We can not sacrifice the two stones. Cutting @D13 seems to be another possibility, but it leads to very complicated variations I can not read accurately.

We can not sacrifice the two stones. Cutting @D13 seems to be another possibility, but it leads to very complicated variations I can not read accurately.

I also vote for this move. Here are some variations:

Black is screwed as far as I can read

The cutting stones are heavy, and they need to come back and settle the corner.

Do we now play some move to make something out of our outside stones, or meekly defend against a white play at a? Are we even alive without defending against a?

Posted: **Sun Mar 27, 2011 6:45 pm**

So, i guess we might as well force a few times to strengthen the aji of these stones

AFter this, I think we should try to make a move which counteracts whites thickness, makes some point and makes use of the new aji, so I suggest:

The obvious problem with this move is it really doesn't make that many points since it can be easily undercut by white's thickness. This is just an idea though.

That does seem to be the most important question.

Both 55 and 57 seem like good ko threats to me. Are we sure we want to play them now?

Also, it may not be the best direction for those stones, whether it be now or later. If we ever get the opportunity to run as shown with the marked stones:

Hey Joaz (and Joaz alone, and also I guess observers);

I`d appreciate it if you`d explain a bit about the last few moves to me.

I am under the impression that, with the result you have now, you (and your team) are unhappy with the board as black ?
