Interesting Move in the French

Post by AdminX » Thu Feb 21, 2008 10:11 am

I was reading on the Rybka Forum, where I saw this interesting move (10.Nxd5) played by Rybka in a sideline of the French opening.

See: ... id=3276#fp

Searching my Megabase 2008 I could only find two games played from the position above, one played in 1975 and the other in 1991. Below is the latter of the two:

[Event "Vrnjacka Banja"]

However the poster Nelson Hernandez states that it was played in a game Tatang-Blinkers88, in 27 Apr 2006, by Rybka 1.1 vs. Toga II 1.2 Beta2a. Does anyone have a copy of this game? I would like to add it to my database. I also found it interesting that not too many engines see this move. Is it the strongest move or just a very complex one for Black to deal with? Some engines like Crafty 20.14 w32 see it but drop it and prefer other moves.

Postion after 10.Nxd5!

Toga II 1.4 Beta5c switches between Nxd5 and Ne2 multiple times on my system, and was choosing Nxd5 when I stopped the analysis. Since black quickly loses a bishop in return it's not hard for engines to see this is a good move, even if most don't see it as the best.
