We can get further out first. We give up some profit in the bottom right, but after our group is safe on the bottom, we can look forward to a double approach on the top. No matter what we do, we're not going to get a locally good result somewhere, since we allowed for the double pincer ...

In reverse alphabetical order:
h: Changes direction. However, the black stones on both side are low. This isn't the fastest place for development.
g: This is the fastest way to settle in the corner. However, even if black gets another stone in the area, our stone has options.

This does not seem too unreasonable for us. Thus, I'm not afraid of tenuki from the bottom right.

I'm not that big on this option. It seems like something like this is unlikely to turn out well. While there are certainly variations, it seems unlikely that we'll stabilize enough to strongly counterattack before B is also stable.

After the exchange of 1 for 2, I can't see a sufficiently compensating attack on the bottom right black stone. I am concerned that, after we force B to settle on both sides, we could end up on dame, with our without life.

This option is good, but slow. Forces black to take a good point on top, which also makes a double-approach less appealing.

This isn't bad, but it may help B solidify the right side too much. Let's look at other alternatives.
b: As previously mentioned, I like this move, but am concerned that the marked black stone is close enough to disrupt its effectiveness.
a: Simple, stable. If B falls back defensively, we get the chance to make our own big move on top.

I like this move, because it pressure the black groups on both sides. It seems likely that we're going to get to get to attack either the marked black stone or the top right corner, depending on where B defends. If we play all of a sequence like this, it seems we end up more efficient. We have thickness, our top left is as big as anything black has, and our stability is just fine. While this followup is pie in the sky, it demonstrates that in hte opening, keeping stable groups helps to make better followups available. For example, when black's 1 makes the top look more appealing to them, we get to deny it because our group below is stable for the moment. Similarly, stabilizing our right group means that we can do what is required below, while worrying less about hurting the group above. It's not flawless, but I think that currently, taking this move is the best option I see.

I choose R10.

Whoops, sorry. I forgot that that one was taken. Perhaps I should not try to make my moves while I have a headache and don't feel great.

Having embarassed myself, I shall simply congratulate you on what I think is good judgement, and take my other choice, O17, instead. This lets us focus on making a big top. If we get a big top and stabilize either stone on the right side, I feel like we can be content. O17 works well with the majority of the rest of our stones.

For teammates and observers:

@P4 (red's move)

I'm really not keen on this. I was hoping that the continuation request would show some of your thoughts that perhaps I hadn't considered, but even the final position looks really difficult for White to handle to me. For example, if White tenukis:

White is just in so much trouble - it's a complete disaster. Of course, White won't tenuki, but we're going to have a group running away on dame while Black's picking up all his points on the bottom. I think White will quickly fall behind here.


@O17 (chew's move)

Actually, I quite like this idea. I want White to develop the top, and this will help, whilst at the same time treating everything lightly. There's the 3-3 in the top right still open, and still not yet any decisions made on the appropriate followup in the lower right. My concern, and the reason I chose not to go for it, is the ability for Black to attack R14 while gaining stability on the right side, which has the knock on effect of enabling Black to start attacking R5. It feels like a chain of events which favours Black to me, so I'm deciding against it. Was very tempted though!


@R11 (TJ's move)

Ok, we're going with this one. Firstly, it leaves O17 as a much more severe attack now, and gives White some really good prospects on the top and upper right. Secondly, it destabilises Black's pincering stone nicely. If Black has to worry about that stone, he can't attack either White stone properly, which means it indirectly helps R5 to keep off the hook for now. If Black jumps out, I think White needs to really think about the lower right, and I encourage a broad range of options to be considered with regards to the best way to do this (for example, see some of my last suggestions, and both chew's taisha and red's press are obviously also typical shapes - that gives 6 local moves to consider without including any possible tenuki based ideas).


To the whole team only

Please can we include variations in most of our suggestions, including a brief summary of why we like the end result? It makes it much easier to know why the move suggestion is being made :)


To observers only

This was the first move I wouldn't have personally chosen or played in this given situation. There are a few reasons for this.

For me, "a" represents aji and interesting points for the top right White stone, and "b" points do for the lower right stone. Now, 4-4 stones are naturally flexible, and both approaches and followups have a tendency of having a lower urgency to begin with. Particularly O17, R17 and R11 are all sort of miai points, and therefore they are relatively easy to leave for now. If Black defends the corner, we play R11, if Black plays R11, we either O17 or R17, that sort of thing. As a result, I feel that whole top right corner is relatively non-urgent.

The lower right however is a different kettle of fish. If Black gets a followup here, particularly moves such as Q5 (although R4 may be effective at a pinch now) it's much harder for White to find a good response that doesn't give Black good compensation. As a result, I really wanted to play there badly. I don't like jumping out or the press (for reasons given in red's response), and the contact at R3 seems rather aji-keshi, designed purely to settle in the corner:

I think Black can get a good result from this far too easily - for one thing, taking sente to play a move such as R11 himself.

A joseki I like (normally with the Black pincer high), was what I was really hoping to get the opportunity to play, but despite my subtle hints to look at the corner in greater detail, no-one actually seemed to consider any of those moves :P It plays out as follows:

White can now settle in the corner with "a", and also has the beginnings of a good position at the bottom. The right side is still wide open, and the top right corner can be dealt with in a variety of ways. I was very pleased with this. However, look at the following:

This looks awesome to me, although deciding between "b" and "c" after Black extends from White "a" is difficult for me to read out. If Black does jump out, this joseki gives him no bang for his buck, which means he's going to have to deviate. That's not hard for course, as :b13: is only one option, but anything else makes a base on the lower side very easy, and there's still a large amount of corner aji to reduce his territory later. If we can find this move, I'll feel White may be edging the upper hand, but until then I consider it a) even, and b) very volatile.

