Fischer Random Chess. Play from a random setup. (8x8, Cells: 64) (Recognized!)[All Comments] [Add Comment or Rating]
Charles Daniel wrote on Fri, Jul 31, 2009 07:55 PM UTC:Excellent ★★★★★
Fischer is the 'inventor' because only he had the audacity to come up with this seemingly convoluted but quite logical castling rules. It is truly amazing that world caliber players are now playing this variant - it is really taking off. 

Treating the squares c1 and g1 as safety bunkers for the king - castling makes perfect sense .  

With this in mind, I have a new idea one i may submit soon regarding shuffle chess. An alternative to castling,  King's leap to the b or g squares (from any position in backrank), applicable to shuffle chess and seemingly never 'invented' before in the 'exact form' i propose. In conjunction to Fischer random castling slightly modified - I call this new system: King to Bunker Leap. It is applicable to shuffle chess and to pre-chess. 

There are many who would differ that 'Chess 1' is exhausted though. I tend to agree to some degree, with the caveat 'for high rated > 2000 elo' or for  those not willing to specialize in 1 game. 
Try 'exhausting to compete in' instead. 

Excellence in Chess 1 translates almost directly to full capability in 960 with some debacles because of unfamiliarity with weird angles and so forth. 

Nakamura could very well be future world champ. But Anand competed very strongly in this event losing to Aronian years back. 

Note that computers win in chess 960 just as easily, but novelties/opening preparation not an issue here, though one can always attempt to memorize 960 position opening theory to some extent.

Another possibility, closely resembling Fischerandom chess, was advanced by GMs Pal Benko and Arthur Bisguier in two articles in the November 1978 issue of Chess Life & Review, and by me in a two-part article for Chesscafe.com in 1997

The positions of the pieces are decided entirely by the players, not by a computer program. Strategic chess thinking therefore begins with the first piece placement. The two players place their pieces alternately, one at a time.
White does not necessarily have any advantage here; in fact, Black may have the advantage because Black gets the first look at the opponent’s placements.

  • The pieces may occupy any squares as long as the bishops are on opposite colors. The kings do not have to be placed between the rooks.
  • Castling is permitted only if the unmoved king is on e1/e8 and an unmoved rook is on a1/a8 or h1/h8; orthodox castling rules apply. The possibility of castling is up to the players, who may or may not place their kings and rooks appropriately.
  • There are 8,294,400 possible opening positions.
Both variants obviate all opening analysis (but not opening principles) and make all opening manuals superfluous. Imagine a world without the Sicilian Defense! Should either variant become prevalent, chess-book publishers would have to take up gardening. But surely publishers will be resourceful enough eventually to put out strategy guides on choosing the optimum piece placements in Pre-chess (but not in Fischerandom chess, of course, because there the computer does the choosing).

Does someone have the original text of this article from Chess Life & Review by Benko? It seems quite important for historical purposes.


Seirawan ChessA game information page
. invented by GM Yasser Seirawan, a conservative drop chess (zrf available).[All Comments] [Add Comment or Rating]
Charles Daniel wrote on Fri, Jul 24, 2009 03:07 PM UTC:
Yes, but this is my point. The pieces are too heavy and most likely give white a huge advantage. Anyway, I saw the video of Seirawan introducing the game. From what I gather he seemed like a nice guy and quite honest though there is still a possibility that this variant was invented purely for profit  
which by itself is not bad but not with the flaws it has. 
Anyway, he seemed quite interested  in the new pieces but i get the feeling he has not explored the game in depth and not too interested if the game is balanced. For example he showed a mate in 4 which went something like e4 e5 d4 d3 pxp pxp qxq drop elephant mate. 
He seemed quite excited by that - and yes these things fascinated me when i started out with chess variants. But i have come to realize that very powerful pieces on a board while interesting have their drawbacks esp on a 8x8 board. 
Also you are basically saying it is an advantage to be able to drop the heavy pieces anytime so there should only be a few chances at the beginning.
I am saying though that the move followed by a drop is actually 2 moves. Why not simply keep the same restriction of introducing early but make the drop a separate turn? IN that case that mate in 4 could not have happened and white may not get such a huge advantage. 

Seirawan  also mentioned that their first idea was to have the pieces exist  on the board right from the beginning in a fianchetto and they rejected that idea. It seems to me that they did not playtest before and play around with the different parameters enough before releasing. 

Anyway this whole discussion gives me an idea for a new variant on an 8x8 very similar and in my opinion better. 


