So I shouldn't have tenuki'd the top left so soon I think.
I think I was behind after that, but my opponent let me chase his weak group all the way across the board.
Really I'm looking for analysis about the middle-game. I think I understand most of what went wrong and right in the early game, but, of course, tips are appreciated.
Oh, J14 is probably going to look weird. I realized it was kind of a mistake as soon as I played it - me letting him connect back was just me making the most of the situation.
