Gokyo Shumyo, Section 1, Problem 63 / Solution

Main line  

White 1 is essential to prevent Black from creating a bulky five inside White's eye space.


If black plays B2, white needs to be careful...

White falls into the trap  

Black plays B6 at B2, and white is dead. (W7 at W5, B8 at W1 maks the bulky five shape.)

The correct response  

White lives this way.

Another Solution?  

ProtoDeuteric: I can't see why W1 in this diagram would not work. I think that the above statement that B2 can now make white's eye a bulky five is short sighted...

Continuation, W1 at "a"  

ProtoDeuteric: With this sequence (which I believe is not katteyomi), white is alive and well.

LukeNine45: What about B4 at W5?

If B4 at W5 (B2 at "a")  

ProtoDeuteric: If B4 of the previous diagram was instead played where W5 was, then...well...looks like...no...wait...no...I guess you are right. In this variation of what has turned out to be a failed attempt, I misread where black would have played after W5.


If White thinks to solve her problems by connecting, Black forces with 2, next creates the bulky five. Black 6 is also important. Let's go into 2 and 6.

Var at 2 in failure diagram  

Making the bulky five immediately works too but requires a tesuji at 4.

Mistake at 6 in failure diagram  

It would be a grave mistake to play 6 not at a. White captures at 7 ...

Mistake at 6 in failure diagram  

White has ''a'' and ''b'' to assure life.
