Hane  

Tim I have a question. I couldn't find any convincing sequence for the reply at to white hane at . Anyone ?

Dieter: but should the corner stone be there? Anyway, ...

Not so good for Black  

After , Black wants to cut at a. But then White plays b and the position crumbles. There is something strange going on here, as White got an extra move, so there is no standard pattern involved.
