Complicated


In the third round of the Chess.com Italian Game Thematic tournament I was only able to play one Jerome Gambit. It turned out to be a complicated affair, but I was able to bring home the point.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+



The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 



My opponent was not going to let me use anything that I had learned from watching Philidor1792 explore the 7...Bd6 line.

8.Qxd4 d6 9.Bg5 h6 

An earlier game of mine had continued 9...Nc6 10.Qd3 Re8 11.0-0 Kg8, perrypawnpusher - Philidork, blitz, FICS,2010 (1-0,17).

I planned to castle Queenside this time, an idea that I got from  Wall, Bill - Stayshot, Chess.com, 2010, which somehow has not made its way onto this blog until now (although it is in The Database): 9...Rf8 10.0-0-0 c6 11.f4 Ng6 12.e5 h6 13.exf6 hxg5 14.fxg5 gxf6 15.Ne4 fxg5 16.Rhf1+ Kg8 17.Nf6+ Kh8 18.Ne8+ Kg8 19.Qg7 checkmate

It turns out that Alonzo Wheeler Jerome played 0-0-0 in various Jerome Gambit lines, the first being Jerome - Brownson, Iowa, 1875 (1-0, 43). It does not look like that game has made it to this blog, either: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 Nf6 11.d3 Ke7 12.Nc3 d6 13.Bf4 Qe6 14.0-0-0 Qg4 15.Qf1 g5 16.Bg3 Be3+ 17.Kb1 Bf4 18.Bf2 c5 19.h3 Qh5 20.h4 Be6 21.hxg5 Qxg5 22.Bh4 Qg4 23.Nd5+ Bxd5 24.exd5 Rae8 25.d4 Bg5 26.Bxg5 Qxg5 27.dxc5 dxc5 28.Qb5 b6 29.d6+ Kf7 30.Rhf1 Kg7 31.Qc6 Rhf8 32.a3 Rd8 33.g4 Nxg4 34.Qc7+ Kg8 35.Rxf8+ Rxf8 36.Qxa7 Qd8 37.Qa4 Ne5 38.Qe4 Ng6 39.Qe6+ Rf7 40.d7 Nf8 41.Qe8 Qxd7 42.Rxd7 Rxd7 43.Qb8 Black resigned

10.Bh4 Be6 11.O-O-O Qe7 12.f4 Nc6 13.Qe3 Qf8 



Black takes his Queen off of the d8-h4 diagonal, while keeping it on the a3-f8 diagonal. It is not a bad move, but it got me thinking that it was time to advance in the center.

White has three choices: f4-f5; Bxf6 followed by f4-f5; or e4-e5.

14.e5 Ng4

I expected this Knight challenge, as neither my opponent nor I thought that 14...dxe5 was playable. It turns out that Black can respond either 15.Qb4 or 15.Ng4 with a slight edge.

Still, I had prepared a surprise for my opponent.

15.Qe4 dxe5 

Perhaps expecting 16.fxe5, which is well-met by 16...Qb4, when White will simply be worse after the exchange of Queens, or will not have enough of an attack after 17.Rf1+ Kg8.

16.f5

Now, two of Black's pieces are hanging, and White will be better.

Black resigned, which may have been in response to his surprise, or frustration with his failed plan. 

Yet, after the necessary 16...Kg8, and the reasonable 17.fxe6, he could have tried 17...Qf4+, 18.Kb1 Qxe4 19.Nxe4 Re8 as White's advanced passed pawn on e6 will not prove very strong. In fact, it might be best for White to trade it off directly with 20.Rc7 Rxe6 21.Rxc7, when Black will have his own passed pawn on e5, even if he subsequently loses another pawn (say, the one at b7). White might have an edge, but not a large one...

Not As Scary As It Looks

Have you ever played what you thought was a smashing attack – only to discover, upon closer inspection, that it wasn't nearly as sound as you (and your opponent) imagined? If you play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) – of course you have.

perrypawnpusher  - Philidork
blitz FICS, 2010

1.e4 e5 2.Nf3 Nf6 3.Nc3 Nc6 4.Bc4 Bc5


5.Bxf7+

The Italian Four Knights Jerome Gambit, one of those lines known to me personally as the Why-Am-I-Still-Playing-This Opening??

