Philip M. Cohen

Philip M. Cohen is the inventor of several chess variants. He authored the column "Olla Podrida" in the periodical "Nost-algia" published by the (now defunct) correspondence game club NOST. The column regularly featured chess variants, many experimental, since 1972.
Reincarnation Chess.
This variant by Cohen uses the same board and pieces as standard chess, but a captured piece can make its presence felt on the board as a "zombie", and can "reincarnate" another zombie back into the game by capturing it.
Move rules.
When a capture (or series of captures) takes place on a square, a "zombie" is created when the capturing piece leaves the square. The zombie assumes the same piece type as the (last) piece captured, and the color of the capturing player.
There is no "en passant" capture in Reincarnation Chess.
