Learn How to Spot a Mate in 2: Queenside Attack
This middlegame puzzle shows how a queenside attack can end the game in just a couple of moves when the enemy king is boxed in. The key idea is to use a forcing queen move that creates an immediate check and drags the king into a mating net. Even with material advantage, the side to move must look for the most forcing continuation, because quiet improvements are too slow when the opponent king has limited escape squares.
