I am always interested in playing over your tournament games. It is nice
that you include the time control and machines used in your PGN headers.
I have some comments on two of the game.
This game of Comet A96 vs Phalanx I believe is a must for everyone to play over.
For me it was an extremely fun and interesting game to watch beginning
with the fireworks started by Black's Rc3. I thought wow, what a surprising move
for a computer to play. Could this program have calculated this line to a
positive eval through a deep search or does the program give pluses for
blasting open the King's position? I thought as I continued to play that whether
the move was coldly calculated or speculative that white was busted. Comet,
as most programs today, did not buckle under the preasure and mounted a brave
defense. And then the tide of the game turns to Comet's favour - the
curse of the passed pawn strikes again!
An very enjoyable game - like a rollercoaster ride. Nice job to both
of these programmers.

I was curious as how the program came to play this move. Other moves like
Bh3 or Qe5 give black a clear win. Rxg1 seems to throw away a nicely built up
wining position.
