Blackmar-Diemer Gambit

"Do you relish the prospect of setting your opponent awkward problems from the start of the game?" (Gary Lane)

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3

4... exf3 5. Nxf3 e6 6. Bg5 Bb4?! 7. Bd3 Nbd7 8. Qd2 O-O 9. Ne5 Be7 10. O-O-O h6 11. h4! c6 12. g4 Nd5 13. Bxh6 Bxh4 14. Ne4 Nxe5 15. dxe5 Be7 16. Nf6+ gxf6 17. Bh7+ Kh8 18. Bg7+ Kxg7 19. Qh6+ 1-0, Cole - Sea, 1994.

This is a lovely example of queenside castling, where White can advance the h-pawn effectively. Maybe this could also be tried when the pawn is on c4. In fact, had the moves c4 and a6 be played before 4. Nc3, the position after move 12 could have arisen from the DDG.

Some rare gambits after 1. d4 are very BDG-like
