67.65.164.238: Alternate responses for white when pincered (2008-05-20 14:20) [#4691]
[Diagram]
corner  

A colleague of mines often plays the circle spot. Why I cannot find any responses in the go websites? Is this a bad move? if so, how can i punish it?

White's slide looks low and slow.

[Diagram]
Jump attachment  

The jump attachment at B1 looks attractive. W2 - W8 is White's most stubborn response. (Otherwise White is easily contained.)

[Diagram]
Thickness  

Rather than capture white+circle, B1 is a key play, sacrificing the black+circle stones for great thickness.

corner  

I would probably play like this, with B7 either at simply at a, or at b to seal white in completely. Black gets thickness in exchange for about 10 points for white.

corner  

W2 like this is unreasonable. white+circle becomes mochikomi and white ends in gote with a semi-weak group, while black gets a large corner.

Sacrifice  

W1 allows White to sacrifice the corner. All of White's plays are kikashi. Perhaps B4 should be at 6 right away.

Yes, I had considered this, but it seems goo for black too, connectng with the pincer stone. I think B4 should be at B6, otherwise W5 can be at B8 and allow white to connect.

Bill: Re: Alternate responses for white when pincered (2008-05-21 18:28) [#4698]

Black gets to connect, but as White I would be happy to give up two stones in return for four forced replies. :)

As for the crosscut and connection, the connection did not look all that great to me.

Connection, but shape is not good  

Instead of W3, maybe White should extend to 4.

Exchange  

This is not so bad for White, but I think that sacrificing the corner is better. :)

71.192.11.206: Even with a more distant pincer ... (2008-05-21 19:17) [#4699]

Bob McGuigan: In his book Tricks in Joseki Yilun Yang analyses the slide when Black has made a two space low pincer:

Still incorrect  


Mr. Yang gives the following two diagrams:

[Diagram]
Sequence 1  

After B9 White must defend at a so the white+square stone becomes useless.

[Diagram]
Sequence 2  

White is split into two weak groups, but of course this is a different pincer than in the original question.

A kyu once played this against me in a game. It's not mentioned anywhere on SL, but how is it a bad move? It doesn't seem punishable.

Herman: W4 is slow and heavy. B5 is enough punishment. Normally, with the one point jump, white could play a, but that is not possible now.
