New thread of Demonstrations that Marshall(RN) & Cardinal(BN) are fatally flawed, to be extended. DEMO (I): Dave's Silly Chess Game (2x2)
  2 q_k                 2 m_k       2 c_k  
  1 K_Q  makes sense.   1 K_M  and  1 K_C  do not.  Think about it.
DEMONSTRATION (II): Conclusion of 'Multipath Chess Pieces':  'Beyond
chronology, any rule of movement writ large, having real-world counterparts allegorically, describes something multiform and multipath, whereof reduction to mere leaper or rider is actually the special case'. Thus the NORM is multi-path. A piece that moves to only (1,2) (1,3) (1,4) and (1,5), conventional Rook squares, called by Betza Short Rook, moves stepwise like Wazir. But that is only one possibility. For example, 'Sissa', moving any number as Bishop and same number 'orthogonally in one direction', also reaches Rook squares: e1-f2-e2, e1-f2-g3-f3-e3 and so on. Sissa is two-path to Rook squares (e.g., e1-d2-e2 etc.)  In reality, there are innumerable pathways to each Rook square. Frivolously, 'Earthquake' goes 13 straight forward, 12 diagonally backward and 12 cross-horizontally to Rook (1,2). Also an example, specifying an unnamed piece moving e1-f2-e2-f3-e3-f4 and so on being two-way also to Rook squares, differently from Sissa. Once specifying a path such as e1-e2-e3-e4-e5-e6-e7-e8, it establishes an extreme no longer normal 'multi-path', in this case, a Rook Slider, one-path. VERY OPPOSITE EXTREME is no pathway at all, a Leaper, such as Dabbabah to (1,3) or Trebouchet(1,4), or Camel(2,4). There would be innumerable multi-path alternatives to any of those target squares of prototypical Leaper, all become inapplicable, once defined as such.

DEMONSTRATION (II)conclusion: In the multi-path model, Marshall
(Knight+Rook)is of itself kin to combining apples and oranges, elements
from the extremes of the categories. (Knight+Camel) is properly a compound of leapers. Knight plus Zebra is a compound. Rook+Sissa is a compound, in
part, making three-path to Rook squares.  Cardinal(Knight+Bishop) is a
'pseudo-compound', having combination rules of movement for patenting
and also everday purposes. Neither do we consider Bishop+Antelope(4,5 leaper) a compound, but a combination piece. Antelope does not augment the Bishop's move with a pathway, as for instance Crooked Rook would. Disparagingly, 'pseudo-compound' fits also because of improbability that movements combining powers at opposite extremes, namely leaper and one-path slider, could be very effective within one piece. Hence their unpopularity. The term is in nature of argumentative style because more important is accurate description of the rules of movement. So, in our system, there are compound leapers and compound sliders(like QUEEN!) and compound multi-path movers(FALCON, SCORPION, DRAGON, PHOENIX, ROC) and others(like riders), but no compound of Leaper and Slider. Marshall or Cardinal as compounds are misnomers and rather combination pieces.

Joe Joyce wrote on Mon, Aug 20, 2007 01:24 PM UTC:
George, you've got some things going here that, naturally enough, I don't
fully agree with. Let me start by taking issue with the following quote:
'Disparagingly, 'pseudo-compound' fits also because of improbability
that movements combining powers at opposite extremes, namely leaper and
one-path slider, could be very effective within one piece. Hence their
unpopularity.'

Contingency, historic accident, is a poor base on which to build an
argument of inevitability, and buttressing it with an unsupportable slight
does not help convince the skeptical reader. That a piece is worthless, or
at least worth little, if it is not in current use by millions of people,
is at least historically demonstrable as false. New pieces do arise and
are not always popular at first. Think of the genius who first invented
the knight move; and then wonder just what his/her friends thought and
said the first time that crooked jump move was used on them. How popular
was that piece in the beginning?

