Learn How to Use an Intermezzo: Tactical Refutation
This puzzle shows a classic opening trap in the Englund Gambit where an in-between move changes the evaluation immediately. Instead of reacting passively, the stronger side uses a forcing tactical refutation to expose the opponent’s queen and win material. The key idea is that checks and captures can be more powerful than recaptures, especially when the enemy queen is overextended and the king is still uncastled. In classical chess, this kind of intermezzo often decides the game on the spot.
