Dubov Gambit

[edit | edit source]

6. b4

[edit | edit source]

White sacrifices the d4 pawn for quick development and an open d file. White also attacks the Black bishop on c5, forcing it to move. Black can play either 6...Bb6 or 6...Be7.

In contrast to the Evans gambit, White doesn't sacrifice the b pawn. Because of this White has the threat of b5, forcing the knight to move to a5 or e7.
