Jerome Gambit: One Minute Ninja

White's play in the following game reminds me of a ninja attack. He quickly gains the better position, then takes advantage of his opponent's mistake, delivering checkmate. All with only a minute to play.

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.

9...Nc6 10.Qd3 Bd7 11.e5 dxe5 12.fxe5 Nxe5 13.Qd5+ Be6 14.Qxe5 Qd6 

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. 

Jerome Gambit: A Plan

When facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it is always usefule to have a plan. It is also helpful if the plan has been tested and shown to be safe. In the following gambit, this is not the case.

Jerome Gambit: Tripping Over Each Other

In the following game, Black develops his pieces quickly. However, they seem to be a bit jumbled, tripping over each other - and, soon, the Queen is lost. Not too long after, the King is lost as well.

Jerome Gambit: Roller Skating on Ice

The following game brings to mind the notion of roller skating on ice - the defender never seems to get his balance, and a fall is always expected. It is useful to play over the game, move-by-move, and ask yourself what White should do, next - someday you may have such an opportunity, and it is good to be ready.

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d5 

The move ...d7-d5 is often helpful in double e-pawn openings, and that includes the Jerome Gambit, but here the defender has overlooked the fact that his Knight is en prise. Better 7...d6.

8.Qxe5 Qd7 

Creative. Safer was 8...Nf6. 

9.Qh5+ Kf8 10.Bg5 

Komodo 10 recommends 10.Qxd5, but there has to be more to the position, from a human point of view, than entering a Queenless middlegame after 10...Qxd5 11.exd5.

10...Nh6 

No doubt avoiding White's intended 10...Nf6 11.Bxf6, but the time for psychology was well passed.

11.Bxh6 gxh6 12.Qxh6+ Ke8 

13.Nc3 Rg8 

To support the Queen when she comes to g7 to make the exchange...

14.Nxd5 Qg7 15.Nf6+ Black resigned

Disrupted to the end: Black can move his King and protect his Rook, only to realize that after 15...Kf7 16.Nxg8 White has protected his own Queen, and 16...Kxg8 17.Qxg7+ Kxg7 is not survivable, unless White's clock is ready to flag. 

Jerome Gambit: Classical vs Hypermodern

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a fascinating battle between classical attack - featuring pawns in the center - and hypermodern defense - utilizing pieces that are often willing to retreat, yield ground, and then return to apply pressure.