The piece I wish to consider is the combination dabbabah-wazir [DW]. Let
me hasten to add that I don't expect this piece to take the place of the
knight in 100 years, or anything close. But I do wish to examine some of
the potential for this apparently unprepossessing piece, very specifically
because it combines a leaping and a non-leaping component. The DW has as
its basic moves a 1-square slide or a 2-square jump. If allowed to use
both halves of its move, it leaps and steps 1 to 3 squares, an inclusive
compound piece [DHowe 'A Taxonomy']. If the piece instead repeats its
basic move once or twice, it becomes a limited rider and may move up to 4
or 6 squares. The 3 step DW rider is an interesting medium-range piece
that I have not seen examined in any games. I don't have a real
combination leaper and multi-square slider there, but the piece may leap
once and step/slide 1 square twice in its move, or even slide 3 squares as
its move. Will this piece do as a counterexample, George?

George Duke wrote on Mon, Aug 20, 2007 03:53 PM UTC:
Thanks for excellent input and we agree 100% with JJoyce's except one
mis-read: instead, 'pseudo-compound' is nothing but innocent undiplomatic, vernacular synonym for combination piece. Yes, very good interesting piece. Chatham's replacements, in our system, are to be developed in Demos III through XX against Carrera's stock.

George Duke wrote on Tue, Aug 21, 2007 04:34 PM UTC:
Waiting on DEMO III against Carrera stock Champion(R+N) and Centaur(B+N),
this thread wants to show they are incompletely-examined implementations to those (2,3) plus (1,2)(1,3)(1,4)...squares. JJoyce's generic DW,
Dabbabah-Wazir, he describes in number of different implementations.
Broadly, they are all 'sequential pieces' whether there are two or three
legs, whether repeat Dabbabah-Dabbabah is allowed, and so on. If memory
serves, Antoine Fourriere deleted a Comment in 2004 saying he prefers a
piece moving to Falcon (2,4 and 3,4) squares by way of two legs: Knight
leap then mandatory one-step outwardly to those (Camel) or (Zebra) arrival squares.  Differently, JJoyce's legs up to three for this DW are optional.
AF's description would also include recent Sissa in the same group of 'mandatory sequential', but 13th C. Gryphon would fall in JJ's 'optional'. Sequential piece, Multi-path piece, Leaper, Slider(one-path) are four fairly distinct categories. No full taxonomy attempted like RBetza or DHowe['A Taxonomy']: ''venture too deep into the jungle of classification''  we used in year 2000 FC article. Now for convenience, we call stock RN and BN 'combination pieces' because made of Leaper+Slider, functional opposites, but 'pseudo-compound' is descriptive as well. Any Leaper is a multi-path form with an infinity of paths, therefore no path at all in automatic shift to an arrival square(s).  Any Slider one-path has the potential for other pathways that could be added to piece-move definition. Therefore, multi-path is the linking category or organizing principle. Even the above sequential pieces are built according to definition of particular multi-pathers' units.

Given that the Mad Queen as such is dead. Like many-headed Hydra, a new
Carrera derivative most every decade since year 1617. Is Carrera's worthy
companion piece? A Hera? Or only weak sister, lady-in-waiting? To extent
JJoyce's Comment about 'Rhino' relates to this M/C thread, it suggests
Mao and Moa compounded with Rook and Bishop respectively, instead of
Knight with either. No secret then where we may well he headed: in place
of awkward combination pieces NR and NB, instead overlapping sliders, like Queen itself, making true compounds. We accumulate the evidence in DEMOS,
no one necessarily more or less convincing in itself, toward a preponderance of evidence. DEMONSTRATION III: On 3x3 board and all larger

at least two unsymmetrical unprotected Pawns, without positioning Champion and Centaur themselves unsymmetrically. That Pawns may subsequently be protected by other piece placement is irrelevant. This asymmetry here again being sign of certain imbalance, or disequilibrium, in power distribution among the pieces.

Get a feel for how there is simply no subtle move-order for White to consider: Queen first only makes it mate in one or two instead. Whether Marshall goes -e4, -e5, or -e6 same outcome; ponderous, is that not so?  Just play abstractly the doomed line of bowling pins across Rank 4 for the awkward constraint RN/BN pair tend to impose. As infinite in variety as tired 8x8 itself they may be, yet Cardinal/Marshall 8x10 positions typically present such rather uninteresting interactions.  Cannot future composers find more promising piece material for their skills to work? Are there not some other optimizations than top-heavy ancient Carrera-Centaur and Carrera-Champion?

