BSR 2003 B5 Alternative

Black Sheep Rengo 2003 Alternative to Black 5  

How about this one? It seems to me that the obvious white answer would already be a mistake:

White's mistake  

And White is forced into terrible shape. Instead play 3 at 6 might reduce the damage, but then Black's shape still looks a little better. (Expect a double hane next.)

So probably White has to treat her stones lightly.

Bill: I think you have shown us an obvious wrong answer. ;-)

dnerra: Yes! :-) I think I mostly wanted to point out that starting with a fight at tengen doesn't mean you can easily avoid terrible "joseki" mistakes, i.e. bad mistakes in the first few moves. I think by the usual standard of "non-joseki", the diagram above is pretty much a disaster.

I don't know if there is an obvious right answer, but

White answer?  

comes to mind.

dnerra: Then Black a or b next?
