Learn How to Spot Back Rank Mate: One-Move Tactic
This puzzle is a classic back rank mate pattern in a sharp middlegame. The key idea is that the enemy king has limited escape squares because its own pawns and pieces block the flight route. When a heavy piece can invade the first rank with support, the position can collapse instantly. Even if material is balanced or favorable, king safety can outweigh everything when the back rank is weak and the defender is overloaded.
