Learn How to Mate in 3: Mating Net
This puzzle is a classic mating net in the middlegame, where king safety matters more than material. The attacking side uses a sacrifice to drag the enemy king into a vulnerable square, then follows with forcing checks that restrict escape routes. The key idea is attraction: once the king is lured onto the wrong square, the remaining pieces coordinate to seal every flight square and deliver a forced finish. In classical chess, these patterns often decide games instantly.
