Learn How to Refute: Tactical Refutation
This puzzle is a classic tactical refutation in the middlegame: one side’s active pieces and loose coordination create a forcing sequence that wins material decisively. The key idea is to exploit an overloaded defender and a vulnerable piece on the e-file, then use the resulting check to keep the opponent tied down. Even though the position looks balanced materially, the dynamics favor the attacking side because the defender cannot cover every threat at once.
