Variations of the Professional Solution

VARP (.1)

: ( 0730ca)
Black starts the mutual occupation of opponent's liberties in the Main Semeai.

: ( 0730cab)
White is forced to insert "her" kikashi in the bamboo joint before capturing the hanezeki's tail, reaching a drawn game.

Otherwise, e.g. if White continues with a move at (and does not get back to the kikashi in due time later), she will lose by three points in the Capture Variation.

:
As usual, this atari provides White with a slight territorial advantage, compared to the solid connection at .

:
Black continues with occupying opponent's liberties in the Main Semeai.
Black will use his won liberty to connect at later. He will also be able to destroy White's potential point of territory a in the centre.

Black second option is to defend his lower left corner, with a move at (letting White capture both hasami-tsuke stones), also reaching a drawn game.

In principle, these options will follow the course of moves of either 0730ca or 0730cb. However, White is one point worse here, due to her kikashi in the bamboo joint.

The game will end in a draw (jigo).
