Gerd, I did the opposite lately. I started for example with a global array for
the PV. I changed it to a local array of search (long before I started to
program chess - this was done with my Kalah program). First tests seem to
indicate, that an explicit move stack is not faster, than having a local array
inside search. And the later looks cleaner to me. 512 (pseudo legal) moves will
certainly be enough. Probably 256. But then search might fail for illegal
positions (15 Qs for one side).

The explicit stacks might make an SMP engine more difficult?

Cheers,
Dieter
