Summary: One of Martin Gardner's most famous columns introduced John Conway's Game of Life. The inverse problem, finding a previous generation in the Game of Life given some extra constraints, was introduced a few years ago and is referred to as Retrolife. In this paper the author presents a puzzle played on a chessboard that is isomorphic to a variation of Retrolife.
