The points a and b are miai for life. Related proverb: Strange Things Happen At The One Two Point - in this case you need to know which of the two 1-2 points, of course.
Black has two sure eyes at a and b.
If White next blocks at a, Black makes a big eye at b. And if White draws out at b, Black enlarges the eye with a. Caution: if White has a stone on one of the encircled points, her move at b suddenly works and Black is dead, although a lot of aji remains, because he can break out into the centre (in this position).
Grauniad: After b and a above, White can play 3 to 9 or some similar sequence. In this case, I don't see how Black can make a second eye. Jasonred : Grauniad, after some reflection, I think my move 6 in the FOLLOWING diagram is not even necessary... Just keep enlargening the eyespace! Black 6 in your sequence SEEMS wrong to me, I think black 6 at 7 in your diagram? So... like this?:
Though I think that white should really play 2 at 3...
Jasonred : I think that this is how it goes? I'm no sure though. I DO know that 7 seems to be a good idea, or blacks going to escape AND destroy white's shape, and cause general chaos. I played 8 hoping to threaten the circled stone, hoping that white must reply at x or y... I guess if White plays 9 at this point, I would either play at a or b... probably a... in this battle, if you keep stretching to the right, so will black, right?
Grauniad: Jasonred, extending your diagram above reveals the solution in which Black escapes to the centre. All this must have been obvious to stronger players than us. Some Deshi now needs to WikiMasterEdit this discussion (possibly by removing it). Jasonred : Sadly my friend, it WAS obvious to a weak player like me... evidently, I can't explain my diagrams properly or something.. anyhow, there's a LOT of things black can do after extending that far to the right, which is why white more or less HAS to hane early on, letting black solidify that eye...
Black 1 is wrong. After 2, Black 3 and 5 seem to make the most of it, but when White cuts at 6 it's all over.
If Black plays at the other 1-2 point, it is also wrong. 5 and 6 are miai for the kill. After white 6, Black can play neither a nor b because of damezumari.
Black 1 here is also wrong. White can even respond at ease to the hanes at 3 and 5, because whatever Black does, The points a and b remain miai for the kill.
Finally, what about making the corner eyespace as big as possible, with 1 here? White plays hane at 2, threatening to capture three stones. Black has to make a solid connection. This is as in KanazawaProblemOne, but with a white stone at 2, and Black is dead.
White at a kills the black group with two more white stones.
unkx80: It might be better to have White 2 block on the outside.
