IBM's "Deep Blue" computer can beat any human being, including a former world champion such as Gary Kasparov. Thus, it follows that Deep Blue must give a handicap to a human player in order for a human to have a chance of winning.
In games like golf, handicaps are relative to "par," that is, the number of strokes a "scratch" golfer would require to play a hole or a field. By definition, most players require a positive handicap relative to "par;" a few can get by with a negative handicap. In "Deep Blue's" case, all the handicaps would be positive.
Has Deep Blue, in fact, given such handicaps to humans (a pawn, piece, or more)? If so, what were the results? Can a handicapping system be constructed around how large a handicap a human player would need to beat "Deep Blue?"
