Ten minutes went by!
But Peter was still not making any moves!
With both parties allocated two hours of game time, Peter only had an hour and forty-five minutes left on its timer. A precious dozen minutes had been wasted on just this one move!
The two referees gave each other baffled looks.
The Americans were unable to sit still any longer. They kept looking in the direction of the machine, afraid that there was some bug with the code that led to Peter freezing up. But when they checked the machine's status lights, they found nothing wrong with it, nor was there an error. This showed that Peter was working normally and that it was just "thinking." Further, it was "deep in the tank."
Why?
What the hell was going on?
Why did it just stop making moves?
No one could understand what Peter's hesitation was!
