Thanks for the position Dom, it seems an interesting novelty from Fritz!

Zap!Chess thinks White has not enough compensation for the Knight, Hiarcs 11 likes Black even better it seems after 13. O-O than Zap.

Toga thinks that 13...Qb6 -the move that Fritz expected if I understand Chessbase notation correct- was possibly a bit better than 13... Qa5. But White seems to have enough compensation according to Toga, also after 13...Qb6, although Toga evaluates the position after 13. O-O not so high as Fritz did in the game.

Rybka sees an exchange plan and not a sacrifice, and the score is not very good:

After 20 plies Hiarcs thinks 13...Rc8 is the best way to go. What do other programs think? Will this line find its way into theory, will Fritz's move be played in Leiden in May or will it disappear?

Perhaps someone with multicore hardware can test it against Rybka

as black after 13th Move 0-0.

Thats why i like to test with 10 moves only for CCRL. Follow hydras example of 10move book. Let the computer come up with new ideas rather going thru the same path zzzz.

I have a quick match between Fritz 10 v Rybka 2.31 at the same time control to compare. Stay tuned!

[D]r2qkb1r/1b1n1pp1/p1p1pn1p/1p4N1/3P4/2NBPQ2/PP3PPP/R1B1K2R w KQkq - 0 1

After this position

Fritz 10 v Rybka 2.3LK 0-1
Fritz 10 v Rybka 2.31 0-1

Fritz 9 v Rybka 2.3LK 0-1
Fritz 9 Rybka 2.31 1/2-1/2

It seems Rybka pretty much put this sacrifice in the scrapheap

Perhaps next rybka 2.3LK Vs rybka 2.31...

I would suggest a Rybka verses Rybka experiment from the position after the sacrifice.

Rybka will also win the majority of the games from a neutral start, so it could also be possible that Rybka was simply outplaying the opponents.
