Compared to the urban superhighways of the Ruy Lopez or King's Indian Defense, the Jerome Gambit is a path through the woods. Some lesser-played lines are a trudge through the wilderness. In the following game, White, with 155 games in The Database, travels, then wanders, then gets a bit lost - fortunately for him, his opponent is even less prepared for the journey.

11.f4 Rf8 12.f5 Ne5 13.Qb3+ d5
White is working to interfere with Black castling-by-hand. He should take a moment, now, to support his center with 14.Nc3. Instead, he continues to go after the enemy King.
14.f6 gxf6 15.exd5 Qxd5 16.Qg3
White does not want to exchange Queens and weaken his chances for an attack, but this move puts Her Majesty in a risky position and strengthens Black's counter-attack.
Even stronger is 16...Rg8.
17.d3 Bg6 18.Nc3 Qe6 19.Bh6 Rg8 20.Rae1
In this complicated position Stockfish 6 recommends the bizarre 20...Be4!? 21.Bg5 Bf5!? when White's Bishop, not Black's, will be in danger, finishing up with 22.h4 h6 23.d4 Qb6 24.Qf2 hxg5 25.dxe5 Qxf2+ 26.Rxf2 gxh4 27.exf6 Kxf6 28.Rxf7 Kxf7 29.Rxf5; Black is ahead the exchange.
However, the defender gets lost in the woods.
20...Qd6 21.Rxe5 Black resigned
This is a complicated position (exchanging Queens first with 21.Qxe5 Qxe5 22.Rxe5 might have helped White) and it is difficult to see Black resigning while just a pawn down, but perhaps he had his fill of the wilderness or his clock was winding down.
