Learn How to Win with an Intermezzo: Sicilian Defense

This puzzle shows a classic opening tactic where a forcing intermediate move changes the evaluation immediately. In the Sicilian Defense, one side often relies on active queen placement and quick development, but that can backfire if the queen becomes overextended. The key idea is to use tempo: first create a forcing check or capture that improves your position, then take advantage of the exposed queen and loose pieces. In classical chess, these tactical refutations often decide the middlegame before it really begins.
