Jerome Gambit: You Checkmate Your Way, I'll Checkmate Mine

In the following Jerome Gambit (1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.Bxf7+) game, White reaches a point where he has an overwhelming advantage. He figures out a win by checkmate, and pursues it, bypassing faster mates - in a blitz game, this is not unusual, and a win is what is necessary, not necessarily the fastest win.

1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.Bxf7+ 

4... Kxf7 5.Nxe5+ Kf8 

This move is at least as old as Jerome - Brownson, Iowa, 1875 (1/2 - 1/2, 29). Some history.

6.Nxc6 

The most straight-forward continuation, although it is also possible for White to simply castle - a move that usually occurs in main line Jerome Gambit play - and look for transpositions.

6...dxc6 7.Nc3 Nf6 8.d3 Bg4 9.f3 Be6 

Here we have the classic Jerome Gambit imbalance: Black has an extra piece, White has 2 extra pawns. 

Black's capture 6...dxc6 was designed to slow down White's possible d2-d4, but, as the game develops, the move becomes possible. Also, the capture turns White's e-pawn into a protected passer, which may be telling, much later in the game.  

10.Ne2 Kf7 11.d4 Bb4+ 12.c3 Ba5 13.b4 Bb6 

It is still a battle of pieces vs pawns, and Black's 2 Bishops look valuable, but the defender is lacking the usual counter-stroke, ...d7-d5.

14.O-O Bc4 15.Rf2 h5 16.e5 Ne4 

A strange oversight - in a 3 0 blitz game, however.

17.fxe4+ Ke6 18.Nf4+ Kd7 19.Ng6 Qe8 

Choosing to give up the exchange, rather than play the stultified 19...Rh7.

20.Nxh8 Qxh8 

Hoping to build a Kingside attack, anyhow.

21.Bg5 Rf8 22.Rxf8 Qxf8 23.Qxh5 Bd3 

Things are getting a litte sloppy, perhaps an indication of the impact of the clock, this being a 3 0 game.

24.Qg6 

Strong enough, although sharp-eyed Readers may have spotted 24.Qg4+ leading to 24...Qf5 (ouch) 25.Qxf5+ Ke8 26.e6 Bxd4+ (what else?) 27.cxd4 Bc4 28.Qf7 checkmate.

24...a5 25.b5 

Okay, but there was also the march of the terrible "Jerome pawn": 25.e6+ Kc8 26.e7. 

25...cxb5 26.Rd1 Bc2 27.Rd2 Ba4 28.Rf2 c5 

A slip, but he was already facing a forced checkmate, so trying to clear the a7-g1 diagonal for his Bishop was as good as anything.

29.Rxf8 cxd4 30.Qxg7+ 

White has figured out his winning line, and that is enough. Readers, without the clock ticking, may want to find some alternatives.

30...Kc6 31.Rf6+ Kc5 32.Qxb7 dxc3 33.Qxb6+ Kb4 34.Qd4+ Ka3 35.Rf3 Kxa2 36.Qxc3 b4 37.Qd2+ Kb1 38.Rf1+ Bd1 39.Rxd1 checkmate

Jerome Gambit: Dangers Along The e-File

Danger!

When facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it can be relatively easy to wander into trouble, especially if you underestimate the attacker's chances in that "refuted" opening. In the following blitz game, Black's chances collapse when he overlooks the dangers to his King along the e-file.

White's centralized Queen cannot be chased away by Black's Queen's Knight, as it resides on g6. Kicking the Queen with ...c5 is possible, but it will leave Black's d-pawn backward.

This capture is a mistake, but Black's next move compounds his troubles. He should have acknowledged the error with 10...Kd8, surrendering the Knight, hoping to play on, a pawn down.

11.Re1 Qh4

This move only works if White now captures with his Queen, as the subsequent exchange of Queens would limit White's advantage. However...

Jerome Gambit: How's That For A Kick In The Head?

It is quite possible that playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7) at slower time controls allows you to absorb enough knowledge about the opening that you can play it at a very fast speed, as well. Here is a third game from our featured anonymous player. It finishes with a bang that is overwhelming - maybe the defender could find a way out, if only he had enough time...

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6
9.Qe3 Nf6 

This position goes back at least as far as the game Charlick - Mann, correspondence, Australia, 1881 (1-0, 72).

10.Nc3 Bd7 

This move is new, according to The Database. It develops a piece, modestly, and avoids percipitating f2-f4, which would have happened after 10...Be6, and avoids forcing White to strengthen his center, with 10...Bg4 11.f3.

11.d4 Kf7 12.f3 Re8 13.b3 Kg8 14.Bb2 

Black has castled-by-hand. White has a solid, but not particularly mobile, center.

