Subject: Pawn Hash Tables -- Thank you Dr. Hyatt!

Hello Dr. Hyatt,

I just wanted to report that adding pawn hash tables to the Gothic Chess program
results in a noticeable speedup of the search! This was such a great idea! I
used 25% of the hash table memory for the pawns (color independent) and it works
great!

Interesting that the main hash table reduces the size of the game tree very
well, and pawn hash tables (imagine the payoff for my board with 20 pawns)
functionally speed up the search.

Thanks again!
