ChessAnalyzerBack-rank mate: chess tactics explained, with 10 puzzles
A king that has castled behind three unmoved pawns has no air. A rook or queen landing on its first rank is mate unless something can block or capture. Always check whether the enemy back rank is defended.
Every puzzle below comes from a real game position, and every solution was verified with Stockfish 18: each move you need to find is the only good move — the second-best alternative is at least two pawns worse. Try to solve each one before opening the solution.