14...a5 15.a4 c6 16.h4 

With aggressive intent.

16...Nh5 17.Ne2 Nxh4 

I don't think that the pawn is worth the risk.

18.O-O-O 

The reason he took Kingside liberties with his 16th move: His Majesty is going Queenside, a very reasonable decision that can be made in an eyeblink, even with the risks that sometimes occur when Kings find their homes on opposite sides of the board.

There was also the possibility of 18.Qf2 directly, but it leads to the kind of messy play you might want to avoid in bullet chess: 18...g5 19.g3 Rf8 20.gxh4 g4 21.Rg1 Qf6 22.Ba3 Qxf3 23.Qxf3 Rxf3 24.Bxd6 and it is not clear whose passed pawn is better, and if the whole thing is going to boil down to a Bishops-of-opposite-colors ending that would be quite drawish.

18...b5 19.Nf4 

Tricky, relying on the Rook on the open h-file, but 19...Ng3 is a proper response. Again, he could have considered 19.Qf2.

19...Nxf4

That's the thing about bullet play: aggression is often rewarded because defense takes time to figure out. 

20.Qxf4 Ng6 21. Qxd6 bxa4 22. d5 axb3 

There's aggression on both sides of the board.

23.Rxh7 

"How's that for a kick in the head?", as they used to say.

Stockfish 10 says that Black can take the Rook and still draw, but computers do not live in the real world. I'm pretty sure Black crossed his fingers for luck and played...

23...bxc2 

Grandmasters might play: 23...Kxh7 24.Rh1+ Nh4 25.Qg3 g5 26.Rxh4+ Kg6 27.dxc6 Rc8 28.f4 Rxe4 29.cxd7 Rxc2+ 30.Kb1 Rxb2+ 31.Kxb2 Qf6+ 32.Kb1 Rd4 33.Qg4 Qf5+ 34.Qxf5+ Kxf5 35.fxg5 Rxd7 36.Kb2 Rd2+ 37.Kxb3 Rxg2 38.Ka4 Rxg5 39.Kxa5 and each would then complain about "losing a point".

If it's any consolation, 23...Ne5 24.Rh5 bxc2 would probably lead to a draw, as well.

24.Rxg7+ Kh8 25.Rh1+ Nh4 26.Qh6 checkmate

Very, very nice.

Jerome Gambit: Looks Simple, But It Is Not

In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, the same player from the previous post again tries his best against the "annoying" or "silicon" defense. The line the players explore looks simple, but it is not. 

Anonymous - Anonymous
1 move / 3 days, Chess.com, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 d6 8.fxe5 dxe5 

White has one pawn for his sacrificed piece.

Black's King is annoyingly safe in the center, but White will try batting him around a bit.

This defense was seen as early as the 1993 match between Micah Fisher-Kirshner and the computer program KnightStalker (an early version of ChessBase's Fritz, marketed in the US).

9.Qh3+ Kd6 10.Qd3+ Ke7 11.Qg3 Kf6 

Up until Black's last move, we have been following games where Black was played by computer programs Comet B50, Demon 1.0, Fritz 8, Junior 7, Knightstalker, La Dame Blanche 2.0c, Rybka (v.1 and 2.3.2a), and Zarkov 4.7. None of them chose the move in the game.

What's the problem with the move? Because Black does not want to give up a pawn (11...Kf7 12.Qxe5) he allows the Rook to come to f1, with a check that requires another King move.

12.Rf1+ Ke6 

What is going on?

Well, it's probably not a good idea for White to go pawn-grabbing with 13.Qxg7, as Black not only has the development 13...Nf6, with an even game, he has the sharp riposte 13...Qh4+, when 14.Kd1 Qh5+ 15.Ke1 Qg6 forces the exchange of Queens, and Black's development, activity and Bishop pair give him a clear advantage.

Because computers almost always see White as worse in the Jerome Gambit opening, they constantly look for drawing lines as "best", and, here, Komodo 10 offers one: 13.Qb3+ Kd7 14.Qb5+ Kd6 15.d4 Qh4+ (necessary to move the Queen, otherwise 15...Bxd4 16.Qd5+ Ke7 17.Rf7+ wins it) 16.Rf2 Bxd4 17.Qd5+ Ke7 18.Qf7+ Kd6 19.Qd5+, etc.

So, it's not surprising that White, instead, gives the enemy King another kick, even if it's not objectively the best move.

13.Qg4+ Kd6 14.Qxg7

This capture has its risks. The Queen would probably be safer on g3, but White is not seeking out safety.

14...Ne7 

Protecting the safe Rook. However, after 14...Qh4+ 15.Kd1 Bg4+ White's position would be a mess. 

