You are right.  The strange thing was that at that point Rybka had only two
moves in the book:  9.Rg1 marked in green and 9.h3 unmarked.  It HAD to play
9.Rg1 but didn't. There are many possible reasons for this.

Rybka was then again taken out of book at move 11.a3.  The inferior line (in my
book) had only 13.Rb8, but Shredder played Qb8 after almost four minutes of
pondering.  This further lead to the illogical Qe2 and the rest is known.

You are very perceptive, thanks.
