30 ODCCC Leiden (4), 27.11.2010

1.d4 f5 2.g3 Nf6 3.Bg2 g6 4.Nf3 Bg7 5.c4 0-0 6.0-0 d6 7.Nc3 e6 8.Qc2 Nc6 9.Rd1 Qe7 10.a3 a5 11.Be3 Nd8 12.Ra2
800 processors, and the move is Ra2?

12...b6 13.Ng5 Bb7 14.Bxb7 Nxb7 15.h3 a4!
This sacrifice is typical of the top engines, and frees the a5 square for either the knight, or rook depending on Black's reply.

16.Nxa4 Nh5 17.Kh2 e5 18.dxe5 Bxe5 19.Nf3 f4 20.gxf4 Bxf4+ 21.Bxf4 Nxf4 22.Nc3 Qe6 23.Ng1

When attacking, make sure everyone is invited to the party, and Rybka doesn't need to be told twice.

24.Qe4 Re5
Avoiding the exchange and decoying the queen away from its king.

[Trying to stay around the king to defend with 25.Qf3? Nxe2 26.Qg2 Ref5 27.Rf1 fails spectacularly to 27...Rxf2!! 28.Rxf2 Qe5+ 29.Kh1 Ng3+ 30.Kh2 Ne4+ 31.Kh1 Nxf2+ ]

25...Rh5 26.Qe4

26...Rxh3+! 27.Nxh3 Qxh3+ 28.Kg1 Rf5!
Threatening Rg5+

29.Rd5 Nxd5 30.Qe8+ Kg7 31.Qd7+ Kh6 32.Qxf5
The only way to prevent an immediate mate, but of course White is lost.

32...Qxf5 33.cxd5 Qg5+ 34.Kh2 Qd2 0-1