15.d4 Bxd4 16.c3 

White is still playing with only a couple of pieces, but Komodo 10 rates him as having a slight edge, especially after the recommended return of a piece with 16...Ng6. The reasonable alternative, which Black plays, leads to a difficult position for the defender.

16...Bb6 17.Bg5 

You can almost hear White saying "Gotcha!"

17...Re8 18.Na3 

This Knight means trouble.

18...Be6 

Black needed to try 18...Bg4, but 19.Nc4+ Kc6 (other moves are worse) 20.Qf7 would force him to return a couple of pieces, i.e. 20...Bf2+ 21.Rxf2 b6 22.Nxe5+ Kb7 23.Nxg4.

White's next move settles everything.

19.O-O-O+ Kc6 20.Rxd8 Raxd8 21.Qxe5 Bxa2 22.Qb5+ Kd6 23.Rf6+ Be6 24.e5 checkmate

JeromeGambit: All Is Not Lost

While I think that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is ideal for blitz play - where the defender often does not have enough time to effectively construct a defense - I know a number of players have been successful with the opening at much slower time controls. 

In the following game (time control: one day per move), White faced an opponent who was familiar with the Jerome Gambit, and who did not panic or foolishly over-rate his chances. As the game ground on, the Gambiteer kept alert for his chances, even as the scales begin to tilt against him. Still, he showed faith in the "theory of infinite resistance".

Just at the point where Black reached what the computer, post mortem, mischievously assessed as a "mate in 26" Black slipped - and, with a couple more sacrifices, White reached a drawn endgame.

If you do not laugh out loud (or, at least, chuckle) at White's 47th move, you are taking this whole Jerome Gambit thing too seriously.

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

7.f4 d6

Ah, yes, "the annoying defense" or the "silicon defense". The line is the choice of a number of computer programs, with the idea of giving back one of the sacrificed pieces while leaving Black's King relatively safe - White's attacking chances relatively diminished. Annoying.

8.fxe5 dxe5 9.Nc3 

This move is solid, if somewhat rare, according to The Database. Interestingly enough, 4 of the 7 previous games with the move were played by the computer program Comet B48 in a computer vs computer tournament in 2009. White scored 2 - 2, reasonably enough.

9...Nf6 10.Qe2 c6

A novelty, according to The Database.

11.d3 Rf8 12.Rf1 Kd7 13.Be3 Bxe3 14.Qxe3 Qb6 15.Qxb6 axb6 

White's plan for the middle game is a basic one: to develop solidly, create weaknesses in the opponent's position while avoiding over-reaching. Wasn't it Steinitz who said that if you have the advantage, you must attack - or risk losing the advantage. So, White reasons: let Black attack - let him make the mistakes.

16.O-O-O Kc7 17.h3 Be6 18.a3 b5 19.g4 h6 20.Ne2 Nd7 21.Ng3 Rxf1 

One recommendation I learned long ago was "When you are ahead in material, exchange pieces; when you are behind in material, exchange pawns." For a while, Black seems to be aware of this.

22.Rxf1 Rf8 23.Rxf8 Nxf8 24.Nh5 g6 25.Ng3 h5 

Eliminating the Kingside pawns has to be helpful for White.

White is hanging on. Black is better, but there are not that many pawns to get rid of now.

37.Ne2 Nc5 38.Nd4 Bg2 39.Nxb5 Bxe4 40.b4 Bc6 41.Nd4 Ne6

42.Ne2 

Swapping the Knight for the Bishop would make things worse, as after 42.Nxc6 bxc6 Black would be able to retreat his Knight to c7 and control White's pawns.

42...Kd5 43.Kd2 Kc4 44.Kc2 

I mean no disrespect for the player of the white pieces, as I quote from the very interesting The Complete Chess Swindler, by David Smerdon

I completely agree that a player should try to play the best moves - but I disagree that "best" always equals the engine's first choice. The computer evaluates a position assuming that our opponent will play perfectly at every turn; it doesn't (and cannot) consider the myriad of important human factors in a contest, such as fatigue, time pressure, risk-aversion complacency, frustration, impulsiveness... the list goes on.

44...Nd4+ 45.Nxd4 Kxd4 46.Kb3 b5 

Nailing down White's a-pawn. But - wait!

47.a4 

The move of the game, surpassing even 4...Bxf7+.

47...bxa4+ 48.Kb2 Kc4 49.b5 Bxb5 50.Ka1 Kb3 51.Kb1 drawn

Yes, indeed. The game has reached the notorious "Rook pawn + wrong Bishop" ending, which is drawn because White's King can control or occupy the pawn's Queening square, and the enemy Bishop is of the wrong color to chase him out.

Very well played!
