White connects the half point ko.

Diag.: Dead stones marked

After the dame have been filled the position should look something like this.

Captured stones:
B: 12
W: 16

With Japanese scoring:
B: 57+16+5=78
W: 57+12+2+5.5=76.5
-> B+1.5

With Chinese scoring:
B: 184
W: 177+5.5=182.5
->B+0.75


So, what's wrong? How does White win?
Thanks for suggestions.

BillSpight: Hmmm. Might the reported winner be a typo?

jvt: According to [ext] Jan van der Steen's web page Yang Jaeho won. But maybe he played Black, not White, and the two mistakes cancelled each other?
