This looks like a great middle-game "find the next move" problem.

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

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.

OK, so this is the last time I'll mention my preference for C12/C13 I promise.

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:

I think B will play f6 next and that W will respond.
I don't think B can nullify the marked stones with move 33.

In the first diagram, B plays the kosumi for move 33.
W can play this sequence and get a ko with a-f
B gets to play p2 also but it looks too risky.

In the second diagram, B plays nobi for 33.
W can run into the center using the tsukekoshi at move 36.
B should be able to make some profit by attacking these stones.

If black does play 31 and white answers with 32, then 33 below looks better for black.

Indeed, I can't help but wonder if white would bother with such a passive play for :w32:

That is interesting.
I would respond to B 31 if at all possible instead of rushing to play a move like this W 32.
Any damage w can do by playing 32 now is minus the damage w could have done after responding at d7.

B33 is another interesting but risky move. It looks more complicated than the 2 options i suggested.

We should think about the variations that arise after this move.

So far I prefer B 33 at k4

Hidden to save space:

After either of the marked W nobis the B moves that i think of are at 'a' to 'd'.

I'm not sure, but lets say that w plays at m5 first.

With B 'a' W can cut out into the center with the kosumi at 38.
B can't do his prior moves justice by giving up the marked stones.

So lets look at option 'b'...
B does not have the option of semeai because of the warikomi with W42 safely taking a large profit.

It is interesting that no one seemed to look at anything but x for Black. The commentary for this move is all about choosing between :b31:

, a, and b. (I don't want to say what their conclusions were yet, though.)

Kirby and Joaz (and others): What do you will think will happen down here? Which stones will live, which will die, which will run?

Chew Terr · **#174**

I am betting that M4 stays dead, but H4 and E3 both run.

plankton · **#175**

I liked the double extension sequence with W 38 connecting via atekomi at 'a' or underneath. There is ugly kikashi left at 'b' so B probably needs to spend a move to defend that also.

I thought that W also had the option of living with W 42 connecting underneath.

But B can attempt to kill W with the hae at 45 then connecting at 'a'

So I have come to agree with Kirby's suggestion to play out the left sequence first.

Joaz Banbeck · **#177**

EDIT: I wrote most of this last night and then posted it this morning without noticing that Dfan had posted...

Black has 16 stones on the board. One is a sacrifice, four are on the opposite side of the board. Of the remaining 11, 8 are dependant on the death of M3/M4to stay alive. That is half of black's stones. Thus killing M3/M4 and keeping them dead is black's top priority.

Black's second priority is killing H3/H4. If he can do this, he is probably ahead, with better prospects. ( Black would have 30 points in the lower side, and 10 each in the upper corners for a total of 50, and he can extend into the center. White would have about 20 points on the right side and 15 to 20 on the left for a total of maybe 40. White can extend northward along either side, but has to face a black shimari looking down at him. )

White, of course, realizes all of this, and has bet the farm on the survival of H3/H4. If it can move out into the center and kill F4, white is way ahead.

If F4 survives, it looks like this:

If both run, as marked with squares, white looks beter. The circled white stones are more of a threat to black's running group than the circled black stones are to white's running group.

So as long as H3/H4 survives, white looks like he is ahead either way.

In summary, if H3/H4 dies, black is ahead. If it lives, white is ahead.
If white gets H5, it probably lives. Therefore, black has to try to kill it with H5. That is my prediction for move 33.

Kirby · **#178**

Didn't dfan already play 33?

Kirby · **#179**

I guess L2... Though, black seems overconcentrated

Second guess is just G5 because of that.

Joaz Banbeck · **#180**

As stated in my previous post, black's top priority is killing M3/M4. K2 theatens to help them live. Therefore, black's next is a no-brainer:

At that point, white's group cannot live on the side by itself. It either has to connect underneath to C2 or cut its way out with G5:

Connecting resolves all the tension and leaves black with sente:

...therefore, white wants to cut first, then threaten to connect:

Now if black had taken my advice earlier and exchanged E6 for D6, then laddering 38 would be trivial:

But, the best black can do is play the ladder-breaker late like this:
