I don't!

9...Bg1 is a lemon. (Also 7..Kb8 would have been more "natural".)

One of the major points of Black's semi-fortress is to answer checks
on the c-file with Kb8, so 9... Kc7 is absolutely necessary.

That's why White has to discover Fischer's combination of Rb5 and Ka8
(preventing ...Kb8) followed by a check on the c-file.
