Jerome Gambit; Back Again

Chessfriend angelcamina is back with another Jerome Gambit game played online at "bullet" speed - one minute, with no increment.

I tend to rephrase the question "Is the Jerome Gambit playable?" into something like "Under what conditions is the Jerome Gambit playable?" Bullet games like the following tend to expand my understanding as to what the answer is.

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

17.Qf3 Nf5 18.Qxd5+ Be6 19.Qc5 c6 20.Nc3 Nxf4


A tactical slip, but, at the speed this game was unfolding, I wouldn't be surprised if the defender had yelled out "Three no trump!" instead.

Now, White takes command.

Checkmate is coming.

Jerome Gambit: Opposite of Expected

The following Jerome Gambit game must have annoyed Black to no end. After playing White even for most of the game (okay - it was a slip for the defender to allow the game to become "even"), he reached a Bishops-of-opposite-colors endgame, only to be tripped up by the presence of an additional Rook on each side. The extra material gave the position middlegame features, specifically that the side on the attack is helped by the opposite-colored Bishops.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6


8.O-O Qf6 

Just checking to see if White is paying attention... 

9.Be3 

He is. The threat was 9...Nf6+, winning White's Queen. 

9...Ne7 10.Nc3 Rf8 11.Nb5 



Black was making progress, moving toward castling-by-hand. It was time for White to shake things up a bit. Black's Queen usually is closer to home, and can deal with threats to c7, but that is not the case, here.

11...N7c6 12.Qd2 Qe7 13.Bg5 Qd7 14.f4 Ng6 



White has gotten to play two of his usueful moves, Bg5 and f2-f4, and had to be happy to see one of the typical "germs" of trouble for Black: the Queen blocks the Bishop which blocks the Rook.

Black is still probably better, but White has the more comfortable position to play. 

15.Qd5+ Ke8 16.e5 dxe5 17.Qxd7+ 

This exchange of Queens may have come as a surprise, but now the King blocks the Bishop that blocks the Rook... 

17...Kxd7 18.f5 Nge7 

19.Rad1+ Nd4 20.Nxd4 exd4 21.Rxd4+ Ke8 22.Re1 Rf7 23.Rde4 Bxf5 24.Rxe7+ Rxe7 25.Rxe7+ Kf8 26.Rxc7 Be4 


Take the Rooks off of the board, and the extra pawn for White is virtually meaningless. Sure, White can still outplay his opponent, but that's a different story.

27.Be7+ Kg8 28. Bb4 Bc6 29.Bc3 g6 30.Rg7+ Kf8 31.Rxh7 b6 32.Rc7 Bb5 33.h4 Black resigned



In club play, especially with the clock ticking, it is sometimes possible to draw a Bishops-of-opposite-colors endgame two pawns down. Here, however, White's Rook ties down Black's Rook (it will cost a pawn to be freed), while confining Black's King to the back rank, limiting its ability to assist in a defensive blockade.

Jerome Gambit: Missing Ingredients

Black is by no means doomed in the Jerome Gambit. (That's a joke. The Jerome has multiple refutations.) However, the defender needs to stick to the basics of defense (or rampant counter-attack) and not neglect an ingredient or two - an oversight can turn the game around and bring about a painful ending.

Wall, Bill - Guest2783012
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.Nc3 Nf6 9.O-O Be6 

Black is doing fine. White has to pull a few tools out of his "toolbox", perhaps Bg5 or f4, to keep pursuing his chances.

10.f4 Nc6 11.Qd3 Nb4 

The position of White's Queen is too tempting, Black's Knight must kick it. There is the bonus attraction of the chance to attack White's Rook at a1, so Black dives in. He only risks arriving at an even game, but that is too much to give up - he should have continued the typical castle-by-hand with ...Re8 and ...Kg8.

12.Qb5 Nxc2 13.f5 

This looks like desperation, but White knows what he is doing. 

13...Nxa1 14.fxe6+ 

14...Ke7

Black suddenly realizes that something is up, but 14...Kxe6 or 14...Kg8 were ways to stay in the game. Putting his King where the Knight can be pinned to it is asking for trouble.

15.Bg5 Rf8 16.e5 dxe5 17.Qxe5 Ke8 



This probably looked like some kind of solution, but it is not.

18.Bxf6 gxf6 19.Qh5+ Ke7 20.Qxh7+ Kxe6


Checkmate follows. 

21.Re1+ Kd6 22.Qd3+ Kc6 23.Qc4+ Kd7 24.Qe6 checkmate

Jerome Gambit: A Quick Reversal of Fortune

It is nice to surprise your opponent with the Jerome Gambit.

Sometimes, though, that opponent is not only not surprised, he has prepared a special reception. Then, the attacker has to rely upon his knowledge of the Jerome, plus his own skills, to make sure that the game turns out right.


Wall, Bill - Guest2773994
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 



8.Qd5+ 

White is willing to go after the b-pawn - and Black encourages him to do so.

8...Be6 9.Qxb7 Nf6 10.Nc3 Bc4



A tricky move that appears to be a novelty, according to The Database. Black does not want his opponent to castle. He also limits White's Queen's retreat squares. Previously, Bill has seen 10...Qe7, 10...Qd7, 10...Re8 and 10...Rf8.

11.b3 Rb8 12.Qxa7 Nd3+



Wow.

