Subject: John, would you tell me how long it takes CM to see Nxh6

Very good play by CM.
Very interesting game to follow with Shredder.
I cannot get the Shredder book to play 1...e5 with tournament book selected.
Only will play 1...c5.
c5 89.8%
e5 10.1%
other than this one move, my Shredder 7.04 will make all other moves.

in this position, CM has set up a King side attack that Shredder does not see.
CM plays 22.Rg3. Now all of whites pieces are bearing down on black king, black
has several pieces out of play. This is an example of why some openings should
not be in book, with these book moves Shredder has been reduced to a loosing
position.
