1D Chess is a minimalist chess variant played on a single row of eight squares. Each side commands just three pieces — a King, a Knight, and a Rook. Despite its apparent simplicity, the game hides surprising strategic depth. The game was conceived by legendary recreational mathematician Martin Gardner and first appeared in his Mathematical Games column in Scientific American in July 1980. Gardner posed the question: assuming optimal play, is there a forced win for White? Decades later, enthusiasts and computer scientists continue to explore this elegant puzzle.
