Excluding forfeited games, Black won 11 games, White won 13 games, and there were 0 jigoes.
Five players registered. The organiser added gnugo3pt8 to make the numbers even and avoid byes.
The round 2 game between abakus and Zen19S was interesting. Most observers thought that Zen19S was winning, but overplayed. Abakus won. As both players were probably stronger than any of the observers, and certainly much stronger than me, I will make no comments.
|NiceGo19N vs Abakus|
|Moves 72-97. Move 98 captures at 74.|
In the round 4 game between NiceGo19N and abakus, abakus misread a ladder, as shown to the right. Its loss was large, and it lost the game.
|Zen19S vs Abakus|
In the round 6 game between Zen19S and abakus, Zen19S played a poor move on the 1-line, as shown to the left. This may have a similar explanation to a poor move it made in the previous Slow KGS bot tournament, which was explained as possibly caused by an integer overflow.
|AyaMC vs Abakus|
In the round 7 game between AyaMC and abakus, abakus played moves 81 and 83 as shown to the right. To even a weak human player, these are clearly bad moves: when White answers with the obvious 82 and 84, White is still winning the semeai, Black has two more dead stones, and White has some useful outside strength. And, I believe, this analysis is correct. This puzzles me. I realise that an MC/UCT program like abakus does not count liberties the way I do, but I have observed that its middle game is usually very strong: it not only "outreads" me, it "outreads" Zen. And I don't see anything in this position, such as seki or multiple ko, that might confuse it.
Also in round 7, gnugo3pt8 lost on time after the computer it was running on suffered an electricity outage.
In round 8, abakus got its revenge on NiceGo19N, with NiceGo19N misreading a ladder this time.
