chessCAMO is a newly proposed chess engine with a built-in variant that stands for Calculations Always Make Opportunities and was inspired by the very popular chess variant Crazyhouse. The "CAMO" portion comes from the idea that in this variant a player can sacrifice making a move to replace one of their pieces from the "piece reservoir".
