Black captures the two white stones and White throws in...
Anonymous: It should also be mentioned that , which would normally secure the second eye, does not work in this case, because of shortage of liberties. captures!
TimH (18k): Huh? Why do you say "would normally secure the second eye"?
Answer to TimH: Lets give Black an extra liberty. must be played at the outside liberty. captures the two white stones. With the throw in is no longer a problem.
Why doesn't this work?
Tas: because that allows black to create a straight four, which is alive.
And then Black plays on the other vital point. This is a miai for life, where black can play at either 3 or 4 if white plays at the other one.
