Grob Opening London Defense Puzzle (Rated 1325): Crush the Exposed King — Decisive Material Gain

This middlegame puzzle is built around an exposed king and active heavy-piece coordination. Black’s pieces are already aimed at the king zone, and the key idea is to force the white king into a worse square while keeping tactical pressure on loose pieces. The position rewards spotting forcing moves first, especially checks that improve piece activity and create direct threats against the king and the queen. It is a classic example of how king safety can outweigh small material differences.
