Learn How to Win Material: Long Sacrifice Skewer
This puzzle is a classic example of a winning combination built around a long sacrifice and a skewer. Black uses active rooks and a vulnerable king position to force the white king into a bad square, then converts the attack into decisive material gain. Even though White appears to have extra material, the exposed pieces and loose back-rank coordination make the position tactically fragile. The key idea is that activity can outweigh static material in a sharp middlegame-to-endgame transition.
