Players

Six players registered. We welcomed a new player, JulieBot, a DCNN program by Katsuki Ohto. It first competed in the UEC Cup earlier in March.

Results

After five rounds, each pair of programs had played once. Zen19X had five wins, abakus four, AyaMC three, HiraBot two, and ManyFaces1 one.


ManyFaces1 vs JulieBot
Move 87

In round 6, after 87 moves, ManyFaces1 and JulieBot reached the position shown to the right (JulieBot is Black). It seemed to me that JulieBot was doing well – though I may be mistaken. But what was remarkable was that while ManyFaces1 had used 57 minutes, JulieBot had used only 71 seconds. If JulieBot can play this fast and reasonably well, I expect it will excel at blitz Go.
ManyFaces1 won convincingly. Over the whole game, it used three hours while JulieBot used five minutes. JulieBot can play so fast because it does no search.
