Black to play

Kills  

AndyPierce: There is death in the hane for black, making miai of the circle points for a kill.

Also Kills?  

RiffRaff: I think this would also work.

Skylancer: Is B3 really necessary? White is still dead because W2 is death in gote.

[Diagram]
Still dead.  

B3 tenuki leaves a and b as miai for the kill.

For that matter, I think that any other W2 is also death in gote : B1 seems to kill without leaving any ko threats.
erislover If black plays tenuki because of miai for the kill, then a and b do threaten to live so white will get a ko threat.

Alex: Right, but the point is that W2 is not, itself a ko threat, nor is any other W2. After B1, White needs three moves to live, so B1 leaves no ko threats. White is not going to play W2 and die in gote just to create one ko threat for later. ;-)

[Diagram]
Kills from the outside  

erislover - Almost anything seems to kill. White has no response here, either. a is met by b, b is met by c, ...

zinger: I like this way best - killing from the outside. Later, if this group comes back to life due to a ko elsewhere, B1 will still be a good move.

Tas: But if the killing move leaves no ko threats there are no way a ko elsewhere wil make it come back to life...

[Diagram]
Other options  

Xanthus: Just to be complete, these two B1's also seem to kill. This gives a nice total of five possibilities!

zinger: And beyond that, there is the absurd-looking move at a, which technically also kills, but is obviously worse.


White to play

[Diagram]
Life for White  

RiffRaff: With white to play, life looks pretty easy. So overall status would be unsettled.

Tas: Shouldnt this be moved to the solution page?
