Naselwaus Gambit

The Naselwaus Gambit, 3. Bg5, disregards the pressure that 2...Bb7 puts on e4 and develops the dark-squared bishop instead, so the e-pawn is left hanging. Taking it with 3...Bxe4 is the most frequent answer, and Black scores well after it. Nearly as common is 3...h6, which questions the bishop at once, while 3...Nf6 is less often chosen. Engines judge the position as roughly balanced, and the line remains a rarely played sideline.