I really wish I could stop making variants -- 

and leave it to you to just make every conceivable one possible :) 


i guess the next 2  or 3 will be my encore and i am done for good ...

hopefully :)

Charles Daniel wrote on Thu, Jul 23, 2009 05:20 PM UTC:BelowAverage ★★
Not so. Dropping it on a separate turn does not allow the drawback you stated in your site. Why should a player not decide to drop a powerful piece? My suggestion allows one player to develop quickly without dropping the piece and still have that option in reserve. An altogether more flexible situation adding more varied type of play. In fact the game is VERY strategically clear to each player - either one or both players can choose to develop first gain the advantage and then introduce the piece.

I see no reason the dropped piece is 'FORCED' to make an entry soon. That makes the game more contrived and less flexible. If anything it is preferable to leave that up to the players. A good player will be smart enough to know that the opponent will eventually introduce the new piece. If a player is good enough to play without the piece he/she can dos so knowing that the option to introduce it still remains.

The game Wreckage uses this drop mechanism.

By the way your description for Pioneer Chess is faulty. IF White turns down the piece and Black overrules - no game can be played - both players disagree on what game to play.


Charles Daniel wrote on Thu, Jul 23, 2009 02:45 PM UTC:BelowAverage ★★
I am not sure why this method of dropping into the back rank was chosen. Its quite possible that white will have an even greater advantage because of this. Better to make the drop  as a separate turn. This seems more logical and slows it down a tad.  
Also I just realized I had commented on this item before. Looks to me that the ability to drop ninja pawns in addition to the rook-knight and bishop -knight might actually be more interesting perhaps 2 or 4, not sure.
The Rook-knight and bishop knight drop into empty space in backrank in separate turn. The ninja pawns can drop into vacant space in second rank and optionally push forward to center. The ninja pawns will move like pawns except for enpassant and ability to move 1 space sideways and also capture sideways in enemy half of board. 

At this point this variant has failed miserably even more so than gothic which i believe is far superior (and actually in retrospect quite a good variant). Perhaps the version I suggest above might be interesting - I wouldn't mind trying it. I may create a preset and send out a challenge. 


As to why does regular Chess have on the order of 10^4 to 10^6 times more followers than variant chess ..
Chess variants are parallel universes - completely unexplored with weird rules /laws and strange configuration. The regular chess universe is still unexplored and overwhelming for most despite the oversaturation of opening theory at top GM level. 
Chess variants are for those with moderate to little interest in regular chess and with no desire to compete with regular chess players. I doubt if there are currently is any 2100+ rated (at present) chess player interested in variants. Seirawan himself must have lost interest in his own variant just like Bobby Fischer lost interest in FRC. 

2100 chess rating is approximately the elo at which opening theory becomes tedious since many lines do have to be memorized. Some may say its even higher than that. Below 2100 and memorizing opening theory is not terribly important - understanding openings is of course a different matter. 

It is important that the chess variant community understand that nothing is to be gained by proposing to 'fix' chess or to 'convert' chess followers. 
Chess variants instead must attract the type of person who does not want to dedicate to one game and likes a chess-like family of games. Of course high rated players disillusioned with the game will be welcome but they must come on their own. 

Rather than harp on the nonexistent 'flaws' of chess, it is better to show how interesting it is to play a game of chess in which a few properties are changed. Board size, pieces etc making in many cases a radically different but still vaguely familiar game of chess. This is the appeal of chess variants. Think HORSE in poker - tournament of a family of poker games. 

A chess tournament like this can take place here too. The recent Cv Potluck  was a good start, and SHOULD BE DONE AGAIN.

Maybe one day the parallel universes of chess might appeal to a totally new audience. From that certainly a few chess variants will immediately spring to mind in the general populace just as orthodox  chess does now.

Chess with Extended Castle. Standard chess with extended castle rule, effectuating greater opening variance (with zrf).[All Comments] [Add Comment or Rating]
Charles Daniel wrote on Fri, Jul 10, 2009 03:22 PM UTC:
Displacement Chess 2 already has extended castle which allows king to make 1-3 spaces towards the king. Additionally it reverses the king and queen for one side. Displacement Chess 2 offers much greater opening variance than the change you proposed.

The 1 space castle allows king to remain near the center but connects the rooks and keeps the rook on the center file.

Adjustments such as this change the game considerably and the effect cannot be fully investigated without a considerable number of play testing.

It seems to me that the goal is to have two sides castle on opposite sides. Just reversing the king and queen for one side will have that effect.

