Sacrifice Puzzle (Rated 1419): Win with a Queen Sacrifice — Crushing Endgame

This puzzle shows a classic crushing endgame idea: using a long sacrifice to drag the enemy king into a mating net. Even when material is down, active pieces and king safety can outweigh raw count. The key is that the defender’s pieces are overloaded, and one tactical capture opens lines toward the king. In classical chess, these moments often decide the game immediately because the exposed king has no safe shelter and the remaining pieces cannot coordinate in time.
