3-4 point high approach, keima, attachment, cut
This page discusses the violent cut at , which is considered an overplay but definitely not easy to refute.
The normal continuation for black is to play . Then with
and further, white turns the position into a variation of the nadare joseki.
By playing like this, black can also get into the same position from the small nadare joseki. is a trick play, and so is the position above.
See small avalanche - trick play for the correct response to the trick play.
Discussion
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 and
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 I do not see how black can get a good result.
,
in the above diagram, seems like a natural move but isn't. After
, 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!
If black plays and then cuts with
, 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.
If after black clamps with
, white connects. After this sequence (11 at
), 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
http://www.go4go.net/english/article/tricky/ . I think B is quite okay anyways not too bad, if You rememer/understand all the variations.
AndyPierce: I'm no expert but my guess is the usual thought would be for white to add a second stone to and sacrifice both in order to seal black into the corner and blight the
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
) and black's play has been inconsistent with his
intent to develop on the left side.
Bill: For instance, if ,
defends against the ladder (
). Now if
,
is solid. Black's disadvantage is clear.
Bill: Black might try , but
is an adequate reply. Now through
is still good for White.
(unkx80 note: If at a, then we transpose to small avalanche - trick play.)
