Dear Taylor,
I am just wondering why you do not know about the existence of
Averbakh?s letter to FIDE at ChessCafe.

I make no claims to omniscience, about chess history or anything else.
One has only so much time, and cannot read everything.

How can anyone trust any views and opinions of Averbakh on
chess history or anything?

Without knowing the full circumstances surrounding the letter in
question, I cannot make any judgement about Averbakh's part in it. As
far as trusting his view and opinions, as with anything else the
careful historian must weigh them against known facts and others'
testimony.
