Highly speculative solution by lavalyn:
nullifies the threat of the false eye by creating a tiger shape defending the eye's vital point.
KarlKnechtel: I'm convinced this is it. I saw as playing at what looked like a key point of the space surrounded by Black, and also making good shape - but the shape I saw was the nameless one made by
and the
stones. :)
Deebster: Charles Matthews has dubbed it the table shape.
unkx80: Sometimes good feeling is important in life and death situations. Often good feeling can help one in making the correct choices, such as in this diagram. But this feeling needs to be cultivated.
Of course, if there were a stone (black or white) at a, this defence wouldn't work because of shortage of liberties.
unkx80: is another possible play by Black. But when
makes a throw-in, White can connect at
as there is an extra liberty at a.
byorgey: If Black plays , then White ataris with
, leading to the same configuration seen in the diagrams above.
Just trying to create eye space doesn't work - Black makes an eye false.
Moosky: I think Black answering directly at (instead of
) is even better. If
at
, then
at the circle.
lavalyn While doing some revision and a bad edit:
Don't get too clever thinking White has caught Black in snapback - White needs one more liberty for that!!!
