Englund Gambit Complex Englund Gambit Kingside Attack Puzzle (Rated 1100): Mate in 1 — Bishop Checkmate

This middlegame puzzle is a pure king-safety tactic: White’s pieces are aimed directly at the enemy king, and the position contains a forced mate in one. The key idea is that a bishop can deliver a checkmate when the king’s escape squares are covered and the defending pieces are overloaded or pinned. In classical chess, these patterns often appear after a strong attack on the kingside, especially when the opponent’s king is boxed in by its own pieces and pawns.
