AYD game 2

I won my AYD game against Andrew last night.

I screwed up a shape that I know:

I know this!  But for some reason I blanked when White captured.  Black can play A, but I chickened out and played B.  Part of it was a lack of confidence.  But part of it was also that I didn't want my stones in the middle to get attacked.  But In-seong says because Black's head is out to the center, White can't do much there anyway.

Apparently, I don't know that shape as well as I thought I did.  But Guo Juan has a pair of Lunch Special lectures on it, with problems!  So I'll know it much better soon.  :)

Here are a few more comments from In-seong on my game with Andrew.
