I wanted to take A14 in sente first, but if you responded with B18, this 31 no longer seems sente. This move is sente because it threatens to take B18 myself. What do you think, is this enough opening for our purposes, or would you like to keep going until the big points on the bottom and left are taken? I had originally estimated 30 moves as a reasonable approximation of the big opening, but it's up to you.

Sounds good. But do you mind if I just see how you respond to this? And even if my reading is right, this move seems troublesome, but it would probably be my move in a real game so...

Oh, good catch. I guess it's a ko. Not that I mind losing the stones in the corner, as I'd meant to sacrifice them in the first place. So I guess it's kind of a picnic ko? I would probably play the ko but aim at playing 'a' if possible.

edit: And it looks like Araban beat me to the punch of showing the ko. =)

Well going a little further was to give D13 an easier time being pulled out just in case. But I think your move is better...thank you! Very helpful post

I think this is enough for going further this game Thanks!

No problem, thank you very much for going over this opening with me. I'll go back through and see if I have anything to add. As far as your most recent comment: I wouldn't worry too much about pulling out D13. There's a difference between a useful cutting/territory stone and a stone just splatted against an enemy wall. Unless you think you can actually get my whole wall under severe attack, it's not worth saving your single stone. Much better would be something like c9, to build a framework with your bottom left and prevent me from making as much use of my wall to build my own.

And for what it's worth, before Araban pointed it out, I wasn't aware of how serious the aji behind that jump was, in this case.

Thanks to Mezz and to all of the observers! Mezz, I feel like I may have learned more than you did! I should probably go study some wide-approach joseki...
