Hi folks,

Karjakin,Sergey (2660) - Anand,V (2792) [B90]
Corus A Wijk aan Zee NED (1), 14.01.2006
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 Be7 9.Qd2
0-0 10.0-0-0 Nbd7 11.g4 b5 12.g5 b4 13.Ne2 Ne8 14.f4 a5 15.f5 a4 16.Nbd4 exd4
17.Nxd4 b3 18.Kb1 bxc2+ 19.Nxc2 Bb3 20.axb3 axb3 21.Na3 Ne5 22.h4 Ra5 23.Qc3N.
Karjakin deviates from Leko-Vallejo in Monte Carlo 2005, where 23.Qe2 was played
and the game ended in a draw after 67 moves. But Anand is prepared: 23...Qa8
24.Bg2.

24...Nc7!

On my computer (AMD 64 X2 4600+)
Programs find the move in :
- Fritz 9 doesnt find the move after more than 2 hours
- Rybka 101 Beta 10d finds the move 24...Nc7 after 26min 25s
- Fruit 2.2.1 finds the move after 17min 22s
- Deep Shredder 9 using the dual core finds the move after 5min 45s

Was just interesting for me to see how difficult is the move to find for the top
programs on high speed computer.

Best regards to all
