Black won 10 games and White won 6.
Only three players, Zen19S, AyaMC and NiceGo19N registered. CrazyStone did not register becasue it was preparing for the 7th UEC Cup, to be played in Tokyo on March 15-16. I see that many other strong programs, including DolBaram, Fuego and Nomitan will also be playing in the UEC Cup. In future years I will plan to avoid such clashes.
To make the numbers even and avoid byes, I included GNU Go, running on a single processor.
|NiceGo10N vs AyaMC|
|Moves 39 and 401|
In round 1, AyaMC, playing black against NiceGo19N, played move 39 as shown to the right. This surprised me, a move at S10 looks better. Several onlookers also criticised move 40. However it is good enough to win the semeai on the right edge. AyaMC went on to win this game.
|NiceGo10N vs Zen19S|
In round 3, NiceGo19N played white against Zen19S. For move 80,
I had expected it to play at 82, aiming to kill a black group and save
a white group in ko. However it played elsewhere first. Then, for move
84, I expected it to follow up its move 82 by playing at 86; again, it
played elsewhere first. Then, for move 90, I expected it to follow up
its move 89 by playing at 100; instead, it first played five moves
I found it surprising that White was not quicker to start this large ko, and that Black was not quicker to play a defensive move to win the semeai without ko. Onlookers discussed the issue: one view was that Black was going to win the ko anyway, and so had little need for a defensive move; another was that White was going to win the game anyway, and could afford to play as it did. In fact, White won the ko fight and lost the game.
In round 3, Zen suffered its only
to AyaMC. AyaMC's creator, Hiroshi Yamashita, remaked that this is Aya's
only win against Zen in the last four years. Zen 19S's operator Hideki
Kato wrote, "The game was so complicated and exciting. Aya overtook Zen
at the L&D of Zen's huge group at right side and killed it. The game,
however, was not over yet. Zen tried to reverse many times but failed,
and Aya eventually won the game."
