Post your chess variant ideas here!

I recently (ok, always) got a intrest in chess variants, and i suddenly wondering "what do other people have for chess variant ideas?" and, this is me finding out. so, post your chess variant ideas here!

So what if we made all the pieces pawns, and both players have 12 of them. And now imagine the pawns can only move one diagonal space forward and you can jump over your opponent’s pawns to capture them. It would be really convenient that all the pieces are the same. You could even use like, I don’t know, little discs instead of actual pawns.

i belive checkers already exists

No no, I’m pretty sure I’m the first person to think of this

I'm a game developer and somehow, my every solo project turns into some sort of chess variant. Right now my most recent game is a single player game where you are just a lone pawn and you have to escape the board filled with other evil chess pieces.

i would love to see that!

i would check it out, but my cromebook can't open the tab. i bet its pretty cool though!

Normal Board and pieces, except bigger pieces (K>Q>R>B+N>P) can push smaller pieces, knights and bishops can push each other. Say if a rook was on a1 and a pawn was on a2, the rook could to go a5 and push the pawn to a6. The king can also wear pawns for protection so if he's captured the pawn dies and the attacking piece ends up next to the king.

cool idea!

My variation "The Lance Rule" is for competitions and can be used in all levels of play.

The first move by each side will be played by the opponent.

Chess but 10 more extra pawns, no queen, bishop is in rook's position, rook in bishop's position, knight is beside the king and its origin position. You promote in the 12th rank + 512 total squares + duck chess but it's a turkey + 1 hour but every move is a -20/15 seconds decreased + You can skip your turn but if you and your opponent skips 3 times it will be a draw + baby shark background song + fullscreen + voom sound effect everytime you move a piece + after the end of the game, if you lose you lose the amount of points based on the seconds you lost. If you win you win the amount of points based on the material value x2 + you can't resign unless you have a reason other than losing + you can't chat with the opponent + blured board for 5 seconds every 1 minute wasted.

Torture Chess Variant.

Advantage chess, like setup chess but you have the normal starting position, when your piece gets captured, you get points equal to that piece -1, also you can only place on the 1st rank (pawns placed on 2nd rank)

Two ideas:

First is more of a new format idea leagues and round robins. In this variant, there are no resignations; you get 1 point for a checkmate with a queen, 3 for a checkmate with a rook, 5 for a mate with a bishop or knight, and 9 for a mate with a pawn. A double checkmate (has to be pure) gives you the points for both pieces; a smothered mate gives a bonus of +15. In some league situations this could easily lead to some very adventurous chess, perhaps where both players need a spectacular points win to qualify / get promoted / avoid relegation and pass up on some easier checkmate opportunities. Though, of course, it could easily be taken advantage of if your league position is secured and you know your opponent needs a bishop or better mate and so you could take risks you otherwise wouldn't.

Second idea, less exciting, bit weirder, not sure whether it's even viable, but the option for pawns to promote to a second king rather than a queen, the opposition needing to take one of your kings first before checkmating the other. Would probably need to be folded into some other ruleset change otherwise it's just not going to come into play often enough to justify it's existence.

Here is my best variant so far. I call it 4 Room Chess.

Rules

4 player diplomatic, meaning you can create alliances during the game and team up with other players. This is normally prohibited for 4 player variants but the  "Diplomacy" rule is the exception. You can also use secret arrows and messages but I haven't figured out how yet. 

Play for points, that is you try to have the most points at the end of any game, capturing pieces, and checkmating give you points.

It is a takeover variant meaning if you checkmate other players, you get all there pieces. 

N check meaning if you get checked 12 times you loose.

Pawn promotes on 14th rank to 1 point queen

Setup

There are 4 6 by 6 boards that are each connected to the adjacent board with a 4 by 4 square. Each player gets two sets of pieces, each is located above or bellow the other one. One set has the royal king, the one that gets checked, checkmated, and stalemated. The other one can be captured without you loosing. 

