  the #1 spot after qualifying with twenty games, 20-0).  He has had
  mixed results in previous years tournaments, but recently elevated
  his game considerably.  He showed his fine form by tying for first

  win over two-time MSO gold medalist Fred Kok.

 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.

 In these games, Mona indicates a mate threat with a +2000 bonus, so
 a score of +4150 indicates a small positional advantage with a double
 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.
