# 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.

Continuation
Continuation
Variation

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

White falls into the trap

Black plays at , and white is dead. ( at , at maks the bulky five shape.)

The correct response

White lives this way.

Another Solution?

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

Continuation, at "a"

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

If at ( at "a")

ProtoDeuteric: If of the previous diagram was instead played where 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 .

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.

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.
