Learn How to Skewer: Decisive Material Gain
This middlegame puzzle comes from the Vienna Game and shows how a skewer can turn a strong tactical idea into a decisive material gain. The key feature is that Black’s active bishop creates pressure near White’s king, but that same activity also leaves pieces aligned on vulnerable squares. In positions like this, the best move is often a forcing check that drags the king into a worse square and exposes a high-value target behind it. The result is a classic tactical refutation, not a quiet positional squeeze.
