YABRL: Ktulu 4.2 third behind the Ruffians

[Robert Allgeuer]

Geschrieben von: / Posted by: Robert Allgeuer at 17 January 2004 00:23:40:

It seems that Ktulu 4.2 is now in the absolute top group of free engines. After 634 unique games against all currently active engines it is ranked third, only topped by the Ruffians. At this stage it is of course not clear, whether Ktulu is a Blitz specialist like Delfi or Pepito or it is also that strong at longer time controls. In any case it has improved tremendously, more than 100 points compared to version 3.9. A pity that the author has no intention to release free successors to this version ...
For details on time control, conditions, platform etc. please see link below. Next engine will be Sos 4.

Agreed. Wonderful though, that he gave us the free stuff, isn't it?
Life is great for a Winboard chess engine fanatic like me.

Sure. Have sent them to your e-mail address. Even though I have zipped them it is still a _big_ e-mail, 5.5 MB, so if you have a modem it will taken some time ....

what I meant is that Ktulu with its extremely rapid progress would have been a real contender for the "crown" of the strongest free engine.
