Learn How to Mate in 3: Sacrifice & Fork
This middlegame puzzle is a classic example of how a sacrifice can open lines and create a forced mating net. White’s attack works because the enemy king is exposed, key defenders are overloaded, and the g-file becomes a highway for the heavy pieces. The idea is not to win material first, but to force the king into a worse square and remove the last shield around it. In classical chess, these patterns often decide the game immediately.
