Life In 19x19

in a 3 stone handi against a 1k my opponent (white) tends to favor this opening.

Gotta get gbreakfst. If time allows, I'l return to say why I think it is best.

I think you should try to move out with your stones. It's good to make your own plan, though.

I'd probably consider this, first:

Then, maybe this (though it might strengthen his stone):

I also might consider kicking first:

The kick may not be good, I guess.

Anyway, these are the moves I'd be thinking of.

I briefly thought of pincering the stone, but it's risky because you start to get enclosed:

You could also not play the one-space pincer, which would make things easy.. or 6 could be low.

my resoning was: since both the two sone groups are weak, i attach and make both stronger.
though i ended up losing, this seems like correct thinking to me.

Posted: **Wed May 11, 2011 11:43 am**

There is no need to make either stronger. Just push out between the two, thereby threatening both.

When you attach, you commit yourself. When you push between without attaching, you have greater flexibility to attack either one. He defends one, then you crush the other. Play so that he has to commit first.

@OP: However, if you had another stone nearby, such as the marked stone like this:

...then the tight pincer seems reasonable.
But the problem with the unsupported one-space pincer is that he runs out with 5, and now he is threatening 7 at 'a' or 'b' or 'c':

Your opponent made a mistake with 7, creating a second local group before the first was safe. He should have done something more like this:

...and now the force of your pincer has been blunted.

IMHO, 6 has to be high to be consistent with 4. As mentioned above, 4 is probably an overplay, but 6 low just gives up on the attack.

I have to respectfully disagree with Joaz. The one-space pincer is fine IMO. Continuing from where his last diagram left off,

I see no reason why it's bad to play like this. You also have other choices instead of the marked black stone as well.

I also believe you have a choice whether to play :b6:

high or low. If you're interested, see lessons 135-137 [sl=BadukMadeFunAndEasy]here[/sl], for a bunch of the variations that can ensue.

In my four-stones-handicap-games I always play the one-space-low-pincer, if White takes the corner, I get Sente and make a San-Ren-Sei-Formation. If White jumps up, I play like this

White still has to catch those three stones (Sente for Black), 'a' has a lot of Aji and I have a huge corner. I like : )

yup... feels allright for me. and jumping out is usually bad for W. he should get san-san or double-pincer.

White still has to catch those three stones (Sente for Black), 'a' has a lot of Aji and I have a huge corner. I like : )

This is not good for Black.

Yeah, my opponent kept saying, it's good enough for White and I kept playing it. Still, now he always takes the corner or plays funny variations ^^

my resoning was: since both the two sone groups are weak, i attach and make both stronger.
though i ended up losing, this seems like correct thinking to me.

Not to me.

The kosumi, :b1:

, strengthens the :bc:

stones without strengthening the :wc:

stones. Isn't that a better idea?

In your variation, the :wc:

stone is weakened, but the :bs:

stone is sacrificed and the :bc:

stone is weakened.

No problem with the one-space pincer :b2:

, and

kosumi is a very natural move...

If W cannot close B with one move (say :ws:

above), then B can consider a pincer in the :b4:

direction,
(could also be at (a) or (b), etc.) which also works well with the existing :bs:
