This is a great concept for an army! I like how the Vouivre encourages tactical play with its forking capabilities and ability to do nasty smothered mates, while the Geese are more focused on strategic pawn play in the endgame; similar to how the tactical Knights and the strategic Rooks provide a variety of viable playstyles in the Fabulous FIDEs.

In your opening line, 2.Vg5 doesn't work because of Qxg5.

PS: If you're willing to upload this army to ChessCraft, I'd be happy to playtest them alongside my own Starbound Sliders.

Edit: Upon closer inspection, this army is actually very weak.

  • Ouroboros: 2x5pts Although the Ouroboros is about Rook strength, it's the only one that's as strong as its claimed to be.
  • Roc: 2x3pts+0.5pts colorbound pair bonus The Roc is colorbound and has limited range, making it weak and finnicky even by minor piece standards. Complicated maneuvres are less viable when the board is full of pawns, which further highlights the Roc's difficulty in movement. It is definitely not as strong as a Rook, though its ability to reach 12 squares means it may be slightly stronger than a Knight.
  • Flying Goose: 2x1.5pts The Flying Goose has very little value, and also gives the Beautiful Beasts the very annoying trait that they can't castle without moving one of the three Pawns that will be in front of the King (unless they castle queenside and mave the a pawn). Granted, the Flying Goose is little more than a slightly stronger pawn anyway, but still.
  • Vouvire: 9pts The Vouvire is reasonably strong for a Queen equivalent and it's great for tactical play, the problem is that there's nothing to play tactically against. Knights are fun to use because they're the weakest piece in the army (so when they fork something, you're in business!) while the Vouvire is the strongest piece so it can't fork anything that's protected. Also, it can't go to any of the 8 adjacent squares, which makes maneuvering on a crowded board surprisingly difficult.
  • Total: 28.5pts CwDA armies typically range from 31.5 (Fabulous FIDEs) to 33.5 (Nutty Knights) with more complicated armies needing more value.

This is an interesting and logical approach to tackling how to have a double-move variant addresses pesky rules like check and en passant.  They always require special-case rules to address, and how it is addressed here "feels" right to me.  Marseillais Chess handles the check thing fine, but falls down on how en passant is handled.  You seem to have neatly solved that, too.  I also like how you are limited to one capture per move and cannot move the same piece twice.  This also helps to preserve the strategical similarity to orthodox chess. I guess Marseillais is more of a "let's make double moves and we'll end up with an interesting but totally different game."  Originally, it wasn't even "balanced" (white started with two moves.)  This is an ambitious attempt to add the property of double moves games being "balanced" while changing as little else about the game as possible.

Extra Move Chess also provides similar benefits.  You can make a second move, but don't have to, as long as it doesn't capture or move a piece that just moved.  If you make a second move, it can be a two-space pawn move (which a first move can't, except for white's first move of the game.)  This also neatly solves check and en passant.

I'd like to add this to ChessV.  I think it's doable but I need to think some things through.  The thing I see that most concerns me is this:

Each position created by a two move turn is included in the count toward a draw by threefold repetition, or toward a draw by the Fifty move rule (or the Seventy-five move rule)

If I understand this, it would be difficult to implement and doesn't make a lot of sense to me.  Are you saying that any move in a single move turn or responsive move turn should not count towards the 50-move rule, nor should they be counted toward any potential repetition?

This seems like a nice variant. I especially like the 32221111Q movement of the pawns. The falcons/bison are also fun to play with, their long leaps make for nice tactics.

Pretty much the only thing I'd change is that castling leaves the King too close to the middle. Instead, I would make it so that castling results in the King and the Rook swapping places (White king can go to b1 or i1, black king can go to b10 or i10; rook always goes to the f file) as this gets the King 1 space away from the corner. This would also fix one of the gripes I have with regular chess: queenside castling is usually terrible. Opposite side castling often leads to fun games, so making it happen more often seems like it would be desirable. Also, it would allow players to castle by moving the Rook first, as the ambiguity between O-O and Rg1 is removed.

I came on this page by accident. After so many years, the name of this game is still wrong. It is Doushouqi, not Shou Dou Qi at all. And the comment about jaguar for leopard is absolutely right. The solution to avoid a L is to call this piece a Panther, panther or leopard is the same animal.

I've only played this once, but it feels right somehow. The hexagonal board, oriented horizontally like this, gives a distinct chess experience that square boards generally lack. It feels more natural than square shogi to me.

I like the Stars, they present a naturally digestible identity, in keeping with the elementary makeup of Classical pieces. I would have invented a more relatable name for them, perhaps 'Sheriffs' or, something you know, that has a real life character, but nevertheless I praise you for their design.

