Can anyone stronger than me (especially the two people who correctly predicted :w16:

) explain why White didn't tenuki for :w16:

? Is this point just too big (takes territory for White, denies territory for Black, makes a base, leaves Black with an open skirt and without a solid base) to pass up? Hmm, when I list all those reasons I start to see the point

We've seen a few suggestions that Black will play at C12 (and many people wanted to play there even before now!). Any other ideas?

See the difference? Also, if white doesn't play :w2:

in the bottom diagram, black's invasion on the side will be severe.

Posted: **Tue Aug 24, 2010 2:40 pm**

The more interesting question for me is why W didn't play Topazg's move--it would put less pressure on B, but give white sente.

Posted: **Tue Aug 24, 2010 2:58 pm**

I guess the question for me is, does it actually give white sente? Can black reasonably play like this or not? (Edit: probably not, huh?)

Anyway, my prediction for the next move is :b3:

above.

Posted: **Tue Aug 24, 2010 4:05 pm**

C12, maybe. I would play this, threatening to invade, then play a move on the top.

yes, besides what you already said there is a tesuji black can play later

below the weakness that black can exploit later in the game if white played tenuki ( :w16:

).
This also means that instead of this playing :b21:

directly is also a great invasion point.
The reason I wrote "later in the game" is because if black plays it now, the bottom gets weak.

The way white played it in the real game means he has a very solid corner,
good endgame, attack option on the bottom group and the left side is hard to
invade partly because of this strong corner. This might be the reason the other
two suggestions E3 &C4 are not what was actually played.

my thoughts for the next move:

I think the blacks group at the bottom is safe for now. (that was the goal of the attaching move) so black can take sente.

I see a, b and c as possible continuations.

c: This thickness in the corner white just build might make c less valuable as well. It still looks like a good point, but I'm not sure. It might be that white ignores is. White can then build quite a big right side. Therefore maybe something on the right side is not a bad idea either for black. Not easy to decide what though. Black does not want to create another group too close to the group on the bottom (this would allow white to do a splitting attack.)

b: This looks like a very solid move, but maybe a little slow. It does threaten a huge top though. but also result in a rather boring game.

a: I would like to play a. forcing white to play towards the black thickness (corner).
This would allow black to get a solid group on the right side without damaging the bottom group.

looking ahead:

This also creates potential targets for later. (Splitting the bottom two stones once black gets stronger, or attack the top right white group.)

The idea is that it makes black safer while over-concentrating white. When black plays C12, white still has to respond around C8 or D8. ( It may have flaws, but that is the idea. )
We all know that black wants to tenuki - probably to the right side - and this attempts to make his group safe before doing so.
