Learn How to Use Intermezzo: Decisive Material Gain
This Vienna Game middlegame is a classic example of an intermezzo tactic: instead of recapturing or defending in the obvious way, Black inserts a forcing check that changes the whole position. The key idea is to exploit king safety, loose pieces, and the fact that White’s advanced pawns and undeveloped pieces are vulnerable to tempo-gaining threats. In practical classical chess, these forcing moves often decide the game by winning material or creating a decisive attack.
