Now, it's no longer possible to confirm the hypothesis that you would have
accepted the result 11-9, but since you revealed the problem I think you would
have. My objection is that you conclude there is a problem on the basis of two
testsets. Even 20-0 for Crafty is possible, even though less probable.

It is still unclear to me, how you checked the results. If it isn't to much a
bother please explain how you checked the results. It can't just be the
comparison of game score, or?

You inadvertently proved that the probablity of a 12-8 win for Crafty isn't
zero.

No, that was very honest of you.
