Mutation Chess is also know as FRANKFURT CHESS.
This Variant has been invented in 1986 by John E. Bosley (New Zealand).
The rules of FIDE Chess apply with this change:
The capturing piece turns into the captured piece without changing color, i.e., when a white pawn takes a black rook, the white pawn turns into a white rook.
