Indeed, 13 at k16 is fine, and indeed the most common pro move in this position, closely followed by k17 and then l17. Sure it leaves an invasion at m17 for later, but at this stage of the opening the left side is bigger (c14 approach after k16 is natural flow). k16 makes a good relationship with d16 and treats o17 lightly. Sure l17 hangs on to o17 more, but it's also a tad heavier as a black invasion at j17 could even be an attacking invasion on the cramped 2 space in the future. I had this shape in a recent game of mine: http://www.online-go.com/games/board.php?boardID=319135.

After seeing this move, I basically have been thinking about two different options. I'll go over the one I decided against first.

This move is something I really would like to play, but unfortunately seems like it is probably unreasonable. Ultimately, there are a lot of flaws if I play this way I think. The bottom is too open at this point and I have said before I think the bottom and left sides are where I'd like to try to develop and playing this way counters that argument. Also, my first thought is that a move like this would pressure white's formation but the more I think about it, the less likely that seems, white's stones are still really annoying even after 10

So I think this is really the only playable move at this point. But even so, I still have to think about the follow ups. If black doesn't respond with 11, I will play here regardless of what he plays I think, even an approach on my bottom left. I think black will have to play here.

The question then becomes whether or not I can play elsewhere yet. My corner stones seem to be getting crowded, but I am not too worried about them I don't think. Even if we exchange 13 and 14, I think my stones are okay and he will probably want to respond after 14.

Nome, Ed:

Pincer on the side instead of defending the corner is playable, though should be 4th line. It is resisting white's plan of making r14 slightly misplaced: now you would rather it were r13 to aim at r8 invasion later. You don't need to be happy with Ed's proposed result as you can play better by cutting and attacking White. See viewtopic.php?p=86322#p86322.

If hidden things are addresesed to me am I allowed to read them now?

So this position gives me a lot to think about (and were at the part of the game where I never really know what I should do :) ) What I'd really like to do is just abandon the top right corner for a play on the left at any of the lettered points below, although I'm not really sure which one I would play. But at the same time the more I look at the board, the more I realize how uncomfortable the top right might become later on, so I have ultimately decided that I need to find a play in that corner.

I considered playing a or b, but I think white can just not respond here and I'll again be allowing my opponent to develop elsewhere on the board with little compensation for myself, so I decided to go for the kick hoping for this sequence. Now my corner seems a little less pressured and if black follows up and tries to make a base for his two stones I can now make my move on the left. Of course, black might simply ignore my move and play elsewhere, but I think this leaves a nicer follow up than a or b would. I know there are still weaknesses in my corner, but I think that is unavoidable for now. I'm also aware that this is probably not a great move, but it seems to me that I should play it now.

Oh, i was afraid of it :) Usually this attaching means that he wants to make my stones heavy and attack them. Moreover, r14 is already in place, so he is strong on the right side, but what will he achieve with this attack?..

I can think now of two answers:
(a) instinctive o16.
Pros: 1. usual; 2. it seems i can aim at r17 later. Cons: 1. if black k16 or something, what should i do? Definitely i don't want to allow him an easy base, so i'll play a pincer around h17. Then it'll be a running fight. Do i like it? I don't know, depends on how it goes. Though i may try to build the left side in process...
(b) planned k16.
Pros: 1. develop hoshi; 2. black o16 - white n17 seems not much loss. Cons: 1. m17? Will it develop into that same running fight? Should i abandon o17 at all and try to build double wing? I like double wing :)

Hard choice...
Well, as for o16. What if black plays f17 then? Unless i pincer, he'll build a base and it will hurt the two stones. If i pincer,

I don't like his wall. Also, my corner is dangerously open. Not a great feeling.

With k16 i may let him have too much... But he already has an extra stone... Naturally i'm feeling behind...

Yes. If a hidden text is meant to be read later, the poster will mark it with something like
"after this corner is settled," "after the mid-game," "after :w50:," or "after this fight is over," etc.

Sometimes, people will also un-hide text, e.g. " :w50: notes unhidden."

If a hidden text is addressed to you but no restriction is specified, then you can read it now.

EdLee, i thought that by default (if no restriction, i.e. nothing is specified) the hidden notes cannot be read until after the game. To let players read them, the poster has to write something like "@player".

That's right. Nome asked (my emphasis):

I see the confusion. I added "addressed to you" in my reply to Nome, thanks. :)

Re: #159 - opex vs Nome

@Ed, Uber:
Thanks for the info, I wasn't sure how that move would play out so I just didn't play it, but it's nice to know that it is playable and how it can be followed up.



So, I have a lot of thought about this position, I don't know which of them, if any, are good but I'll go ahead and write everything I'm thinking about this move.

So the first move I've considered is playing a folow up in the the top right corner because if black plays a, its in a good position with 13, but I think it's to slow for me too play yet, because it's gote for white so I don't think he can come back here yet, so I will just let this area be, especially since I'm not sure how exactly I would want to follow up in this corner. There is also a reduction at b if I am not mistaken, but again, this would be gote for white to fix, so I'm not worried about having to make this reduction yet. So my attention now goes to the other parts of the board. An invasion up top seems premature at this point so I've ruled that out as well, I don't think jumping into a pincer makes much sense with so much of the board remaining open. Similarly, the bottom seems to be much smaller than the left, and as I've said before, I've been wanting to play on the left for a while, so I am definitely going to play there this turn.

My question then becomes whether or not to approach or just take the star point. It's times like these that I wished I studied joseki more often, because then I would feel more confident in approaching.

The simplest approach would just be the 1 space low, but I am pretty sure white would pincer. I don't want to jump in the corner and give white a wall in either direction, so I'd need to jump and this just seems like it's helping black make the top more secure. I don't really want to play this way.

Similarly, if I play the two space, I think white can just back off and be happy and of course the possibility for a pincer still remains.

For these reasons, I'm chosing to just go with the star point for now. It leaves me options in white's corner later, and since it's a 4-4, approaching it isn't my highest priority. I'm also thinking that white might come into the bottom after this move. If he does, I will probably try to force him to settle and give me sente so that I can approach his corner. If he plays a move to defend his corner, I think I'll take a move on the bottom somewhere.

Re: #159 - opex vs Nome

Post by Uberdude »

Argh, black's last move is so bad, o16 only move! The initial p17 kick was somewhat questionable in my opinion, I'd rather simply defend at q18, or tenuki. (GoGoD shows 143 hits for q18 to 9 for p17 for the right hand side shape.). White's k16 also seems a bit dodgy to me, extending is such a nice shape point, and yes black can pincer and attack, but as r14 is low the attack is not so powerful. If white wants to play a fast-paced opening I guess you can't complain that much though. But then black 14 as tenuki means white can play the lovely o16 shape point and thanks to k16 it already has an extension, instead of black pincering. With o16 black's corner starts to feel wobbly at r17. o16 is not just big it is urgent.

So, he prevented my double wing. Now the bottom side seems pretty urgent. Wedge at j3 is not an option:

Next, kakari at f3. I like it if black pincers. But attach seems too powerful.

Black is strong everywhere and is ready to go and destroy white's top.

I thought about often seen in handicap games d7. It may be too adventurous though interesting.

I can play calmly and just defend that weakness from before at o16 (this is a weakness, right?) Black then undoubtedly plays k4, i go for san-san and start reduction. Quite nice? Though i hate to play against big zones... I think i'll try this and hope to learn how to do it properly from comments :)
