It's probably pondering which made it possible to find the right move here. It
seems that Shredder had allocated a large time for its move (because of its
fail-low). I guess that Comet could profit from this.

On the other hand, when Comet detects a fail low, it allocates a lot time to
resolve it ( up to about 6 times the usual average time).