Because of the setup, I had to use Wazirs instead of pawns (pawns can only move one direction for each player, for example, if your red, your pawns can only move upwards, not sideways or down. But in this game each player has 2 setups facing different directions meaning pawns should be able to move in 2 directions). Wazirs can move to any square directly next to it and not diagonally. this means it only has 4 squares it can move to. 

I have tested this one extensively

Guess Chess

1 Same Move Rule
Both players confirm (to themselves) where they are going to move (or plan it on two private boards), then when they are both ready, they both place down their pieces at the same time. If you are playing on one board, you can NOT move based on where your opponent is moving, what piece they are touching, their facial expression, etc. you MUST be honest and move where you planned, even if you end up loosing.

2 The Exchange Rule
If both of the player's pieces attempted to capture each other in a move, then they will both be taken off of the board. for example: if white moves his/her piece to a square where black's was, and black moves the targeted piece to the square where white's was, then both of the pieces are considered captured and will be taken off of the board. This means that:

A: If two kings are next to each other (see rule 7), they can both capture each other, and it's a draw.

b: One king can capture the other king, and the captured king loses.

3 The Happenstance Rule
If both players move a piece to the same square, both pieces are considered captured and will be taken off of the board. if both players move to a square where there is already a piece (see rule 8), then all THREE pieces are considered captured.

4 The Evade rule
If white moves to capture one of black's pieces, but black evades his/her capture and moves to a different square, then black's evading piece will NOT be captured.

5 The Obstruction Rule
If a piece moves to capture an opponent's piece, but the opponent moves a piece in front, the piece that moved in front will be captured instead. In simpler terms, the obstruction will be captured, not the target. (this does not apply to pawns or knights because you can't block a pawn or knight attack.)

6 The Pawn Rule
If white moves a pawn and attempts to capture a black piece, but black evades the capture (see rule 4), the pawn remains where it was even though it can not normally move diagonally (f) without capturing a piece.

7 Capture The King
There is no check or checkmate. You can move into check. This means that:
A: a king can remain in check

8 Any Capture
You can capture any of your own pieces (even the king). 

Swap'n chess

Swap'n chess is a chess variant where you have the opportunity to swap pieces with your opponent.

1 Swap'n rule
You can spend a move swapping a piece with your opponent, similar to crazyhouse were placing a piece is considered a move, just now it is swapping that is a move.

2 Same piece rule swap'n
You can only swap pieces with your opponent if they are the same piece. For example, black swaps his knight for one of whites knight. You can only swap bishops on the same color.

3 No swap'n back
You can not swap what your opponent just swapped. Also, you are not allowed to swap either piece with anything if it was just swapped. But you can move your just-swapped piece. If your opponent swaps two pieces, and you wait 2 moves, then you can swap it back.

4 No king swap'n
You are not allowed to swap kings at all during the game.

5 unmoved piece swap'n rule
You are not allowed to swap with a piece that has not moved from the starting position, this aplies to all pieces.

Check roulette

Dice chess is a chess variation. ever time you get checked you role the dice and depending on what you land on, the following things could happen:

• If you land on 1-2 you lose a pawn
• if you land on 3 you lose a bishop or knight
• if you land on 4 you lose a rook
• if you land on 5 your enemy chooses what you loose (Kings and Queens are not options)
• if you land on a 6 you lose nothing

1 If your enemy puts you in check, you must roll the dice before moving a piece. 

2 If you roll on a number where you can lose more than 1 piece, you choose which one you want to lose. For example, If you land on 3 and you have 1 bishop left and one knight left, then you choose which one you want to lose. You never lose 2 pieces after rolling the dice.

3 If you roll a number with a piece that you don't have anymore, then you roll again, if you don't lose anything on the 2nd roll, then you stop rolling and move your piece. For example, If you roll a 2, but you don't have any pawns left, you would roll again. If your next roll was a 1 or 2, then you would stop rolling and move.
