Even suppose the center groups were seki. In Japanese rule, the result was probably W+0.5. However, in Chinese rule, because black had one more stone (tengen) in the center, so the result was B+0.25 (Black: 180.75 = 180 (Points) + 2 (Shared) - 0.5 (Komi) / 2)
This concludes that Zen was losing in Chinese rule. > > I have seen in my own games several times, when Zen has blundered in >> late yose and have lost a won games.
