I see from Nelson's icca article that you had been using 40 bits, and he
intimated that it should or would be expanded to 64.  I assume that was
due to memory limits.  Is there a correlation between hashkey and index
size?  That is, if I go to 40 or 64 bits, is the optimum overall table
size affected?

My results are unpredictable, something is causing wrong move selection.
 I posted the logic and the pseudo-code in the hope that perhaps someone
could see a flaw in my understanding of the process.

Since the process seems clear enough, however, I guess it's just a
question of some creative time with the debugger :-<