Joe Joyce wrote on Fri, Aug 24, 2007 11:22 PM UTC:
George, you just might be looking for shorter-range pieces!  :-)  
On a 2D square-units board, there are only 2 kinds of 'shortest
distance' infinite sliders, the orthogonal and diagonal, rook and bishop,
with the queen of course being both. [For a different take, Graeme has got
some interesting things going on a triangular board.] This doesn't leave
many options for variety. What you do have are 2 pieces that travel the
maximum linear board distance in the least number of squares possible, a
'straight' line of n-1 squares with n = board length. If you're going
to cover the same [maximum linear] board distance with a new slider, then
the path that slider takes must be longer and more complex that that of
the R or B. This makes the game harder, and your critique - who in the
real world will play it? - applies. So sliders may have to either be of
shorter range or dropped entirely. [One very simple longer-path slider is
the 'hook-rook', a bent rook that can cover the entire board potentially
in one move. But you don't want that kind of power, I suspect.]
Obviously, we both lean toward shorter range pieces, you with the Falcon
and me with a proliferation of pseudo-shatranj pieces. But I'm curious
just where you're taking this longrange thing, and I'd like to examine
the potentialities of the DW as a longrange piece - in another post.

Over here 20.August.07 JJoyce says, 'Think of the genius who first

first time that Crooked jump move was used on them. How popular was that
piece in the beginning?'  Well, In the Beginning, were the Knight, Rook
and King -- to be brief and reductionist, not entirely inaccurate
metaphorically either. So, those semi-ideal 'friends' would have been
well used to the Knight, not the other way around. PAronson may know more
about appearance of Knight, or Rook, or King, in early board games Before
the Common Era. Pertinently, Shatranj, and Chaturanga before that from year 600, have only those three movers perfectly the same of the six-piece-type method. That generality was the main objection to couple of JJoyce offhand remarks. [Royal Falcons etc. being studied]

The point you are trying to make escapes me. What the heck do you mean by
'with the latter determinin who moves first'? K + (BN) vs K is a totally
won end-game even on 16x16. With white to move, there are no draws. With
black to move, there are of course always draws when the blck King can
capture an undefended (BN), and it dos not care much if it was a (BN),
(RN) or Q it was capturing...

Some of your other aguments seem to be directed against (BN) and (RN)
occurring only once in the Capablanca (and related) setup. It says nothing
about the pieces per se. You could have said exactly the same thing about
Rook and Bishop being fatally flawed, if you have one of each (like in
Shogi). Or the Knight and the Falcon.

It just doesn't make any sense. So the Cardinal and Marshall are mixed
slider-leaper compounds. So what? You seem to judge pieces by the abstract
symmetries underlying their design. But the rest of the World judges them
for the beauty and marvelous complexity they display in action, when
participating in games. You seem to live on another planet...

George Duke wrote on Sat, Jul 12, 2008 09:15 PM UTC:
[Anyone confused, Muller is abruptly referring to my 22.August.2007 never brought up since with small error.] A larger issue is that there are over 3000 CVPage separate write-ups for games and 10,000 to 20,000 different Chess pieces in CVPage alone within the write-ups. Who is familiar with as many as 200, a mere 10% of them? As often said, anyone can invent a new CV or a new Chess piece. Have RN and BN been established to stand out from 10,000 others? By what criteria? Certainly they suffer terribly, the Centaur and Champion, for having been horrendously overused. Want a CV of one's own? Just sketch out a new Carrera array. Most variantists get to point they find Ce. and Ch. unappealing and try to avoid them in new designs. They are okay, the Carrera Centaur and Champion, I play them extensively in hundreds of Game Courier scores, no problem. There is of course the error about mating in that Comment this old thread from summer 2007. It means of course within 3x3, the small example that is sketched, not the larger boards. Within the 3x3 shown it is drawn game, as described, a very common technique in Fairy Chess Problems, used here to show the peculiar different interactions of RN and BN. Frankly, though I would say I find RN-BN rather awkward and unaesthetic, having been forced to learn their techniques for their ever-present uncreative popularity. To the contrary, probably most Grandmasters would find RN and BN considerably unlovely and reject them outright. Capablanca re-proposed them, and they institutionalized FIDE a couple years later(1920's), perhaps a connection. Credit Yasser Seirawan for having gone out on a limb, but notice that cautiously he does not introduce them to the board right away.

