This game starts on a 15x15 board where each side has 15 pawns, 4 rooks, 4 knights, 4 bishops, 2 queens, and a king (the pieces will start on the 2nd, 3rd, 13th, and 14th rows). Starting from move 20, the board shrinks such that the outermost edges of the board disappear. Any pieces in this area get removed from the game. If one player's king gets removed, the player loses. If this happens to both players, the game ends in a draw. The 15x15 board will turn into a 13x13 board on move 20 and a 11x11 board on move 40. If the game didn't end already, the board will not shrink further after it turns into a 5x5 board. All usual rules of chess apply in this game.

i wanna see whats my chaturaji position... I am sure lots of people want the leaderboard back, when will it be?

GrandChess is the ultimate upgrading of Chess in 3 dimensions, with the same rules as the 2-dimensional chess game but much greater degree of complexity. This is indeed a game fit for the GrandMasters' minds. There are 512 cubic boxes instead of 64 squares. 128 grand-pieces for each player instead of the 16 pieces. The GrandChess framework contains 24 planes that are equivalent to a chessboard. Each grand-piece is positioned on 3 such planes; you can move it on any of the three chessboards; so playing a GrandChess game is very much similar to playing a simul on 24 chessboards against a single opponent. Huge numbers of opportunities, positions and variants. An immense space opening up for larger openings theory. In Chess you can reach 400 different positions after White and Black's first move. In GrandChess the positions are 40,000 only after first move. Some people say Chess is going to be "solved". I.e. one day a chess engine, a learning machine or quantum computer will tell us that the starting position is a win (or a draw) whatever we play. Playing chess will then loose any interest. It'll only be a matter of memorizing the right sequence. This is my gift for free to all Chess enthusiasts. So if Chess will ever be solved you can go on playing GrandChess while the engines are going to have indeed a hard time solving this one too. Here are some explanatory videos, but the rules are the same as Chess: https://www.youtube.com/channel/UCOeIXNTxzW_IC1T1Mlxolew/videos Only exception: castling is made in two moves (pre-castling and castling), due to the three dimensions. Waiting for good programmers who can make it onto online platforms and maybe we will play it on Chess.com too.

So this is a Rhombicuboctahedron: I'm imagining something like 64 smaller square tiles within the "square face" and the triangle faces are unused (to keep things simple - but of course you can add triangle tiles within if you wanted to). Each army (up to 18 players, suggested for equal proportional distance to other players: 2, 3, 4, 6, 8, 12), inhabits one of the shapes square faces in a formation suitable for the amount of players playing. I haven't thought of how the armies should be positioned or how things like pawn promotion would work but this is the basis of the idea and you can make variations out of it as well. Mostly I was trying to go for something that would look like Chess on a Globe but without the annoying super thin tiles up at the North and South Poles. I came up with this. Feel free to come up with set up suggestions. Here's one I'll make that an army could have on one face:

So, this is kind of an interesting one. I suspect it's related to the rating redo that happened for the leaderboards. I think I somehow started playing games that effected the old rating stat instead of my new one. As you can see here, between playing DrAtom102 and DiamondDan137 it looks like I somehow lost 27 points without playing any games. After playing DrAtom102, I checked my rating on the leaderboards and it still said 2722 even though during the games my rating said I was higher than that. I figured it might just be that the leaderboard script only runs every so often and it was just taking a while to update. But when I went to play DiamondDan137 I noticed my rating had apparently dropped back down 27 points. I think what actually happened is that I somehow played games that effected the old ratings that were being used before the leaderboard feature became available. I think this because clicking on my name in my games with DrAtom102 shows the atomic blitz rating breakdown thing, like it used to before the leaderboards, while clicking on my name in my games with DiamondDan137 does not. I have one theory as to how this could have happened. Maybe. It involves the fact that players can't accept challenges if the ratings are too different (I think this is the reason at least) but they can accept rematches. If you try to challenge them everything will look normal, but then nothing will happen regardless of whether they click accept or decline. I asked keiranmiddlebrook in chat if he wanted to play a few games and he said sure. Since we couldn't get a game by challenging each other we went back to the last game we'd played and clicked the rematch button which is available when both players are around. This is a very nice work around to have available since it allows me to get games with people I've played before if they want to play, which can be hard due to my rating being so high lol. This game was from before the rating change that came with the leaderboards and I think it lead to the system using the old ratings instead of the new ones somehow. I didn't notice it at the time, but looking back there was a rating jump there as well. Now why did this effect my games with DrAtom102? IDK. He challenged me and I clicked accept, but nothing happened, as is normal with large rating gaps. To show him that it wasn't because I didn't want to play him, but rather because the accept button didn't work, I sent a challenge to him, and he clicked accept which as expected didn't work. But then he sent another challenge to me, and this time the accept button did work. I have no idea why it worked this time, but given that it happened right after my games with keiranmiddlebrook where I do have an explanation for why it might have used the old rating system, I suspect the fact that my old rating was used for these games is related. TL;DR A bug occurred which was likely related to another oddity that I and other players had been using to get games when the challenge option wouldn't work for whatever reason. Lots of strangeness involved.

