Normally in bare piece rule, if the last non royal piece of one player is captured, and the royal piece can't recapture the game ends before the player with the bare royal piece can move. https://www.chess.com/variants/custom/game/28371201/2/1 For instance, in this example after I captured the black rook, which was blacks last piece, the game ended, and I won, before black could move because black couldn't take back. https://www.chess.com/variants/custom/game/28371445 In this example however, when I captured the black rook the game ended in a draw by stalemate, even though the black king was bare after I captured the rook. Being in stalemate though necessarily implies that the bare king or royal piece can't recapture, and so I think if the king or royal piece is bared at the same time as stalemate the game should just end in a win for the player to bare the enemy king regardless of what stalemate is set to. I found that for other win conditions that when a win condition happens at the same time as stalemate, even if stalemate is set to be a draw the player who met the win condition still wins https://www.chess.com/variants/custom/game/28371630 In this example of KOTH, for instance when I put my king in the center, even though black was not in check, couldn't move, and I had stalemate set to be a draw, because I had just met a win condition, and so it didn't matter that black was in stalemate with stalemate set to a draw. https://www.chess.com/variants/custom/game/28371822/0/1 And in this example of capture the king, with 1 check turned on, and stalemate set to a draw, when I checked the enemy king once, I won even though black was technically in stalemate, because I had just met a win condition, and so it didn't matter that black wouldn't be able to move even without 1 check on.

Please let me confirm that the game I am about to play when having clicked on one from the lobby is the one I actually intended to pick. It can change at any time and I end up in a game I didn't choose to play. I also once clicked on an atomic game but got a giveaway game before I'd noticed and already played 1 Nf3 which is the normal start move for Atomic but a losing move in Giveaway. It might work if the interfaces didn't move the boxes around in real time, but first greyed them for a period to make them unclickable before putting a new one in its place. 5 seconds greyed out before a new one appears would stop the race-condition of what I click in that location not being the game I thought I had chosen. Today I got a 3+0 3-check game and I just can't play very fast time controls I need some time to think on my moves. Got into a very poor position very quickly by blitzing opening moves, which I just don't enjoy. I hardly play any 3-check so it's not surprising I'm not that familiar with the openings.

A couple of days ago Variants got an update with more modes than before. They added: Gothic Chess, Chaturaji, Bells and Whistles, Atomic Giveaway, Giveaway in the fog, Atomic fog, Atomic give away hill, XXL chess, Petrified, AND 4PC fog of war. Vote including the old variants (Fog of war, atomic, horde, giveaway, KOTH, ETC. and also including the new (Gothic chess, petrified, chaturaji, XXL chess, 4PC FOW, ETC. Start! My favorite since the begining has been FOW (Fog Of War) What's yours!?

I do not know if there is a place I put my ideas for a variant, so I put them here. My idea- capture the flag. Rules: your goal is to bring your, king, to the center of four squares (like KOTH.), but the game doesn't end when you get there. You must bring the king back to its original back rank with the flag captured to win. There is only one flag, once it is captured the other person cant get it. If after 20 moves the flag has not been returned to the back rank, then the flag is put back in the center up, making it anybody's game again the setup position is the same as normal chess, but the center four squares are always lit up by a color checkmate rules apply, there is no capturing the king to take the flag away. You must stall the 25 moves king is the only piece that can capture the flag Setup setup as a normal board, but all four center squares are light up until the flag has been captured. so like this: and it is light up until one of the kings has moved to that square, than the king will be holding a flag indicating that it has the flag. (not great at photo editing so I couldn't make a design) thoughts?

This idea is a little crazy, but I think it could be really fun if you could code it. There would be FFA Crazyhouse and Teams Bughouse. For FFA Crazyhouse, it would be like normal Crazyhouse on a 4P board. For example, Red captures Green’s knight, and Red can now place that knight wherever he wants. For Teams Bughouse, if Red captures Green’s knight, then YELLOW can place that knight wherever he wants. Is this doable? Does it sound like a good idea?

standard chess, but if you lose every piece but your king you win. essentially giveaway chess but with checkmate and no compulsory capture.

