 Pietro is an interesting character that I had the good fortune of
 meeting in London at the Mind Sport Olympiad -- he drew the seat
 next to mine in the Omaha poker tournament!  He won a gold medal in
 mini-bridge, bronze in Mastermind, and finished forth in three other
 events (Othello, Boku, and Settlers of Catan).  He is a very active
 LOA player on the PBeM server, and had a 14-2 record when this game
 was played.  This game is more tactical than some of the others, as
 Mona abandons the blockading strategy to take a piece in the center.

 A note on Mona's minimax scores:

 There is a significant odd-even effect, so odd-ply values are likely
 optimistic (at least 50 points too high, so +50 should be interpreted
 as an equal position).  A score of about +150 usually indicates a
 small advantage, and +300 a clear advantage.

 Mona indicates a mate threat with a +1000 bonus, so a score of +3150
 indicates a small positional advantage and a triple threat to connect.
 Only certain types of mate threats are detected statically, so there
 could be more in a given position.  Mona reserves 0 (zero) for a draw
 and +32000 for a win.
