It's the first time a customer complains because the product shows too much
respect! :)

Actually Tiger always expect his opponent to be a very tough one. After all, you
could have been Kasparov, Bronstein, or a multiheaded Junior or Fritz. Tiger
cannot be sure you are not one of these. So it decided to play it safe.

If you want it to be more agressive, you can do 2 things:

1) set the "score for a draw" to a reasonnable negative value. If you play
against it, -50 (half a pawn) is OK. Against other strong programs, -10 (a tenth
of a pawn) is more reasonnable. This setting is in "Extra->Options->Advanced".

2) In the same page, you can check the "Anti-human play" box. With this, Tiger
will avoid to fall into anticomputer strategies.


I'm glad to know you are now in the club of Tiger users! ;)
