Alekhine Defense Osullivan Gambit Fork in Chess

The alekhine defense osullivan gambit fork is a tactical motif that appears in the Alekhine Defense after White plays the O'Sullivan Gambit idea, usually by advancing the g-pawn to create immediate pressure. The defining feature is a fork, most often by a knight, that hits two valuable targets at once in the early opening position. In this line, the fork is tied to the unusual pawn structure and the exposed pieces created by the gambit.
