This system's performance was very difficult to measure experimentally.
It would be difficult to design and execute a test that accurately
measured the system's overall ability.
Instead, system effectiveness was informally measured by a series of
matches against opponents of varying strength. Of the human opponents
against which the system played complete games, it recorded 4 victories
and 2 defeats. Again, these players very from a variety of skill levels.
The system was consistently defeated by its only computer opponent: the
Free Software Foundation's GNUChess.
The most highly-publicized game was a match against Taylor University
philosophy professor Jim Spiegel. In a well-fought game, Machbanai was
defeated in a rook-rook-bishop-pawn combination. In his commentary on
the game, Dr. Spiegel, recognized on campus as a very strong player,
rated the robot's performance as "about average" among the opponents he's
faced.