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4


This seems to be the most popular defense, although 7...Bd6 8.dxe5 Bxe5 was stronger.

8...d6 9.Bg5


Or the alternative: 9.0-0 Re8 10.f4 (10.Bg5 Kg8 11.f4 Nc6 12.Qd3 Nb4 13.Qc4+ Be6 14.Qxb4 b6 15.Rae1 c5 16.Qb5 d5 17.e5 d4 18.exf6 a6 19.Qc6 Bd7 20.Qd5+ Kh8 21.fxg7+ Kxg7 22.Bxd8 Black resigned, Wall - Foman, Chess.com, 2010) 10...Nc6 11.Qd3 Kg8 12.Bd2 a6 13.Rae1 Kh8 14.Nd5 Nxd5 15.exd5 Rxe1 16.Rxe1 Na7 17.Qe4 Bg4 18.h3 Bh5 19.g4 Bf7 20.Bc3 Qe8 21.Qf5 Qf8 22.Qd7 Nb5 23.Re7 Nxc3 24.Rxf7 Qe8 25.Qxe8+ Rxe8 26.bxc3 Kg8 27.Rxc7 b5 28.Kf2 Re4 29.f5 Ra4 30.Rd7 Rxa2 31.Rxd6 Rxc2+ 32.Ke3 Rxc3+ 33.Kd4 Rc4+ 34.Kd3 Rc5 35.Rxa6 Rxd5+ 36.Ke3 Rd1 37.Rb6 Rb1 38.Kd4 Kf7 39.g5 Kg8 40.g6 Rd1+ 41.Ke5 Re1+ 42.Kf4 Re8 43.Rxb5 hxg6 44.fxg6 Rf8+ 45.Rf5 Rxf5+ 46.Kxf5 Kf8 47.Ke6 Kg8 48.Ke7 Kh8 49.h4 Kg8 50.h5 Kh8 51.Ke6 Kg8 52.Kf5 Kh8 53.Kg5 Kg8 54.Kf5 Kh8 55.Ke5 Kg8 56.Ke6 Kh8 57.Kd7 Kg8 58.Ke7 Kh8 59.h6 Kg8 60.h7+ Kh8 61.Kf8 Game drawn by stalemate, perrypawnpusher - KaZC, blitz FICS, 2010.

This position is of historical interest, as it appeared in two games in a Jerome Gambit correspondence chess match between Alonzo Wheeler Jerome and S.A. Charles, presented in an article by Charles in Brentano's Chess Monthly, October 1881.

The move order in those games was 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.Nc3 Nf6 9.Bg5.

9...Nc6

Or 9...h6 10.Bxf6 Qxf6 11.0-0-0 Be6 12.Kb1 Nc4

"so far from an unfinished game between Mr. Jerome and the writer, the following seems a possible continuation 13.Qd3 b5 14.f4 Nxb2 15.Kxb2 b4 and wins." Jerome - Charles, correspondence, 1881;






analysis diagram





Also possible was 9...Bh3 10.0-0-0 Bxg2 11.f4 h6 12.Bxf6 gxf6 13.Rhg1 Bh3 14.fxe5 "better game [for White]. from a game between Mr. Jerome and the writer"

10.Qd3


10...Re8 11.0-0 Kg8


12.Nd5 Re6 13.Nxf6+


Part of a "plan of attack," but 13.f4 followed by 14.e5 was more sensible.

13...gxf6 14.Bh6


14...Ne5

After I played my 14th move, I suddenly wondered, what if Black plays 14...f5...? The answer is, of course, that White's "attack" crumbles.

The move played by Philidork shows that he sees my plan to check along the g-file, and he hastens to cover up.

15.Qg3+ Ng6


Now White can achieve an even game with the straight-forward 16.f4 Rxe4 17.f5.

16.h4 Kh8


White "attacks" with the h-pawn, which can be stopped by the simple 16...Re5.

17.h5

Unfortunately, my opponent was taken in by all of this and resigned here.

True, if the Knight moves, White can checkmate at g7. But Black is a piece ahead, so he can afford to defend with 17...Qg8 – when all I would have after 18.hxg6 Qxg6 was an even game.

Looking back, the situation was not as scary as it looked.
