I think number of hands played is a crucial factor.

If the computer was tested by playing only 1000 hands against a line up of 1000 of the best players to make a total of 1,000,000 hands.- I think it would lose, because the human would be able to learn quicker over the small sample size.
If the computer started playing more that a few thousand hands against a single human it would be theoretically easier for the computer to make accurate predictions on the human. Then it may start to make very good decisions based on the complete recollection of all those hands.
