Is it playing a move on the board ? If so this is a "Automated chess player playing a move". OF course it is your time and your testing methodology, but it is not your engine. And the author of this engine feel his engine should not be tested with this handicap. So you have 3 choices: - You test Crafty as Robert feel it should - You test Crafty as you want it to be and called it something like "Crafty with non official Book" - You don't care at all about what the engine's author want.