Each piece can make two clones of itself, taking a whole turn. Clones must be placed on the adjacent squares (on the same vertical, horizontal or diagonal. The only exception is Knight, but more on this later, as the explanation would probably require to see this on a real board*) . If the adjacent squares are occupied, the move is considered illegal. Then player can choose which cloned piece he considers as "real" (let's call other clones "fakes"). If the "fake" piece gets attacked, it disappears by the next move . Similarly, if the "fake" King gets checked it also disappears. The "real" King might ignore checks, but if it gets captured, the side that captured King, wins. Each piece can make clones only once per the game. Pawns can't make clones. * about Knights. Knight clones must be placed on the free squares that Knight can move to: To avoid too much compications, clones of a Knight must be placed on the squares of the "same direction": if a Knight on g1 decides to place a clone on f3, the second clone must be placed on e5 . Second example: Black is threatening mate with the Bishop+Queen battery, but White replies with Nd2@c4@b6+ and wins Black's Queen. This makes a Knight a long-range, and probably one of the most dangerous piece ever (after the Queen, probably). UPD. Similarly, Bishops, can make only make clones along the same diagonals they move, the same rule applies to Rooks (they only make clones along the vertical or horizontal they move). UPD2. Fake clones of the piece should be indistinguishable from the real piece for the opponent (at the same time, player should be able to distinguish fake clones of own pieces from the real piece).

Well yes this is a really crazy chess variant that I invented to create my fairy chess problems. This is somewhat reminiscent of metamorphic chess, but nothing more. The rules are simple. Each piece automatically transforms into a different piece every time it moves. Pawns transform into Knights Knights transform into Bishops Bishops transform into Rooks Rooks transform into Queens Queens transform into Pawns (except for the first and eighth rank where Queens always remain Queens for both White and Black) King remains King There is no promotion for pawns on the last rank, no en passant, no castling. Here is a simple chess problem in this variation of chess. White to move and mate in 4 1. Ng3=B+ Kc8 (not 1...Kc6 2. b4=N#) 2. Bc8=R+ Kc7 3. Rb6=Q+ Kc8 And now 4. Qb8# Remember that Queens on the last rank remain Queens! So what do you guys think?

I have a very interesting idea. This is a chess with a flag. The idea is that each opponent has a flag that must be captured from the opponent and brought to base. Own figures can also carry their flag to protect it. The winner is the one who brings the foreign flag to his base (1 line for white, 8 for black). This game has the concept of a drop.That is, the flag is set on the first line (for white, 8 for black) on any square. The flag can only be displayed after any figure on the extreme horizontal has left its place. The checkmate also wins. How do you like the idea? Share your feelings.

I have an idea. My new version of chess with archers and towers. This is a classic 8 by 8 chess game, but with two additional pieces in hand (on each side), white has one tower and an archer, and black has one tower and an archer. The archer moves like a bishop + king, a tower like a rook + king. In this version, the concept of a drop is present, that is, in this game, the pieces that are in the hand are exposed in the same way as in seirawan chess.

LoOkS cOoL isNt iT?

I would like to see what my overall score is against some players. Is this possible?

Errrrr what is that on the queen and y is it upside down???

What do you think about Variant Tournament like these, 5 | 3D 4 Player Chess Tournament 5 | 5 XXL Chess Tournament 2 Min Atomic Tournament Although we need another rating system about this, but it will be pretty good isn't it

One bug has already been mentioned in other threads i.e. : when a player 'bares' the opposing King and owns a Knight the game is declared drawn by Insufficient Pieces rather than being declared won by Bare King rule. The other one is a bit more complex to explain and detect. Sometimes the Bare King rule doesn't apply immediately. The underdog should have only ONE move for trying to draw, but in some cases s/he gets the possibility to make several moves before the system recognizing his/her loss.

in the custom variant passing + fog of war, there is a bug similiar to the one we had with castling, when fog of war first came out: when you pass intstead of moving your opponent can hear this as a different sound as the normal move. Because they managed to fix the castling sound problem, this shouldn't be so hard to fix either

I think Crazyhouse can be played with 4 players.

1. No Trade A piece cannot capture the same piece(except for pawns). --> White Queen cannot capture Black Queen. So they cannot trade their pieces. 2. Winmate A player whose king is stalemated wins the game In this position, Black wins the game.

As many of you know, Chaturaji Hyper Fiesta is the most popular 4-Player Variant on the 4-Player Chess server and has been for a long while. Chaturaji has also been added to the variants server, but double-check gives 1 point on the variants server, and triple-check gives 5 points. On the 4PC server, double-check gives 5 points and triple-check gives 20 points; as one of the strongest chaturaji players, I think I speak for almost everyone when I say that reducing double-check makes the game more boring, less interesting, and less strategic. Can someone change the double-check/triple-check points back? If it makes some other variant imbalanced, then can someone just set double-check/triple-check points differently for the other variants in question?

Simple: It's called KNIGHTMATE. The king moves like a knight and the knight moves like a king.
