Carl Schlechter (White) Puzzle: Stalemate — Rook Sac
Stalemate is a powerful drawing resource in the chess endgame, especially when one side appears to have a comfortable material advantage. The key idea is to surrender an active piece with check, forcing the opponent to capture it. After the exchange, the attacking king may have no legal moves, while a blocked pawn cannot move either. This creates a stalemate position instead of a lost ending. Recognizing this defensive resource requires examining the opponent’s legal moves after every forcing exchange.
