I am trying to do the statistics for the odds of computers drawing against GM of
this level....

For instance, the GM are (to make it even) 2600, and the computers, if they are
barely GM strength, are 2500. What is the winning percentage? Each GM has a
winning chance of 64% (100 point rating dif), but in *four* of the five games,
the GMs had black, and black only has a 40% chance against white with even
players! If two players who are even in chess skill play a match with one always
white, the 'white' player would be just under 100 points higher rated
officially, even though in skill they are equal!

I wonder what the odds are that the computers would win >=50% of the games...
I'll bet that it is greater than 35%, which means that the GMs could still be
100 points higher than the comptuers and one third of the time have a result
like this!