Venomous. New system of chess on 10x10 board with new pieces: the Sorcerer Snake and the even more venomous Sissa. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
💡📝Charles Daniel wrote on Tue, Jul 7, 2009 04:54 PM UTC:
Thanks for you comments Joe and George. Regarding George Duke’s  ninja pawn comments: It is true that the complexity of the rules and/or the drop mechanism may put off some players, but the upside is a much greater scope for pawn play. Weakened pawns and pawn chains are characteristics of large board chess. Faster standard pawns and Ninja Pawns address this drawback as well as providing richer and unique endgame scenarios. The threat of quick promotion (by moving 2 steps forward) and ninja pawn lateral capture add substantial power to advanced pawns or ninja pawns in enemy territory. 
     Interestingly, Nahbi Chess mentioned by Joe, allows standard pawn to move sideways on enemy half of board, but this may not be sufficient to overcome the inherent weakness of pawns on larger boards. On Nahbi vs Sorcerer Snake: the Nahbi allows one path to destination squares so can be blocked easier while the Sorcerer Snake can choose an alternative path and is a bit harder to block.  On a crowded board, this difference can be substantial, on a more empty board not so much.

💡📝Charles Daniel wrote on Sun, Jul 5, 2009 07:39 PM UTC:
Thanks for your comment Jose. In response to your question - The bishops are already a bit stronger on a 10x10 board so maybe don't need improving, while a regular knight is a bit weaker. On 10x10, Zillions rates the wazir-knight a half pawn more than the bishop and the regular knight almost a pawn less than the bishop. So WN=B+1/2P; B=N+P; WN > FN > B > N

ZigZag Madness. Featuring the crooked dual path sliders: the ZigZag Bishop and the ZigZag Rook. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
💡📝Charles Daniel wrote on Mon, Dec 1, 2008 07:13 PM UTC:
Claudio, there is no limit to what I can or will consider in applying the template to other pieces. In fact, I would suggest you continue by applying it to other pieces as you see fit. I have no problem with that.

I reuse much of my original ideas discarding only what I see as completely unworkable. For example initially interested in Gryphon/Aanca I felt that they may be a bit too powerful on the board and so limited its power. The Hippogriff was too limited so I developed the Stealth Gryphon/Anti-gryphon for Stealth Ninja Chess.
However, these pieces could be powered up more by providing dual paths as the Duke/cavalier but with the same minimum square restrictions. Thus the minimum distance – the Zebra move for the zigzag bishop and the Camel move for the zigzag rook can be considered the atom as you call it. This configuration seems far more interesting especially since they are more susceptible to the knights despite their power.

The basic units have been used in many ways: compounding a single path stealth Gryphon/Anti-Gryphon to make the Octopus. Combining Knight and Zebra move with 2 paths as the Sorcerer Snake (See Octopus Chess). OR combining the Rook with the 2-path sliding camel move – the Snake Rook and similarly for the Snake Bishop. (Asylum Redux)

I reused the Flying Bomber that I developed as a compound of different “atoms” that already existed while introducing the checkers/draughts motif to a chess piece. The latest re-incarnation is the Flying Guillotine that you see in Wreckage.

Also see my Zillions file for Pick the Piece Big Chess that has many different ideas contained in a whopping 34 games.

So new piece movement that contributes to the aesthetic beauty of a new chess interests me, and this must be accomplished by experimentation, innovation, as well as reworking and improving existing ideas by others.

I will not have time to continue this work in the immediate future but you (or anyone else) are welcome to expand on my ideas.


💡📝Charles Daniel wrote on Tue, Nov 25, 2008 11:38 PM UTC:
Sorry George, 
But no one cares about your  patent. And the only piece you invented is far less original than the very many I have invented or derived from other pieces. 

What I do know from playtesting Asylum Redux, Octopus Chess and Zigzag madness is that the gameplay is far more satisfying than your clunky  falcon game. 

Still your comments are quite amusing esp your reference to yourself as 'we' . 


Keep up the good work.

💡📝Charles Daniel wrote on Tue, Nov 25, 2008 08:31 PM UTC:

George Duke, thank you for your comment, but there are many inaccuracies in them that I shall address.

