Learn How to Spot a Skewer: Decisive Material Gain
This middlegame puzzle is built around a short skewer, a classic tactic where a more valuable piece is forced to move and a lesser piece behind it becomes vulnerable. In this Four Knights Game structure, Black’s active piece placement creates immediate pressure on White’s queen and the rook behind it, turning a seemingly ordinary developing move into a winning tactical sequence. The key idea is not a direct attack on the king, but a clean gain of material through alignment and piece coordination.
