Learn How to Spot Mate in 2: Back Rank Mate
This puzzle shows a classic mating net where the enemy king is boxed in and the key escape squares are controlled by heavy pieces. The position is a sharp middlegame tactic, not a slow strategic squeeze, and the winning idea comes from forcing checks that leave the defender with only one reply. Once the first check lands, the follow-up is a simple conversion into mate because the back rank and pinned defenders cannot help.
