Double hane on the 3rd line

Black 3 is a powerful play as it shuts White into the corner. White cannot counter Black 3.

mat But what about White a, Black b, White c? Ahhh I see (first think, then edit...): White captures 3 and Black captures the three white stones!

[Diagram]
The counter fails

Black captures the marked stones and kills the corner as well. As Black 3 in the diagram above is such a powerful play, White has actually made a mistake before and should have extended to Black 1 above herself.

Scartol: Well, I tried to play through the possibilities for the following question, but because of my difficulty reading, I couldn't sort it out.

White lives?

Suppose White plays at 1 here, instead of a. Can Black still kill the corner?

Jan: I think the idea of the original double hane is not to kill White, but to prevent White from escaping. If Black omits 3 in the original diagram, White could later play 4 or a in the following one, for a substantial gain in territory. Your White 1 lets Black make a trumpet connection with very good thickness.
