Jerome Gambit: Lessons From the Grandmaster's Games (Part 1)

A quick look at the following 3-minute Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game by Grandmaster Hikaru Nakamura, from one of his speedruns (see "Jerome Gambit: Speedrunning Tricks") provides a few lessons for the developing club player.

GM Nakamura - NN

3 0 blitz, internet, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

Maybe the GM's opponent is familiar with the Jerome, and this is his favorite defense; maybe he just wants to hang onto material.

7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 

The Database shows 50 previous games with this position, including ones in which Alonzo Wheeler Jerome plays against Shinkman, Brownson, Amateur, Jaeger, Paine, Colburn and Charles. Both players appear to have a feel for the opening.

10...Ne7 

Reasonable, but 10...Nf6! was stronger. 

11.c3 Ng6 

Black believes that he has prepared for the coming pawn advance, but he has overlooked something. An even game was to be had with 11...Qf6 

12.d4 Rf8

White's pawn forks the enemy Queen and Bishop, but Black's Rook attacks White's Queen. Is that enough for the defender?

13.dxe5+ 

Capturing with check, the kind of thing that can be overlooked in the calculations in a 3-minute game.

13...Kxe5 14.Qh5+ Kd6 15.Qd5+ Black resigned

White will pick up another piece, and be a Queen ahead.

Jerome Gambit: Speedrunning Tricks

 

I enjoy playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

I enjoy playing over the Jeromes that Readers of this blog send me.

I enjoy watching Jerome Gambit games.

I have especially enjoy watching videos of Grandmaster Hikaru Nakamura playing 3-minute games, one after the other, using "tricks" - risky gambit openings - to defeat his opponents.

Of course, some of those games are Jerome Gambits.

I recommend:

"Speedrunning to 3000 With Tricks Only"

"Hikaru Jeromes his way Through 1200s"

"Hikaru Tricks some 1500s"

"The 1600s DENY Hikaru any Fun"

"GM Hikaru on 1900s: They Don't Make Em Like They Used To"

You might object Of course GM Nakamura would be successful against weaker players, even while giving them "Jerome Gambit odds!"  But that is exactly my point. 

Play along with him, stop the video at different points in the game, ask yourself what moves you should make, then start the video and see how the GM proceeds.

All the games the grandmaster plays are fun. I especially like the Jerome Gambits.

Jerome Gambit: Tactics Real And Imagined

The following Jerome Gambit (by transposition) game shows an attack that wins quickly. The notes show that the tactics could have been sharpened, with equal danger for the defender.

A win is a win is a win.

3 0 blitz, FICS, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.O-O Bc5 5.Bxf7+ 

Starting out as a Two Knights Defense, the opening moves to a "modern" variation (no 5.Nxe5+) of the Jerome Gambit - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6.

5...Kxf7 

The Database has almost 2,500 games with this position.

6.c3 Rf8 7.d4 exd4 8.cxd4 Bb6 

9.e5 Ne8 

A slip that goes unpunished. Black needed to play 9...Nd5.

10.Qb3+ 

Reasonably interfering with Black's plan to complete castling-by-hand with ...Kg8.

Stronger was 10.Bg5 first, and if 10...Ne7, then 11.Qb3 would force the King out into the open. 

10...d5 11.exd6+ Be6 

Black had to try 11...Kg6 which would be well met by 12.d5, with advantage to White.

12.d5 Na5 13.dxe6+ Kg8 Black resigned

Black realized that he could now meet 14.e7+ with  14...Nxb3, but after 15.exd8/Q Rxd8 16.axb3 Nxd6 he would be down a piece.

One temptation that afflicts many who defend against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is to attack White's Queen - not so much as part of a larger plan, but simply because the defender can.

In most cases, the offending piece is the Knight.

In the following game, instead of retiring politely, Black's Bishop repositions itself in order to attack the enemy Queen. The move is part of a plan, but it fails, nonetheless.

A pleasant Jerome Gambit blitz win.

Robepersky - anzali

5 0 blitz, FICS, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 Qe7 

This position is as old as Jaeger - Jerome, correspondence, 1880 (0-1, 14) and Jaeger - Jerome, correspondence, 1880 (0-1, 40).

8.Qf4+ Nf6 9.c3 d5 10.d4 Bd6 

The Bishop attacks White's Queen, while also aiming at the enemy Kingside. With a 3:1 piece development advantage, Black feels comfortable.

However, White's "Jerome pawn" messes things up.

11.e5 Kg8 

Black immediately breaks the pin on his Knight. Also possible was 11...c6 12.0-0 Bb8 13.exf6 saving the Bishop and giving up the Knight, when White would have a slight edge. 

12.O-O Nh5 

Now the Knight attacks the Queen, but the tactics are not on its side.

13.exd6 Nxf4 14.dxe7 Ne2+ 15.Kh1 Nxc1 16.e8=Q checkmate

Jerome Gambit: One Mistake

Club players - and even masters - know that the game isn't over, just because you made one mistake. There is usually time to fix things.

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is an excellent example.

RaenKid - dtz90

5 0 blitz, Chess.com, 2021

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4... Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7 

The annotation from Chess.com correctly labels this a 
"Critical move". This is Whistler's defense, as opposed to Blackburne's defense, 7...d6.

The players have a complicated game ahead of them. It is recommended that White not capture the Rook.

8.Qxh8

The difficulty with this move is that now 8...Qxe4+ is very dangerous.

8...Nf6 

dtz90 does not get any support from the notes. This move is described as "From winning to losing." 

9.d3

RaenKid recovers quickly.

Both players now make plans to attack the enemy King.

9...Qe5 10.Bh6 Qd4 

This looks scary, but White has everything under control.

11.Qg7+ Ke6 12.Be3 Qxb2 13.Bxc5 Qxa1 

Just has he has planned, Black has almost drawn even with his opponent when it comes to material. However, that is largely irrelevant.

 

14.Qe7 checkmate

The end of the game is a bit ironic: White's capture of a Rook should have put his King in great danger; Black's capture of a Rook finished the game, due to checkmate.

Jerome Gambit: The Little Things Add Up

The following game is a good example of how the little things on defense in a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game can add up to a significant advantage for White, over time. 

Wall, Bill - Yapwx

internet, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+

I am not saying that this is a bad move, but The Database shows that Bill is 45 - 0 against it. (Better was the straight forward 6...Bxd4.) 

7.c3 Bxc3+ 

Facing 6.d4, Black had to return a piece. This is how he does it.

8.bxc3 

In the past Bill has shown a preference for 8.Nxc3, although he has occasionally played the text.

8...Ng6 9.O-O d6 

Black plays defensively / preventively against White's pawns. He might have tried 9...d5 with the idea that if 10.e5, he could blockade the advanced pawn.

10.f4 Ke8 

Getting off of the dangerous f-file.

11.Qf3 

Already we see a premonition of White's winning move. 

11...N8e7 12.f5 Nh4 

It can not be a good thing to waste time annoying the enemy Queen, when you are lagging in development. White's punishment is swift.

13.Qh5+ Nhg6 14.fxg6 Nxg6 15.Nd2 

Material is even, but development and King safety clearly favor White.

15...b6

 How to go about developing the Bishop? Not this way.

16.Qd5 Rb8 17.Qf7 checkmate
