Jerome Gambit: Good vs Bad



In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game Black reaches an even, and safe position, but he soon has to deal with a "bad" Bishop vs a "good" Knight, and untangling that situation costs pawns - and the game.

Black has returned the sacrificed material to reach an even game - which, he believes, will even be safer after an exchange of Queens.

15.Qxd6 cxd6 16.Nc3 d5 17.Bg5 Rac8 18.Rf2 h6 19.Bxf6 gxf6 20.Raf1 f5 


White's pawns look healthier, and his Knight has more potential than his opponent's Bishop.

21.Nb5 Ke7 22.Nd4 Kd7 23.Re2 

It would be a mistake to win the f-pawn with 23.Nxf5, as Black would be able to exchange off his stifled Bishop with 23...Bxf5, etc. and then get back the "lost" pawn.

23...Rhe8 24.Re5 Kd6 25.Rfe1 Bd7 


Now the situation has changed, however, and White's Knight can capture, with check. 26...Bxf5 would lose the exchange, but the move that Black chooses surrenders some pawns.

26.Nxf5+ Kc5 27.Ne7 Rcd8 28.Rxd5+ Kb6 29.Rd6+ Kc5 30.Rxh6 Black resigned


Black's Bishop is free - but White's 3 extra pawns give a winning advantage.
