> Come on fellas help me out I'm curious to see which engines play ...d5 Hook your beast up to this position.
None of my main pets play d5, and those that want to play it prefer to play Qc3+ first, are you sure that d5 is the best move?

Fritz 9 plays it.
The other ones I tested don't even have it in the top 5.
With regard to Vytron's question: I don't think anyone will be able to proove whether this is the best move or not. It might even be a defect of Rybka 2.99z that it plays this. I think a GM would have to think carefully about it - it makes the Bc8 bad and it's not totally clear how black is breaking through.

That's true but maybe the engine likes the fact that the king is slightly exposed but either way it looks like a human move to me relying on intuition more so.So I guess it's a HUMAN move.To me this is deep and shows the level to which this new Rybka is playing(it's not 3.0 yet)or maybe she was playing at a high contempt level,what you say Larry?

I am curious about your hardware. How do you like the Phenom? How is it performing against the Q6600's? Is it stable? Thanks in advance.
Well I have to say I am slightly disappointed.I should have gone with Intel Quad or Core 2 Duo even,however the price is good for Phenom Quad under $900.00US includes monitor lol,by the way I figured Mexico would come up with this move I did not try Mexico.
