There is one hint that Joel Benjamin likes Nxe6 - since this move was not
calculated but in DB's opening book.   Although not certain, I suspect to leave
this move in the opening book - they very much like the way DB played this from
the white side. As someone else mentione - top GM's are not playing h6.  I read
(heard) somewhere that GK played h6 since Fritz never played Nxe6  against him.
Kudo's to the DB team for leaving this move in the book.  I suspect if GK
thought this move (Nxe6) was in the opening book, he never would have played h6.
 Do anyone believe GK would have played h6 against a top GM - not in my opinion.
 Another example of GK changing his game, and perhaps too much, because he was
playing a computer.  IMO, he would have much better and more interesting chess
if just played his usual game of attacking chess.  The New York Times (May 13th
1997) said "The Chess litature has warned against that particular error (7....
h6) since 1987 and everyone knows how to avoid it"
