is a very hard move. It could be concidered a mistake for black. It is unnecessary complex maybe, a stone at would have been good enough for black.

is the only correct answer to . Next black has no good move at the left side. He would love to play at immediatly. But this is not possible. forces after that becomes possible !

After the cut of a capturing race seems to start. is necessary for black to get 1 more liberty. Thanks to this tesuji black wins the capturing race.

Allthough black made a lot of territory, white made a lot of influence. So the result is possibly even.
