Use the best move stored in your hash table for the root position. An
alternative is to use an approach suggested here by Fabien Letouzey on September
11th 2002, which can be found in this file from the archives:

My program uses MTD(f), and it uses the hash table to get the PV. I've not tried
the other method, although I intend to try it some day.
