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 nadare joseki. B9 is a trick play, and so is the position above. The refutation for white is hard to find however.

[Diagram]

Tesuji

W1 is natural, but after B2, it seems that white has a problem. The tesuji at W3 saves the day.

[Diagram]

Tesuji continuation

With the moves up to W7, black can cut off W1, but white takes the corner and manages to escape with W7 as well.

If white tries to avoid being sealed in by playing W5 at W7, black will connect under, and white's horrible shape quickly becomes apparent.

[Diagram]

Falling for the trick play.

With W3, white has fallen for the trick play. With the moves up to B8, black seals white into the corner while cutting off W1. White can push through at a, but b is atari, forcing white to capture, after which black can finish his wall with a move at c.

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


[Diagram]

Cut cut cut

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.

[Diagram]

Transposition

If black plays 1 in the previous diagram, this is a transposition of a less common variation of the small nadare joseki (typically black plays 9 at 'c'). The text book continuation for white would be 'a' (if the ladder doesn't work for black) and 'b' (like Bill mentioned).

Text book continuation



Bill: BTW, shouldn't these questions be BQMs?
