just improve its tactics so the games will last
longer. The longer a game lasts, the more
opportunities there will be for the human to
go wrong. Let's say you got to where the
average game lasted 100 moves; I think by
that point, your program would be winning a
lot more games, due to stupid human errors.

Or due to the fact that few people, at 10 minutes per move by the
machine, would be willing to play a game that lasted 17 (immediate
response by the human) to 24 hours.
