Tim McGrew - Vishal Garg
D00 Blackmar-Diemer Gambit (boo...)
October 20, 2009

Notes by Mike Schulte

Tim McGrew and Vishal Garg decided to play a blindfold game. Anthony Shiver played out the moves on a board to keep both players honest, and I recorded the game and some of the players' more interesting comments.

1.d4 d5 2.e4??

Yes, I realize there is practical value to the Blackmar-Diemer Gambit. Still, I object on principle... and also because of my abysmal score against it.

2...c6

2...dxe4 3.Nc3 c6 is an alternative route from the Blackmar-Diemer Gambit to the Caro-Kann. I've played this many times as Black.

3.Nc3 dxe4 4.f3

This move is an attempt to stay within Blackmar-Diemer Gambit territory. Instead 4.Nxe4 leads to the main lines of the Caro-Kann. Tim can rarely be tempted into playing the main line of any opening!

4...e3

Vishal wisely declines the pawn. I don't know if returning the pawn like this is objectively good, but it strikes me as a reasonable practical choice against a McGrew. Usually, being a pawn up against any member of that family means you are losing, and probably soon!

5.Bxe3 Nf6 6.Bc4 Bf5 7.Nge2 e6

In many of these Caro-Kann lines where Black plays his bishop to f5, White will try to hunt the bishop down with pawn moves on the kingside. The present game is no exception.

8.g4 Bg6 9.Nf4

At this point, Tim commented that he was still in book. Vishal had been out of book since move two.

9...Bd6!?

White would be very happy if Black played ...h6 or ...h5 in the near future, since a subsequent Nxg6 would force an ugly recapture with the f-pawn. This bishop move at least gives Black a way of avoiding such a disaster.

10.h4 Bxf4 11.Bxf4 h5

This good move prevents White from gaining too much space on the kingside and gives the light-squared bishop some breathing room.

12.Qe2 Nbd7 13.g5 Nd5 14.Bxd5 cxd5 15.Nxd5

In a strange twist of fate, Tim is the one who ends up a pawn ahead, while Vishal has some compensation in the form of pressure on the c-file.

15...Rc8 16.Nc3 0-0 17.0-0?

17.Ne4 would keep Black's compensation to a minimum. 17.0-0-0 was the move Tim later wished he had played, although the king is a bit more exposed on the queenside. I wonder if both players were already forgetting about the bishop on g6. I had not forgotten, of course, since I was watching the game on a board!

17...Qb6 18.Ne4 Qxb2

Black has many tempting possibilities here. 18...Qxd4+ is also reasonable, while 18...e5 19.Bg3 exd4 20.Bf2 Qxb2 21.Rfb1 Qxc2 looks very pleasant for Black.

19.Rab1

At this point Vishal exclaimed "I knew I missed something!" I'm not sure what he meant, since he still has the better position.

19...Qxa2 20.Rfc1 Nb6?!

Black allows White to gain some dangerous chances against the advanced queen. 20...Qd5 or 20...Qa4 immediately would be better tries.

21.Rb3?! Rc6?!

Black is still better here, I think, but the silicon monster points out a better path. At this point Tim said "Mike, you can go back and give 17.0-0 a question mark." Here 21...Nd5 22.Be3 b6-+ is a stronger line, suggested by Fritz.

22.Qd1 Rfc8 23.c3!

With the queen on d1, White can play this advance. Now Black does need to worry about his queen being trapped.

23...Qa6 24.Ra1 Na4

Vishal calmly proclaimed "I think my position holds together here......maybe? (If nothing else, I think that knight move was forced.)"

Sorry, Vishal, but it wasn't even the best move! 24...Qc4 25.Nd6 Rxd6 26.Bxd6 Nd5 looks good for Black. In return for the exchange, Black has light-square strength and a strong knight on d5.

25.Nc5 Nxc5?

25...Rxc5 26.dxc5 Qc6 looks much better, with a solid position for Black. Again he has good compensation for the exchange.

26.Rxa6 Nxa6 27.Rxb7 Rxc3 28.Rxa7?!

Perhaps this is too greedy.

28...Nb4 29.Kg2 Rc2+ 30.Kg3 R2c4

30...Nd5!? is better.

31.Ra4 Nc2

31...Bc2!? looks good.

32.Rxc4 Rxc4 33.d5 exd5

Perhaps 33...Rd4!?

34.Qxd5 Rd4 35.Qa8+ Kh7 36.Qf8?

Tim pointed out later that Be5 would have set up Qf8 on the next move, and Black would be helpless to stop the threats.

Vishal resigned here. Perhaps this was premature, as the heavily reduced material might give Black some drawing chances. However, this was no doubt a very intense game and it's easy to forgive Vishal for resigning. Perhaps 36...Rd5, preventing the Be5 threat, puts up sufficient resistance. Then Vishal can bring his knight to f5 and it's hard to see how White makes progress.
