Catching the corner  

Rich: In a game last night, I managed to play white+circle in sente; my opponent thought a group that big (10-12 pts) must be able to live - until I played W1.

Did black have a chance at this point? We played it out and couldn't see anything; is 1 also the vital point for black?

Black dies  

Hans: Black seems to die. The only chance for black is to connect at a instead of B2 and put all his hopes on a seki.

Hans: May be this is a seki. Later I may have more time to examine this.

Rich: Interesting position; I keep coming up with death by rabbit, though...

Dieter: Here Black dies either by being cut or rabbity six. But if B4 at a he lives. I keep reading.
