Sacrifice Puzzle (Rated 1384): Win with a Long Middlegame Sacrifice — Fork

This puzzle is a classic example of a long middlegame sacrifice built around king safety and tactical coordination. White gives up material to open lines, force the enemy king into the open, and create a decisive fork-like sequence that wins back far more than was invested. The key idea is that active pieces and a vulnerable king can outweigh raw material, especially when the opponent’s queen, rook, or knight is overloaded or pinned.
