Premature Ending?

This is where the game between Takemiya Masaki (Black) and Lee Changho (White) played on 1999-05-28 in Tianjin ended with White winning by 7.5

Question... with the possible exception of the black+square stone? Does this force a move inside?



I think that the game was ended prematurely. If Black had played at black+square, White would have to play in his own territory, reducing his score by one point. If he doesn't...

Black lives in seki?

This results. Black has taken some of White's territory. This is enough to turn the tide of the game to a black win.

Niklaus: Black lives in seki? I guess you missed that the black+square are dead...



Hikaru79 Thanks for pointing that out.

Charles Let's leave this: it has value to some as an example of a very temporary seki, that one would have to visualise a few plays ahead.

Tderz: Is this something for rule freaks? It seems I don't get it. In a game (resp. after = during counting) I'd simply remove the black+square from the board. Is someone suggesting you'd need to make a black move a to remove the stones from the board?

Temporary Seki seems to me a misleading name for approach liberty creating problems in, e.g. the style of shortage of liberties. Perhaps it was meant here as time-tesuji.

Bill: You and I may prefer to call it a false seki.
