A GM meets the BDG

It's always interesting to see how a grandmaster reacts to a BDG, especially since we get to see so few of such games. Here's one from last week's This Week in Chess. Black is Petr Velicka, a 41 year old GM from the Czech Republic. His opponent is an untitled player almost 400 rating points below him.

Schmid,Pab (2095) - Velicka,P (2464)
5th Open Vandoeuvre les Nancy FRA (7), 29.12.2008
BDG, Teichmann Defense

1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 exf3 5.Nxf3 Bg4 6.h3 Bxf3 7.Qxf3 c6 8.g4

This line is known as the Seidel-Hall Attack. I always like to see if a strong player will take the d-pawn. Black can do so and survive, but the GM doesn't risk it.

8...h6 9.Be3 e6 10.Bd3 Bb4 11.0-0 Qe7 12.a3 Bd6 13.b4 a6 14.Na4 Nbd7 15.Nc5 Rb8 16.Rae1 Bc7 17.Re2 Qd6 18.Rg2 Nxc5 19.bxc5 Qe7 20.Bd2 Qd7 21.c3 Nh7

After some maneuvering White come out of the opening in pretty good shape (for a BDG player). Black can't castle long, and would be going into danger on the Kingside. Rybka thinks White has the advantage here.


Rybka likes the line 22.g5!? Nxg5 (22...g6 23.gxh6; 22...hxg5 23.Qh5 are okay for White) 23.Qh5 Rf8 24.h4 Nh3+ 25.Kh1 b6+- (25...Qd5) 26.cxb6 27.Qf3 Ng5 28.hxg5 hxg5 29.Bxg5+-

22...f6 23.Re2 Nf8 24.Rfe1 Kf7 25.Bc4 Re8

26.d5 cxd5 27.Bxd5 Qb5 28.c6 Qc5+ 29.Kh1 bxc6 30.Bxc6 Rd8 31.Bc1 Ng6 32.Bb7 Ne5 33.Qe3 Qc4 34.Be4 Rd7 35.Bb1 Rhd8 36.Ba2 Qc6+ 37.Qe4 Qxc3 38.Re3 Rd3 39.Rxd3 Rxd3 0-1