Firstly, there never is and never shall be any need for an inventor to " acknowledge" every instance of "similar" piece that ever existed. In a few instances as in your persistent bringing up of this flawed “airplane” piece, there is absolutely no connection. I have always stated that the Flying Bomber owes its existence to Checkers / Draughts (and which probably the airplane piece too is derived from)

Secondly, since my ZigZag Bishop/Rook differs from the Duke/Cavalier in as much degree as your Falcon does from the Bison, there is no reason why I must bend over backwards and chastise myself for simply using the word “new”. I certainly haven’t patented the piece – and I suspect I could if I wanted to.

Thirdly, I never suggested nor agreed to have delayed evaluations - that suggestion was made by another poster.

Perhaps, the question that should be raised – Am I aware of the dual path Cavalier/Duke and was my idea derived from them? The answer is yes. Earlier I had used the pieces: the Stealth Gryphon and Stealth Anti-Gryphon which are limited versions of the Gryphon and Aanca. Some logical steps for new pieces: Compound the Stealth Pieces to give the Octopus. Or make them 2 path go give the ZigZag piece set. I also played Renn Chess so I was aware of their existence. I was simply NOT particularly inspired by Renn Chess or its two pieces which itself are derived from Gryphon/Aanca.

You are free to mention what you think are similar pieces, but ultimately it is up to the inventor to state his/her inspiration regardless of whether you think he/she is being truthful or not.

As for Proliferation – this can only be a good thing in the long run. Unfortunately, I am ending my run at proliferation. My variants were created to fill what I saw as a void in chess variants whose gameplay most resembled orthodox chess. And I do believe the dropping mechanism of Ninja Pawns fulfills this more on a 10x10 board than pushing the armies closer as in Grand Chess or by using a 10x8 board.
And I just don't buy the claim that the quality was so much higher in the first decade. This is a myth. What was invented earlier can be and has being improved upon.

I sincerely hope that others will continue where I left off – which is mainly adding one or two pieces to 10x10 board and strive for balanced gameplay.

Hey Claudio, 

Thanks for the rating but I am afraid I do not follow you. 

Your previously mention:  'But, looks to me that is a template, as the snake. A template that can be applied to the various atoms and generals.'

I guess you are right, this template or formula can be applied to other types of pieces. Of course I used this idea in Asylum Redux and Octopus Chess as well. 

I did not realize you were asking me a question. Would you care to elaborate on this a bit more?

💡📝Charles Daniel wrote on Fri, Nov 21, 2008 06:43 PM UTC:
Larry, thanks for your comments, they were most helpful in dealing with the confusion. 

I think the problem is the poster's unshakable belief that only the Boyscout can be a zigzag bishop  (even though I and some others may not find the term 'Bishop' as referred to the boyscout intuitive) 

I don't think the comments need to be reviewed or delayed as long as they are not overly obscene. As the site gets more popular, the quality of comments may very well decrease as in YouTube, but this is the price to pay so that anyone can voice their opinion.

💡📝Charles Daniel wrote on Fri, Nov 21, 2008 04:29 PM UTC:
To anonymous poster: I don't care too much for jargon and neither should anyone who is interested in playing this chess variant. If you had really wanted to contribute terminology, you could have just done it, I have no problem with that.  Instead you resort to attacking the variant while hiding as an anonymous poster. 
My chess variants are geared  more for the mainstream, which is why I try to avoid using jargon when simple words can do. Its a 2 path bent rider but only people in chess variants understand the term bent rider. 
2 path bent rider=crooked dual path slider. 
The word crooked is more readable for the general audience. 
The word Zig Zag is already proven to be corrrect in the sense, so this topic is now moot.

There is nothing counterintuitive about the array - the unprotected pawn is easily defended by the wazir knight in one move. 
If you look at the opening example you will also understand the starting positions of the ZigZag pieces 

Many chess variants have one or more unprotected pawns - why not criticize them as well?

💡📝Charles Daniel wrote on Fri, Nov 21, 2008 02:26 AM UTC:
Handicapping them close range does make them less powerful and more on par with the other pieces. However, there were other reasons: as I mentioned their minimum distance a camel or zebra move away, make their movement more  unique on this board. THe two new knights already have a  Ferz or  wazir in addition to  knight movement. The Zigzag Bishop/Rook are thus more susceptible to the knights and pawns. 

The piece values from the Zillions file (which will be up soon):

Wazir Knight - 13860 
Ferz Knight - 13287 
ZigZag Biship - 13914 to 11590
Zigzag Rook - 22078  to 17733
Rook - 17292 
Bishop 11613
pawn - 3620 
Ninja Pawn - 5915

💡📝Charles Daniel wrote on Fri, Nov 21, 2008 01:10 AM UTC:
Note that the minimum distance a ZigZag Bishop moves is a Zebra's move away: One orthogonal and TWO diagonally outwards. 

