Alekhine Defense Osullivan Gambit Intermezzo in Chess

In the Alekhine Defense: Osullivan Gambit, the “intermezzo” is an in-between move that forces the opponent to respond before you complete the main gambit sequence. A defining feature is that after the gambit tension, Black inserts a tempo-gaining or tactical move (the intermezzo) so White’s next move becomes less effective. This motif often shows up around the moment White is tempted to grab material or stabilize the center.
