Learn How to Skewer: Decisive Material Gain
This middlegame puzzle comes from the Slav Defense and shows how a short skewer can punish loose coordination. White’s active bishop and queen pressure the same line, creating a tactical problem for Black’s queen and rook. The key idea is that a lower-value piece can attack a more valuable piece while also exposing something behind it. In practical classical chess, these moments often decide the game by winning material and improving piece activity at the same time.
