The Fog of War (Part 2)

It's a strange thing, but playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can have unusual effects upon those who play it or who play against it. The following game is as another example...

perrypawnpusher - Lark

blitz 2 12, FICS, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 The same foggy location as yesterday's post (see "The Fog of War (Part 1)"

7.Qxe5 Bd6 8.Qc3

Alternately: 8.Qh5 Nf6 9.Qf3 Kg8 10.d4 Kf7 11.e5 Black resigned, blackburne - Whiterose, ChessWorld, 2004.

White's Queen seems to be in the way at c3.

8...Nf6 9.d3 Qe7 10.Bg5
A truly impressive oversight!

10...h6


Anyone for "10...Bb4, White resigned", instead?

11.Bh4

Amazing. I have no idea what I was looking at, or what I was seeing.

11... Bc5
That goes for my opponent, too.

12.0-0 d6

Now we're back to a "normal" Jerome Gambit, where Black has his regular advantage of a piece for two pawns. That doesn't mean that the fog has fully cleared up, though.

13.d4 g5 14.dxc5 gxh4 15.cxd6 Qxd6Recapturing with the pawn was correct. Now White has the simple pawn fork, 16.e5.

16.Nd2

Or not.

16...Rg8 17.f4 Bh3 18.Qxh3 Qxd2 19.Rf2 Qd4

White hopes to feast on Black's Kingside pawns, and that he can keep active enough to keep his opponent from doing the same on the Queenside.

20.Qf5 Qxb2 21.Re1 Qb6 22.e5


Getting the piece back and evening up the game.

22...Rg7 23.exf6 Rf7 24.Re6 Qb1+ 25.Rf1 Qxa2 26.Rfe1

Lark has gobbled two pawns, but I clearly have the initiative and the advantage.

26...Qb2 27.Qg6

Missing 27.Re8+ Rxe8 28.Rxe8+ Kxe8 29.Qc8 checkmate

27...Qd4+ 28.Kh1 Qxf4 29.Re7

Missing the much stronger 29.Qd3, but this was a blitz game, and time was running short...

29...Rxe7 30.fxe7 checkmate


...for both of us.

The Fog of War (Part 1)

It's a strange thing, but playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can have unusual effects upon those who play it or who play against it. The following game is as good an example as any...


DREWBEAR 63 - Crusader Rabbit
JGTourney4 ChessWorld, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8

A solid defense as old as 1874, when Alonzo Wheeler Jerome suggested it.

7.Qxe5 Bxf2+ An unusual, likely premature, return of material, as in perrypawnpusher - Lindal, FICS 2007.

8.Ke2

Surprising. Perhaps he did not want to play the pawn-up Queenless-middlegame after 8.Kxf2 Qf6+.

8...Qf6

Equally surprising, considering that the Bishop, having done its damage, could retire with 8...Bb6.

9.Qxc7

There was not a lot of excitment in 9.Qxf6+ Nxf6 10.Kxf2 Nxe4+, but it was probably best.

9...Qa6+ 10.d3

10...Bb6

Finally.

11.Rf1+ Nf6 12.Qf4

That's okay: White hopes to win the Knight, anyhow.

12...Bd4 13.c3 Be5

Aha! It is the Bishop, after all!

14.Qxe5 Qe6 15.Qc5+

See what I mean about the impact of the Jerome Gambit. Mind you, each player had several days to consider each move. More helpful would have been 15.Qxe6 dxe6 16.e5, when White has nabbed both the Bishop and Knight.

15...d6 16.Qc7 Bd7 17.h3 Ke7 18.Bg5 Rhf8

19.Nd2 Kf7 20.Nc4 Kg8

21.Nxd6 Nxe4

Oversight or miscalculation? Black's game begins to shudder.

22.dxe4 Rxf1 23.Rxf1 Rf8 24.Rxf8+ Kxf8 25.Qd8+ Be8 26.Nxe8 Qxe8 27.Be7+ Kf7 28.Qxe8+ Kxe8

The exchanges have left White with a won endgame.

29.Ba3 a6 30.b4 Kd7 31.c4 Ke6 32.Kd3 g6 33.Bc1 Kf7 34.a4 Ke6 35.Kd4 b6 36.c5 b5 37.axb5 axb5 38.e5 h5 39.Bh6 Kd7 40.Kd5 Kc7 41.e6 Kd8 42.Kc6 Ke7 43.Kxb5 Black resigned

Oooooooops... 2

As I've said before: Playing – or defending against – the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) requires close attention to what is going on, so that every tactical opportunity can be caught. Take advantage of your chances, you could take the point. Overlook a chance or two, and ooooooops...

