White plays KataGo's crosscut.

:
Black gives atari from the inside.

: ( A 222bd)
White continues with the endgame in the lower left corner.

However, as we know now, White must erase her weakness in the guzumi area with a move at before, in order to not lose one point overall unnecessarily.

:
White connects at the lower edge, but this connection is gote.

This is the latest moment that White could play her defensive move in the guzumi area. It will result a change in the order of moves with the subvariation above.
Please note that Black would be unable to capture White just played stones with , as this move would push him below the Punishment Semeai Liberty Level.

: (117 222bf ;

 116 222bj)
Black defends his upper left corner.
By this move, Black is par with the Main Semeai Liberty Level again.

Black might also consider capturing White's two stones in the lower left with , instead. This move would not affect the final scores of the game.
However, Black has one surplus Main Semeai Liberty to spend, so he must utilise White's weakness in the guzumi area by pushing with there.

: (117 222bk ; A 222bm)
White sacrifices her two stones in the lower left and defends in the guzumi area, also continuing with the Main Semeai.

White must not lose any tempo in the Main Semeai here. Neither must she connect her two stones in the lower left with , nor her single stone at the upper edge with .

:
Now, Black captures White's two stones in the lower left, also occupying a liberty of White's left-hand group.

:
White also continues with the Main Semeai.

: ( 129 222bp)
White continues with the Main Semeai.

However, if she played the newly found wedge in the left centre, instead, she would gain one point overall.

:
Black continues at the left, as "usual".

It might be tempting to push at , instead, but White will answer by occupying another liberty of Black's group at the right, e.g. with , instead of blocking locally. Black will have been pushed below the Punishment Semeai Liberty Level, and so will lose the Punishment Semeai, and the game by a large margin.

Black must not play any reduction.

After her decision point, White will connect at at the upper edge. Black will play his kikashi of , thereafter.
