There are a number of recurring tactical ideas in the Jerome Gambit which I like to think of as tools in a toolbox - at hand to help White construct an effective game.
perrypawnpusher - subhann
perrypawnpusher - subhann
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+
The "nudge", a small, but useful tool in the Jerome Gambit toolbox. A good number of opponents take time trying to figure out what the move means. White uses a tempo, but he will get it back against 7...Kf8 or 7...Ke8 if Black later castles-by-hand; while if Black chooses 7...Ke7 or 7...Kf6, his King will be in the way of effective development.
7...Kf8 8.Qxc5+ N8e7
A relatively rare move. See "Wilderness". I have only met this once, in perrypawnpusher - Jaqueperpetuo, blitz, FICS, 2011 (1-0, 25)
9.O-O d6 10.Qe3 Be6
A bit careless, encouraging White to pull out another tool.
11.f4
Of course: the threatened pawn fork.
11...Bd7
Instead, 11...Bf7 was seen in mrjoker - cherryhead/Internet Chess Club, 2008 (1-0, 50).
White can still use the center pawn press.
12.f5 Ne5 13.d4 Nc4 14.Qd3
14...b5 15.b3 Nb6 16.f6
The "Jerome pawn" advances to open up the enemy position. It is not immediately decisive, as White still has to complete his development to follow through on the open lines, but the advantage it provides is clear.
16...gxf6 17.Rxf6+ Kg7 18.Qf3
18...Rf8
This move turns the game over to White. Stockfish 7, after the game, suggested 18...Bf5!? returning the extra piece, although after 19.Bg5 Bg6 20.Re6 Rf8 21.Bf6+ Kg8 22.Rxe7 Qxe7 23.Bxe7 Rxf3
24.gxf3 White would have a two pawn advantage.
19.Bh6+
One last tool - the Bishop check from h6.
19...Kh8 20.Rxf8+ Ng8 21.Rxd8 Rxd8 Black resigned
White wins the exchange after 22.Qf7 Nxh6 23.Qf6 Kg8 Qxd8+ with an overwhelming material lead
