About Chess
Chess has been played for roughly 1,500 years, evolving from the Indian game chaturanga into the modern rules standardized in the 15th century. Two armies of sixteen pieces battle across 64 squares, and the goal is timeless: trap the enemy king in checkmate.
This browser chess game gives you the White pieces against a computer opponent with selectable difficulty, which controls how far ahead the engine looks. Every standard rule is enforced — castling, en passant, check, checkmate and stalemate — and pawns reaching the last rank are promoted automatically to a queen. You can undo your last move, review captured pieces, and play chess online free with no account or download.