I saw in this discussion on how to get computers to recognize dead draw positions someone propose having the computer use brute force to search for helpmates with the idea that if the position is truly a dead draw then no matter how many move sequence possibilities a computer searches, it will not be able to find any resulting in checkmate, but if the position is not a dead draw then if the computer checks enough random sequences of moves then it should be almost guaranteed to find a helpmate sequence. I notice that the material counts, in which the game is over on this site seem to be ones, in which in regular chess there can be no 2 move checkmate combinations. For instance KNvsKB cannot have any 2 move forced mate combinations in regular chess, and so the game ends if it reaches such a position, but KNNvsKB can have 2 move forced mate combinations as when the king can't move but is not in check, the bishop can still move. Based on this I was thinking that an alternative to having the computer check for sufficient material would be to have the computer first check whether one player can checkmate on the next move, and then, if there is no mate on the next move, use brute force to check whether there are sequences of moves that can result in 2 move forced checkmate combinations. If after looking through a large search tree the computer cannot find any 2 move forced checkmate combinations then, the computer would declare the game over and give the same number of points to the remaining players as it would for insufficient material. If the computer finds sequences of moves that would result in 2 move forced checkmate combinations then it would allow the game to continue. I think this could be a good way to get the computer to detect positions, in which no player can force a mate in more than 1 move without having to individually program each situation into the computer.

Gigachess 2 how to play: https://www.chessvariants.com/rules/gigachess-ii

Right now for stalemate, in the case of 2 players there is the option for the stalemated to receive the points, the opponent to receive the points, or for both players to share the points, but in the case of more than 2 players there is only the option for either the stalemated player to receive the points or for the remaining players, including the stalemated player to receive the points. This means that in order for only the opponent to receive the points in the 2 player stage the game must start as a 2 player game instead of reducing to 2 players from a game that starts with more than 2 players. I think that for games with more than 2 players there should be the option for only the remaining opponents to receive the points, with the stalemated player receiving no points.

Chess... with a deck of cards??? - How to play. The rules are the same as regular chess, except for these changes. For a refresher of those rules, check out this video. Lay out the board and set it up as a regular chess game. Shuffle the deck and put it next to the board. Take 5 cards from the deck to your hand (and tell the opponent to do the same thing), then play as normal. You must move at least one piece to end your turn. When playing, you can play your card(s) instead of making a normal move. There are lots of card types in the game, and here are some of them: March on!: In your turn, you can move 2 pawns at the same turn or 1 pawn twice. [Last: 1 turn] As fast as a ninja: In your turn, you can move 1 piece (or pawn) twice. [Last: 1 turn] Double attack: In your turn, you can move 2 pieces (2 pieces - 0 pawns; 1 piece - 1 pawn; 0 pieces - 2 pawns) at the same turn. [Last: 1 turn] Allahu Akbar!: When you capture a piece, the captured piece "exploded" (like Atomic chess). [Last: 1 turn] Sniper: In your turn, you can capture a piece without moving. [Last: 1 turn] Bomb thrower: Work as a combination of Allahu Akbar! and Sniper. [Last: 1 turn] Res-pawn: In your turn, put a pawn from the opponent's piece-capture zone (where his/her put your captured piece) back to the board, and end your turn. [Last: 1 turn] Pawn killer: In your turn, capture an opponent's pawn and end your turn. [Last: 1 turn] Teleporter: In your turn, move one piece to any empty square on the board. [Last: 1 turn] Advance forward: In your turn, your pawn can move 1 more square straight forward. [Last: 1 turn] Amazon warrior: In your turn, your queen can move as an Amazon (combination of Queen and Knight). [Last: 1 turn] Black hole: In your turn, every piece on the inner-centre squares will be removed from the board. [Last: 1 turn] Block!: In your opponent's turn, block every effect (from the opponent's cards). [Last: 1 turn] No woman in war: In your opponent's turn, the queen can only move 1 square diagonally. [Last: 1 turn] Demote to animals: In your opponent's turn, the bishop can only move 2 squares diagonally (as the Elephant). [Last: 1 turn] Welcome to Japan!: In your opponent's turn, the knight can only move 2 squares vertically AND 1 square horizontally (as the Katsura Horse ~ Shogi Horse). [Last: 1 turn] Ice age: In your opponent's turn, the piece can only move to the furthest square in the selected direction. [Last: 1 turn] The rules of physic: After you play this card, the rooks can't even move and capture anymore. [Last: forever, can't be blocked] Model mothers for the world: After you play this card, the queen can only move and capture 1 square orthogonally (vertically or horizontally) OR jump 2 squares diagonally (as a Chu Shogi Phoenix). [Last: forever, can't be blocked] Blank: Unaffected. In the 1st turn, if you draw 5 Blank, you win immediately. [Last: 1 turn] ... (These are 20 cards I made. Comment yours below!) The first player to capture their opponent's king wins!

