Mate In 3 Puzzle (Rated 1557): Mate in 3 — Endgame Tactics

This chess endgame puzzle is a classic forcing sequence where the attacking side uses a queen to drive the enemy king into a mating net. The key idea is not material gain, but coordination: checks, forced replies, and the defender’s limited squares. In positions like this, a seemingly active defensive piece can actually become a tactical liability because it blocks escape routes and helps create a mating pattern. Recognizing the king’s lack of flight squares is often the first step toward finding the finish.
