OTB: Ruy Lopez - sharp game

Quite a weird game - unusual opening, quite a few missed opportunities on both sides.  My opponent recorded his moves on an IPad and kindly emailed me the pgn afterwards.

I think I got a bit complacent early on, but still not quite sure how i should have played at move 9 - it got very sharp and unforgiving and left me a pawn down when I thought I had got it sewn up.
