Black won 15 games and White won 21.
Five players entered. I therefore added GNU Go, to make the numbers even.
In round 3, DolBaram suffered from lag and disconnects in its game with Zen19X, and lost on time. Its operator then moved it from its hardware to run on the Amazon cloud.
After round 5, Zen19X had won 5 games, DolBaram 4, AyaMC 3, ManyFaces1 2, NiceGo19N 1, and gnugo3pt8 0.
In round 6, DolBaram reached a very close endgame in its game with Zen19X, and lost on time while playing the final stone of its first "10 stones in 30 seconds" overtime period.
After round 11, Zen19X had won 11 games, DolBaram 8, AyaMC 7, ManyFaces1 4, NiceGo19N 3, and gnugo3pt8 0, each player having won all its games against lower-scoring players. This list of scores puts the second player's score close to that of the third, and the second-to-last's close to that of the third-to-last. This closeness does not reflect their relative strengths, but the way in which the KGS pairing algorithm makes the second player play more games against the first player than against the third (and the second-to-last more against the last than against the thrid-to-last). I believe the pairing algorithm is correct to do this in a Swiss tournament; but I caution tournament organisers about the use of the Swiss format, if the allocation of second prize is to be important.
In round 12, ManyFaces1 stopped playing when it had more than 10 of its original 15 minutes left on its clock, and lost on time to NiceGo19N, changing the final order.
MC-based Go-playing programs are perceived by humans as playing "high", as if trying to make central territory. This is particularly true of Zen, which is perceived as playing high even in its games with other MC-based programs.
