 Antonio is one of the most active players on the server, and was the
 first to re-acquire an estabilshed rating after the recent crash, with
 a 17-5 record.  In this game he built up a nice wall on the left side,
 and was ready to flow quickly toward the top group.  Mona was able to
 interfere with this plan by blockading along the top, and won by being
 a little quicker to connect her pieces 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.
