It would have been appropriate then to have mentioned a related game and analysis by Francesco Recchia of Italy that had been posted to this blog a year and a half earlier in "A Kind of Jerome Gambit That Wins".
Here is the earliest example that I have found of the opening variation.
Hahlbohm,H - Moorman,L
Chicago, 1917
1.e4 e5 2.Nf3 d6 3.d4 Nd7 4.Bc4 h6 5.dxe5 dxe5 6.Bxf7+
6...Kxf7 7.Nxe5+ Kf6 8.Qd5
Instead, Kosteniuk chose 8.Qd4. Recchia energetically recommended 8.Nc3.
Now 8...Qe8 is Black's only move.
8...Ne7 9.Qf7+ Kxe5 10.Bf4+ Kd4 11.Qe6 Nc5 12.Be3 checkmate
After posting this, I hoped to try the line in a FICS blitz game. I was not able to reach the exact position, but I put the lessons that I had learned to good use in perrypawnpusher - NN, blitz, FICS, 2010: 1.e4 e5 2.Nf3 d6 3.Bc4 h6 4.d4 Nc6 (4...Nd7 would reach Hahlbohm - Moorman, above. Best was 4...exd4) 5.dxe5 Nxe5 (5...Bg4 is an interesting gambit; otherwise, 5...Qe7 seems necessary) 6.Nxe5 dxe5 7.Bxf7+ Kxf7 8.Qxd8 Black resigned
