That way, each symbol still means the same thing no matter which side it's on. Or use English symbols QRBN for one color and German symbols DTLS for the other... Caïssa Britannia. British themed variant with Lions, Unicorns, Dragons, Anglican Bishops, and a royal Queen.

As I read it, Dragons have no influence whatsoever on the squares they leap. For example, a Dragon on d1, controlling the line d3-d5-d7-d9, would not stop an opposing Queen moving a6-h6, crossing at odd distance from the Dragon. "On one other note, why promote your pawns to Knights rather than Unicorns?" In order to promote to a Unicorn, you must have lost one of your starting Unicorns. Man and Beast 02: Shield Bearers. Systematic naming of divergent coprime radial pieces.[All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2013-05-22 UTCOn the prefixes: given the four "basic" (European, Warhead, Ambush, Nonchalant) patterns of capture/non-capture allowed, we have prefixes for those with zero (Ancient), four (Eurofighter), or two (all six ways) powers. Missing are those with three. Proposals: anti-European (must capture at least once): HUNGRY anti-Warhead (may not capture twice): DIETING (no second helpings!) anti-Ambush (if first is passive, second must be too): ELECTRIC ("It has to warm up... so it can kill you" of Wednesday Addams' electric chair) Anti-Nonchalant (if first is capture, second must be too: ADDICTED (gotta keep killin'...) Puzzle Shatranj. Shatranj on a 15 puzzle. (8x8, Cells: 60) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2009-12-21 UTCYou only have 15 pieces, so 'at-least-one' implies 'exactly-one.' On the commentary, a piece with eight bindings is thrice colorbound, not four times (which would mean full coverage requires sixteen). At the fourth order, it is switching (as the Ferz is at the second order and the Knight at the first). Alternate Promotion Chess. Pieces promoted at one end of the board are promoted further at the other.

(8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2009-08-29 UTCIsn't the running-leaf by definition stronger than a queen, since the queen is a subset of it? (That is, if the 'degenerate' planar move in which one side of the plane is 1 is an allowable move.) And I can tell that the young-lion is not allowed to return to its original square (a limitation not shared by the Japanese lion), but there is one slight unclear point: is it allowed to make double captures? Shogi 59. Shogi on half of a 9x12 board.

I don't think the two players ever interact! (Think you may have meant 9x13, which puts both players on the same color and gives you 59 cells of that color...) Checker-capture Chess. Pieces can capture as in checkers game. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2008-12-31 UTCLooking at rules 2 and 3 together, I assume this is the Russian-style multi-jump rule (no stopping if the piece has another jump, but you may take it in a direction that has fewer)? Faster and Faster Chess. Pieces move one square, then continue two, then continue three... (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2008-10-31 UTCI think the 'and then three' comment is redundant for the Knight, since six Knight-leaps in the same direction would require a board of 13 squares in at least one dimension. Hmmm... using such a piece in a variant with a larger board, could the Rook and Bishop go 'and then four,' or is three the speed limit? Come to think of it, a piece like this with a 'speed limit' of 2 might be interesting-- the Rookwise piece would be color-changing, while the Bishopwise one would remain colorbound, but switch Alfil-bindings... hmm, I just reinvented the Panda and the Bear. Conclave Ecumenical Chess. Large variant with wide variety of Rook and Bishop compounds.

