Blackmar Diemer Gambit Accepted Other Variations (1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3) Chess Puzzles

“Blackmar Diemer Gambit: Accepted, Other Variations” refers to the Blackmar–Diemer Gambit when Black accepts the pawn, but the game then steers into an accepted line that isn’t the most commonly named sub-variation. The defining feature is that after White’s early central pawn sacrifice, Black takes the offered pawn (the acceptance), and the position develops from there into a less-standard continuation rather than a single “main” accepted branch.
