There is no difference in playing strength/style/quality between the 3.12 and
3.12c versions (and the versions in between them, obviously). However, 3.12d
does improve blitz/bullet play under certain circumstances, specifically when
using a very large hash table.

The King clears its hash table on every move. In my testing with 3.12c on a
PIII-600, it took about 1/3 to 1/2 second to clear a 32MB hash table. This is
not significant during standard play, but losing 1/2 second per move in bullet
is costly. The King 3.12d drastically improved the method in which the hash
table is cleared, so this no longer becomes a problem. However, once again, this
was only a problem if a large hash table was being used in a fast game.
