Master Chess is a fun online version of the classic board game chess. You can play this strategy game against other live players, or practice by trying to beat the computer. Are you a big fan of The Queen's Gambit? Move your pieces across the board and try to capture your opponent's king. If you lose your king, you lose the game, so be sure to protect this precious piece with your pawns, rooks, knights, bishops, and the queen. Try to force your opponent to create openings in their formation. Each piece can only move according to particular rules. Sacrifice the less valuable pieces to trap and take down the more versatile ones. If the king is under immediate threat of being captured (check), a player must always act to protect it. If no move can save your opponent's king (checkmate), you win the game!