Black seems to have a low opinion of the Jerome Gambit, or his opponent, or both. This is a very optimistic sacrifice of a piece - but, in all fairness, Black does have an "extra" one to give back.

13.cxd3 Bxd3

White's King is still in the center, Black's pieces attack the pawn at e4, and Black's Rook and Queen are ready to swing over to the e-file.

14.Bg5 Qe7 15.Rc1 Rhe8 16.f3 



Black's attack is beginning to look a bit scary, although the computers are not impreseed. Unfortunately, Black's next move appears to overlook the pin on his Knight.

16...d5

Now White strikes quickly.

17.Nxd5 Qe5 18.Rxc7+ Kg8 19.Rxg7+ Kh8 20.Bxf6 Black Resigned

Jerome Gambit: Direction

There is an old saying (more of a warning): If you keep on heading in the direction you're going - you'll get there.

The following game shows Black taking an interesting step toward the unknown - but he does not continue. As a result, the game ends pretty much as expected.

Wall, Bill - Guest2781227
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Ke8 

Black decides that the gift of one piece is enough, thank you very much. This is not a "refutation" of the Jerome Gambit, but it is the kind of move that can set White to thinking, if he is not familiar with it.

6.Nxc6 dxc6 

The recommended move, instead, is the wild 6...Qh4!? which would lead to a complicated game where White might have a small edge. Not surprisingly, The Database still has no game examples.

The problem with the "normal" text is that it allows the first player to just go about his business.

7.Qh5+ g6 8.Qxc5 Qd6 

An exchange of Queens might break White's attack, and straighten out Black's Queenside pawns, but it would simply leave him down a couple pawns. Still, Bill is not interested in helping out.

9.Qc3 Qf6 10.d4 Qe6 11.O-O Nf6 

If this game were a scary movie, this is about where the ominous background music would begin.

The e-file and the a1-h8 diagonal have problems for Black, and resolving those issues will open up other points of danger.

12.d5 cxd5 13.exd5 Qd6 14.Re1+ Kf7 15. Bg5 Bf5 16.Bxf6 Qxf6 17.Qxc7+ Kf8 18.Qxb7 Black resigned



White is 4 pawns up. Black's King remains at risk. The direction that the game will take is clear.

Italian Battleground: Round 3

Round 3 has started in the Chess.com "Italian Battleground" tournament, and I will be battling with docfb, 275Jukka,warwar, Abhishek29 and XristosGikas.

In my first 5 (concurrent) games, I have the black pieces 4 times, and in my 1 game with White, I am playing a Hungarian Defense - so, no Jerome Gambit so far. 

In Round 1, I scored with the Jerome against Abhishek29, and in Round 2 I did the same against warwar. It will be interesting to see if they let me play my refuted opening again - and, if so, what improvements they have come up with.

In Round 2, docfb played a Two Knights Defense, and beat me. I wonder if he will be satisfied to repeat, or if he will go with the easy win against the Jerome.

As for 275Jukka, we have not played before, but he went for the Hungarian Defense 3...Be7 right away. He must have a really good track record with the Hungarian, to turn down the offer of two pieces that allowing the Jerome Gambit would have achieved.

XristosGikas is new to me, as well, so perhaps he will oblige me and "blunder" into a win after 4 moves...

Jerome Gambit: Probably Not This, Either

As I have explored the history, games, and analysis of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), I have also looked for earlier opening examples that might have inspired Alonzo Wheeler Jerome to create and share his opening. This blog has many examples of possible Jerome Gambit instigators.

In this post I want to share some lines that most likely were not precursors of the Jerome. Purists can move on to the next blog post. Those who like fun chess - well, stick around.

For Christmas, my wife gave me Tim Sawyer's book Queens Knight 1.Nc3 & 1...Nc6 Second Edition Chess Opening Games (2018). I am familiar with Tim's work on the Blackmar Diemer Gambit (1.d4 d5 2.e4) but I see, of late, he has expanded to coverage of a whole range of openings.

Early on in the book, I encountered
The game Laird vs Bullockus began 1.Nc3 e5 2.Nf3 Bc5 3.Nxe5. What can Black do? The answer is a bishop sacrifice 3...Bxf2+! 4.Kxf2 Qh4+ and the Black queen will regain the piece on e5. 
This was a postal game between two California players. Scott W. Laird was a master in correspondence and in tournament play. 
Dr. Theodore Bullockus was an international arbiter and longtime postal chess player. His peak ICCF rating was 2299. 
Ted Bolluckus was a teammate of mine in the Correspondence Olympiad. We represented the USA in the 1980s. 
The Queens Knight Attack opening line is actually the reverse of an Alekhine Defence variation. Ted Bullockus was an expert in the Alekhine. In fact he influenced me to study it for many years. 
The Alekhine line goes 1.e4 Nf6 2.Bc4 Nxe4 3.Bxf7+ Kxf7 4.Qh5+ when White regains the piece on e4 with equal chances. In the Queens Knight Attack White has the added useful move 1.Nc3.
1.Nc3 e5 2.Nf3 Bc5 3.Nxe5 Bxf2+ 4.Kxf2 Qh4+ 5.g3 Qd4+ 6.e3 Qxe5 7.Qf3 Nf6 8.d4 Qe7 9.e4 d6 10.h3 0-0 11.Bc4 Nc6 12.Be3 Re8 13.a3 Kh8 14.Bd3 Be6 15.g4 Nd7 16.d5 Black resigned

Enjoyable, if not successful chess - this time.
