Learn How to Use an Intermezzo: Decisive Material Gain
This middlegame puzzle shows a classic intermezzo idea: instead of recapturing or reacting passively, White inserts a forcing check that changes the whole tactical picture. The key is that Black’s queen is overextended on the kingside while the dark-square pieces are tied to defense. In positions like this, a forcing move can expose loose coordination, win material, and leave the opponent’s king with no comfortable way to regroup.
