Fourteen players registered, and all fourteen played in every round.
We welcomed a new player, kiaibot, by Matthew Woodcraft. It uses MCTS with very light playouts.
I apologise to all the entrants. I announced the time limits as "Canadian Overtime of 10 moves in 30 seconds", I stated them like that at http://www.weddslist.com/kgs/future.html, and I intended to set them like that. However I in fact set them to Canadian overtime of 25 moves in 30 seconds, a setting which I know causes players in East Asia to lose on time because of lag, however fast they play their moves. I only realised my mistake when it was pointed out after the tournament had started.
Some players, including kiseki, suffered losses on time through my mistake.

In round 2, EricaBot obtained a won game against SimpleBot, and began rapidly filling its own teritory and removing its opponent's dead stones. But, with 19 seconds left for six moves (which should not have been a problem for it) it stopped responding, and lost on time.

| Zen13 vs ManyFaces1 |
| After consecutive passes. |
In round 5, pachi beat Zen13 by killing a group which (I think) should have lived in the top right, and saving a group which (I think) should have died in the bottom left SGF.
In round 6 WeakBot50k and kiaibot handled a clean-up phase correctly. Throughout
the tournament, I was impressed by the behaviour of kiaibot. It consistently made legal
moves well within the time limit; it resigned whenever it had clearly lost; it
consistently beat IdiotBot, WeakBot50k, break13, and even SimpleBot; and it always handled
the game end, including any clean-up, rapidly and correctly. Admittedly its moves were not
great; but as director of these events, I am more impressed by good behaviour than by good
moves.

In round 7, kiseki timed out in a won position against WeakBot50k, during the clean-up
phase and while in overtime.

| Orego vs PNUGo |
| Move 39. |
In round 13, break13 made one move normally, and played no more moves until it had only one second of main time left. Then it started to play again, but lost on time. It showed similar but less extreme misuse of time in the next two rounds.
At the start of round 15, Zen13 and ManyFaces1 were tied for first place, each on 11 wins. They were drawn against each other, in a game which would decide the winner of the tournament SGF. Zen 13 won.
Also in round 15, kiseki again lost on time in a won position, while in overtime during the clean-up phase.
