The numbers in these tables do not add up as you might expect. This is because a player that does not show up for a round still received half a point for the "bye", while its opponent received a full point. | |||||||||||||||||||||||||||||||||||||||||||||||||||
Juho Pennanen's Roverandom, which had registered for the October tournament but too
late to be entered, played for the first time in both divisions of this tournament.
Fuego9 beat valkyria three times and lost to it once; beat Rover01 four times; and beat break three times. Valkyria beat Rover01 four times and break twice. Rover01 beat break twice.
The other five games were non-appearances by break. Under the scoring system in use for this tournament (but not for previous tournaments), break received half a point for each of these games, while its opponents received full points. I was aware when I set up the tournament that this might happen, and would not be ideal. I chose this way of setting up the tournament to avoid the situation in which there is an odd number of players in a division, one of them necessarily receives a bye, and a different one, not its opponent, fails to show up, thereby leaving two other players with no game.
The most interesting game was between Fuego9 and valkyria, in round 4.SGF. This as it happens was Fuego's only loss. A ko fight developed, and was fought competently by both players.
The new player Rover distinguished itself by winning all its games against Aloril's three bots. I am as always grateful to Aloril for providing these bots, and in particular for giving me the option of dropping one of them to make the numbers even and avoid byes.