Think of it as a zig  then a zag followed by 1 or more spaces along the diagonal as a bishop. Or it slides 1 or more like a biship first and then zags 1 more in same direction and then zigs. 

ZigZag Rook's minimum distance is a camel's move away Two orthogonal and one diagonally outwards. 
So its 1 or more spaces as a Rook followed by a zig in same direction and then a zag. 
Or a Zag diagonally then a zig and then moves 1 space or more like a rook in same direction. 


So not only they cannot move to adjacent squares, they cannot move to squares a knight's move away. (This is unlike the duke and cavalier that can move a knight's move away.)

💡📝Charles Daniel wrote on Thu, Nov 20, 2008 02:56 PM UTC:
It IS a crooked slider and it is a zig zag motion as most people UNFAMILIAR with these pieces will understand it. 

e.g  One step orthogonal (zig) followed by two or more diagonally (zag) ..



Apparently you are just interested in semantics.

Actually the dual path pieces here are a bit different from the duke, cavalier. Its more like a dual path zebra compounded with bishop and a dual path camel compounded with rook.

Note - The Ninja Pawn can be optionally pushed forward (1-multiple spaces) towards the middle during the same turn.

Thus, one can develop a pawn, and then later drop and develop a ninja pawn (with attacking possibilities) in one turn.


💡📝Charles Daniel wrote on Mon, Oct 13, 2008 03:07 PM UTC:
Larry, 
The problem with the regular pawns starting on the 3rd rank leaving the 2nd rank vacant (or filled with Ninja Pawns), is that this allows a double row of pawns which tends to clog the game  a bit I think. 
See Herculean and Hadean Chess in which the pawns are one row advanced with ninja pawns behind - its not too bad, but I was not too happy with that configuration in the end.
Many 10x10 variants do have start configurations with more than 2 rows but they normally use more powerful pieces not extra pawns. 
I think allowing extra pieces and pawns via gating/dropping allows more flexibility in the setup and keeps the original configuration more harmonious. 
Because the Ninja Pawns have to be dropped in the 2nd rank, the player is forced to move the regular Pawns first, thus favoring more aggressive type openings and advanced pawn chains. 
As it stands, the Ninja Pawns reinforces the pawn structure that can extend right towards the middle or even into enemy territory.

I have done a lot of chess variants, so there is no way that I am
personally putting chess over chess variants but ...
I am commenting on what I observe in the chess world and I don't see what
you guys claim is happening. 

For Bobby Fischer chess was dead, when he realized he could not re-enter
competively - that was his personal problem 

The chess forums, online chess world is alive and well - they hate short
draws (the GM draw), but no body cares if half the matches are contested
draws . I find it strange that this faulty argument keeps getting re-used.

Any good player will tell you, if you can keep drawing your chess games
with ANY chess player, you are one of the worlds best. 
It is precisely because of this that the WC match format is so exciting
and some like it to be about 24 games not 12. A WC match is like 2 boxers
fighting a 12 round match with one gaining just enough to win. 

Most chess has moved online now. But if it is declining - it does not bode
well for chess variants. Grand Theft Auto or some othe frivolousgame is in
vogue.  


And what is speed chess? Isn't that Blitz chess?

What is true chess? What is the most efficient way to learn Chess? 

These arguments just seem nonsensical to me.  - 

Where is this new 'game' that is taking over that we now have chess die
hards? It seems to be that the same old arguments are used by about 3-5 of
the SAME  people on various internet sites.

Charles Daniel wrote on Fri, Oct 10, 2008 05:04 PM UTC:
Actually, the reality for ortho chess players is simply: 

'Every top chess player has his own way of dealing with the computer, to
use this incredible instrument in the most efficient way, for himself.'

The computer is simply an instrument that makes analyzing lines easier -
in the good old days, the GMs need to utilize the best seconds instead of
computers. Thus, in some cases you may not even need 'Seconds' to home
prepare. And many players can improve their game because of the computer.


In previous interview, Anand already explained that ortho Chess has a much
longer life than the doomsayers have predicted. 

And to clear up something - Computers have not mastered chess. It is
programmers who have mastered programming the computers to play chess. 

And since the majority of chess players have NOT mastered chess and are
NOT bored with it - this constant 'death of chess' topic is only brought
up by those who have given up chess or by weak players who do not
understand the game, have given up,  and  hate the game.
