I have also followed this discussion with interest, and one thing seems to pop
up everytime: People (of considerable strenght say 1900-2200) playing against
computers find it "easy" to draw them, but hardly ever win over them and
therefore they can achieve a relatively high rating against them, but when we
see the 2500-2800 (and above:) GM's play computers, they play to win from the
word go! only if the game dictates a draw they will settle (yes i saw Huebner v
Deep Fritz) with this in mind it is understandable, if i am right in my
observation, that computers could get a better performance in the company of
highranked GM's, since complications favors the comps, or so it seems.
In other words it appears to be fairly easy to draw a comp at will, alsmost
impossible, in comparison, to beat the comp at will and very easy to lose
unintentionally ;)
