BDG Huebsch John Crompton

Huebsch Gambit avoids Blackmar-Diemer Gambit in theory by not in spirit. The Huebsch keeps the feel, the tactics, and the strategy of the BDG. White has five reasonable responses after 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 (3...dxe4 4.f3 is a BDG) 4.Nxe4 dxe4. Options include 5.Bc4, 5.Be3, 5.Bf4, 5.c3, or 5.f3. Those interested in critical variations can find my detailed analysis in Blackmar-Diemer Theory 4.

Black is up a pawn but is missing the helpful Nf6. White does have compensation. If Black is rated over 2000 in a slow game, then White has his work cut out for him. If Black is rated below 2000 in a blitz game, White's chances skyrocket.

John Crompton as White (JECmate) prefers the logical 5.f3!? If Black accepts with 5...exf3 then in theory White has full compensation for the gambit. In practice, Black grabs the pawn about half the time. Crompton demonstrates that White can win quickly because he makes immediate threats that must be taken seriously, or else it's mate.
