This does not tell me how many draws were in the next 8 or 9 games so this does not tell me which program is leading. It did not take >Fritz too long to figure him out.

Rybka never even considered what was coming in any of his lines. Maybe Rybka had a winning position and it did not search deep enough. Without posting the game we cannot know if the 3.25 of Rybka was wrong evaluation or it did not win because of a different problem. It >has been my experience that does not bode well for a program in the long run. My >thinking is they have a very strong program here, not quite up to the level of >Toga, Fritz and Fruit yet. based on other results that I see it seems that Rybka is better engine than Fruit or Toga. Fruit or Toga have no book learning. I also think that it is wrong to decide based on games against one opponent. I remember that in Sarah's results the only match that Rybka 32 bit lost was against Fritz but it beated fruit and Toga in her matches. Uri
