Blackmar-Diemer Gambit 2. e4
2. e4
White offers his e4 pawn in exchange for quick development and open lines. At the professional level this move is considered somewhat suspect, but black must be careful if he chooses to take the pawn as there are many traps in this opening.
2 ...dxe4, accepting the pawn, is the Blackmar-Diemer Gambit.
Black has three ways to decline the gambit.
- e6 transposes to the French Defence
- c6 transposes to the Caro-Kann Defence
- Nc6 transposes to the Nimzowitsch Defence
- c5 is a largely unexplored countergambit.

2...dxe4 (Blackmar-Diemer Gambit (BDG)) White has given up his king's pawn, in hopes of an aggressive game. Since there is no way White can win a pawn back immediately, he can expect this set-up most times he plays the Blackmar-Diemar Gambit. Lichess Analysis - Wikibooks (15776664 games)
2...c5 (Countergambit) After dxc5 dxe4 (Nf6 seems better), Qxd8+ is possible, which looks stronger than it is, due to Kxd8. This is the earliest possible queen exchange. Lichess Analysis - Wikibooks (746173 games)
