Too late ? You must be joking. Black could play it any time in the next 15
moves.

I don't understand this fixation on f5. What's wrong with any other pawn advance
? Black can play h5, g5, f5, and take it from there, any time during the game.
What is white going to do about it ?

I think this game was a low swindle by Kasparov. He played a dubious line based
on preparation that showed Fritz will not punish him for it. He gave Fritz about
20 free tempi (5 moves to capture the pawn, 5 to disentangle, 5 to move his king
and 5 to break).

This was not anti-computer strategy. Kasparov played computer strategy! Locking
the position with a horribly cramped reverse chain, taking a worthless pawn and
hoping the sky will not fall on its head is just what a computer is expected to
do.