H. G. Muller wrote on Sun, Jul 13, 2008 07:10 AM UTC:
So (BN) is flawed because it cannot enforce mate on 3x3 now? What kind of
reasoning is that? Falcon cannot do that either. In fact, it cannot even
move on a 3x3 board. Does that mean it is even more fatally flawed?

I think it is a mistake to consider using a different array as creating a
new variant. I usually refer to such things as sub-variants. In the
WinBoard GUI, 10x8 games like Carrera, Bird, Embassy are all played as
'variant capablanca'. If not actually playing Capablanca, the user will
have to provide the opening setup (as FEN).

I guess (BN) and (RN) are so popular because their play is appeling in
practice, and they blend in well with the usual crowd of FIDE pieces.

''Fatally Flawed'' has each of 10 Demos different, all so far using
board positions. DEMONSTRATION IX: Major lack of aesthetics in
BN(Cardinal) + RN(Marshall) is being two different pieces. Out of the
ordinary Janus Chess uses two BN on 8x10.  Where are two RN on 8x10?
Practically nowhere, you don't do that, because (notwithstanding
exceptions like Janus) the pieces cannot stand on their own hindlegs. Each
dependently needs the other somehow presumptively to balance right. What other different
pieces more or less are always mated up that way in designs? Very few. (We
can think of some later you forget.) For example, Berolina Pawn is not
matched 50-50 with Orthodox Pawns (except Overby's). If Templar is any
good piece, introduce two Templars (Templar Chess), and at least do not
require its accompanying inverse, contrapositive, companion, whatever
always. Dreadful Omega Chess even implements two ''Champions'' (WAD) and
two Wizards (Ferz+Camel), based on their strengths, such as they are. If
Winther's Mastodon Chess new-old piece up to two squares is great, it
does not need supporting cast mandatorily.

In support of DEMONSTRATION IX> There is no obligation to use Ultima
Chameleon, V. R. Parton Swapper, or Rococo Cannon Pawn with some separate

Jacks & Witches. That cannot be done with RN-BN, or you get clumsy
over-strong, even more grotesque game-destroying Amazon(B+N+R). Altair two Grand Bishops, Sissa two of each, Centennial two Spearmen, Quintessential two Quintessences, Grande Acedrex two Gryphons -- each pulls itself along by their own bootstraps, unlike the derivational Centaur-Champion.

I have no idea why any variantist is remotely interested in using anymore
Carrera Centaur (BN) and Carrera Champion (RN). On a scale of 1-10 of the
major CV pieces with one at the top, RN and BN are ugly at about 8.0. I
think most designers would put them right below the middle about 5.5 or
6.0, not so low as I do. They ruin many a CV, and are about as interesting
and cumbersome as using mediaeval Alfil (2,2) leaper on a large board.
Dutch designer Freeling's Grand Chess, long referred to as great by
certain novices, gets no more mention here. Any bifurcator or ShortRange
Project piece or Betza ideal-and-practical-values compound lacking full range
tops RN and BN in beautiful play as a general rule. It would not be too hard nowadays to start to rank the best 500 CV pieces, and RN, BN and RBN have only historic interest. This thread describes
several specific flaws. Tutti-Frutti uses the three horrors together on the standard small board, Amazon, Centaur, Champion. I think Betza and Cohen are doing this more or less facetiously -- harbinger of Betza later post-2000, when he straddled important design and sarcasm.
http://www.chessvariants.org/dpieces.dir/tuttifr.html
In fact, you would be hard pressed to find two more Betza uses of RN and BN. He grew out of them. By the days of Chess Variant Page Betza stopped using them -- relatively speaking.

H. G. Muller wrote on Tue, Oct 6, 2009 07:42 PM UTC:
The (BN) is actually one of the most wonderful pieces ever designed. The
exceptional synergy between the B and N move make it unexpectedly powerful,
and this power is wielded with exquisit grace when the piece is properly
used. It creates action and excitement on the board, wherever it goes. The
only name that does it right would be 'Dancer'.

