Gokyo Shumyo, Section 1, Problem 63 / Solution

[Diagram]
Main line  

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

[Diagram]
Continuation  
[Diagram]
Continuation  
[Diagram]
Variation  

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

[Diagram]
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.)

[Diagram]
The correct response  

White lives this way.


[Diagram]
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...

[Diagram]
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?

[Diagram]
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.


[Diagram]
Failure  

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.

[Diagram]
Var at 2 in failure diagram  

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

[Diagram]
Mistake at 6 in failure diagram  

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

[Diagram]
Mistake at 6 in failure diagram  

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