Under area scoring (as with the SST rules, which were in use) White wins by 2½ points.
Under territory scoring Black wins by 1½ points.
My count is slightly different from the official one. No doubt I have miscounted. My conclusion is the same: White wins by area rules, Black wins by territory (Japanese) rules.
Some uninformed comments: the rulesThe game was played under area rules (SST).
The play in the yose suggests that the players thought they were using territory rules.
A move played under area rules is worth one more point than if played under territory rules, when compared with tokens.
Therefore there is an uncertainty of one point in any conclusions drawn from the taking of the tokens.
Moreover, The SST rules for handicap stones give Black the extra points for the extra stones, while orthodox Chinese rules don't. Both players are familiar with orthodox Chinese rules, and may have assumed that the extra white stones played would be counted as handicap stones.
More uninformed comments: the gameI observe that there was a tendency for White to "follow the lead" of Black. There were six sequences of the form card-move-move-card or move-card-card-move, and in five of these it was Black who twice changed the "lead" and White who followed.
If I did not know who the players were, I might guess from this that Black was male, and White was female and was allowing herself to be pushed around. In fact, Rui Naiwei is far too strong a Go player, and far too strong a character, for this conclusion to be appropriate.
