Very intresting, would love to give tjat a go! We could do a match like that if you want!
Chess Variant: Ice Chess


Suggestion;
Knights would also slide after moving, in the relative direction they moved.
If that means it stops halfway between two squares, oh well, then we have an out of bounds glitch in chess. Surely that's a world record.

Suggestion, maybe make an extra piece called the yeti that can be achieved by pawn promotion and move like the king, and they can set bumpers on edge squares occupied by ally pieces as the players turn to make pieces bump off the board a couple of times before being removed.
I'm thinking about 10 durability, with knights and bishops doing 2 damage, rooks doing 3, kings doing 5, and queens one shot. The bumpers will lose 1 durability every 3 turns, and can be removed at any time if a yeti is still intact.
I'd love to hear where this could take us in the variant!
> Rooks, bishops, and queens MUST move as far as they can in the direction you choose, stopping when they bump into a piece (whether friendly or enemy), capture a piece, or hit the side of the board.
> Pawns MUST use their initial double-step move. En passant is permitted like normal.
