From deep blue log file: Nxe6 came from book trivially.

Nxe6 is a well known win. h6 is very poor simply. Of course all books say
'unclear' and only against Qe7 they say it is a clear loss for black. However
show me 1 GM that plays it.

Oh wait a minute, long before that match Kasparov-Deep Blue, didn't kasparov
co-author some books saying Nxe6 is a win for white?

Kasparov never plays caro-kann and the computer is so bad, it always exchanges
queens. See game before. So he simply didn't care going into a lost position. I
bet he didn't even mind losing the match too much. He didn't in fact as his
FIRST reaction showed at CNN minutes after losing. Only a few hours/day later
when he realized he would not get a rematch from the company he had served so
well, his reactions were furiously.
