Learn How to Spot a Short Skewer: Decisive Material Gain
This middlegame puzzle is a classic example of a short skewer: a forcing check creates a direct line on a more valuable piece behind a less valuable one. The key idea is that the king’s limited mobility turns a tactical threat into a material win. White’s heavy material edge is not enough if the king is exposed and the back rank and central squares are vulnerable. In classical chess, these tactical refutations often decide the game immediately.
