My adventures with the Blackmar-Diemer Gambit...

Dave Regis 1 - 0 Kevin Kent
This was a fairly smooth game where for once I saw the problem coming and successfully avoided it.

BDG Vienna Defence

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5 5.g4 Bg6 6.g5 Nd5 7.Nxe4
Here I ran to the databases for some guidance. White has no Pawn deficit but needs a plan. The model game is Tartakower's, but Black can improve.

Black is being strangled. I love to play this way as White, even more perhaps than winning by a Queen sacrifice! Tartakower now gets in through the a-file while Black is too cramped to oppose it.
37.Qd3 Rb8 38.Ra2 Qb7 39.Re1 c6 40.Rea1 Rbd8 41.Ra7 Qb8 42.Rxd7 Rxd7 43.Qe4 g6 44.Ra6 Qd8 45.Ne2 Rd5 46.Rxc6 Bg7 47.Ra6 Bf8 48.Rb6 h6 49.f4 hxg5 50.hxg5 Bg7 51.Kg3 Bxd4 52.Nxd4 Rxd4 53.Qe5!

7...e6 8.c4 Nb6 9.Be3 Nc6

... This reminds me of an Alekhine's Defence: Black has no central foothold but White's centre is loose and may be undermined.

10.h4 Bb4+ 11.Kf2
[11.Ke2 O-O 12.c5 Nd5 13.a3]

11...O-O 12.Rc1
[12.c5 Nd5 13.a3 Ba5 14.b4 f5 15.gxf6 Bxe4

A) 16.fxe4 Qxf6+ 17.Nf3 (17.Kg2 Nxe3+;
17.Ke2 Nc3+) 17...Nc3 18.Qe1 Qxf3+;

B) 16.fxg7 16...Rxf3+ 17.Nxf3 Nxe3 18.Kxe3 Bxf3 19.Kxf3 (19.Qxf3 Qxd4+ 20.Ke2 Qxa1) 19...Qd5+ 20.Kg3 Qxh1]
...all looked fine for Black. Since then I hear from Jyrki Heikkinen that he can improve with 12.c5 Nd5 13.a3 Ba5 14.Qd3...

12...Bxe4
[12...e5 13.d5]

13.fxe4 f5
[13...f6]

14.exf5
[14.gxf6 e5 (14...Qxf6+ 15.Nf3 e5 16.Bg5 Qg6 17.c5) 15.c5 Qxf6+ 16.Nf3;
14.c5 fxe4+;
14.e5]

14...exf5

[15...g6 16.d5 Ne7 17.a3; 15...Qe7; 15...Qe8; 15...Be7 16.d5 Nb4]

16.Bd2 Qe7
[16...Bxd2 17.Qxd2 Qe7 18.Bh3 Qe3+ 19.Qxe3 fxe3+ 20.Ke2 (20.Kxe3 Rae8+ 21.Ne5 Nxe5 22.dxe5 Rxe5+ 23.Kd4 Rfe8=+) 20...Rae8 21.d5 Ne5 22.Nxe5 Rxe5 23.Be6+ Kh8 24.Rhf1;
16...Be7 17.Bc3+=]

Now the position reminds me of a King's Gambit!

CRITICAL POSITION: Black has an advanced protected passed Pawn, but needs to find a way of making use of it - or else he will be driven back. I spent a long time analysing this move, because if a planned finesse at move 21 doesn't work, this is the place to repair it.

17.Bh3
[17.d5 Ne5 18.Bxb4 (18.Nxe5 Qxe5 19.Bxb4 Qe3+ 20.Kg2 Qg3#) 18...Qxb4 19.Nxe5 Qxb2+ -+]

17...Bxd2
[17...Rae8 18.Re1 Qf7 (18...Qd6 19.Rxe8 Rxe8 20.c5) 19.Bxb4 Nxb4 is also critical;
White may still be able to claim an edge because of the unstable Black Knights. 20.a3]

18.Qxd2 Qe3+ Tempting but probably mistaken.
[18...Rae8 19.Rhe1 Qf7 20.d5 Rxe1 (20...Nd8) 21.Qxe1 Nd8 22.Ne5 (22.b3 Re8 23.Qa5 a6;
22.Qd2 Re8 23.b3) 22...Qe8 23.b3 Kh8 24.Rd1 Nf7 25.Nxf7+ (25.Be6 Nxe5 26.Qxe5 Qh5 27.Rh1 c6) 25...Qxf7 26.Be6 Qh5]

19.Qxe3 fxe3+ 20.Ke2
[20.Kxe3 Rae8+ didn't detain me long, so White must concede the Pawn another step forward. I think Black must have mis-assessed this line with Ke2, or surely he would have chosen something else earlier.]

20...Rae8
Now Black has a little opportunity to play ...Rxf3 and ...Nd4+, so White must anticipate this by enabling Be6+ interfering with the line of the Re8.

21.d5!?

[21.b3 Rxf3 22.Kxf3 Nxd4+ 23.Kg2 e2 24.Kf2 h5 25.gxh6 gxh6]

21...Ne5
[21...Rxf3!? looked alarming but 22.Kxf3 (22.dxc6 Rf2+) 22...Nd4+ 23.Kg2 e2 (else Rd1) 24.Be6+ and I think White comfortably survives to win.]

22.Nxe5 Rxe5
[22...Rf2+ 23.Kxe3 Rxb2 24.Be6+]

23.Be6+ Kh8 24.Rhf1

Now it's all over: White will consume the e-Pawn and the poor Knight still has nowhere to go. Black has rather drifted into this lost position without having a definite plan for counterplay. Don't drift, but fight back!

24...Rd8
[24...Rf2+ 25.Rxf2 exf2+ 26.Kxf2 Re4 27.Kg3! (27.c5 Na4 28.b3 Nb2 29.Rf1) 27...Rxc4 (27...Nxc4 28.Rf1 Re3+ 29.Kg2;

Lessons:

Don't panic! You must search for an answer to your opponent's threats. Juniors are sometimes very worried by opponent's king's-side attacks, and go into a hedgehog posture, and it's the posture that kills them. I sometimes say, oh, don't worry about that, they're only threatening mate.
Fight back! You must not drift when you are worse, you must fight a way to create problems, and think seriously about our opponent's counters.
