This report is about incidents in the ongoing TCGA 19x19
Computer Go Tournament, now running on KGS. I am writing
this for the record, so that the players and organisers
will be aware of all the information that I have.
These statements are made for the record. I hope I can
be regarded as impartial. I am only making statements of
fact anyway.
__Incident 1.
During round 2, I removed 'ntnu' from the tournament, at
the request of its operator.
I hoped that this would reduce the length of the tournament
from 36 rounds to a more manageable 30, which would allow
it to end before the start of the July KGS tournament.
However, it seems that that is not how the scheduler for a
multiple-round-robin works. Round 10, with eight players,
has three games and two byes, rather than the four games
that one might expect. I assume that the entire schedule
was drawn up in advance, and one of the two "byes" was
scheduled as a game against the now-absent 'ntnu'.
I do not know how to avoid a clash with the schedule of the
KGS July bot tournament. I am now too tired to think
sensibly about it, and will go to bed soon. I will leave
'guxxan' to think about it.
__Incident 2.
During round 3, 'ajahuang' saw that Fuego19, which he was
operating, had a hopeless position against nomitan440, and
proposed logging in and resigning for it. If I had been more
alert, I would have realised what was likely to happen, and
told him not to; but I said nothing.
He logged in to Fuego19's account, and resigned for it. The
KGS tournament system observed a human using a bot's account
in a bot tournament, regarded this as an attempt to cheat, and
marked the game as lost by "Forfeit". Thus this round 2 game
has two different results: KGS sees it as lost by Fuego19 by
resignation, while the KGS tournament system sees it as lost
by Fuego19 by Forfeit.
There is no significant problem so far, this outcome was what
I had expected.
However, the tournament was running behind the optimistic
25-minutes-a-round specified when it was set up. So when this
round 2 game ended (all the other round 2 games had already
ended), round 3 began immediately. And ajahuang was still
logged in to Fuego19's account. So Fuego19's round 3 game
(against AyaMC5) was also treated, by the tournament system,
as lost by Fuego19, by Forfeit. But the game continued to
be played.
When the other round 3 games were finished, round 4 started
(the tournament system regarding the Fuego19/AyaMC5 game as
already decided). I realised that Fuego19 and AyaMC we still
playing in their round 3 game and had not joined their round
4 games, so, to free them up and let them play in round 4, I
used my admin power to "kill" this game. I believe that
Fuego19 had been winning it at the time. I killed it rather
too slowly, so that when AyaMC5 joined its round 4 game
against Zen19S, it has already lost one of its 15-second
overtime periods. I apologise to AyaMC5's operator for this.
Fuego19 did not suffer loss of an overtime period, as it had
a bye in round 4.
