Attempt

Black Throw-in

Hikaru79: I think that the Black throw-in at B1 kills the group, although not unconditionally. White has a couple of choices.

White connects

If white decides to connect, it's immediate game over.

White connects

If white resists with W1, it becomes a ko for life as far as I can see...



Bill: After the first diagram, White can play W1. At this point either player can make seki or throw in to make a ko (which the opponent takes first).

Unfavorable ko

W5 takes ko.

Bill: If B2 takes the ko, White has W3 as a local ko threat. This is bad for Black.
