I thought it was "out" of a certain tournament, and unable to win.
But now that I open the link, I see it is a new program.
I'd be very interested to see how it does, even on a single proccessor.
I'd like to know if its playing strength is not too much below Rybka, that its other features make it REALLY WORTH 98 euros.

I mean, which program is the REAL candidate to be number 2 (if Rybka remains no.1)?
For that price, it needs strength as well. ie competitiveness against Rybka.


And regarding all other features, Is it no. 1 for features and chess experience enhancing (including entertaining and interactive, even on weak computer and even without internet) features?

Dear gents,

You'd think that for marketing purposes, ChessBase would pick a position where Deep Fritz 11 finds the best move as fast or faster than Rybka. But the evidence here shows that Rybka 3 is faster.

Surely, such positions exist...or do they?

All the best,
Steve

Maybe this is one Stephen, bm Ka1. Do not have Deep Fritz 11.

According to the article Deep Fritz 11 is not simply a multi-threaded version of Fritz 11, it claims that it has deeper chess knowledge. At CEGT blitz, DF11 on single CPU is 6 elo higher than Fritz 11.

At CEGT blitz, DF11 on single CPU is 6 elo higher than Fritz 11.

It was known beforehand that the Deep Fritz engine is different and stronger than its non deep counterpart, however, I expected at least 30 elo of difference. If DF11 isn't reported to have a better playing style than F11 I'll better go with Sjeng 3WC or Naum 4.
