Subject: Deep Blue Overlooked Perpetual?

Author: Steve Schooler

My understanding is that in game 5 of the last (6 game) Kasparov vs Deep Blue
match, at one point:  Deep Blue was winning (or close to it); Deep Blue then
tactically blundered, which allowed Kasparov to achieve a perpetual; and
Kasparov overlooked it.

Is my understanding accurate?  If so, has anyone heard of an explanation for
this; I thought such a tactical blunder impossible?  In absence of IBM
explanation, the only speculation I can conjure is:

1.  human intervention
2.  flaw in search algorithm
3.  horizon effect

None of the above seem plausible, and no other explanation seems plausible.
