Tiger searched for more time but did not search more moves because it used slow
pentium and no permanent brain.

Tiger on slow pentium cannot see 375000 nodes in a second.

The 1.5M vs 375,000 advantage is after considering the fact that deep blue
Junior used 3/4 second and tiger used more time.

I also read that deep blue Junior used more time when it failed low so the 3/4
second for each move may be wrong.
