There is a huge difference between a Rybka - Junior basement match and a real match with opening prep and unlimited hardware.

Tell me about it Mischa. Really Big Difference.

Watching this game I thought it was funny to see how Rybka had offered the trade of queens at different points in the game and when Rybka finally had the queens traded off if was to Juniors advantage.

No proof for a huge difference.

In a single game rybka can lose and it is not a rare event.

Looks simply like a bad trade to me which could have been avoided earlier. Two minor pieces are better than a rook and two immobile pawns.

1. The Rybka team has one of the best book cooker of the world
2. Rybkas scaling is very bad on more then 4 CPU's

So, your statement is pointless.

Yes, that seems to be the trick with 23.e5 or with the variation leading to it. But can it have been a book preparation? It would be interesting to know what the last book moves were, each. In my databases, I find only one GM example for Rybka's 15...c6, and none for 16.Nb3.

I know that special tournament books are used in such events. For comparison, in the public RybkaII.ctg book, 15...c6 is set to red (unplayable, 0%), and 15...g6 or 15...Nb6 would have been played from it.

Some people connect this loss to a general underperformance of Rybka in the closed Ruy Lopez they observe... But here, it looks like the full point may go to the Junior engine (and the hardware difference). Although, if it was a deep preparation against the rare(?) 15...c6, it would be a good book win either.

(I don't know if 15...c6 is a new fashion among top GM, or in recent freestyle games; in that case I could imagine that it was not unexpected.)

[Tony Thomas]

Rybka is still going to win the tournament.
