I like Chew Terr's move next, though I would play it on the right hand side as this is a tenuki and shows you're not just following White around!
I also like Joaz' move, maybe even at K9 would be interesting, but I doubt I'd play either in a tournament.

So far, the game seems to make sense. I'm expecting a high approach to the top left corner most. I imagine one-space, keeping things fairly normal but doing it in mostly-sente.

Also, thanks Tooveli, good to know my move wasn't too crazy. I do like your metagamey idea of changing sides for purely nonpositional reasons.

White :w6: approaching the top left to avoid that black takes both corners with extension options on two sides as well as b (3 great follow-ups)
Black :b7: black still takes the corner like this. A pincer seems wrong because P17 is low
White :w10: this joseki makes sure black does not get the two space extension at a in snete
black :b13: black gets sente from the joseki and can make this nice side extension.

freegame: Thank you, your explanation of :w10: is helpful. The rest is the sort of thing I would have predicted, but it is good to see the hanging connection with the proper reason.

There are two regions to think about: top left and the right side.

In the top left, White, upon approaching, does not fear a pincer from the top side, as Black is low there anyway. Furthermore, White is not very interested in central influence. Therefore, a low and near kakari seems natural.

On the right side, White is not too focused on a close connection to his strong lower right stone, so extending as far as possible, while keeping the option of further extending, seems sensible: I would play R11 here.

Of these two options, I think that the kakari is a bit bigger, so I would play E17.

I don't think this is as bad as it looks, black doesn't seem to be able to attack anything too strongly to handle. It's sticky though, so of course white could just make the solid connection to avoid it.

Or play the avalanche, which is more fun :)

This is an alternate followup. I don't know if it's better or not. I know that as B, I'm not sure I'd be thrilled with the position of 6.


Also, I second moving this thread. I'm enjoying it, but when I first open the forums, I'd like to know whether the rest of the professionals forum has been updated or not, since this thread will almost always have new posts.

I dithered about where to put this thread and finally settled on this forum because the description for it included "analysis of professional games". But I agree that this is sort of a different case, especially if it ends up getting hundreds of comments (and I'm very pleased with the number it has already gotten!). I'll ask an admin to move it to Study Group.

R11 seems very natural to me. The obvious choice is either R11 or kakari.
If White approaches the top-left first, Black can find a way to get sente and then take the big point on the right. By taking the big point on the right it seems that you can either get both or force Black into the following, which looks good for White to me.

Fuseki is definitely the weakest part of my game. I'd be interested in others opinions on my thought process.

Edit: Hidden the diagram as that seems to be the trend in the thread. I'm not sure why though. The only thing I can think is it makes the actual game posts easier to find/follow.

Right, the reason I hide diagrams is, it makes it easier to pick out the real moves at a glance, as well as saving vertical scroll-space.

This move 6 is the boring variation.

my thoughts
I posted this at move 4 already.

I would now take the other corner.
I would go for a high one facing the low P17 stone, but a low one seems fine too
White will than likely play something like :w8:

My guess would be somewhere in the bottom center.

yes bottom center seems the only place. I would go for a low move (K3) to have easy follow-ups to make a base.
If black played anything else white will play the bottom center (or pincer in case of an approach) that puts white in a good position to take a lot of solid points while attacking black.

It still seems quite even to me. I would be satisfied with both black and white.
though if I had to pick a side I would go with black for 2 reasons:
1: If black now gets a move in the bottom center black gets an easy group on the bottom preventing white from getting an attack or a lot of solid points.
2: for now it seems like there is not much fighting going on. in case of no fighting and relatively big areas with points the komi white gets "feels" less. In a game where there is a lot of fighting and small areas the komi white gets adds up to a bigger percentage of the total points.

looking ahead:
If black takes the bottom white will most likely approach that stone.
I would do so from the right bottom, because the R11 stone is further, meaning there is more to gain in the bottom right part of the board, compared to the bottom left (very small difference)
If white does not approach black gets to approach one of the corners and have nice support from the bottom center stone, making it easier (more likely) to end the joseki in sente.

Where? :)

I'd prefer it for people to make concrete suggestions; often picking an exact point is the interesting part!
