Learn How to Win Material: Intermezzo Tactics
This middlegame puzzle is a classic example of tactical refutation based on hanging pieces and an intermezzo. One side has an exposed rook and an unprotected back-rank weakness, so the strongest reply is not a direct recapture but a forcing move that creates check first. That extra tempo changes the evaluation immediately and turns a seemingly normal material grab into a decisive gain. In classical chess, these in-between moves often decide games because they exploit coordination problems before the opponent can respond.
