Subject: Hash Table: Different moves with different table sizes??

Author: Brian Richardson

Looking for suggestions with a hash table "problem".  Running

8/8/7k/8/4p1K1/8/5P2/8 b - - bm e3; id "Fine position 16";

Tinker likes e3 with some hash table sizes (usually at around ply 16), but Kg6
at other sizes.  Even stranger is that e3 is picked at some smaller hash sizes,
and with very large sizes, but not for "medium" size hash tables.

Of course, I may just have a _nasty_ bug in my hash table code.

Or, it may be something subtle.  It _may_ have something to do with move
ordering--if there are two branches that happen to have the same score at the
same depth, in one case one position is hashed and it never "sees" the other
one?

Have others run into this?

Any suggestions welcomed.
Thanks.
