That it forces me to study the double approach is precisely one of the reasons I like .

I'm defending my bottom group while scrunching him in. He'll take the corner and attack my stone most likely. Any other sequence where I started from my approach stone means he'll pincer my bottom group and use that one stone to unlock annoying aji.

This was my plan, I figured he wouldn't play one space further along the bottom, and this makes my shape stronger for the counter pincer here. I think black is slightly better now.

I'll move that lower right stone out later, for now, the top is the largest side.
