Jerome Gambit: Pressure, Tactical Error

The Jerome Gambit can apply pressure, until a slip leads to a tactical error, and White records another win.

Wall, Bill - Ahmad

internet, 2023

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

4...Kxf7 5.O-O 

A "modern" Jerome Gambit, as opposed to Alonzo Wheeler Jerome's "classical" 5.Nxe5+ - but wait.

5...Nf6 6.Nxe5+ Nxe5 7.d4 Bd6 

8.dxe5 Bxe5 9.f4 Bd6 10.e5 Bc5+ 11.Kh1 Ne8 

The "Jerome pawns" have won the battle for the center against the enemy pieces, and now the Queen moves in to grab a loose piece.

12.Qd5+ Kf8 13.Qxc5+ 

Okay, White is better, but, after a breather, the pawns have more work to do.

13...d6 14.Qb4 b6 

15.f5 Bb7 16.f6 gxf6 17.Bh6+ Kf7 18.Qc4+ d5 19.Qg4 Rg8 

Overlooking something.

20.e6+ Ke7 21.Qxg8 Black resigned

Jerome Gambit: Stumbling and Tumbling Knights

In an even Queenless middle game, Black's Knights stumble and tumble and give the game away.

To be sure, Bill Wall, with the White pieces, had a hand in that, too.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6  

Here we have a standard Jerome Gambit position, one that appears over 700 times in The Database, with White scoring 66%.

10.f4 Ng4 

This is not a "bad" move for Black, but it is another example of the defender deciding to harass the Queen.

11.Qg3 Qe7 

Consistent would have been 11...Qh4 12.Qxh4 Nxh4, with an edge to Black.

12.O-O Rf8 13.d3 Qh4 

Deciding upon the exchange after all.

14.Qxh4 Nxh4 

White has two pawns for his sacrificed piece. The game is even.

15.h3 Nh6 16.Nc3 c6 17.f5 

Hunting the Knights.

17...g5 

A slip. Instead, 17...N4xf5 18.exf5 Bxf5 19.Be3 would have led to an edge for White. 

18.Bxg5 Nxg2

Things would open up too quickly after 18...N4xf5 19.exf5 Nxf5 20.Rae1+.

 19.Bxh6 Rf6 20.Bd2 Nh4 21.Bg5 Black resigned

BSHG: Know Your Defense

In the following game, White is more familiar with the Blackburne Shilling Jerome Gambit than Black is with the Blackburne Shilling Gambit. The result is predictable.

Jerome Gambit: Harassed

I have seen Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games where White's Queen is harassed, but I  don't think that I have ever seen anything like the following game.

 angelcamina - pekasmed

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

22...Qxd5

I am not sure if this was a mouse slip or an oversight or because this is a bullet game. In any event: Game Over.

Instead, 22...Bxd5 23.exd5 Qxd5 maintained Black's advantage

Jerome Gambit: Funniest Jerome Gambit

Yury V. Bukayev sent me what may be the funniest Jerome Gambit ever played. Sure, the players are children, and the Jerome is an excellent choice for them, but, still...

D.K. - P.B.

EU-ch U08 Germany, 2003

1.e4 e5 2.Bc4 Nc6 3.Bxf7+ Kxf7 4.Nf3 Bc5 

Reaching the Jerome Gambit via the Bishop's Opening.

5.O-O Bxf2+ 

Well, that came as a surprise. More psychology?

6.Rxf2 Nd4 

A painful mis-step.

Not surprisingly, The Database has another game with the much more normal 6...Nf6: 7.Ng5+ Kg8 8.c3 d6 9.Qb3+ Kf8 10.Qf7 checkmate, UmusBdreamin - QFM, FICS, 2008. 

7.Nxe5+ Ke8 

Okay, White is in control, with more material and a coming attack on an unsafe King. What would you do?

8.Rf7 

Planting a Rook in enemy territory, but leaving himself open for the counter 8...Qg5!?.

