Pachman Gambit

The Pachman Gambit, 1. b3 e5 2. Bb2 Nc6 3. f4, attacks e5 at once with the f-pawn instead of first preparing the push with the quieter 3. e3. Capturing on f4 clears the long diagonal for the b2-bishop and opens the f-file, but after the usual reply 3...exf4 White has given up a pawn for little. Black can also choose 3...d6 or 3...e4. Engines rate the position as a large advantage for Black, who also scores well in practice.
