Alekhine Defense Osullivan Gambit Beginner (1.e4 Nf6 2.e5 Nd5 3.d4 b5 / 1.e4 Nf6 2.e5 Nd5) in Chess

The alekhine defense osullivan gambit beginner refers to a rare sideline in the Alekhine Defense where White tries to meet 1.e4 Nf6 with an early gambit idea, but the exact move order is not widely standardized in common opening references. Because this is an obscure branch of the Alekhine family, the defining feature is less a famous mainline and more the early tension around White’s central pawns after Black’s knight attack on e4. For a beginner, the key point is that this is still an Alekhine Defense structure, just with an uncommon gambit attempt layered on top.
