Move 11 at H17 wasn't the most natural move for me... I spent some time coming up with it... I wonder if it's sound. On the following corner (lower right), I spent a lot of time thinking about variations that would result in a ladder if White G16 at 'a', Black G17 at 'b', White tenuki... Move 13, for example, is not one I normally choose, and I often have trouble against it. Yet it seemed to work well here. Perhaps I'll do some more experimenting with that. (I've been fairly disappointed with my results playing the low pincer for some reason... perhaps I'm getting bored with it.) Move 17 took me quite some time to decide on... and move 19 as well. I definitely want to check the sources on this corner.
