:
This is the position in the main line of Joachim's Ko-Semeai at the moment, when we decided to start the ko-fight in the upper right "early" ( 334).

!!! We will calculate the maximum number of ko-threats in the nakade under the assumption that White must answer any Black move in the nakade in order to save her -stones, because she is unable to capture the hanezeki's tail , instead. !!!

:
Black starts the Nakade Sequence on the lower part of the nakade, as usual.

:
Black has got nine ko-threats in the nakade.
