Nightmare on e4-street

Yesterday evening I played an interesting Blackmar gambit in our local chess club. I defended the black pieces and my opponent "wanted to play something aggressive". Now there is a slight difference between aggressive and correct. But this wont be an issue for the average Blackmar Diemer player I guess.

1.e4 d5 2.d4 exd4 3.f3
The Blackmar gambit, invented in 1882 by Armand Edward Blackmar.

3...e5
This countermove was quickly found by Oskar Cordel and buried the Blackmar gambit.

4.Be3 exd4 5.Bxd4 Nc6 6.Bb5 Bd7 7.Be3
Wanting to hold on to the bishop, interesting, but too slow

7...Bd6 8.Nc3 Nc6 9.Qd2 Qe7 10.000 000 11.Bg5 Bb4

My pawn at e4 is obvioulsy a huge problem for my opponent

12.a3
Obviously a mistake, as it weakens his kingside

12...Bf5
An even bigger mistake from my side. As soon as I played the move, I saw white's punishment

13.Qf4 Bxc3 14.Qxf5+ Kb8
A difficult situation has come up. White cant take the piece, but realises he has to develop quickly, but how ? My pawn on e4 becomes a real nightmare.

15.Rxd8+ Rxd8 16.Bxc6 bxc6 17.Ne2
Finally the white pieces get mobilised - but too late.

17...Rd5 18.Bxf6 Bxf6 19.Qh3 Bxb2+ !!
This morning, I see that my computer announces mate in 12 - impossible to see for me, a mere woodchopper - but I just sensed a mate was in the air as white's pieces are far away from the battlefield. Sometimes you just have to follow your instincts behing the chessboard.

20.Kxb2 Rb5+ 21.Ka2 Qc5 22.Rc1 Qd5+ 23.Ka1 Qe5+ 24.c3 Qc5 25.Ka2 Qd5+ 26.Ka1 Qb3 0-1

So dont try the Blackmar gambit, as the pawn on e4 is there to cripple your game for ever !!
