like Uri i like to look to the games too and especially the number of
obvious bad moves made a game by the opponent of the computer. Taking that
into account junior achieved the best performance by a large margin so far.

However if you look to the lost games and also the positions that it didn't
manage to convert to a win (like 2 pawns up against khalifman and still
he draws) then there is still a lot to achieve.

Basically a very well rude statement of mine: "i can draw programs
at any time of the day, because i can convert to drawn endgames",
seems a very cool statement, and practically implemented a lot.

They however still don't seem to use a different statement of mine:
"just go out for a draw against the computer, you'll have your draw
then but most likely it will blow it somewhere giving you a chance to
win".

let's pray shredder plays a match against kaspy or kramnik real soon,
because that would be real cool. the program with the best endgame against
the best player(s).

However i think the message of Uri reflected clearly that knowledge
has become more important now, despite that he seemingly draws the wrong
conclusion.