The Mad Queen is a comparatively dull and Boorish invention compared to
(BN). The (RN) piece is not so hot. It is a bit clumsy. In Chess with FIDE
Pawns, open files tend to be scarce, and orthogonal movers are severely
hindered in the middle game, the phase of the game that counts. Diagonal
moves run the show. Anyone having watched sufficiently many high-quality
games involving these pieces will attest to that.

Quite possibly (RN) would be a wonderful piece in combination with
Berolina Pawns.

Sam Trenholme wrote on Tue, Oct 6, 2009 08:09 PM UTC:
A lot of people like the Capablanca game. A 10x8 board with the RN and BN pieces is one natural extension of Chess. This is why it was proposed not long after Mad Queen Chess came out; this is why the strong player Bird endorsed a version of it in the 1800s, world champion Capablance endorsed it in the 1920s, and why the strong player Seirawan has endorsed an 8x10 version of it in the 2000s.

Betza didn't use these pieces together because his goal was to make a variant using the FIDE pieces that was as strong as the FIDE army. You can't have the RN and BN with the Queen if you want to do that. However, in CWDA, Betza added the RN to the “Remarkable Rookies” army and the BN to the “Colorbound Cobblers” army, so he obviously had no problem with the pieces, just with having too many of them on the board at once. Also, look at “Almost Chess”.

Speaking of Betza, I wonder about a Capablanca variant where the knights are different; one is a Betza Crab + Ferz; the other knight is Crab + Wazir. Instead of an Archbishop, we have a Crab + Wazir + Bishop; instead of a Marshall/Cardinal, we have a Crab + Ferz + Rook. Should be about as powerful as the Capablanca army, and allows 252,000 opening setups instead of “only” 126,000 opening setups.


George Duke wrote on Tue, Oct 6, 2009 08:11 PM UTC:
I prefer any of several dozen bifurcators to BN. There is a lot of beauty
on the chessboard down to Betza's Half-Duck and Berolina Pawn. I think I
should in fact differentiate the distinction H.G. draws. That 1-10, BN is
5.5, about average, among some CV-piece-type 500, and it is the RN, 9.5, that
draws down the average for the pair. Pritchard suggests RN to replace RB in
Intro 'ECV' but obviously on 8x8 with standard Pawns, BN is the one as good
as Queen. I wouldn't want BN on 8x10 or 10x10 to substitute for Queen. I
think the best Carrera-style outgrowth is Janus 8x10, dispensing with
Champion(RN). Obviously some few still like Centaur and Champion, but they
are average to most modern designers. [Sam will have noticed, this comment went up simultaneous as his.]

M Winther wrote on Wed, Oct 7, 2009 12:10 PM UTC:
I suppose it boils down to the strategical dimension. I, too, prefer
variants that are more strategical whereas the BN and RN pieces typically
enhance the tactical dimension. Capablanca Chess variants are not very
strategical but often result in brutal tactics in the middlegame.
Nevertheless, I have created a version which utilizes the 'relocation
method'. It implies a thorough kill of theory in Capablanca Chess. The
Capablanca piece array can in one move be rearranged by the players,
creating 144 different board positions. There is a strong Zillions
implementation of Capablanca Relocation Chess here. I don't know what
it's worth. I did it mostly to promote my relocation method.

I started this thread, among a dozen other threads, over two years ago,

is not even here yet thought sometimes mentioned. That is, they are so lame
as compounds they don't go paired as individuals but interlocked. You
can't have one without the other. Sort of like Schizophrenic Chess has
Left Schizzy and Right Schizzy.  One reasonable exception is Janus Chess,
trying paired BN not without interest. Modern designers avoid the Knight
compounds with sliders, because it ruins the regular Knight. Everybody
knows that. I lost what respect I had remaining for Seirawan when he and

each his own. When Capablanca's name begins to fade, they'll call the
things Seirawans, well-deservedly. If, incredibly unlikely, Centaur and
Champion turn out to be some next phase, too bad for the CVPage million
CVs, since 8x10 Carreras, and 10x10 by implication, have been around since
the end of the first full century of the fine small 8x8 Mad Queen, now
played out (if it wasn't already in Capa's day). Capablanca had nothing to do with either inception, did he? To
call these things Capablancas, in accepted practice, is lifting from prior
art.
