Greek Gift — The Classic Bishop Sacrifice
Objective: Task goal: find the forcing attack and deliver checkmate in the fewest possible moves.
Position and task condition
Black's king appears safe after castling, but there is a serious weakness in the defensive setup. White has a bishop aimed at h7, a knight ready to join the attack and a queen that can quickly enter the kingside. Find the way to open the king's position and carry the attack through to the end.
