 Yngvi:  This game was one of those highly dynamic positions that can
 go either way.  YL had strong control of the board and was up material,
 but MIA was threatening to connect with its few pieces.  YL liked its
 position throughout most of the game but, eventually, YL wasn't able
 to answer the threats anymore and game-over.

 Both of MIA's wins were very convincing -- nothing like the lucky wins
 it scored in London last year.

  MIA plays e1-e4

 Darse:  Both YL and Mona give this move a significantly lower score than
 the suggested alternatives (c1-c4 or d8-b6).  Mona's score for White now
 jumps by about 150 points.  MIA is willing to sacrifice this piece due
 to its center-of-gravity metric, hoping to gain an edge in the race to
 connect.  This is probably a worthwhile gamble in an inferior position,
 but may be needlessly risky in a nearly equal position.

  MIA plays c1-d2

 Darse:  Offering another sacrifice to reduce the number of outliers and
 hopefully make the attack faster.  The scores increase in YL's favour
 again, but the position is actually getting more dangerous, tactically.
 The initial gambit was risky, but the additional sacrifices probably
 improve MIA's chances of success.

  YL plays h3:d3

 Darse:  Another 90 point jump for White, according to Mona, but Black is
 developing a dangerous position with only two outliers to connect to the
 main group.  It is difficult to properly assess this kind of position,
 but squeezing too hard will often allow the opponent to slip between the
 fingers...  If there is no viable alternative to this capture, then YL
 may have played into a line that gives Black too much play.

 In other words, MIA is playing a sacrificial attack that the evaluation
 functions of Mona and YL do not understand very well.  Black may have a
 better (or won) position at this point, regardless of what the evaluation
 scores suggest.

 the position is now being revealed -- Black has a dangerous attack.

 Darse:  There are guaranteed threats on the horizon, but Black's position
 is otherwise weak.  The outcome in this type of situation is usually a
 coin-flip.  If the threats peter out, the strong side will normally win.

 having to be made to avoid mate.  That does not mean all is lost, however.

 Darse:  It appears that the alternative defence 15... d6-a3 may survive
 the attack.  For example, 16. b5:d3 h2-e5 and the threats run out after
 17. d3-c4 h5-f5.  16... h1-e4 may also be sufficient, according to game
 roll-outs with Mona and YL.  White is able to seal off the Black pieces
 in the corner, permanently stopping the connection threats.

  MIA plays a7:a4

 Darse:  On this and on several other moves, MIA fails to play the shortest
 mate.  MIA also allowed shorter mating sequences than necessary in other
 games.  These slips are apparently due to the new proof number search.
 Positions are proven as a win or a loss (efficiently), but the new code
 does not ensure that the shortest win or longest loss will be played.
 Mark will probably patch this in the future.
