How would you exchange my knight and rook for the half-duck? After you take the bishight, I take the half-duck and none of my pieces aside from that one pawn are in immediate danger. You'd probably then move your chancellor to d5, and I'd be in big trouble then.
I think you're right though, and since I don't stand a chance without taking back my Pxf4 move, so I'm replacing it with B-e6
