Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic example of a tactical refutation based on loose pieces and direct material gain. White’s queen is active, but it is also vulnerable because the position contains tactical pressure on the center and back rank coordination issues. The key idea is to notice when a seemingly strong move can be answered by a forcing capture that wins material and changes the evaluation immediately. In classical chess, activity only matters if your pieces are safe.
