More Than Meets the Eye

One of the joys of chess, and this has to be true even for that reprobate of openings, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and its relatives, is that often things on the board are not as they first appear to be: there is more than meets the eye.

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


This is a solid response for Black – computers will rate the second player about 1 1/4 pawns better.

Familiarity has its benefits, however: my score with White against this position in 36 games is 93%.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3


9...Be6

This move is not as bad as I thought it to be, and my response is not as good as I thought, either.

10.f4

Black's response should cure me of this premature move.

I was more on target in an earlier game with 10.0-0 Nf6 11.f4 Kd7 12.f5 Bxf5 13.exf5 Re8 14.Qg5 Ne7 15.Qxg7 c6 16.Qxf6 Black resigned, perrypawnpusher - dirceu, blitz FICS, 2010

10...Qh4+


Thematic, and an improvement over 10...N6e7 11.0-0 Nc6 (11...Nf6 12.f5 Bf7 13.d3 c6 14.h3 Qb6 15.g4 Qxe3+ 16.Bxe3 Kd7 17.Nd2 b6 18.Kg2 g6 19.g5 Nh5 20.f6 Nc8 21.d4 b5 22.b3 Nb6 23.Rac1 a5 24.c4 bxc4 25.Nxc4 Rhb8 26.Kf3 Nxc4 27.bxc4 Rb2 28.Rf2 Rab8 29.d5 c5 30.Rcc2 Rxc2 31.Rxc2 a4 32.Rc3 Kc7 33.Ra3 Be8 34.e5 dxe5 35.Bxc5 Rb2 36.Ke4 Re2+ 37.Be3 Bd7 38.f7 1-0, mrjoker - Melbourne, ICC 2 12 blitz, 2008,) 12.d4 Bf7 13.Nc3 Qd7 14.e5 dxe5 15.dxe5 Qe6 16.f5 Qxe5 17.Qxe5+ Nxe5 18.Re1 Rd8 19.Bf4 Kd7 20.Bxe5 Nf6 21.Bxf6 gxf6 22.Ne4 Kc8 23.Nxf6 Rd6 24.Ne4 Rdd8 25.Rad1 Rxd1 26.Rxd1 Re8 27.Nc3 Bc4 28.Kf2 Rf8 29.g4 c6 30.b3 Bf7 31.Ne4 Bd5 32.Nc5 Rf6 33.c4 Black forfeited on time, perrypawnpusher - GabrielChime, blitz FICS, 2010

11.g3 Qg4


Here Black's followup is inaccurate, however. Certainly the Queen can be more annoying at h3.

After 11...Qh3, White might as well continue developing with 12.Nc3, as the pawn fork 12.f5, instead, would win a piece after 12...Bxf5 13.exf5+  but allow after 13...Kf8 the deadly move ...Rae8.  

12.f5

Now the pawn fork works, however.

12...Bf7

A bit better, but still leading to an edge for White, was 12...Nf6, which is best answered by 13.d3.

The problem now with 12...Bxf5 for Black is that after 13.exf5+ Kd7 (threatening ...Rae8, as in the not to White's 12th move) White can safely castle out of the threatened pin of his Queen. 

With a Black Queen on h3, that would not have been possible.

13.fxg6 Bxg6 14.d3 Kd7 15.0-0 Nf6 16.Nc3 c6


White is a pawn up.

17.Qf4

An exchange of Queens would make my King safer: Black has 4 pieces on the Kingside (with another Rook waiting in the wings) to my 2 pieces.

17...Qe6 18.Bd2 Rhf8 19.Qg5 Rf7 20.Rae1 Raf8


21.e5 dxe5 22.Qxe5


22...Qh3

Black declines to exchange Queens (his best choice), seeing his chances for an attack on the enemy King (starting with pressure on f1) to be good.

23.Bf4


It is Black's King, on the Queenside, however, who is at greater risk. 

23...Ne8

Not so good, but Rybka's suggestion after the game – to exchange Queens and give up a piece – is not attractive, either: 23...Qxh2+ 24.Kxh2 Ng4+ 25.Kg2 Nxe5 26.Rxe5.

24.Qd4+ Kc8 25.Qxa7


26...Nd6 26.Qa8+

Noticing that capturing Black's Knight now leads to me being checkmated, I was a bit too nervous to work out the cool Knight sacrifice at b5, but after the game Rybka did: 26.Nb5 cxb5 (26...Nxb5 27.Qb8+ Kd7 28.Qxb7+ Kd8 29.Bg5+ Rf6 30.Qxg7) 27.Qc5+ Kd8 28.Qxd6+.

26...Kd7 27.Qa3


27...Nc8

White's Bishop is making things too hot, and Black needed instead to sacrifice the exchange with 27...Rxf4 in order to stay in the game.


28.Qc5 b6


Swatting at my Queen as if she were a bothersome mosquito, Black hastens his end.

29.Qd4+ Black resigned


Checkmate is unavoidable.