I think that when creating custom positions it should be possible to place teleports on the board and connect the teleports. I think being able to land on a square with a teleport should not be required for a piece to pass through a teleport. I'm thinking that some effects that teleports could have would be 1. Effective lateral connections between two squares so that it is as if one teleport is one square in front, behind or to the side of another teleport. For instance in this example if the two grey rooks represent two connected teleports, and the teleport on f11 is treated as being one square in front of the teleport on j6 the red knight could move to any square occupied by a dead knight. In this case the knight could teleport when passing through the square occupied by the teleport but it wouldn't be required to. So it would be as if there are two squares in front of j6. 2. Effective diagonal connections between two teleports For instance if the grey bishops represent two teleports that are connected and the teleport on h6 is treated as being 1 square behind and one square to the right of the teleport on i9 then the dead alfil-riders represent all but one of the squares the blue alfil-rider could move to, with the blue alfil rider also able to land on the teleport on h6. In this case the alfil rider could move to twice the number of squares it normally could implying that teleports on opposite colors may increase the values of normally color bound pieces. 3. Effective rotations For instance if the grey walls represent two connected teleports then the grey bishops would represent every square the green bishop could land on except for the squares the teleports would be on. In this case passing through the teleport would divert the bishops movement 90 degrees clockwise. or in this example if the clear walls represent connected teleports and the grey camels represent squares the yellow camel could move to then passing through the teleport would reverse the camels direction. I think it should also be possible to connect a teleport to multiple other teleports, at least if the ways it connects to each other teleport is different.

Does anyone play on the chess variant site Greenchess.net?

I was thinking that there should be an option to customize the forward direction of a pawn independently of the color of the pawn. A suggestion I have for how to customize the pawn directions is to allow the game creator to place an arrow over a pawn to specify what direction the pawn would treat as forward. For instance in this position if a left arrow was placed over the red pawn then the pawn could move to g2 even if sideways pawns was not enabled as it would treat g2 as being the square immediately in front of it. With a left arrow placed on the red pawn if there was something on g1 or g3 the pawn could capture it, but could not capture something on i3. I was thinking that all pawns that treat the same direction as forward could have the same promotion squares regardless of color. For instance if the blue pawn had a right arrow it would promote on the squares a yellow pawn would normally promote as it would treat the same direction as forward as a yellow pawn normally would.

I saw the new "who is streaming button" and I was wondering how to get yourself added there because I would like to stream atomic.

There used to be a variant (I believed called something like Automatic Chess) where you would set up pieces in some configuration and the engine would play out the position. Is there a way to still play this variant on Chess.com? I cannot find it in the Variants section. Thank you

I've been on 3: fog of war, giveaway, and atomic. I was wondering the leaderboard tally of other people. Has anyone else been on more? I didn't make this out of ego- it's just that i'm curious like a cat. ;P Also extra points if you have been on more than one at the same time .
