Learn How to Crush a Fork: Tactical Refutation
This middlegame puzzle is built around a crushing fork and tactical refutation. White’s knight jumps into the enemy king’s camp with tempo, creating immediate threats against the king and a key piece. The position is especially instructive because the tactic works even though Black has extra material and active-looking pieces. Once the king is forced to respond, the follow-up wins more material by exploiting a trapped queen and loose defenders.
