Cut cut cut ?  

This page discusses the violent cut at B2, which is considered an overplay but definitely not easy to refute.

[Diagram]
Normal continuation  

The normal continuation for black is to play B4. Then with W5 and further, white turns the position into a variation of the nadare joseki.

[Diagram]
Nadare variation  

By playing like this, black can also get into the same position from the small nadare joseki. B9 is a trick play, and so is the position above.

See small avalanche - trick play for the correct response to the trick play.

Bitter 10k blitz fight  

This is how it went in my last game. The game continued with Ba, Wb, c, d, e, f. I ended up in reasonable shape and nothing died (stones W1 and white+square got captured). Feel free to put here a more enlightened example :) --Sigmundur


erislover: I am hardly an expert but this seems the natural move to me. After W7 I do not see how black can get a good result.

Seems natural, but isn't  

W1, W7 in the above diagram, seems like a natural move but isn't. After B2, white is out of options


erislover Thanks for your input. I read a ko from black's play, so white isn't out of options, but your "correct move" sequence is better than that. Thanks!

[Diagram]
Correct move  

After these moves, there is no escape for black. If black tries a, we get the next diagrams

[Diagram]
Correct move, cont'd  

If black plays B1 and then cuts with B3, white stretches and black loses his stones. Black cannot captur white if she answers a with b. Note that after exchanging a for b, the geta at c does not succesfully contain the white group, as white can push trough at d.

[Diagram]
Correct move, cont'd 2  

If after W2 black clamps with B3, white connects. After this sequence (11 at W6), white plays a and captures black

What if black responds to 3 with 4? I tried out a few sequences and black seems to get a good result. Is there a way for white to take advantage of black's joseki deviation?

PetriP? You could read the article by Alexandre Dinerchtein from [ext] http://www.go4go.net/english/article/tricky/ . I think B is quite okay anyways not too bad, if You rememer/understand all the variations.

[Diagram]
sacrifice and seal in  

AndyPierce: I'm no expert but my guess is the usual thought would be for white to add a second stone to white+circle and sacrifice both in order to seal black into the corner and blight the black+circle stone. White has some cutting points to deal with, but should be able to handle it (probably white fixes up at a next). Black's corner is only 10 points (if black eventually takes W9) and black's play has been inconsistent with his black+circle intent to develop on the left side.

[Diagram]
Double attack  

Bill: The descent, W7, attacks both B2 - B4 and black+circle - B6. Black is in trouble.

[Diagram]
Double attack (2)  

Bill: For instance, if B1, W2 defends against the ladder (B2). Now if B3, W4 is solid. Black's disadvantage is clear.

[Diagram]
Double attack (3)  

Bill: Black might try B1, but W2 is an adequate reply. Now through W6 is still good for White.

(unkx80 note: If B3 at a, then we transpose to small avalanche - trick play.)

Mistake at 4  

Dieter: If W4 here, she ends up with two severe cutting points.
