The following blitz game allows me to comment on a rare Jerome Gambit line (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 h6 6.Nxe5+ Nxe5 7.Qh5+ by transposition) and an improvement for Black that has yet to be played, despite its mention here. perrypawnpusher - Duwasi 10 0 blitz, FICS, 2016 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 The Semi-Italian Opening. 4.O-O Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit. 5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6
Black's best choice is 8...Bf8, as the Rook is then off-limits - 9.Qxh8? Bg7 10.Qh7 Nf6 and Her Majesty is doomed. White does best with 9.d4, but after 9...d6 10.Qb5 c6 11.Qd3 Black is better. It is possible that Black's move in the game - and the Rook sacrifice - was prompted by some knowledge of the game Amateur - Blackburne, London, 1885, but the addition of ...h6 and 0-0 in our game makes a big difference. 9.Qxh8 h5 10.Qc3
Quickly extracting the Queen, and unnecessarily so, as safety was no longer an issue. It was wiser to play 10.d4 Bb6 11.Qh7+ Kf8 12.Bh6+ Nxh6 13.Qxh6+ Kf7 and gain some more material. Still, White is the exchange and a couple of pawns ahead, and plays it safe the rest of the way. 10...Be6 11.d4 Bb6 12.d5 Bd7 13.Qf3+ Nf6 14.Bg5 Bg4 15.Qxf6+ Qxf6 16.Bxf6 Kxf6
I think Black played on because he was ahead on the clock and I was playing in an uninspiring manner - a reasonable idea, although, in this case, an unsuccessful one. 29...a6 30.Rf1 Bxd5 31.Rh8 Kxe6 32.Re1+ Kd7 33.Rxh4 Kc6 34.c4 Be6 35.Rxe6 b5 36.cxb5+ axb5 37.Rb4 Kc5 38.c3 c6 39.Ree4 d5 40.Rh4 Kd6 41.g4 Ke6 42.g5 Kf5 43.Rhg4 Kg6 44.h4 Kh5 45.Kg2 Kg6 46.Kg3 Kg7 47.Rbf4 Kg6 48.Rf6+ Kg7 49.h5 c5 50.h6+ Kh7 51.Kh4 d4 52.cxd4 c4 53.Rb6 c3 54.Rxb5 c2 55.Rg1 Kg6 56.Rc1 Kh7 57.Rxc2 Black resigned
If more people read this blog, I would lose more games. As it is, my opponent in the following game missed out on a chance to spring an interesting trap on me. (No, I'm not going to call it the "Kennedy Defense in the Semi-Italian Jerome Gambit".) perrypawnpusher - Entangle blitz, FICS, 2014 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

4.0-0 Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6 8.Qxe5
The addition of ...h7-h6 and 0-0 to the regular Jerome Gambit position renders 8...d6, as in the Blackburne Defense, and 8...Qe7, as in Whistler's Defense, ineffective.
As discussed in "I have a win, but it will take time..." and "By the Numbers", Black's best move now is 8...Bf8!? (introduced in these blog pages 4 1/2 years ago), as 9.Qxh8 would then be an error because the Queen would be trapped, and ultimately won, with 9...Bg7.
The Database has yet to see one example of this defense.
8...Nf6
Black rightfully does not want to lose the Rook, but this move returns the second sacrificed piece.
I've been having second thoughts about the accuracy of my strategy against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) cousin: Jerome-ized play against the Semi-Italian Opening, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 (my choice)Bc5 5.Bxf7+.
Recently, I've collected 138 games which suggest the brute-force method of "no waiting": 4.Bxf7+, anyhow. At first glance, however, that seems a bit blunt to me, even if it's perfectly playable in lightning chess.
Just like with the Jerome Gambit proper, there has developed a "modern" treatment of the Jerome-ized Semi-Italian opening, one which does not include 6.Nxe5+. Several games in the current Jerome Gambit Thematic Tournament at Chessworld have developed that theme:
White's position is so overwhelming, he even had Bf4 on this move or the next. Instead, he captures more of Black's army, and that works just fine. 22...exf3 23.Qa5+Kc8 24.Nd6+ Kd7 25.Nf7+ Ke8 26.Nxh8 fxg2 27.Qxh5+
Now Black has some hope of hanging on a bit longer with 27...g6, but decides instead to end it all quickly.
Black is surprised, and makes a poor response. 
Black has some open lines (that he has purchased with his pawns) which he can place his Rooks on, but they are not adequate compensation.
