Learn How to Mate in 2: Back Rank Mate
This puzzle is a classic forcing finish in a middlegame where king safety matters more than material. White’s pieces are coordinated to exploit a cramped enemy king and a pinned defender, creating a mating net that leaves no useful escape squares. The key idea is attraction: a forcing capture lures the king onto a vulnerable square, after which the remaining attacker delivers a decisive checkmate. These patterns are common in classical chess and in tactical game reviews.
