Jerome Gambit: Over Time, You Learn A Few Things

I checked - fehim's games in The Database go back to 2005. Over time, he has learned a few things about how to play the Jerome Gambit. The following game shows White's attack following Black's King across the board.

fehim - Tomalak
3 0 blitz, FICS, 2019 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6 

This position can be found in 23 games in The Database, with White scoring 78%. Black's move is not bad, but it certainly encourages f2-f4, with the threat of f4-f5, which had to have been encouraging to the first player. 

10.O-O N8e7 11.f4 

This is an improvement over fehim's previous game with the line: 11.d4 Kd7 12.f4 Bc4 13.Re1 Kc8 14.b3 Ba6 15.a4 Rf8 16.f5 Nh8 17.b4 b6 18.a5 Bb7 19.c4 Nf7 20.Bb2 Re8 21.Nc3 Nxf5 22.Qh3 g6 23.exf5 gxf5 24.Qxf5+ Qd7 25.Rxe8+ Nd8 26.Qxd7+ Kxd7 27.Rg8 Ne6 28.Rxa8 Bxa8 29.d5 Nd4 30.Ne4 c6 31.Bxd4 Black resigned,  fehim - ReyanshiKhatrim, FICS, 2018. 

11...Bf7 12.d4 Kd7 

Black's attempt to castle-by-hand on the Queenside is an unorthodox response to White's growing pawn center. 

13.f5 Nf8 14.Qh3 Kc6 

Black's King is uneasy about the possibility of a discovered check from f4-f5, but this move is risky. Better was to skulk back to the center with 14...Ke8.

15.Nc3

This is a reasonable move, although 15.d5+ would have been sharper.  Komodo 10 opines that Black would have to return a piece, then, with 15...Bxd5, when White would clearly be better.

The game now drifts toward equality.

15...b6 16.Qf3 Kb7 17.e5+ c6 

18.e6 Be8 19.Be3 Rc8 

Black's move gives White ideas. Better was the consistent 19...d5.

20.a4 Kb8 21.a5 c5

This allows some opening of lines. Instead, hoping to clog things up with 21...b5 was a better choice.

22. axb6 Qxb6 23.dxc5 dxc5 24.b4 

24...Bc6 25.Qg3+ Qc7 26.Bf4 Black resigned
