FWIW, avalanche was also my first feeling. On the other hand, if black simply plays the usual hane, :w8: might end up looking overconcentrated, which would be a good enough result for black.

I think white can play like this, or maybe even omit the 4-5 exchange (and 8-9), and end up with a reasonable result that isn't overconcentrated, which is why I am leaning towards the avalanche. That said, with the avalanche I would be a bit nervous about white finding a line that allows K3 to shine.

I'm going to avoid the complexities of the avalanche. On the one hand white isn't that strong on the bottom, but on the other hand I know that some avalanche variations can reach to that part of the board. If white can force something that makes his K3 stone look good I could be in a fight without a base.

Besides, this looks good enough. White will either be kept low with a 3-space extension on the third line or, if he plays the high variant, then he'll have a 4 space extension on the bottom. Either he is low and thin or a bit higher and still thin.

I'll play the tiger's mouth variation to reduce the impact of white's 4-4 stone unless he does the descend variant in which case I'll just stay solid.

Sticking to the plan. A part of me almost decided to play the solid way, but I know this is considered proper when facing a 4-4 stone.

To finish the sequence of moves. I'm quite comfortable with my position on the bottom of the board. But I'm definitely going to need to play elsewhere. I imagine :black: will play somewhere near D10 and that will free me up to play elsewhere.

From my understanding this is a classic overplay. If I play here later the potential to cut can cause real problems. However, because I didn't do this solidly it is not as bad for white. Perhaps I should have played solid to make this better...

And now I'm safe to play up here. At least as far as I can tell. :black: still has some weak points that I can take advantage of later.

Not too surprising. I actually expect white to extend toward my side from his corner before doing this, but this isn't a bad move at all. I basically only have this one response since I obviously am invested in the right. If he plays the more modern style we'll see a 3-3 invasion, but I don't think he will. If he pulls back I can approach his corner. I hope he dives for the corner at Q18 so we can play that joseki, but I'm sure he won't.

Hurray! Now my corner is safe and my side is quite a bit safter! All most likely in sente!

What made you choose this instead of alternatives? K16 for example.

Finishing the Sequence.


@Skydyr
This is the move I would normally play here and I believe I've been told K16 was bad. But that could have been more of a situational play.

@hailthorn
K16 as a followup to O17 is perfectly cromulent. It's different from sliding into the corner, though, and sometimes people will confuse the josekis and play K16 after the slide, which is too loose. It basically treats the original approach lightly with the intention of taking the corner if the stone is threatened.


not for players:
I'm not sure if I like the slide here or not. It feels a bit aji-keshi regarding the corner, but black's extension is a bit loose at Q9 so perhaps it's a tradeoff. I'd be tempted to double approach at R12 instead, but this is definitely a chancy play. As white, though, I definitely want sente to take C13. Black taking C14 now is definitely big. I'm not sure it was big enough to take before the top side, however.

This move took a moment for me to consider. I felt like both approaches were fair options. However, I felt that splitting up white was better than just extending my own base because it looks like white gets more out of this exchange.

On the one hand I get a 2-space extension that strengthens the left. However I also have over-concentrated shape and my opponent is looking very strong on the top.

My main concern with this move is if my opponent plays this way:

If white plays like this, the 'a' invasion is just much stronger. A move at 'b' would give white ideal corner shape yet the 3-3 invasion at 'c' would give white a much desired wall, possibly in sente. My objective here, though, is simply to break up the top. So I don't know that I need to do anything immediately with :b21: since the 3-3 invasion and making a 2-space extension are sort of miai for making life on the top to reduce white.

So I will extend up from my group on the left instead and prepare for shenanigans on the bottom if white plays like this.

If white plays the small knight, however, then I will play out the joseki at 'b' because white's corner would be cramped and I may yet be able to harass it.

I considered C14 here as well. But I really like this attachment play here. I feel it works with my stones on the right.

Of course I know this can happen:
