Pocket mutation chess
Chess variant
Pocket mutation chess is a chess variant invented by Mike Nelson in 2003.[1]
In this game, a player can take a piece from the board and put it into a pocket. The piece in the pocket can be put back on the board later. When placing the piece into the pocket the player can mutate the piece, i.e. change it to a different piece.
The game is one of the Recognized Chess Variants at The Chess Variant Pages.[2]
