well i am a +1, but the rules are a bit hard to get, and worse than that, i have no one to play it with otb
A new variant suggestion: Backwards Chess

This is really cool
Might be a little hard to play otb without experience to quickly tell the difference between a bluffed check and actual check.

I think what the name suggests is much more interesting.
The game begins as a challenge: One player posts an endgame that is either a stalemate or one King is in mate.
A player accepts the challenge by picking one of the two sides. If it is stalemate and there is ambiguity he may need to declare which side moved last.
Play proceeds by players undoing moves in natural order, in each move required to make the reverse of a valid chess move. In their own move a player may also return any "captured" piece to the board in a fashion which would retain the validity of the other players already determined move.
Uncastling commits the player to subsequently not move either of the two pieces involved in the maneuver.
The first player to successfully return all his/her pieces to their starting position wins the game.
An interesting feature of this variant would be that unless pawns are stacked or black-white reversed in the initial position one will see few captures with pawn as reversing a pawn capture forces the opponent to return a piece to the board, to retain the validity of the move.
I'm unsure how to handle unpromotion, as it may create very complex problems depending on the setup position. One could have a feature in which unpromotion is forbidden, in which case certain piece combinations in the initial position would also have to be forbidden.
I created a chess variant called backwards chess. I will try to explain the new rules.
Set Up:
The set up at the start of the game is the same as normal.
Main Changes:
The main change is when you capture a piece, the captured piece is gone, but the capturing piece goes in the opposite direction. For example, if there is a knight on f3 and a pawn on e5, and the knight wants to take the pawn, the knight would go backwards to g1 after taking the pawn. This is why it is called backwards chess. If you want to do a capture, you click on the capturing piece and then the captured piece. Do not click on the backwards square. If you click on the backwards square, then the piece would just go that way instead.
Moving without capturing:
If you move a piece, but do not capture anything, then there would be no backwards movement. Moving without capturing is pretty much the same as normal.
Double Capture:
If it turns out that there was a piece that was on the square that the capturing piece ends up on after going backwards, then the capturing piece would also capture the second piece even if the second captured piece is on the same team as the capturing piece. It is illegal to do a capture if the second captured piece is your own king.
Jumping over pieces:
When the capturing piece moves backwards, it doesn't matter if there are pieces that it jumps over to go backwards. It just jumps over them.
Going off the board:
If the capturing piece is close to the edge, but the piece that the capturing piece wants to capture is far from the capturing piece, it might not be possible to capture because then the capturing piece would fly off the board after going backwards, so this kind of move would not be legal. The capturing piece should never disappear or go off the board. The move would just not be allowed.
Ending up in check:
If the enemy king can be captured from the double capture, then the enemy king is in check and must escape check. If the enemy king can not escape, that is checkmate. There shouldn't be such a thing as a king being captured.
Bluffing Check:
If a piece tries to check the enemy king, but the checking piece would go off the board, the enemy king can't be captured, so the enemy king is not in check. The enemy king would not have to do anything to protect itself from the fake check.
King capturing into check and then moving backwards out of check:
The king can capture a defended piece into check as long as the king is not in check after moving backwards. This idea makes it hard to defend any of your pieces.
Castling over a fake check:
If the king moves over a square that is under the fake check, then the castling would still be allowed. Also, if the king is in fake check that does not prevent the king from castling.
En Passant:
If you do an en passant move from d5 to e6, the capturing pawn would move backwards to c4 not c5.
King Opposition at the edge:
It is possible for the attacking king to attack the enemy king at the edge of board because the enemy king can not capture the attacking king and go off the board. This would be checkmate if the attacking king can move backwards, but then the enemy king might be able to move to the side, but not so if the attacking king can capture from that angle too. Remember, there is no such thing as capturing a king. It would be checkmate before it comes to that. It is also possible for the enemy king to be on g8 and you move your king h6 to h7. The kings would be touching, but it's just fake check and similarly for other corners on the board.
Strategy:
You can checkmate with the kiss of death with the queen without defending the queen because pieces at the edge can't capture away from the edge. It might be a good strategy to move pieces closer to the center so that they will be able to capture.
Experience:
I've played this variant about 10 to 20 times before. It seems fair for both sides. I haven't put it through a computer to see if white or black has a huge advantage because I don't know how to code that.
I already sent this variant in the suggestions. I clicked on Help and then Make a Suggestion. I'm also putting it here because I think this is where I am supposed to put it. Make sure you don't get confused about the same variant suggestion. Feel free to email me if you have any questions about the variant. I put the email in the suggestion. Or maybe you are supposed to comment on this post? It would mean a lot to me if this becomes a playable variant on chess.com. Alternatively, if this does not become playable on chess.com, but you are interested in it, you can play at home with a real board or something. You might find it interesting. Thanks for reading if you made it this far.
