About the Blackmar's Second Gambit

Blackmar's Second Gambit is a branch of the Staunton Gambit in which White meets 3...Nf6 with 4. f3, undermining the e4-pawn in the style of the Blackmar–Diemer Gambit. Taking with 4...exf3 is the most common reply and gives White a half-open f-file and rapid development. The alternative 4...d5 supports the extra pawn from the center. Engines rate the position as balanced, while White scores well in practice.
