|time||Three hours each, sudden death|
The first round started at 22:00 UTC on September 8th
In the table above,
Black won 7 games and White won 11.
Five players registered for the tournament. I therefore added GNU Go, for the same reasons as in the August tournament.
The format, Swiss with six players and five rounds, was unfortunate. The players played each opponent once (producing entirely consistent results, with no intransitivities); then there was a final round, in which the second-best player, AyaMC, played its second game against the best player, Zen19S. This resulting in the third-best player, pachi, achieving as many wins as AyaMC, and (as it worked out) as many "annual points". To avoid such outcomes, a Swiss tournament with an even number of players should not have the same number of rounds and players (and one with an odd number of players should not have one more rounds than players).
Howver, I specify the formats of these events in advance, and only learn the number of players shortly before play starts. So I cannot avoid such outcomes.
In round 5, the game between Zen19S and AyaMC attracted 50 kibitzers at one time. Some of them said complimentary things about the level of play.
When I announced this tournament, I said that it might be the last Slow tournament on KGS. I thought there was little purpose in having slow tournaments, now that it is easy to hire multiple processors in the cloud.
However three people emailed me, urging me to continue running them. I had failed to appreciate the differences between designing a program to run on a cluster, and to run for longer on a single system. I will continue to run Slow bot tournaments on KGS, probably twice a year. I will schedule them to run for longer than the 36 hours that this one ran for.
