In Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games, it seems that victory for the attacker turns on a few things happening, while defeat turns on a few things not happening. In a 5-minute game, sometimes that works out, and sometimes it doesn't. But - the games are always exciting. ratconspiracy - titulajebordo 5 0 blitz, Chess.com, 2020 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
The Knight's attack on the Queen should serve no purpose. For example, if now 13.Qd3 Qh4 14.h3 and it will have to move. 13.Qg5 Qxg5 14.Bxg5 h6 15.Be3 Nxe3 16.fxe3 Ne7
White has 2 pawns for his sacrificed piece, but they are not mobile. The exchange of Queens has taken the life out of his attack, as well. It will take some pluck and some luck to make progress. 17.Nd5 Nxd5 18.exd5 Bg4 19.e4 Rf8 20.e5 Rxf1+ 21.Rxf1 Ke7 22.e6 Rf8
The protected, passed pawn is something of value, but for now it is effectively blockaded. If there were an attack on the tied-down King, White might be able to make something of the position. In the meantime, too many pawns are stuck on the same colored squares as the Bishop. 23.c4 Rxf1+ 24.Kxf1 Bf5 25.c5 Be4 26.c6 bxc6 27.dxc6 Bxc6 28.Ke2 Kxe6 29.Kd3 Bxg2 30.Kc4 c6
Black is clearly better. But, is time on his side? 31.b4 Bd5+ 32.Kc3 g5 33.a4 h5 34.b5 axb5 35.axb5 cxb5 36.Kb4 Bc4

I have received a number of Jerome Gambits that show clearly why players are drawn to it - the sacrifice shows up in a variety of lines, and the games feature quick finishes. Take a look. In his first Jerome, Kylon tries what I have begun to call an "impatient Jerome Gambit" (White doesn't wait for ...Bc5) against the Hungarian Defense. In this case, impatience is rewarded, with a checkmate in 9 moves.
