Learn How to Spot a Mate in 2: Pin Tactic
This middlegame puzzle is a classic example of how a pin can turn into a forced mating net. White’s heavy pieces coordinate against the enemy king, which is stuck in the center and short of safe squares. The key idea is that one defender is immobilized by an absolute pin, so any attempt to block the attack fails. In positions like this, the strongest move is often a forcing check that leaves the opponent with only one reply.