Missing description (10x10, Cells: 100) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2008-07-11 UTCI believe that by 'attack' he means 'capture.' Always tricky writing in a non-native language... Hafts. A denser Draughts, but with pieces only capturing those bound to the opposite colour. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-06-14 UTCThink of it as two games of checkers played at once, one on light squares and one on dark. (Thus, the starting setup is 24 pieces, solidly occupying the back three ranks.) Then change the pieces' capturing move to orthogonal instead of diagonal (straight ahead only for plain men, all four directions for crowned men)--so a piece in one game actually captures pieces from the other. Sultan's Elephant Chess. Pieces can group together in fours to form giant pieces.[All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-05-18 UTCThe Waffle is for some strange reason linked to the Gold General. It actually appears in Chu Shogi under the name Phoenix. Recognized Chess Variant: Wildebeest Chess. Now a Recognized Chess Variant![All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-04-03 UTCKeeping in mind, however, that stalemate is a win in Wildebeest Chess, can a Wildebeest or two Camels (or for that matter two Knights, or Knight+Camel) defeat a lone king with that rule in place? Haynie's Primary Chess. On 6 by 6 board without knights. (6x6, Cells: 36) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-04-03 UTCYou could easily play with knights instead of bishops--that would be Los Alamos Chess plus castling. The FIDE Laws Of Chess. Missing description[All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-03-21 UTCIf the scoresheet provided is electronic, then that's what the players use. As for personal electronic scoresheets, you'd need a way to prove that they can't also be used as playing aids, but that done, the arbiter would be within his rights to declare that an accommodation for a handicap, I would think. Rules of Chess FAQ. Frequently asked chess questions.[All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-03-10 UTC'Baring the king' (as it is traditionally called) does not end the game in standard Western chess--the player with the lone king cannot actually win (since there's no way to give mate with just a king), but can still lose or draw. If both kings are bared, of course, the game is a draw. Invader Zim Chess. Chess based on the show, Invader Zim.

The British officially abandoned the 'British system' in 1974, although there are those who still remember/use it. The only unambiguous way of saying it is '100 million million' ::) I'm a Wazir, Get Me Out of Here. A variant in which pieces disappear if left too long in the wrong place. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2006-01-19 UTCActually, on a plain 8-by-8 board, the Wazir with the opposition can force victory by simply closing in on each move and eventually cornering its foe. This may not be true on the board at hand, though; there is a possibility that the defender could thwart that plan by making proper use of the quicksand center region. Transmitter Chess. Drone pieces have no movement until activated by one of three friendly Transmitters. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2005-11-28 UTCYou also failed to allow Wazir Kings to move in any of the actions. Presumably they should move instead of a pawn/drone/engineer? EEEEEEEEEEEEEEEEEEEEEEEX! Chess. A game designed to be as different to chess as possible while still being the same as chess. (1x72, Cells: 72) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2005-11-03 UTCTwo other notes. First, ShoppingCarts should be able to promote on the square where a Rex began, as well as those you list. Second, you only need 71 squares--the last Fire is irrelevant to the play. Capablanca's chess. An enlarged chess variant, proposed by Capablanca. (10x8, Cells: 80) (Recognized!)[All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2005-09-28 UTC'Uncovered pawns are not that problematic because any situation will have to be set up randomly very short before a game starts. Looking at the Shogi game there are indeed three uncovered pawns in the beginning and the game still does exist today. Capablanca's chess is somehow different to that because of the huge number of possible starting arrays viewing all shuffled combinations.' I think the problem is more a matter of the piece set and shape of the board. Even if a pawn is undefended in a Fischerandom setup, it can't be attacked instantly, unless it's an a/b/g/h pawn and the piece on its diagonal is a bishop or queen. But an archbishop or chancellor has a pretty good chance of being able to make an instant attack on that pawn by jumping over its own pawn row (as the chancellor can indeed do to the i-pawn in Capablanca's setup), and the diagonal discovered attack can affect 80% of the pawns instead of half. Upon further review, we're discussing opposite ends of the issue. The points I just made are why the no-undefended-pawn rule is desirable; the large number of positions is what makes it practical (i. e. you still have a huge pool of positions to choose from). Proximity Chess. Players must move pieces nearest to the arrival square of the last piece moved. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2005-05-04 UTCHow is 'distance' defined in this context? Number of King-steps, number of Wazir-steps, Cartesian distance? Bario. Pieces are undefined until they move. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]J Andrew Lipscomb wrote on 2005-03-28 UTCMy suggestion for castling would be as follows: the corner disk must not have moved, and must have the potential to be a rook (castling will reveal it to be a rook). Pawn promotion is also potentially awkward. I propose a variant of the Grand Chess rule (a pawn may not move to the last if the owner already has seven quantum pieces, revealed or unrevealed, but may still give check). I also propose that pawns promote revealed. I would also note that this variant can be combined with many others, such as Capablanca/GrandChess, Different Armies, or even Jetan (to practice the mechanics, you could also go the other way and apply it to Los Alamos Chess). Cross Chess. Game played on a cross-shaped board.
