A few days after posting on the Jerome-ish 1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 4.Bxf7+ (see "Offside!" and "The Other Side") I discovered that a similar line of play from the Vienna Opening rather than the Italian Game (a reminiscent reflection of "Godfather of the Jerome Gambit?" Part I, Part II, Part III and Endnote) – 1.e4 e5 2.Nc3 Nc6 3.Bc4 Na5 4.Bxf7+ – had been addressed in a "Reader's Challenge" at ChessPublishing ( http://www.chesspublishing.com/content/1/puz2.htm):
Reader’s Challenge P2.1.1
referring to M.Adams-P.Motwani, London 1989
The idea of ...Na5 has been mentioned, but would it have been OK for Black to play it even earlier, at move three?
Solution
3...Na5? loses to 4 Bxf7+
! Kxf7 5 Qh5+, intending 5...g6 6 Qe5 (forking the loose black pieces on a5 and h8) or 5...Ke6 6 Qf5+ Kd6 7 d4 and then, for example, 7...Qf6 8 dxe5+ Qxe5 9 Bf4 or 7...Qe8 8 dxe5+ Kc6 9 e6 b6 10 Qd5# or 7...Nc6 8 dxe5+ Nxe5 9 Bf4 Qf6 10 Bxe5+ Qxe5 11 0-0-0+, costing Black his queen.
It's pretty easy to back this analysis up with games, as I have only a handful in my database:
