Alex: This page needs some content. I've had this played against me a few times and never seem to get quite the result I'm hoping for. Here's the most recent game in which it came up.

White plays aggressively  

Alex: Ater messing up a joseki in the lower right and letting me get a massive corner (albeit in return for not-insignificant thickness), White plays honte with W1 then attempts to get back in the game with W3 when I slide to B2. I was afraid of being left eyeless in the face of that massive wall, so I grovelled for life in the corner and ended up granting him a huge centre. I went on to win the game, but I felt that it was a tougher game for me that it should have been if I'd handled W3 better.

Is W3 a reasonable move for W in this position, and how should I have played? It attaches to a weak stone, so should probably not be right, but it does lead to complications...

LukeNine45: I know I've seen W3 in a pro game (can't remember which one), so it must be possible in some circumstances. My impression was that its purpose was to build some thickness to the right. It looks wrong to me in this game because after something like Black a or b the thickness will overlap with what white already has and hence be over-concentrated. But I don't really feel qualified to comment since you're a few stones stronger than me...


Bill: I don't really know what's best, but how about this line? After B4 I don't think that W5 at B6 would be good because of overconcentration. (Black will respond at a.) If B6 is at W7, White plays atari at b and the resulting fight looks disadvantageous for Black. After B8 Kitani and Suzuki's Small Joseki Dictionary says that this is an even exchange, but in this case Black's ponnuki is stifled by White's thickness on the right, so maybe this isn't so good for Black.

I don't know of anything better for Black, so maybe W3 is fine, and B2 is not so good. (Should B2 be at c, as a probe?)

Alex: Well, if Black's ponnuki is stifled by White's thickness, surely White's thickness is significantly reduced by Black's ponnuki, no? I'd take this result, especially since my bottom right corner is so large... I think I could win this game.
