some facts:
1)The player's rating was more closer to 2200 then to 2100(the player was arlond
hasidovsky)
2)The same player drew also against Rebel and Deep Junior(Unfortunately he did
not play in the last round and this as the round when shredder played against
his team.
3)The player drew most of his games and drew also against humans with better
rating of 2300 and 2400.
I think that hasidovsky's style is leading often to a draw against players.

4)Being the strongest player against kramnik does not need to avoid a draw
against 2100 players.

A draw against 2100 players can be a result of games with no mistakes but doing
the position more complicate in order to cause kramnik to do mistakes is not
needed if the target of the program is not to lose the match against kramnik(not
losing against kramnik is a fantastic result for chess programs).

 Do you honestly believe
>that could EVER happen against Kramnik? I don't.

If the 2100 player could buy Kramnik and play at home against him then I suspect
that it can happen to kramnik.
