Learn How to Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a forcing mating net built around the enemy king’s limited escape squares. Even when material is balanced or favorable, a loose back rank and overloaded defenders can turn into immediate disaster. The key idea is to create a check that drags a defender onto a critical square, then finish with a second forcing move that seals the king’s fate. In classical chess, these patterns often appear when active rooks and queen coordination meet an exposed king.
