Strange things happen at the 1-2 point!
Thanatos13: Belly hit sounds right. see belly attachment tesuji
Isn't this seki? If Black tries to play at either a or b the resulting capture leaves a living BentFourInTheCorner, since in each case there are miai to cut the space into two parts.
unkx80: This is not seki, this is a dead group. Please refer to rectangular six in the corner. Also, what you called the bent four in the corner should be simply termed as bent four.
KarlKnechtel: (after referring as requested) Ah. I neglected that Black's play at a would capture the group with the outside liberties filled :) Forest and trees are miai in my vision it seems ;)
Also, could someone refute this White 1 below (which was my instinctive, 5-seconds-of-thought answer):
unkx80: Of course White 1 is wrong. Otherwise this diagram is perfect.
KarlKnechtel: I can get *something* right at least then ;)
And just to follow up, White 3 at 4 leaves a dead shape in the large corner eye, and Black plays 4 at a to prevent a second eye. Right?
unkx80: Yes.
