C20: King's Pawn Game: Leonardis Variation

Apparently it is a variation of an Open Game variation called the Leonardis/Clam Variation (saw both names, not sure which it actually is).  It looks playable, but I would rather play it after 2.Bc4 and THEN 3.d3 in the main lines of the Bishop's Opening with a delayed f2-f4, as the bishop will most likely be very awkward in your position.
