Solved?

sjoelund (29-30k): Since the standard response for black at a is to invade at , don't we do the same here? If black plays , we answer .

Not solved.

unkx80: Nice attempt there, but this is not solved. and allows Black to connect outside.

Black cannot escape

sjoelund: Hopefully this is the right sollution. It seems to work as it should. "a" and "b" are miai for black, but none work. ichundso?: Black shoudl ignore (as seen below)

Black tries "a"

This BulkyFive dies quickly

Black tries "b"

This is also the shape of a BulkyFive

Failure (1)

If we block at , forces . Black then plays and has a living formation.

Brent: Actually, White can still make a ko: see rectangular six in the corner. But of course playing at is still the way to go.

unkx80: at a lives unconditionally.

ichundso?: a "a" too.

Failure (2)

If we don't defend the cut in the other failure, black escapes.

ichundso? This is the best result for white i can think about. at wont be good, because black wont play at since he can get 2 eyes (no need to escape anymore as seen below). Note that avoids a ko fight because if he cant push at a if

bla

white cant push at a

unkx80: ichundso?, your reasoning is not quite right. Please see the /Solution page.
