Yes, you misunderstood. Quote from

"The match will be done like older FIDE world championship matches - the first
one to win 6 games wins the match, draws won't count."

Baguio 1978 for example was won by Karpov against Kortchnoi 6:5 with 21 draws -
I use the same system here. We won't get a statistically significant result - my
life (and holidays) are much too short for that :).

First, thanks for the info on the booklearner. You should add this to Crafty's
README IMHO - I think some users will be interested very much.

Here it doesn't matter much what I personally like as my task simply was to
setup both programs in an optimal way according to their producers/authors.
Personally I dislike all kind of booklearners btw.

But I really can't understand how you can say that Crafty likes variety against
computers - with default settings it certainly has the narrowest book against
computers from all engines I have ever seen. And I really think this is a very
bad idea as partially also shown in this match. Thank good that even the 3%
moves sometimes show up eventually - it might save Crafty's head in this match
;).

All the best,
Peter
