Here's an idea (probably not original): simultaneous chess. Both players write down their moves and, once they have both committed, both moves are executed in parallel. If two moving pieces end up on the same square, both are eliminated. If one piece moves onto a square that has been vacated by an opponent's piece in the same move then no capture takes place.
Addendum: One benefit of this variant is that it is completely symmetric and hence completely fair. There is no advantage for either side because neither side moves first.

- lisper 6y agoNot the same thing. KFC is real-time.
- Someone 6y agoFun idea, but what happens when a player submits an illegal move that becomes legal only when taking the opponents move into account or that’s only legal before the opponent’s move? Say a rook moving from a1 to a3 while an opponent’s knight moves from or into a2? Also, if you are going to write down moves, you can allow the players to move all of their pieces, too, like in Diplomacy. A queen could capture a pawn next to the king, and a bishop could simultaneously move to prevent the king from capturing the queen, for example. A countermove could be to move a pawn between that bishop and that queen, and to have the king capture the queen. ⇒ I guess this multi-move variant would get highly complicated very soon. It might be better to follow diplomacy here and replace “If two moving pieces end up on the same square, both are eliminated” by “...same square, neither moves”, or maybe add “x supports y moving to square S”*?
- lisper 6y agoI think I would specify that a move has to be legal when at the start of the move, i.e. while it is being written down.
- williamdclt 6y agoOr alternatively, the piece doesn't move if the move turns out to be illegal? Would have to try both options to see which works better
- lisper 6y agoThat would open up the possibility of a paradoxical situation where both moves are legal at the start but neither is legal at the end.
- Someone 6y agoSo, a king could move into a checkmate, even if it wasn’t in check at the start of the turn. Seems fine to me, but I think it would be funnier if a king in check could stay put, with the player in check betting that the opponent’s next move will end the check. There also is the possibility of simultaneous checkmate. Another edge case is pawns taking pieces. Could a pawn move diagonally into a square being vacated by the piece standing there? Could two pawns simultaneously not take out each other (say by the simultaneous moves d4×e5 and e5×d4)?
- lisper 6y ago> a king in check could stay put, with the player in check betting that the opponent’s next move will end the check. Yes, that was part of the intent. There is game theory in play as well as chess strategy. > There also is the possibility of simultaneous checkmate. Yes, or even simultaneous king capture without checkmate(s) resulting in a draw. Or you could adopt a quiddich-like rule and say that if the kings are simultaneously captured then the game is decided by the sum total of the remaining value of the pieces on each side. > Could a pawn move diagonally into a square being vacated by the piece standing there? Could two pawns simultaneously not take out each other (say by the simultaneous moves d4×e5 and e5×d4)? I would say yes and yes.
- leereeves 6y agoI wonder how such a game would end. With no way to block or capture a piece on the square it's attacking from, the first time the king is placed in check he has to move or be captured. If the king isn't completely surrounded, the attacker only wins if they successfully guess where (or if) the king will move. The endgame would include an element of reading the other player, like poker.
- lisper 6y ago> The endgame would include an element of reading the other player, like poker. Yep! Note that it is also possible for the game to end in a draw if both kings are captured on the same move.
- ggambetta 6y agoYou should try Diplomacy :)
- lisper 6y agoThat's where the idea came from :-) But I played Diplomacy almost 40 years ago (God help me), I wasn't sure if it was still a thing.
- ggambetta 6y agoDefinitely still a thing! I've picked up recently, there's a couple of websites where you can play for free. I've played in playdiplomacy.com.