Nice work.

A very well thought and pleasing out blend of a Capablanca's Chess and Shogi. I am curious about the rule against having identical promoted pieces other than promoted Pawns. I consider it a small wart on a otherwise perfect design.

Eric Silverman wrote on 2021-07-07 UTCExcellent ★★★★★

I have played this game extensively in the Ai Ai software package since adding it, and I feel it may be the best iteration so far of Jean-Louis Cazaux's series of 12x12 variants. The piece density and variety generate very interesting interactions on the board. The various Pawn- and Pawn-like pieces in the 3rd/4th ranks create a nice sense of progression, leading the board to gradually open up and allow more powerful pieces to enter the fray.

In a sense, the game reminds me slightly of a Chess equivalent to Dai Dai Shogi, which has a long opening phase that gradually expands into a delightfully complex middlegame. As a fanatic for large Shogi I consider this a plus :)

In any case, I highly recommend this game for fans of larger variants. In the future I hope Maasai might generate some similar developments of Gigachess and Terachess as well. I have experimented a bit myself with adding the two ranks of mixed Pawns to those games and the results were quite enjoyable.

Eric Silverman wrote on 2021-07-02 UTCExcellent ★★★★★

Having implemented this variant in Ai Ai and having played it a bunch of times, I really enjoy this game. Being a large Shogi fanatic, the higher piece density of Yangsi doesn't bother me in the slightest :)

For me this game is an improvement on something like Sac Chess, as the pieces in Yangsi are more interesting to use. In fact I was inspired by this game to make what I called 'Heavy Shako', an extension of Shako that fills in all the gaps in the back rank with other pieces used in the larger variants by Jean-Louis Cazaux. The original concept was much improved by some excellent advice from Jean-Louis, and the resulting game has been a lot of fun.

I'd enjoy seeing an extension of Yangsi to 12x12 with a high-density setup, too.

I really like these experiments with reducing the size of Tenjiku Shogi with H. G. Muller's Nutty Shogi and Dr Eric Silverman's Makyou Shogi.

Thanks for mentioning Makyou Shogi, I'm glad someone noticed it :) It's a work-in-progress still, but I do enjoy it as a smaller, rapid-fire introduction to Tenjiku Shogi.

I have never played Tenjiku.

Give it a try before you go for even weaker pieces :) The original, full-power Demon is still usable even on 12x12. Personally I'd rather see this game with a stronger Demon than an even weaker one.

Hence my rating for this game -- I love the use of the Microshogi promotion rule, and the overall goal of a less brutal Tenjiku/Nutty Shogi is an admirable one. My one issue is that the Demon is so weak in the Suzumu family of games that the flavour of Tenjiku is mostly absent; Tenjiku is almost defined by the terrifying presence of the Demon, much like the Lion in Chu Shogi. If the Demon were powered up to something in between the original and this one, I think this game would be even more interesting.

I really like these experiments with reducing the size of Tenjiku Shogi with H. G. Muller's Nutty Shogi and Dr Eric Silverman's Makyou Shogi.

What I like about this version is that the powers of the super pieces are more limited and the weaker pieces have been boosted. The board is also about the right size and the prmotion rule is intriguing.

The original powers of the Fire Demon and Generals were such that they could cause devastation and that any mistakes could be punished very quickly.

In fact I would like to see a version with even more limited pieces, where generals can only leap one piece and area movers are limited to two king moves.

I have never played Tenjiku. Me and a friend spent an hour setting up the game for the first time in a cafe and had to pack it away, just admiring the pieces all set up. I'll metion this game to him and see what he thinks of it.

A couple of things I am curious about is the lack of symmetry with the Phoenix and Kirin which looks a bit odd, and if it would be a good idea to have a Dog on g5 and g9 to prevent the early trading of Rook Generals.

Also a couple of issues with the page: in the piece table it currently it has a Rook General promote to a Free Eagle, and the King promotes to a Vice General in the interactive diagram.

The page is really well thought through and presented and must have taken a lot of work, well done.

I wish this game were more popular. It seems like an excellent design. The piece selection seems strange at first but after thinking about it I can see the beauty of it.

I imagine the aanca could have originated as an enhanced ferz, to go with the bigger board. Then the knights could have become unicorns by gaining a diagonal slide after their leap to complement the aanca. The crocodile is a fairly obvious addition. The giraffe and Lion both make knight-like leaps, suitable for the large board, and the Lion includes and extra 3,0 leap which removes it's color binding and forms a nice looking pattern.