Strongest was adding the Queen: 8.Qh5+ g6 9.Nxg6 Nf6 10.Qe5+ Ne6 11.Nxh8 d6 12.Qxf6 Qxf6 13.Rxf6.

Even 8.Nf7 was better motivated. 

8...Nh6 9.Nc3 

White is right, the Rook does not have to move, but this is not the correct choice - 9.Qh5 was. 

9...Rf8 

Looking to eject the enemy Rook, but this was also a mistake. 

10.Rxg7 

10...Rxf8+ with advantage to White.

10...Rg8 

The Rook has a job, and it intends to do it, wrong-headed as ever.

Instead, 10...Qf6! 11.Qh5+! Kd8!, where White has some advantage, but he will need to find the best moves to keep it, because the position is sharp.

11.Rxg8+ 

Why not? White sees nothing wrong with cooperating with Black, here.

You probably saw that he also had 11.Qh5+ Kf8 12.Rf7+ Ke8 13.Rxh7+ Kf8 14.Qxh6+ Ke8 15.Qh5+ Rg6 16.Qxg6+ Kf8 17.Qf7# 

11...Nxg8 Black resigned

12.Qh5+ leads to checkmate.

Jerome Gambit: A Few Tactical Ideas in Your Pocket

It is always good to have a few tactical ideas in your pocket - you never know when they might come in handy. 

The following game is won by such an idea.

Mauricio060215 - Cpt_Joseph

5 0 blitz, lichess.org, 2023

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

 4...Kxf7 5.O-O 

This is one of the so-called "modern" variations of the Jerome Gambit, because Alonzo Wheeler Jerome and early players all focused, instead, on 5.Nxe5+.

White decides that sacrificing one piece is enough.

The Database has 1,971 games, with 5.O-O. White scores 41%.

It has 20,917 games with 5.Nxe5+. White scores 57%  

But our silicon friend suggests that the story is not over. At 40 ply, Stockfish 15's analysis is that 5.Nxe5+ is only .2 of a pawn better than 5.O-O. That's not much of a difference at all.

The question should be: How wild a game do you want?

5...Be7 

Black has defensive plans.

6.c3 d6 7.d4 Nf6 

8.dxe5 dxe5 

Okay, thinks White, let's try something

9.Qb3+ Be6 

Bingo!

So many defenders against the Jerome Gambit love to harass the White Queen.

But White is ready.

10.Ng5+ 

Of course.

Rememer, this is a 5 minute blitz game. Such a thing is less likely to occur with longer time controls.

10...Kg6 

Black flees his castle behind a wall of pawns.

11.Qxe6 Rf8 12.Qf5+ Kh6 13.Nf7 checkmate

Very nice.

Win and Lose With the Bishop Sacrifice Gambit!

Yury V. Bukayev directed me to Michael Tam's "Adventures of A Chess Noob" website, subtitled, appropriately, "learning and having fun with chess!"

In particular he wanted me to see "Win and lose with the Bishop sacrifice gambit!" This was not a particular opening, but, as Mr. Tam pointed out, a thematic idea that can occur in a number of openings. "This is best characterized by the Jerome Gambit" he says, although he adds "The Jerome Gambit is completely unsound, I don't recommend it."

The rest of the video is Mr. Tam showing two games, one where he  defended a Two Knights defense and one where he played a Vienna Gambit. Both featured the Bishop sacrifice.

He sagely suggests that you make the sacrifice "only if you have an immediate attack that can take advantage of the exposed King". That has always been a criticism of the Jerome. (It is also why White often follows 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 with the further sacrifice 5.Nxe5+ and attack, i.e. 5...Nxe5 6.Qh5+)

I recommend visiting the site (with some stunning graphics), which has many videos about many openings, and especially watching Mr. Tam play over the second game, the Vienna Gambit. It is truly wonderful to hear Mr. Tam talk about how Stockfish continues to rate the defender as doing far better, move by move, even though you are watching the pieces on the board and you know that you are seeing him crush his opponent.  

Happens in the Jerome Gambit, too, I have to add.
