Sacrifice Puzzle (Rated 1497): Spot Mate in 2 — Chess Endgame Tactics

This puzzle is a classic forcing sequence where king safety matters more than material. In the middlegame-to-endgame transition, active pieces can create a mating net even when one side appears to be ahead. The key idea is to use a sacrifice to open lines around the enemy king and remove a defender. Once the king is dragged into a vulnerable square, the final attack becomes unavoidable. These are the kinds of patterns you see in classical chess and tactical game review positions.
