As far as I know, this interpretation is unwarranted by the facts. I
believe the final verdict is that objectively, 29...Bxh2? was a bad
move, one that turned a theoretical draw into a loss. Extensive
analysis by Olafsson and Timman, on pages 38-40 of "Fischer World
Champion" (New In Chess, 2002) demonstrates this. That Spassky later
erred, playing 36.a4 instead of 36.Kg4, does not change 29...Bxh2? from
a bad move to good. The path to a draw allowed by 36.a4 was as narrow
as a wasp's waist, and Fischer failed to find it, playing 39...f5?
instead of 39...e5, and so ultimately he lost.

If Fischer were a poker player, he could have been a great
one too. As they sat down to play, Bobby saw poker tells from Spassky.
He saw fear.

Highly debatable. Fischer himself said "I don't believe in
psychology, I believe in strong moves."

What would a genius do to strenghten Spassky's confidence and make the
entire match interesting? Bxh2!! and then game 2.

I would instead tend to agree with Edmondson's assessment that,
psychologically speaking, it was 11...Nh5 in game 3 that beat Spassky,
if such a thing can be attributed to any single move.
