Sicilian Defense Intermezzo Puzzle (Rated 896): Use an Intermezzo — Crushing Sicilian Wing Gambit
This puzzle shows a classic opening intermezzo: instead of recapturing or trading immediately, White uses a forcing check to improve the position and win material. The key idea is that Black’s queen has wandered into the center and becomes vulnerable to a tactical refutation. In sharp classical chess positions, a single forcing move can expose king safety problems, remove the defender, and turn an active-looking queen into a liability.