The result of all that is eight pieces with a nice range of power and an aesthetically consistent set of moves. There are all of the 2,1 3,1 and 3,2 leaping moves, the rook and bishop moves, and bent rook and bishop moves (unicorn and aanca). The leaping pieces are differentiated in power by some of them having additional movements, but they don't ever feel like arbitrary combinations.

The initial setup is also elegant. The Pawns start as far apart as they do on the 8x8 board, and the pieces are all on the back rank. The promotion rule fits well with this setup and is another great innovation.

I think the main weak points, if there are any, would be the pawns and the king's leap. It seems unlikely that the king would benefit much from a 2 square leap on such a big board with so much empty space; and perhaps modern pawns would be better. But overall this variant appears to be carefully designed.

You only need to checkmate/fork one King. In the standard-Rules version. Game play tends to be the same length as regular-chess.

Its one of the least complicated 3D-Games. Simply set-up 2-sets of chess-men.

The hardest part to explain is why its frowned upon to go on side-ways diagonals (in 3D) or that knights should not go in L-shapes without advancing or retreating from the opponent. I say frowned-upon, because of course you can change to non-standard rules. But you may find the game much longer, and knights to be as powerful as queens. Stalemates to be more attainable...

Sam T wrote on 2021-03-15 UTCExcellent ★★★★★

I have, as per Freeling’s comment, made a number of variants to Congo to address the issues brought up:

  • To address the fact Congo looks drawish, I have adopted the “Ko Rule” in my variant: Someone who repeats a previous position in a game loses. This eliminates draws.
  • To address the issue with river drownings making attacks harder, I have made the A, B, F, and G files of the rivers have “islands”: While the crocodile can move like normal on these squares, other pieces will not drown.
  • I have made the pawns stronger: A pawn can not retreat until it is promoted on the 7th rank; on the other hand, pawns across the river can now move and capture sideways. A promoted pawn is more powerful: It can move or capture to any space one or two squares away (like Chess, a promoted pawn should win unless it can be recaptured quickly)
  • I have made the elephants able to move forward like a Shogi Lance. They can also only move backwards one square.
  • I have changed the opening setup from GMELECZ to ZCELECZ, removing the Monkey and Giraffe, and having a second Zebra (Knight) and Crocodile. This way, the game can be played with an ordinary chess board and pieces.

In my Zillions-vs-Zillions testing, the games are never draws, and Black wins more often once we give Zillions 30 or more seconds to think through a move.

My changes can be seen here: https://github.com/samboy/ChessVariantResearch

Look in the folder “Congo”. Full rules for this variant, along with multiple possible opening setups, is here:

https://github.com/samboy/ChessVariantResearch/blob/master/Congo/EBW-1.md

Out of respect for the copyright included with the Zillions implementation of Congo, I am not distributing a modified version of the Congo zrf. Instead, I am distributing the original version, along with a Linux/Cygwin script to change Congo to have another .zrf with the modified rules. I have also made from scratch board artwork representing the new river with islands.

Good to see Hanten Shogi and its little brother revived! Looking forward to playing on Game Courier sometime :)

If I may make a suggestion, I remember in the previous version the switchback pieces had blue rather than red on the promoted side, which I thought was visually helpful. Any chance of that coming back?

Thinking ahead, perhaps there's an opportunity for an even wilder follow-up to Hanten Shogi -- a large Shogi with Kyoto-Shogi-style switchbacks after every move, including non-captures :)

I'm pleased to see this game! One correction : it is a trigonal, not hexaxonal, chess variant. The cells are triangles, not hexagons.

That said, I think this is an excellent contribution to the much under-explored trigonal tiling. Apart from a couple of games contributed by Graeme Neatham and Christian Freeling, along with a couple of my own, I think this is a little-used tiling which has lots of interesting possibilities for play.

This is a very good game. Everything fits together well. The random setup provides variety without being completely chaotic. The brouhaha squares are a great way to add more pieces without making the board so big it feels empty. The promotion rule encourages more variety in promotion, which is something I look for particularly; and I like the auxiliary pieces used here. The Mameluk especially is fun.

I think I might slightly prefer the Modern Apothecary game, for it's Dragon and Griffin, which to me are more interesting than the Chancellor and Archbishop, but I like the Siege Elephant and Mameluk as auxiliaries, so it's hard to choose one game over the other. I don't know if I'd agree with the statement that the Joker can't defend well. It seems to me that it's ability to mimic an attacker's move makes it particularly good at defending and more difficult to use aggressively. I'm not great at chess (in any form), though, so I could be wrong about that.

I'm interested to see what the next games in this series will be like!
