Jerome Gambit: In the End, A Win

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is a hard-fought battle, as both players work to make something out of a relatively balanced position. At first, White makes progress, but the clock seems to undo that. Then, Black's chances slip by. Finally, in a drawn position, the defender makes one last play - and then must surrender the full point.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+ 


Along with several Readers, I have begun to think of this line as a "double Jerome Gambit". It is often used as a psychological counter gambit by Black, with a return of material leading to a forced exchange of Queens, blunting White's attack.

In this game, however, Black prefers to keep the Queens on the board, so perhaps his move choice was based on "You sacrificed a Bishop to keep me from castling, so I will do the same to you".

9.Rf1 d6 10.Qd4 c5 11.Qc3 Kg7 12.Kg1 Rf8 

The position is not an exciting one, but White has an extra pawn to work with.

13.d3 b5 14.Bg5 b4 15.Qd2 Nxe4 


A tactical slip.

16.Bxd8 Nxd2 17.Rxf8 Kxf8 18.Nxd2 Bf5 19.Bc7 d5 20.Bd6+ Kf7 21.Bxc5 Rc8 22.Nb3 Ke6 23.Re1+ Kf6 

White is a piece and a pawn ahead. He just has to find a plan to make it all work.

24.h3 Kg5 25.g4 Bd7 26.Re5+ Kh4 27.Re7 Bc6  28.Rxh7+ Kg3 29.Bd6+ Kf3 30.Nd4+ 

Missing 30.Re7, and then 31.Nd4#.

30...Ke3 31.Nxc6 Rxc6 32.Bxb4 Rxc2

Black now manages a bit of counter play, but it is nothing that White can not handle.

33.Rxa7 Rxb2 34.Bc5+ Kxd3 35.Rd7 Ke4 36.Bf8 Rxa2 37.Rg7 Ra1+ 38.Kf2 d4 

39.Rxg6 d3 40.Rd6 Ra2+ 41.Ke1 Ra1+ 42.Kd2 Ra2+ 43.Ke1 Rh2 


Black adds threatening the enemy pawns to his plan to advance his passed pawn. White's Bishop should help hold things together, however.

44.Rh6 Kf3 45.g5 d2+ 46.Kd1 Ke3 47.Bc5+ Kd3 48.Rd6+ Kc3 49.Rxd2  

This looks like a time error. Instead, 49.Bd4+ Kb4 50.g6 Rxh3 51.g7 Rg3 52.Kxd2 is how to use his advantages and advance to the win.

49...Rxd2+ 50.Kc1 Rg2 51.Be7 Kd4 


Black pursues the draw, instead of the win with 51...Rg1#. This has got to be due to a shortage of time.

52.h4 Ke5 53.h5 Ke6 54.Bf6 Kf7 55.h6 Kg6 56.Kd1 Ra2 57.Kc1 Rh2 58.Kd1 Rh3 59.Ke2 Rh5 60.Kf3 Rh4 61.Kg3 Ra4 62.Kf3 Kh7 


Black has effectively blockaded the pawns and kept the enemy King at bay. A draw would be an honorable result.

63.Ke3 Rc4 64.Kd3 Rh4 65.Ke3 Rg4 66.Kf3 Ra4 67.Ke3 Ra6 68.Kf4 Rxf6+ 

A miscalculation. White's King is one step too close to the pawns.

69.gxf6 Kg6 70.Ke5 Kxh6 71.Ke6 Kg6 72.Ke7 Kh7 73.f7 Black resigned
