and instead of checkmating you must capture the king, making this is a game of strategy.
Chess already is a game of strategy. Also, this just makes it take longer, I'm not sure if it's a good idea. Worth trying though.
P.S. Please use notes for stuff like this, don't make a forum
Clinging chess is a variant where whereever your piece rook/queen/knight/bishop. moves. (not including pawns.) if theres another piece in a 1 square radius. they both cant move for 2 moves.

when a PAWN captures a piece everything in a TWO block radius gets clinged. if a pawn captures another pawn this may not happen.