The Modern Jerome Gambit

I have been using the games of the current Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament at Chessworld to gain a better understanding of the "modern" (non-5.Nxe5) variations, especially since they make up about 80% of the games there.

Here is a sampling of recent trials.

* Poof! *

Remember the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament that I mentioned a few posts ago (see "Busy!") – the one that I had joined, a 10-player double-round robin?

Turns out almost nobody was interested in playing the Jerome Gambit – only 3 games out of 81 went that way. My hat off to leif41no and Namecheck for playing a couple of Jerome-ish games with each other (actually, the games started 1.e4 e5 2.Nf3 Nf6 3.Bc4 Bc5 4.Bxf7+). I will let you know how they do.

In the meantime, I have one Jerome against jamtaylo. Since I don't plan on contesting the non-Jerome Gambit games, and will lose them by forfeit, that raises an interesting question: am I being unfair to jamtaylo?

Yes, Sir!

Here are three more games from the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament at Chessworld – this time, three wins by a Jerome Gambit veteran, Sir Osis of the Liver.

The Opponent

Whether it was Tarrasch, Tartakower or Znosko-Borovsky who said "Before the endgame, the gods have placed the middlegame," it seems equally important to note here that "Between the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and a victory, stands the Opponent."

perrypawnpusher - spontex

blitz 8 8, FICS, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.f4 g6 A new move, but not such a good one, as it returns too much material. Standard is 8...Qf6 or 8...Qh4+.

9.Qxe5+ Kc6 10.Qd5+

Going for the non-existent mate. It was better to take the Rook, although play remains complicated, if in White's favor, after 10.Qxh8 Qe7 11.Nc3 Nf6 12.e5.

10...Kb6 11.Nc3 c6

This move helps White get back on track. After the game Rybka 3 suggested: 11...a5 12.Na4+ Ka7 13.Qxc5+ b6 14.Qd4 Ne7.

12.Na4+ Kc7 13.Qe5+ Bd6 14.Qxh8 Qh4+ 15.g3 Qg4

A very interesting offer of even more material, with the opportunity to muddy things up. A reasonable response for White now is 16.d3.

16.Qxg8 Qf3 17.Rf1 Qxe4+ 18.Kd1 b5

Too generous: 18...Qxa4 was the right move, leaving White up the exchange and a pawn.

19.Nc3 Qd4

More mischief was available with: 19...Qg2 20.Re1 Qxh2 21.d4 Qxg3 22.Qxh7 Ba6.

The annoying thing was that I was a Rook ahead, and it didn't feel at all like I was winning.

20.Qxh7 Bb4 21.Qxg6 d6 22.Qd3

To put an end to Black's dangerous piece play, although 22.Ne4 was clearly stronger.

22...Bg4+ 23.Ne2 Qxd3 24.cxd3 Re8 25.Re1 c5

26.a3 Ba5 27.b4 cxb4 28.axb4 Bb6 29.Bb2 Bf2

My opponent refused to roll over and play dead. Still, 30.Kc2 would limit my damages now.

30.d4 Bxe1 31.Kxe1 Rxe2+ 32.Kf1 Rxd2 33.Bc3 Rxh2 34.Rxa7+ Kb6

Well, okay, White still has an advantage. A small one.

35.Rf7 Bh3+ 36.Kg1 Rg2+ 37.Kh1 Rxg3 38.Rf6

How to explain this move?? Would you believe that my dog, Ginger, was pestering me to go outside, so I made a move quickly – and then watched my Bishop disappear.
38...Rxc3 39.Rxd6+ Kc7 40.Rd5 Kc6 41.Rh5 Bg4 42.Rg5 Bf3+ 43.Kh2 Bd5 44.f5



And here we have what might be guessed to be a "typical" Jerome Gambit endgame, where White has two pawns against Black's piece. The one problem: White's game is lost.


44...Rc4 45.Rg6+ Kc7 46.Rg7+ Kd6 47.Rg6+ Kd7 48.Rg7+ Kd6 49.Rg6+ Ke7 50.Rb6 Rxb4 51.Kg3 Rxd4


An unfortunate slip, levelling the game: 51...Kd7 52.Kf4 Kc7 was much better.

52.Rxb5 Kf6 53.Kf2 Kxf5 54.Ke3 Re4+ 55.Kd3 Re5 56.Kd4 Re4+ 57.Kxd5 Re5+ 58.Kc4 Rxb5 59.Kxb5 Drawn
Hats off and a firm handshake to spontex, for a fight to the finish.
