Who can guess the opening?

HINT: I feel so vindicated, because everybody always tells me I shouldn't play this rubbish :)

Ruy Lopez, Schliemann Defence.

Yeah, see, it's a sound system

I have had White against the Schliemann three times in my career, with the score being 0W, 3L.  I'm now playing the Vienna and Scotch Gambit--they're a lot more fun.
