White 1 is essential to prevent Black from creating a bulky five inside White's eye space.
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...
ProtoDeuteric: With this sequence (which I believe is not katteyomi), white is alive and well.
LukeNine45: What about at
?
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
.
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.
Making the bulky five immediately works too but requires a tesuji at 4.
It would be a grave mistake to play 6 not at a. White captures at 7 ...
White has a and b to assure life.
