Kirby must reply with B1, of course.

Magicwand can go this far with W2, as the connection is still strong enough to handle the nose tesuji.

I like this alright. I am safe with my group, and can have some points in this area.

One joseki goes something like this:

White continues with some thing like "a" or "b". Black usually plays 3 instead of blocking because of the aji left in the c area.

Maybe I'll play this way. I haven't quite decided, yet. I'll decide after Magicwand plays :w2:

(if he does).

This is interesting. Could you give an example of how white can exploit the aji if black blocks? Thanks!

If black blocks, white can't quite do anything straight away, but it is very easy for him to play moves in sente around the area. If black ignores white 2, for example, white can try to gouge out the corner.

Obviously black can try to resist (maybe 5 one space higher is annoying), but white clearly has some good points to aim at in black's 'territory'.

The descent also gives white a forcing move at x, which might turn out to be vital for eyeshape, so not descending could be viewed as a harsher attack. I don't know how important this factor is.

White usually plays the clamp now because if black plays to protect his corner during the fight, he will be able to block later, and white will have lost the chance to make this aji.

Descending isn't actually bad, and can be seen in professional games, but isn't particularly common.

EDIT: Actually, my suggested annoying move is not to be feared. White can just live in the corner if necessary:

I think it's best to put pressure on his group this way. I can get territory by attacking his group.

White could give me a counter pincer, for example, but his group is weak enough that I don't think he'd be successful with it. He has weaknesses around "a", and I can continue to jump out:

If he does pincer, I can attack his pincer stone as well. I don't think that white can successfully counter my attack.

The game is still going pretty smoothly.

If I step back and ignore the score, I can try to consider what stones I've played that seem inefficient:

The two marked stones, above, seem to be the most efficient of the ones I've played. However, of the two, the non-tengen stone at least seemed to give me benefit with invading the top. Furthermore, white has still left the area open, so I have potential to save the stone in the future (maybe).

In either case, those two stones seem inefficient to me. My other stones seem alright, I think, so I feel OK about the game.

Anyway, I predict white might pincer my stone, but I think I will be at an advantage if he does.

Black is still ahead, but White is on pace to win, thanks to Black's lackluster play. I am glad that Kirby is thinking of attacking. However, White has only one weak group now.

is the obvious play to try to mount an attack, leaning against the White group on the bottom side. But then Black does not seem to have much against the marked White stone, given the weakness of the Black tengen stone (marked).

here looks more flexible, aiming at the one space jump or the jump attachment (marked).

It seems to me that the key to this position is Black's tengen stone. If it dies a dog's death it will be hard for Black to win. :b1:

comes to mind. Now B"a" does attack the marked White stone as well as the White group on the bottom side. If White plays on the bottom side, then B"b" looks good.

Edit: While I was writing this note, Kirby played the approach on the bottom side.

This is a good play, too. It extends Black's framework while attacking, a dual-purpose play.

Edit: Unhidden.

Another overplay by Magicwand, I think.

The most obvious danger is that black might play the reflexive tobi, then white starts making a serious moyo:

Now white will be able to save one side or the other.

If W2 above works well for white, then maybe black can use it.

I think that this is Kirby's best for his next move.

Definitely overplay, but I would be interested in other players' opinions on how to best exploit this situation.

My idea would be to lean here, in order to cap the left group afterwards.
