Interesting Position

After reading about how Fischer at one point said that some of his most interesting games were the ones he played against himself, I've been trying to play against myself. I find his statement rather arrogant, but I decided to give it a try just to see - in my opinion, it's dreadfully boring, probably because I'm still a beginner.

In any case, this position has arisen where I thought Black had the obvious advantage, and now I'm not too sure. Feel free to comment on the position (I'd give it a -0.5 or so), and also what lines you see as being best play for both sides.
