This is probably NOT the optimum. In general, the longer the average thinking
time for the engine to make a move, the larger the hash table should be. 32MB
should be more than enough for all games, unless you are planning on also doing
lengthy analysis.

Also, the manual is misleading in this regard. Making the hash table larger can
certainly speed up the search, which can then make the program play a little
better. It will not necessarily make the program "play faster".

And, actually, I think the default for the Chessmaster personality is 4MB.
