Thirteen players registered. HcBot is new to these events: it is a build of Fuego, modified by Michal Dvoracek.
Normally, when an odd number of players is registered, I remove IdiotBot (with its operator's approval), so as to make the number of players even and avoid byes. But one of the players registered, break19, was not present shortly before play started, and has been unreliable in the past, so I left all thirteen in the draw, intending to remove IdiotBot if break19 appeared, otherwise to remove break19.
In round 1, there was an exciting game, with a lot of fighting, between Manyfaces1 and Zen19 SGF. This may have been the best game of the tournament – as both players are stronger than me, I do not feel able to comment on it, but I recommend looking at it. Zen19 won. Jonathan Chetwynd (a British 3-dan player) writes
A very exciting game, I especially enjoyed and appreciated the significant number of tenuki played.
Both players appear weak on liberties and life and death, at least from this game file.
e.g. black 137, clearly there is a liberty race, and had this move been played at G2 black would lead 4/3.
Also in round 1, SimpleBot played very slowly against WeakBot50k. This was because
it was on its 9×9 settings. It became short of time early in the game and
began to play very badly, and lost. Its operator Aloril changed its settings before
the next round.
Break19 had not appeared by the end of round 1, so I removed it from the draw.
In its round 2 game with CzechBot SGF, ManyFaces1 played out a losing ladder. Normally it reads simple ladders correctly, I do not know what was wrong here. CzechBot won the game.
Also in round 2, AyaBot obtained a solidly won game against IdiotBot, and lost it on time while unnecessarily filling its own territory. This gave IdiotBot its second win of the tournament, and put it briefly in the lead (hcBot has a similar loss on time to IdiotBot in round 1).
In round 6, Zen19 lost its only game of the tournament, to CzechBot SGF.

In its round 9 game with SimpleBot
SGF, Aya again obtained a totally
won game and then lost it on time. The final 16 moves are shown to the right.
AyaMC was choosing its moves fast, but it was unable to make the required 25 moves
in 30 seconds because of lag between Japan and the U.S. It always ends its games by
converting all its terrritory to one-point eyes, though there is no need for this.
It lost several games in this tournament because of lag while it was filling its
own territory.
However, my reason for showing these moves from its game is my aesthetic feeling that
if it wants to convert its territory to one-point eyes, it ought to do it more
efficiently. In the position shown, it has just captured a 16-stone group. It could
have converted these 16 points of territory to nine one-point eyes in seven moves;
and if it had, and had then passed, it would have won this game. Instead, it used 8
moves so as to still leave an eight-point connected territory, and then ran out of time.
