#chess variant

The draw-by-repetition rule does a good job of keeping players from sliding a tile back and forth repeatedly, but the tiles definitely introduce some weird en passant and castling edge cases.

Chess Variant [Explained]

Transcript Under the Cut

[A chessboard is shown with the white pieces at the bottom of the screen. The pieces are illustrated in the basic design of standard computer chess. The chessboard is divided into 16 2x2 sliding squares with the e3-f4 sliding square currently being moved to the g3-h4 spot. Otherwise the opening is a standard Scotch Opening, with the pieces in the e3-f4 spot like how they are supposed to be]

Okay! So had 3am insanity and came up with a new chess variant: SUPERPOSITION CHESS.

On you're turn, you pick a piece and it'll move to every square possible in a superposition of sorts. When a piece gets moved all its prior superposition's get eliminated. A piece is removed from the board if taken in the classic sense or something makes it impossible for the piece to be there. taking with a pawn destroys all superposition since a pawn can only take if there is a piece there that can be taken (considering changing this rule...). To stop pawns being overpowered, pawns cannot take a piece if they (and the pawns on the files next to them) are on their starting rank.

after a quick game against myself, the mode is surprisingly fun and not insanely broken. You don't get overwhelmed by choices as you no longer care about where to move a piece, only which piece to move. Need better visual cues to help with board readability though also need to tighten the writing of the rules but its 3am.

example game below cut: next move highlighted in red. in a real game each piece would be labeled as to avoid confusion between pieces:

Breakdown of the game:

White opens with kings pawn and the Van 't Kruijs opening. Black responds with Kings pawn now the board is in 4 hypothetical states. White develops their white bishop, this moves a good example of why I restricted pawn's power, in this position blacks pawn could take white's bishop but since the a, b, and c pawns haven't yet moved, the b pawn can't take the bishop. Black develops their knight to take one of whites bishops in superposition. unlike pawns, taking the bishop doesn't break the superposition since the knight could move to a8 regardless of if the bishop was their or not (this is not the case with pawns). White moves their queen, losing one of their superposition's since the queen couldn't move if the bishop was on e2 (note in most cases, the queen and bishop would co-occupy said square but not in this case as the queen would be unable to move as stated before). This lines up an sneaky checkmate threat, since the queen (either on h5 or f3) is threatening to take f7 checkmate since the queen is defended by the bishop on c4. If the king takes the queen, then the bishop takes the king as the pawn blocking the path is in superposition so is necessarily on e6 (checks do not break superposition). There might be multiple counters, but the only one I've seen is to move the knight on c6, moving it to e5 (amongst other squares) defending f7. White pushes their f pawn to threaten the knight as the knight cannot move from e6 as that's checkmate but being taken by a pawn will lose all its superposition's. Luckily, white missed a check black can deal, threatening the rook in a fork and taking one of the queen's superposition's threatening checkmate. white in response takes the knight in superposition reinstating the mate threat. but that's a blunder, black takes the bishop and since that move is only possible if whites bishop takes h7, white loses all their superposition's meaning black's knight delivering the check returns to the board since the superposition that took it no longer exists!

speaking of chess variants, i always thought this would be fun:

at the beginning of the game, each player secretly writes down the name of a piece (eg. e-pawn, light squared bishop, queen). this can be any piece other than the king. this piece is a TRAITOR on the opponent’s team. once each player has made at least 10 moves, either player may at any point choose to skip their move and instead reveal what they wrote and take control of the chosen piece of the opponent’s color. it acts exactly as though it were the same piece of their color. if the traitor can “see” the opponent’s king, it is in check as soon as the player reveals the traitor’s identity.

My recent idea that turns Chess on its head.

Discord placed onions along their twelfth rank, Reddit planted pea shooters along the L-file aimed directly at Tumblr's pieces because "we cant loose against tumblr for fucks sake", and BlueSky took the L with their horsey.

Your move, Tumblr.

Revolutionary Chess: the king and queen are the only black pieces. Every other piece is white, and they are hunting them down to overthrow the monarchy and establish a constitutional republic. Maybe to make it slightly more fair there are a couple of loyalist pawns who stick by the old guard. Or the knights, sworn members of the kingsguard, whereas the pawns are just conscripts who owe the tyrant no loyalty. A knight is less likely to rise up against the crown than a peasant soldier or the clergy (I could very well see one of the bishops declaring himself king, with a rook as his advisor/prime minister)

What would you fall this? Civil war chess? Republican chess? People’s chess?

Here is my Oracle Chess.

Made a translation of the rules into German, Spanish, French, Polish, and Chinese.
