Balestra Mate Puzzle (Rated 977): Spot Balestra Mate — Mate in 1

This puzzle is a classic balestra mate pattern in a sharp middlegame, where the attacking side uses a bishop to deliver immediate checkmate on a vulnerable king. The key idea is that the king’s escape squares are already controlled by your pieces, so the final checking move is not just a check but a complete net. In positions like this, king safety matters more than material, and a single forcing move can end the game instantly.
