Of course, all of this is a very long way from stating that "Botvinnik accused Kan of giving away his opening preparation and he never recanted this statement, though Smyslov publicly denied it."I have a feeling that there may indeed exist some more strongly worded and explicit accounts of Botvinnik's suspicions of Kan, perhaps in Russian chess journals, but that's just guessing, and it doesn't help us any here.And again, the maddening thing about Soltis is that he does not footnote and list sources for his claims here. I really doubt Soltis just made all this up, but I don't like having to guess about it either.Anyways thomas you make a good point, no doubt about it and thanks for posting it.
