Variations of Our Solution (IIIb)

Tricking KataGo (Triple-Ko)

VAR (C) (A) (.1) (.3)

: ( 222km)
White peeps at the upper edge.

: (111 222ko)
Black connects at the upper edge, but will still lose the game.

Ignoring White's peep will not help either.
It is also too late now to insert Michal Redmond's kikashi at . White will still cut at , as in the subvariation here.

:
Black has to defend against White's throw-in at .

White ignores Black's atari in the lower left.

Connecting at , instead, would be a severe mistake, bringing Black's large group at the right back to life.

White will win the game by a large margin.
