Semi Slav Defense Discovered Attack Beginner Puzzle (Rated 1450): Spot a Mate in 3 — Bishop Sacrifice

This puzzle is a classic middlegame mating attack where White uses a bishop sacrifice to tear open the enemy king’s shelter. The key idea is clearance: a piece is removed to open lines for a discovered check and a forcing follow-up. Black’s kingside pawn cover is already weakened, so the attack works by combining piece activity, open diagonals, and direct pressure on the king rather than winning material first. It is a strong example of a tactical refutation in classical chess.
