Jerome Gambit: Who'd A Thunk It?

I just received another Jerome Gambit game played on the internet by Vlasta Fejfar ("vlastous"). The following game show the need for patience in certain lines of that wild, crazy attack. A certain amount of sitzfleisch helps, too. After a period of calm, White suddenly activates his Rooks, and Black does not react well to the danger.

[By the way, this is post #2,500 on this blog. As Mortimer Snerd - or Edgar Bergen - said, "Who'd a thunk it?"]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 8.Qf4+ Qf6

The defense 6...Kf8 is solid and sensible. It can lead to a position where the Queens come off the board before a dozen moves have been played. "Objectively" Black's extra piece is worth more than White's two extra pawns, but in the rough-and-tumble of club play - especially when the first player has knowledge or experience of such lines - there is play to be had for the gambiteer.

9.d3 Qxf4 10.Bxf4 Nf6 11.Nc3 

White has his two "Jerome pawns". Black's extra piece gives him the "two bishops" which are helpful in open positions.

From a psychological point of view, White should consider keeping the game closed, developing his pieces, increasing his control of space - but, otherwise, acting as if Black is the attacker, and letting him make the first mistake.

13.Bg3 Re8 14.Bf2 Bb4 15.a3 Bxc3+ 16.bxc3 b6

Black has surrendered the Bishop pair to injure White's pawn structure. He still has a long way to go to collect more than a half point, however. In the meantime, White startssome action on the Kingside.

17.Kd2 Bd7 18.g4 h6 19.h4 d5 20.g5 hxg5 21.hxg5 Ng8 

White is ready for some action on the Kingside, starting with a surprise.

22.g6+ Kxg6

Immediately, Black slips. He would have done better side-stepping the pawn with 22...Ke6, but he misses White's plan (perhaps because White has been so "quiet" with his play. The capture allows White a useful gain of tempo in response.

23.Rag1+ Kf7 24.Rh7 Ke7 

You can see the rest of the game from here. Whites Rooks spring to life.

25.Rgxg7+ Kd6 26.Rxd7+ Kc6 27.Rxc7+ Kb5 28.exd5 Nf6 

Black is suddenly 4 pawns down, 3 of them passed, but he hopes to use this Knight fork to win one back. Alas he slips.
