The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a classical opening which often features a battle between White's "extra" center pawns and Black's "extra" piece, so it is not surprising that a "hypermodern" response has been developing of late.

11.f4 Kf7
Even the hypermodern strategist has to move a central pawn sometime, and now would have been good: after the game Rybka suggested 11...d5 and after 12.f5 (12.e5 allows the manic 12...d4 13.Qg3 d3 - check it out) Nh4 13.d3 Rf8 14.Qf2 dxe4 15.dxe4 Nexf5 16.exf5 Rxf5 White's center is gone and Black, if anyone, has an edge.

Black also continued without the center pawn thrust in guest1730 [Louis Morin / mrjoker]- guest1656, blitz 2 12, ICC 2001 : 11...Rf8 12.d4 d6 13.f5 Nh8 14.g4 Qd7 15.c4 Nf7 16.Nc3 Kd8 17.b3 h6 18.h4 g5 19.h5 Nc6 20.Ba3 Qe8 21.Rad1 Kd7 22.e5 Nfxe5 23.dxe5 Qxe5 24.Qd3 Rae8 25.Rde1 Qd4+ 26.Qxd4 Nxd4 27.Rxe8 Rxe8 28.Bb2 Nf3+ 29.Kf2 Nh2 30.Rg1 Bf3 31.Rg3 Bxg4 32.Rg2 Bxf5 33.Rxh2 c6 34.Kf3 Rf8 35.Kg3 Be6 36.Ne2 c5 37.Bg7 Rf1 38.Bxh6 Ra1 39.Nc3 Rg1+ 40.Kf2 g4 41.Kxg1 g3 42.Rg2 Bg4 43.Rxg3 Bxh5 44.Ne4 Kc6 45.Rg5 b5 46.Rxh5 bxc4 47.bxc4 a5 48.Bf4 a4 49.Rh6 Kb6 50.Rxd6+ Ka5 51.Bd2 checkmate
12.f5 Ne5 13.d4 Nc4 14.Qf4
The battle of pieces vs pawns is very clear.
Black might have taken advantage of the opportunity his last move gave him to play 18...Qh4, as after 19.Qxh4 Nxh4 White has to slow down his pawn roller with 20.d5 and play positionally; or support it with 20.Rae1, and watch it be destroyed, as 20...Ba6 leads to active play and an even game, e.g. 21.Rf4 Ng6 22. Rg4 Nxf5 23.exf5 Rxf5.

19.f6 g6
Here my opponent decided to give the piece back. More in line with his hypermodern play would have been 19...Ng6 (again; Nimzovich would have loved it) 20.e5 c5 when White would destroy his own center and the game would become quite unclear after 21.exd6 Rxf6.

20.fxe7 Qxe7 21.Rae1 Rxf1+ 22.Rxf1
Now White is a pawn ahead, but Black can continue to induce complications after 22...Qe6, un-pinning his Knight and planning to pile up further on the e-pawn. Rybka suggests that White then swap Queens and exchange off Black's Knight: 23.Qxe6 dxe6 24.Bxd6 cxd6.
analysis diagram
It will be a long time, if ever, before White can make something out of his extra pawn.
One more point: if after 22...Qe6 23.Qxe6 dxe6 White tries 24.e5 instead, the Black Knight dances with 24...Nf5 and the pressure on White's center is intense.
22...Nxe4
Celebrating too soon. Yes, the e-pawn is attacked 3 times and only defended 2 times, but White left it to "hang" because one of Black's attackers was pinned to the other.
23.Bxe7 Nxc3
Black has played well and doesn't want to give the fight up yet.
I set my sights on checkmate.

I take my hat off to jdvatty for a fascinating game!
