A remarkable game by Rybka 3 Dynamic vs Rybka 2.3.2a

[M ANSARI]

I have been testing Rybka 3 Dynamic and although generally I feel it is a little weaker than the Defaul version ... it can come up with some spectacular brilliancies. Nick posted one on the Rybka forum that was quite impressive ... and here is another which was very interesting. Note that this was a very quick game (3 0) yet some of the combinations are quite deep! Try this game while running your favourite engine and see if it can come up with some of these moves. I am quite surprised at how different the evaluation of this version is compared to the default version. It seems like a completely different engine with a very very aggressive nature. Reminds me a lot of Deep Junior type of play but only a little stronger.

small tactic in its favour ... the Knight fork on c6 allows justification for
this risky pawn sacrifice. The idea is that this seemingly strong white bishop will end up having to be tied up protecting this tactic and will have to take pawn exchange with pawn and not bishop eventually0.49/13
