Learn How to Mate in 3: Pillsbury's Mate
This puzzle is a classic middlegame mating net where the attacking pieces coordinate to trap the king on the edge of the board. The key idea is that one forcing check drags a defender away, while the next check creates a smothered or boxed-in king. In classical chess, these patterns often appear when the enemy queen and rook are overloaded and the king has no flight squares. The position rewards forcing moves over material greed.
