Ah, HAH. Then go and see the post, below, "Fritz6 and Winboard engines" that
says, according to Mogens Larsen, that the author of Gandalf has "worked
around" the problem. Very good. He could work around the problem because
he was aware of it.

***
Before Crafty became a "Native" CB engine, it also had its hashtables
cleared. And here is why Dr. Hyatt could not work around it: If memory
serves me, (I could be mistaken but I don't think so), Dr. Hyatt
DID NOT KNOW about the problem. According to him, (about two years ago
if I remember right), HE WAS NOT TOLD.
Nor was I.

Now you see that the tournament
posted in "Gandalf wins again" has "issues" that ARE relevant.
See, two? years later, it is still relevant.
