Learn How to Spot Mate in 2: Queen-Rook Coordination
This chess puzzle comes from the Accelerated London System and shows a classic middlegame mating pattern. The key idea is coordination between queen and rook to exploit an exposed king and a weakened back rank. Once the forcing check lands, the defender’s king has no safe squares and the follow-up is unavoidable. In classical chess, these short tactical finishes often appear when development and king safety matter more than material.
