Here are some postal games between the top-of-the-line Fidelity machine and some humans. The micro was set to a minimum depth of 8 ply and went up to 11 ply. The left column shows the final position in each game. In some of the games, the machine was forced to play openings not in book in order to get it into a game more suitable to its tactical style. There is a wide variation in the strength of the humans. Marshall and Passell are OTB experts.
