a good chess player, input would be really 
appreciated.

I usually think of the game first and then try the Zillions implementation.
The result is, sometimes, that the Zillions implementation is unwieldy. It
is true, though, that some I have not even tried to implement. 

There is a great alternative, and that is our very own (thanks to Fergus)
play-by-e-mail system which is available to any square or hex board design,
requiring enforcement of the rules by the players--like a table-top chess
set. 

As far as 'mentally' creating games. Yes, when the game idea is very
interesting, I find myself mulling over it and the game design works itself
out conceptually--to a large degree, however, not completely. There are
some details of playability that only work themselves out in playtesting.


Zillions is a great way to work out the playability of a game, at least as
a first step. One pitfall that Zillions has is that the farther a game is
from orthochess the poorer the Zillions engine plays the game. Some games,
it plays very poorly, some in a skewed way, some extremely well.
Ultimately, play against a person is best for testing. 

If one is interested in play by e-mail, a Zillions implementation can be as
basic as a board and pieces that can move on it, without full rules
enforcement--this liberates many of the programming restrictions--since it
does not matter how well Zillions itself plays the game.

Back to the orginal question: I have found that in some practical ways,
Zillions does 'suggest' the development of a game because of the
programming practicalities. But I would not say that it inhibits ideas
altogether. There is one game I would like to try but have not found a way
to play by e-mail: Star Trek 3-D Chess (the 'real' one with the shifting
boards!) Any ideas?

different armies of ralph betza points the way forward. Black Ghost of
Ralph Betza is a step toward a handicap system. Using these as stepping
stones, let me propose the following:

Types of Handicap:

Range: Gradual limiting of the range of stronger player's pieces 

Functional: Limiting the leaping/capturing ability of the stronger player

Balancing: Adding power to the weak side, for example adding of a ghost
 like in ghost chess.

Of course how a comprehensive system might look like, I'm not sure yet,
 so any comments welcome.

Both of you produce one interesting idea after another.  So do other

I have also perceived an attitude among some CVPhiles that a creation is

result, there may be ideas that are interesting or intriguing that do not

I hadn't worked with halfing Nightriders before -- it's a very nice piece. All halflings have shorter range the closer they get to the center, but the hhNN is more extreme somehow, moving like regular Knights when in the central 4x4 area. I'll have to use them somewhere else someday.

Well, I do worry about limiting my designs to what works well for Zillions. Of the 17 or so games I've published since I've learned Zillions programming, only one -- Transactional Chess -- has not been implemented with Zillions. This leads me to wonder what games am I 'self-censoring' in favor the ones that are easily implementable with Zillions. The games I designed before were often difficult to completely implement for Zillions; some would merely say that Zillions was simplify causing me to simply the games, which is all to the good. But there can be simple ideas that are not simple to implement with Zillions. Chatter Chess would be a great deal of work to implement in Zillions, for example.

As for the game, it seems a worthy endeavour, but needs to be clever or
else it will never.

'Mostly self-capture with the occasional threat'.

Idea 1. There is no problem. Sacrifice a few Pawns to build up an attack;
give checkmate, and win. You merely weren't sufficiently enterprising in
your play. (This idea could very well be false, but deserves to be
mentioned.)

Idea 2. Make self-capture less appealing than other-capture. Pieces go in
hand but are demoted? Something might work.

I had never thought of this effect, perhaps because I neither design games
nor write ZRFs (I entirely lack creativity).  I take this to mean that
ZoG-wise game designers will avoid designing games using concepts that
cannot be effectively implemented in Zillions-of-Games, thereby limiting
their own creativity.

At the same time, ZoG has been considered a tremendous boon to board game
variantists of all stripes, allowing them to play and test their
more-or-less obscure discoveries and creations without the need to actually
find and interact with other people.

So, the starter questions are, 'Does ZoG limit creativity?', 'If it does,
does it matter?'  What do you think?

So I eliminated the Bank Holiday, and made sacrifices required only on even turns (Sir Despard did all of his wicked deeds in the morning, and did good in the afternoon). This helped a lot, now you can capture your own piece on an even turn, and deploy it on an odd one. Now, though, I'm wondering if the Gentlemen are too powerful, since when dropped they can fork like anything. Maybe Halfling Nightriders? <p> I also find I'm tempted to rename everything: Pawns into Farmers, Bishops into Vicars, Rooks into Squires, and Queens to Stewards. But on the other hand, if the move hasn't changed, it is confusing to change the name of the piece. <p> Anyway, this is still very much an on-going project, and I'd appreciate any advice anyone has.

I use a very simple rule for detrmining what's an Ultima variant or not: if the author calls it an Ultima variant, it is; if not, it isn't. So The Game of Nemoroth and my game Interweave are not Ultima variants since they don't call themselves that (although Interweave describes itself has being sort of Ultima-like).

Examining this site and The Encyclopedia of Chess Variants, I find the following Ultima Variants:

  • Bogart's Chess, which replaces a Chameleon and a Long Leaper with an Absorber (which picks up the capture method of each piece it captures) and a Golem, which only moves two but has to be captured twice (this was the inspiration for Golem Chess).
  • Renaissance, which is played on a 9x9 board, and adds a Pusher, a Puller, a Resurrector, and a Bomb, and has a limited form of drops of captured pieces (using the Resurrector).
  • Stupid, where each piece can move like an Ultima piece and an Orthochess piece.
  • Ulti-Matem, except the Pawns have the moves of the Orthochess pieces they would be standing in front of, except for the King's Pawn which is a Double Knight Pawn which makes two Knight's moves in a row in any pattern.
  • Ultimate Ultima which you described in this comment system here.
  • Unorthodox Ultima, in which a Long Leaper and a Chameleon are replaced by a Neutalizer (which removes the ability to capture of adjacent pieces) and a Repeller which forces an opposing piece moved next to move as far away as possible.
So look at them. All of them at the very least add some additional types of pieces. All of them are more complex than Ultima. Although, no one has take the simple, logical, and completely insane step of combining Ultima and Chessgi/Shogi. Ultigi! Ultima with drops! Ah, maybe not.
