Jerome Gambit: Theory and Practice (Part 4)

In the following game, White confidently and patiently makes his way through the opening and middlegame, indifferent to his opponent's attempts to simplify - and, later, to look for dynamic chances. The endgame win is there; he just has to keep strolling until he gets there.

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6 

8.Rf1 g6 9.Qh3+ Ke7 10.fxe5 Qxe5 11.Qf3 Nf6 12.Nc3 c6 

White's play was inexact after 12...Bd4 in Gary_Seven - Kevin the fruitbat, JG3 thematic, ChessWorld.net, 2008:  13.d3 Bxc3+ 14. Bd2 Bxb2 15. Rb1 Bc3 16. Bxc3 Qxc3+ 17. Kd1 d6 18. h3 Bd7 19. g4 Rhf8 20. d4 Qxf3+ 21. Rxf3 Nxe4 22. Rxf8 Rxf8 23. Rxb7 Bb5 24. Rxc7+ Kd8 25. Rxa7 Rf1 checkmate.

What happens next in the text is that Queens are exchanged and the sacrificed piece is returned for a couple of pawns, giving Black a small advantage. The game is not over at all, however.

13.Ne2 Rf8 14.d4 Bxd4 15.Bf4 Qxe4 16.Qxe4+ Nxe4 17.Nxd4 d5 

18.O-O-O Bg4 19.Rde1 Kd7 20.h3 Bf5 21.Bh6 Rf7 22.Nf3 Re8 23.g4 b6 

An odd choice by Black. He will have two pawns for his piece, a typical Jerome Gambit situation for White. Perhaps it was a slip, perhaps he saw that situation as more dynamic that a possible Bishops-of-opposite-colors endgame.

Black's extra pawns are more targets than attacking units, as White begins to show.
