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.

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


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.

26.gxh5 gxh5 27.Nxh5 Bxh3


28.Kd2 Ne6 29.c3 Nf4 30.Ng3 Kd6 31.Ke3 c5 32.d4 cxd4+ 33.cxd4 Ng2+ 34.Kd3 Nf4+ 35.Ke3 Ne6 36.dxe5+ Kxe5 



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!

Jerome Gambit: Help Is Always Appreciated


When winning with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), it is always tempting to attribute our success to the brilliance of the attack. Sometimes, however, the defender contributes as well. In the following game, Black does quite well - until he doesn't.

9.Qf4 g5

It is always attractive to attack the enemy Queen. Oddly enough, Komodo 10 recommends, instead, that Black return his King to e6.

10.Qg3 Bxf2+ 

Rather than allow the pawn fork d2-d4.

11.Kxf2 Qf6+ 12.Ke2 Qf4 



To exchange Queens, a sound strategy. 

13.d4 Nc4

One of those kinds of oversights that happen in 3-minute games.

Jerome Gambit: Winning in the End

The well-rounded Jerome Gambit player knows his opening, but he also knows how to play the middle games that could arise, and he is ready to carry the fight into the endgame.

The following game shows the "1-0" arising from the threat to promote a passed pawn in a Rook and pawns endgame.

10.d3 Kf7 11.Bg5 Be6 

Black is happy to further his development, but this Bishop placement, along with the Knight at g6, encourages White's next move.

12.f4 h6 13.Bxf6 Qxf6 14.Qxf6+ Kxf6 



Black captures with his King to keep his Kingside pawns intact.

15.f5 Nf4 16.fxe6 Nxg2+ 17.Kf2 Nf4 18.Ke3 Nxe6 



The game is balanced. White is going to have to out-play his opponent. This is a 5 minute game, and the surprise and strangeness of the Jerome Gambit may have given him a lead on the clock.

19.Rf1+ Ke7 20.Nc3 Raf8 21.Nd5+ Kd7 22.a4 c6 23.Nf4 Nxf4 24.Rxf4 Rxf4 25.Kxf4 Rf8+ 26.Ke3 Ke6 27.Rg1 g5 28.h4 gxh4 29.Rh1 Rh8 30.Rxh4 h5 



Black's h-pawn has no future. The game is still even, and it is hard to know if White is disappointed because he doesn't have a checkmating attack, or relieved that he is no longer down two pieces. In any event, he presses on.

31.Kf4  Kf6 32.d4 a5 33.e5+ dxe5+ 34.dxe5+ Kg6 



35.e6 

Premature, but he gets away with it.

35...Rf8+ 

Forcing White's King to go where he wants to go. Black would have all the chances after 35...Kf6.

Jerome Gambit: How Much A Victory For Black?


If White is looking to play a wild attack in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), how much of a victory is it for Black to deny him that? What is the appropriate "price" to pay?

In the following game the defender might have felt pleased that he was not over-run by enemy pieces, but he still had a game to win - or draw. By the time he had made any progress on that goal, it seems he might have tripped over his clock, in which case, White was quite happy to show how to secure the win, and it only cost Black a full point.

Usually the counter-sacrifice at f2 is followed by an exchange of Queens, to reduce White's attacking chances, even if that means that Black is, in effect the one offering a gambit.

It is unclear if Black was trying (mistakenly) for a repetition of moves here (if so: the clock) or if he just overlooked 26...Nxf3, since 27.Rxf3 would have been met by 27...Bg4.

In any event, White is happy to exchange places, as it were - he will now have the extra piece for a pawn, with more material to come.

Blackburne Shilling Jerome Gambit: Objective and Subjective

When putting together a Jerome Gambit repertoire, it is useful to have access to both "objective" evaluations - say, from a computer chess engine - and "subjective" evaluations - as from a collection of games that can tell you how successful a line has been. Often a move that is not "objectively" best may score very well in actual play. The following game, and its notes, illustrate this.

White's strongest move, "objectively", is 6.c3. The Database has 392 games with 6.c3, with White scoring 62%.

6...Kxe5 7.f4+ Kxe4

One of the reasons White plays 6.Qg4, is so that if Black grabs the Knight, he can offer more material with 7.f4+, because if Black grabs the e-pawn... What happens next??

Don't worry. White was asked this question 24 times in The Database, and only scored 50 %.

Wait until next time! That's why I analyze games and share them. 

8.d3+ Kd5 9.c4+ Kc6 10.O-O Nc2 



There is nothing exactly wrong with this move, but shouldn't Black be thinking about safeguarding his King, not grabbing more material? If I were White, even though I was down 2 pieces, I would feel a stirring of hope.

11.Qf3+ Kb6 12.Qf2+ c5 

Proof that Black considers the game already won. Otherwise, what move would he have played that definitely would have produced "resigns"?

13.Qxc2 Qf6 

Amazingly enough, now, with 14.Nc3 (with the plan to go to d5) White would equalize.

Jerome Gambit: Easy Does It

Black believes he has trapped White's offside Knight. He is mistaken. In his attempt to hold things together, he surrenders his advantage. 

11.Qb3+ d5 

Bill suggests 11...Kg6 12.Qxb5 Qe8 and White has grabbed the pawn, but he still has work to do.

12.Qxb5 Qd6 

This move doesn't work. Why not?

White is now ahead 3 pawns, and Black's Bishop pair and slightly better development are not adequate compensation.

This looks like a simple attempt to exchange his Bishop for the Knight, but it is more than that.

Very nice.
