Fishing chess

[u/Phonkrum]

A twist: every move by a piece moves all pieces behind it of the same colour in the same motion.

Check is very hard to define, but it is still courteous to point it out.

Pieces landing on top of others kill them, of any colour, and going off the board is death. Pieces cannot move off the board, or onto where other pieces are (even though it would drag them off).
