Learn How to Spot a Mate in 2: Queenside Attack
This puzzle comes from the Nimzowitsch Defense and shows how a queenside attack can turn into a forced mating net in the middlegame. White’s king is relatively safe, but Black’s pieces and queen activity create a direct tactical threat against the king’s shelter. The key idea is that active piece placement can outweigh material equality when the enemy king lacks escape squares and the defending pieces are poorly coordinated.
