Dieter: What if White 4 plays hane at a?

Kungfu Aim at the cut at 7 while attacking the marked white stone. I am not sure of an exact sequence, but I believe I could get a similar result. Of course, it would have changed the entire game. If I managed to capture the marked stone and White connects at 7, I might move p8 and her recently connected stones look bad to me. Either way I feel White is weak in that area.

Unfortunately, White could also connect right away, so extending might not be best. If I cross-cut, the variations start to get numerous. But I would remember that this is white's territory to begin with, so when crosscutting, I would try to descend on the right and extend towards k9.

5 at a or b? Maybe b.

No matter what White does, I feel I can make a weak white group somewhere, or at the very least give him what was already his and pressure from the outside. White 4 looks like it's weakening my moyo, so I'd have to take into consideration if it's worth letting her live inside my moyo.. If I can secure enough territory around my moyo as she takes when she invades, perhaps living small on the right is worth it (considering it used to be White's).

Dieter: Certainly not 5.

Alternative. The invasion at a remains open. Black's moyo is seriously damaged.

Dieter: Two ways to look at it. My way is that a tsuke should be answered, very often with a hane, especially for such an important stone as this one. But looking at it "magnetically" helps too. Black 3 tries to break the connection: a hane would simply try to restore it. I really think Black 3 was a bad move, helping the opponent to settle quickly and that it should be at 4 in diagram 1. But White failed to apply some very fundamental principles and therefore didn't punish the bad move at 3.
