I do not see a proof that it was planned and designed.

The problem was not 7...h6 but the rest of the game.
I expect a player who designed that move to play better in the rest of the game.

I do not trust a quote from an unknown international master in kasparov's camp.

I am not sure if kasparov said that he regret the decision to play 7...h6 but
even in that case it does not prove nothing.

regreting the decision does not mean that he was prepared for Nxe6.
I see other possible explanations:

1)Every choice of a human in a game can be described as a decision
2)Maybe kasparov thought that Deeper blue was out of book before Nxe6(maybe
because deeper blue used time for the previous move) so he did not believe that
deeper blue is going to play Nxe6.

Kasparov could prepare h6 Nxe6 for the match but in that case I could expect him
to be ready to play immediately every known position in human-human games.

I remember that kasparov started to think when the position was still taken from
human-human games and this is the reason that I do not think that he was
prepared to play it.