Topaz:
... Can you please show a diagram where white doesn't tenuki? Yours right now just shows that white would have to settle after the one point jump, which doesn't seem so bad given that black has zero eyes in the middle, and a double approach on the top right is imminent.


For observers only:
I very much dislike my team's approach to the fuseki thus far. I don't like how from the very beginning we've been trying to shake things up and play nonstandard fuseki (i.e. the 5-3 move two is a non-orthodox move). We claimed that we'd play a fluid style, foiling black's plans. Instead we seem to be playing an amateur version of amashi, and just gallivanting all over the board. We'll have to pay our due sometime. We're white; we have komi. We don't need to shake things up like this.

Response to red (and presumably the team?)

I'm unsure what you are asking exactly? If White doesn't tenuki, because of the thinness in the shape, it feels White will have to be running, and won't have time to turn and attack the right hand side stone. We can try to cap, but with the jump out Black is relatively strong. Something like this ?

I agree we have a double approach looming in the top right, but the important move that makes that big is R11, and the initial press is unnecessary. Here, if White double approaches the top right, Black can carry on building up points at the bottom, and I don't see what White's compensation is. With the move we have selected, we still have that double approach to play, and we also have more options in the lower right than just pressing down.

I would like to see how we can continue from your diagram without creating a heavy group, but I can't work it out myself. It's possible you have simply read something better than me, but as you haven't displayed it, I can only go on my evaluation of the position you've presented and any alternatives to tenuki that are immediately obvious to me.

Also, in fairness, I can only go with the options I have, and my personal choice was none of the three :P


Addendum (also to red and the team):

Of course, if Black jumps out, your variation is still playable. So if a viable attacking sequence can be put forward, it's still the direction we can take the game. If Black tenukis, for example to defend with O17, then your lean makes great sense as we can cap to great effect. However, because we don't know if we want that yet, playing it too soon simply feels like it restricts our options without any immediately obvious return.

I was looking at the peep to settle our stones a bit. We don't have a good attack on these stones, but they do need to be kept in mind for later. However, I wanted the clarification for purely logical reasons. You did not show my sequence was bad (which I now feel it is. I didn't put much thought into the press.) You showed that tenuki after the sequence was bad.

On the whole, I don't really like how thinly we've been playing on the right side. This is very much not my style of play, which makes my suggestions useless in the fuseki here.

Response to red (and for the team if Red is ok with this discussion being a team one?):

Ah, I apologise, I will try to be more clear about further explanations for rejecting moves in the future.

We do have that peep, but it feels like aji-keshi. Peeps because we are worried about our own safety always make me more uncomfortable than peeps that we may use to make the opponent heavy or steal eyeshape. Of course it will help fix our cut issues, but the cut doesn't work for Black anyway just yet, and if we ever hope to attack those stones we don't want to make them any thicker. I'd rather see what Black does in response first. Please have a look at my addendum on the last post - one sequence to aim at is as follows:

I'm genuinely not saying the press is inherently bad, but coupled with R11 later I think it will be. It's possible we could press and then cap, but as Black can play R11 himself it doesn't look like we can launch an attack that way.

FWIW, I don't consider our play on the right thin. To me, one stone is never thin, the worst it will be is aji, but a single stone is not committed. The idea of keeping them both alive is only one of the available options :)

A-E seem to be the choices in my mind... with c and d having the option of extending one more point to the left...

I think (e) is still premature... (a) would be my first choice...

Move B is optimal if white takes the passive approach and tries to extend their current base... if they take the aggressive approach and play :w2: at :b3: then this move is not advantageous to black...

Maybe something like this? But I just don't see it going as great as if black extended the pincer stone first....

If we're going to play b (or a) we should exchange :b11: for :w12: first. White wouldn't slide into the corner if we played b directly; they would leave the corner open for invasion.

Kicking makes white over-concentrated, though I'm not sure it's the best move. The side stone or the lower right might need attention first.

To observers:
I'm glad to see that Fwiffo is thinking about kicking. I think that it may be our best move because the slide underneath is sente for them.


I see lots of white internal chat AFTER the move. That is a sign of dissent in the ranks. Has Topazg resorted to floggings yet?

If we're going to play b (or a) we should exchange :b11: for :w12: first. White wouldn't slide into the corner if we played b directly; they would leave the corner open for invasion.

Kicking makes white over-concentrated, though I'm not sure it's the best move. The side stone or the lower right might need attention first.


I am not sure white has to respond to your attachment that way... i think white can play B first instead and still be able to live on the side... putting black as a bigger disadvantage than if black played B first...
I'm thinking...

To observers:

I tend to agree with Fwiffo.

This allows white to live comfortably:

Now 'a' looks like sente to hurt the 3-stone white group.

Ultimately, the relevant issue is not so much whether white is comfy or not, it is whether or not we can afford to give up sente. Even with the better of the two moves, white can still play a series of forcing moves along the bottom:

Maybe black can play 8 at 'a', but either way the lone black stone is unhappy. If it can claw its way out, perhaps it becomes a killer, but if not, it will scramble to live small in gote while white probably connects his two groups on top of it.

Just want to say I'm enjoying the commentary, keep up the good work! I think everyone approaches the go board a little differently, and the discussion is quite interesting.
