Wael, look at the results, Baron was able to draw Rybka.

[Uri Blass]

Wael, look at the results, Baron was able to draw Rybka.

only by cutting it's connection to the internet so rybka had to use slower hardware and could not use tablebases in the endgame.

Rybka blundered by 69...a3 when 69...Kg2 is better.

If the same had happened to Baron, you would have said something else.

I do not know what I world say in different case.
This is not that I am against the baron but simply that it is important to mention the bad luck of rybka that helped the baron.

Here is some analysis by rybka2.3.1 without tablebases.

[M ANSARI]

Yes, Vas confirmed that the draw with Baron was due to lack of Tablebases. It was apparently giving problems with the GUI ... but that now TB would be "hardwired in".

[Erik Roggenburg]

Stuff like this happens in short tournaments and single games, so that's why they play 'em even though one of the engines is clearly the strongest!

Technical difficulties, bugs, operator error, etc.
