The "Jerome pawns" - the one White obtains in exchange for his piece(s) - can be a powerful attacking or positional force. However, if White does not take care of his pawns, they can also become targets and the cause of his downfall, as in the following game.
ulla - abebe
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+
The Blackburne Shilling Jerome gambit.
4...Kxf7 5.Nxe5+ Kf6
Four years ago, in "BSG: Later on in the Discussion", I suggested that now, after 6.Nf3, the game would be equal. Shortly afterwards, I faced 5...Kf6 played by RVLY, a specialist in the line (see "Whose Territory Are We Fighting On?"), but after 6.c3 Kxe5 we transposed into more regular 5...Ke6 lines. GOH, a member of the Jerome Gambit Gemeinde playing at FICS, has faced 6.c3 Ne6 and 6.c3 d6. To date, The Database does not include a game with my suggestion 6.c3 Nc2+!?
There are 66 games with this line in The Database, played by the likes of Jerome Gambiteers GOH, HauntedKnight, MyGameUMove, stretto, Wall and yorgos.

Or 7...Nc6 8.d4 d6 9.d5 Bxg4 10.Qxg4 Qd7 11.Qxd7+ Kxd7 12.dxc6+ Kxc6 13.0-0 Nf6 14.f3 h6 15.Be3 Be7 16.Nd2 b5 17.Nb3 a6 18.Nd4+ Kb7 19.Nf5 Bf8 20.Bd4 Re8 21.Rfd1 Re6 22.a4 g6 23.axb5 gxf5 24.bxa6+ Ka8 25.exf5 Re5 26.Bxe5 dxe5 27.Rd8+ Ka7 28.Ra5 Bc5+ 29.Rxc5 Rxd8 30.Rxc7+ Kb8 31.Rc6 Nd5 32.Rxh6 Nf4 33.g3 Rd1+ 34.Kf2 Nd3+ 35.Ke2 Nxb2 36.Rb6+ Black resigned, Wall,B - GYHZ, FICS, 2010.

9.Ne5 Qe8 10.d5
Unsettling the pawn front and ignoring the pawns left behind (e.g. at g2). White should have tried 10.0-0 followed by adding another pawn to the center with f2-f4.
10...Nc5 11.Bg5+ Nf6 12.Qd4 d6 13.Nc4
White might have done better to try 13.Nd2 dxe5 14.Qxc5+ Kd8 15.Qe3, although Black would still have the advantage.
Striking back at the pawns.
14.Bxf6+ gxf6 15.g3 Qxe4+ 16.Qxe4+ Nxe4 17.0-0
The g-pawn is safe, but Black will now unravel his position and make use of his extra material. White does not complicate enough to distract him.
17...Kf7 18.Re1 Ng5 19.Nbd2 Bg4 20.Re3 Bh6 21.f4 Nh3+ 22.Kg2 Rhe8 White resigned
There is still play in the game, even after the Rooks are exchanged, but with only a pawn for Black's piece, it would be all uphill for White.
