I think M5, as someone suggested earlier (Magicwand, maybe?) might be good.

I would prefer to be able to solidify that area with the nice ikken tobi at k5 but right now I dont think B can block at a.

W just has too many liberties and b is too many cutting points.

So maybe w will want to induce a sequence to enable a clean capture with k5 for example:

EDIT:
I just was thinking about the position and it doesnt look good enough for b.
I think B should play on a larger scale and try to cover the peep at a in order to preserve the aji of the marked stones.

EDIT2:
OK maybe im making too many guesses but i keep looking back at the thread and theres no new posts so... and i hid the diagrams cause it got too long.

I think my move order was inferior and that p5 immediately is a firm move.
If w peeps at a before playing move 32 in diagram 2 , it makes the b move 29 at q9 pointless.

I think White will play 1 next. Hopefully he will, because then I can stop saying how big this move is every single time I post. The point 'a' starts glowing every time I look at the board, but I think it would be early to play this now, Black is undercut here so it doesn't matter too much if Black spends an extra move on the bottom. Also, I'm not sure that there is a clean way for Black to fix all the aji on the bottom in one move anyway.

By the way, thanks for doing this dfan! Are there many comments that you are skipping because they affect the discussion or are we getting most of them?

You are quite welcome! I am posting most of the comments, but I try to avoid ones that might spoil the future of the game a little (e.g., I wouldn't have posted a comment that said how your :w1:

would have been a good alternative earlier).

This has been very interesting to me so far. For example, Joaz guessed Black's basic strategy in the lower right back when Black played R5, but the execution of it has had a bunch of subtleties that people didn't predict. Of course, I don't know whether the actual moves have been been objectively better than the ones people here have suggested or if it is just a matter of style.

By the way, one of the actual game comments said that White's last move at Q7 could have been at R7, but it did not mention R6.

I like c13, too, but maybe g17.

This looks like a great middle-game "find the next move" problem. I would be very interested if the game commentary says anything about the various possibilities here. My top four choices are listed:

a) and b) are both very large points but not really vital
c) is a vital point with a lot of aji, but feels like an overplay now
d) is a point both sides would like for expansion, related to the aji at c

I will pick "d".

Posted: **Tue Aug 31, 2010 6:51 pm**

I like the 'd' option at f6 also.

Seems like a good idea to try to make b spend as many moves as possible on the bottom.

I think it makes b overconcentrated alot. there is still q2 yose that is threatening to o2 connecting m3 stones and monkey jump on bottom.

I agree! I think I'm going to leave this position up for a bit longer and collect a few more opinions.

Posted: **Wed Sep 01, 2010 1:27 am**

Maybe W wants to try this probe at 30 first before playing at f6.
If the position ends up like this W can have this ko sequence starting with 'a' later on.

Isn't this good for black? (I'm not sure if 31 is correct, but even assuming it is). I don't care if the bottom left stones come under attack, they're pretty worthless and I don't think White has a follow-up to capture them cleanly.

'd' is a good point but...my feeling say it is wrong.
so i cameup with this probe which will create aji.
depended on how he answer after this you can tenuki with aji or try to live.

...
a) and b) are both very large points but not really vital
c) is a vital point with a lot of aji, but feels like an overplay now
d) is a point both sides would like for expansion, related to the aji at c

I will pick "d".

As Mitsun says, both 'a' and 'b' are big, but neither is urgent. There is no strong follow up move for 'a', so it lacks urgency, and there are miai following moves for 'b', but still there are no life and death issues.

I think 'd is the wrong direction for the following reason. White has a wall over on the lower left side that looks efficient. Black has three stones nearby that look misplaced. If white allows black to fix his directional aji, then white loses his advantage.

White's influence looks like this:

Black's direction is less focussed, and looks like this:

If white plays as below, both black and white get more or less the direction that they want, both get an increase in territory ( white's is larger but more open ), but the weakness at 'c' disappears. This is a net profit for black.

The only way for white to properly use the wall is with 'c'. It is dead center in the area of influence that the wall has. It keeps black off balance, not allowing him to make his lower stones cooperate.

Is it premature? Possibly. But if white does not do it now, black can play this:

Now black's weakness is gone, and black is threatening to get ahead in territory.

So my prediction is this:
