Learn How to Spot a Boden Mate: Queenside Attack
This classical chess puzzle comes from a sharp middlegame where the king is still in the center and the queenside is overloaded with tactical targets. The key idea is a forcing queenside attack that uses check to drag a defender away, then finishes with a bishop-and-knight mating pattern. Positions like this often appear in the Nimzowitsch Defense when one side has developed pieces aggressively but left the king vulnerable to a direct tactical refutation.
