=== Discussion for black 24 ===
[daniel the smith] ''a'' is what leaps out at me.
[Dusk Eagle] ''a''.
[JoazBanbeck] It leapt out at me too. Fortunately, I had the presence of mind to duck.
If 'a' is really needed, let us play 'b' first. He connects, then we play 'a'.
[daniel the smith] Is that aji keshi? You don't think we'll ever want to cut at ''i''? I'm thinking about it...
[Kirby] I haven't thought it through much, but I wonder if 'c' is OK...
[daniel the smith] Hmm... if black ''c'', white will ''d'' (white ''a'' looks awful for white)-- looks better for white to me. So what about black ''d'' directly? Then I guess white ''c'' and that doesn't look good for black at all. I'm still thinking ''a'' is best.
[Kirby] Yeah, maybe 'c' is too aggressive. When I do try to read it out, it doesn't look great for us.
[topazg] 0.7 for 'd', 0.3 for 'a'.
[Kirby] What's the sequence you have in mind if white plays 'c' in response to 'd', [topazg]?
[topazg] I'd then connect at 'a'. If we are going to do it anyway, I'd rather White doesn't get 'd'. It's not like the ladder works for White, so he has to allow us to capture his last stone. Either that, or he allows us to squeeze, which looks really bad for White.
[daniel the smith] Added a couple more diagrams. I'm 1.0 for ''a'' still.
[Kirby] I am starting to think that our last move was a mistake, too. I don't know how to fix it easily. I will vote 0.5 for 'a', 0.1 for 'b', 0.1 for 'c', 0.1 for 'd', and 0.1 for 'e'.
[Kirby] I'm still not sure about the best way to play, but one thing to consider is that, if we play 'a', Magicwand will probably fix. We could try to take the opportunity to cut our local losses and proceed to attacking the two top white stones, like we wanted to awhile back. The bad part of this is that it probably ensures that our previous move was a bad one (unless we can work something up later).
[daniel the smith] I still think ''a'', he fixes, we cut at ''i'' is best.
[Kirby] I'll switch to 1.0 for 'a'. I'm not sure about the followup, yet, because it'll depend on what he does.
[topazg] Let's go with 'a' then, it definitely looks like the most reasonable move, although I'm 90% sure that makes our last move a mistake. We're going to end up with a single weak Black group floating around White's groups (one of which will be completely settled with points, so it's not even 1 weak group against 2), and we'll have lost an unpleasant amount of our corner investment. I really don't like the cut at 'i' now, as White can sacrifice those two stones quite easily. It's like 5-8 points or something, probably in gote, for us to cut there now.
[JoazBanbeck] I realize that Daniel is probably right: 'b' is aji-keshi. I could settle for 'a'.
----
[daniel the smith] Next move for black? Looks pretty bad to me...
[topazg]I've added the continuation I was expecting. I half want to play at
right now, but I think we've got to look after the corner, or what we were doing for the last 5 or 6 moves?
%%%%
[daniel the smith] I'm pretty sure I greatly prefer this; white is not nearly as thick, we have sente (white has to do something to control that cutting stone), and the cutting stone will still have large amounts of aji.
%%%%
[daniel the smith] Here we still have sente, but white is much thicker and I'm not sure that B1 is worth that. If we aren't careful it might even become a target.
[topazg] As long as we extend at 'n' instead of the atari, I'm happy with this - 'h' last move feels like a mistake now though, unless we can start some pretty serious attacks going. White can settle in a move on the left, so we must split asap.
