Variations of Our Solution (IIIa)

No Early Kikashi

VAR (.1) (.3)

: ( 648ab)
White blocks at the top, preventing Black's sente move at the same point.

:
Black plays his kikashi in the hanezeki "early".

:
Black can still create an eye in the left centre, so temporarily ignoring Black's kikashi in the hanezeki and forcing at is pointless.

:
White takes the last valuable point on the board.

:
The Main Semeai continues.

Black plays 2/3 reductions.

Please assume the rejection of Dany's Sacrifice and Black's second kikashi in the hanezeki (, ) played before.
