Jerome Gambit: Theory Helps

 

One thing that attracts players to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is that it quickly side-steps Italian Game theory and allows for (requires) creativity in play.

That having been said, the theory of the Jerome Gambit continues to develop and there is some value in being aware of it, if only to be able to avoid problems like those that occur in the following 3-minute blitz game.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 

Now White can capture the Bishop, and prevent the freeing ...d5.

7.f4

According to The Database, this is a new move.

According to Stockfish 13, Black is now more than a Queen better. 

How does Grandmaster Hikaru Nakamura demonstrate this?

7...Qh4+ 8.g3 Qg4 

Give the position a long look. 

White can quote Joe Jacobs "I should of stood in bed".

9.fxe5

The troublsome thing is that after, say, 9.Nd2, Black can swap Queens with 9...Qxd1+ 10. Kxd1 and then 10...Ng4 leaves him up two pieces with little danger facing him.

9...Qxe4+ 10.Qe2 Qxh1+ 11.Kd2 Qd5 

12.c4 Qxe5 13.Qf3+ Nf6 14.a3 d5 

15.b3 Bg4 16.Nc3 Bxf3 17.Bb2 White resigned

There is a checkmate in 5 moves.

Jerome Gambit: Maniac Alert

If the defender in the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is indeed a "bullet maniac", then he adopted the correct strategy in his 3-minute blitz game against Grandmaster Hikaru Nakamura - attack, attack, attack.

That he was ultimately not successful was neither the fault of his plan, nor the vindication of the Jerome Gambit, but, rather, the fact that he was playing such a strong opponent.

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

Black plays Whistler's defense, offering the Rook for a brutal counter-attack after 8.Qxh8?! Qxe4+.

It was interesting to watch GM Nakamura consider his next move, while asking himself "Is this a trick or is he bluffing?"

8.Qf4+ 

"I don't think he's bluffing," Nakamura decided, rightly. "I think this is some kind of weird prep."

8...Qf6 9.Qg3 Bd6 

Pure aggression. Its is a rare move, appearing only in Wall,B - Guest3289310, PlayChess.com, 2012 (1-0, 38) and Wall,B - Guest744598, PlayChess.com, 2020 (1-0, 22).

13.g3 Bd6 14.d4 Nf5 15.c3 Kg7 16.Qd3 b6

Black returns a piece to continue his development. His two Bishops, especially the one headed for the a8-h1 diagonal, look powerful.

17.exf5 Bb7 18.Nd2 gxf5 19.f3 Kh8 20.Nc4 h5 

Still more aggression. White now removes one of the dangerous Bishops.

21.Nxd6 cxd6 

Necessary, as the Queen capture would lose the pawn on f5. However, the shaky nature of Black's pawn structure will eventually become significant.

22.Bf4 h4 23.Rae1 h3 24.Kf2 Kh7 25.g4 Qh4+ 26.Bg3 Qg5 

27.Qxf5+ Qxf5 28.gxf5 Ba6 29.Rg1 Kg8 

Stepping into danger. 

30.Be5+ Kf7 31.Rg7+ Kf8 32.f6 

White's Bishop can afford to pretend that it's a "Jerome pawn".

32...dxe5 33.dxe5 Bc4 34.f4 

Opening the way for White's Rook to travel to the h-file.

Jerome Gambit: Annoying GMHikaruOnTwitch

Some variations in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can benefit from whatever light a Grandmaster can shine upon them. Below, GM Hikaru Nakamura shares his experiences.

GMHikaruOnTwitch - GM_xAhmedx

3 0 blitz, Chess.com, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6

The silicon or annoying defense, so-called because computer programs like it - and it can be particularly annoying for White. While returning a piece, Black's King is allowed to hang out in his advanced position, while forcing him back does not seem to do much damage to the defender. In the meantime, White has to take steps to be able to castle Kingside, while Black's two Bishops can cause problems.

8.fxe5 dxe5 9.Nc3 

The best move, according to Stockfish 13, is the uncomfortable 9.Qh3+. Even if White manages to subsequently capture the enemy e-pawn, it doesn't help much.

White has also tried 

9.d3 Nf6 10.Qh4 h6 11.Nd2 g5 12.Qg3 Bd7 13.Nf3 Rg8 14.Qxe5+ Kf7 15.Qxc5 b6 16.Qc4+ Kg7 17.O-O c5 18.Nxg5 hxg5 19.Bxg5 Rf8 20.e5 Black resigned, GMHikaruOnTwitch - Romanov205, 3 0 blitz, Chess.com, 2021; and

9...Nf6 10.Qf5+ Kf7 11.Qxe5 Bf2+ 

Like I said: annoying.

12.Kf1 Bd4 13.Qf4 Kg6 

A bit of a tease. If need be, Black can soon castle-by-hand.

14.Ke1 

White could be a bit more aggressive with 14.Qh4, but after 14...Rf8 15.Ke1 h6 16.d3 Kh7 his own King is the one that is uncomfortable.

14...Re8 

The "Jerome pawns", often a dynamic factor on White's behalf, are now stifled.

The following moves, however, show that Black is not quite sure how to take advantage of his advantage.

15.d3 Ng4 16.Rf1 Be6 17.Qg3 c6 18.h3 Qa5 19.Bd2 Qe5 

 20.Rf4

White's best, according to Stockfish 13, was to enter the wild complications after 20.Bf4 Bxc3+ 21.Ke2 Bxb2 22.Bxe5 Bxe5 23.Qe1 Bxa1 24.Qxa1 Nf6 when he would have a Queen and a pawn against a Rook, Bishop and Knight; but he would have play against the Black King, e.g. 25.e5 Nd7 26.Qd4 Nxe5 27.Qe4+ Kh6 28.Kd2 Nd7 29.Qh4+ Kg6 30.Qe4+ with a draw by repetition.

20...Bf2+ 21.Qxf2 Nxf2 22.Kxf2 Rf8 23.g3 Bxh3 24.Ne2 Qxb2 25.Bc3 Qxc2 26.Ke3 Rad8 White resigned

Jerome Gambit: Fearless.

In the following 3-minute blitz Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Grandmaster Hikaru Nakamura fearlessly enters a dangerous line of play and skillfully manages a balance of attack and defense to take the full point. 

GMHikaruOnTwitch - 30second-guy

3 0 blitz, Chess.com, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 

I don't have an official name for this line of play, first seen, according to The Database, in Sorensen - X, Denmark, 1888 (1-0, 27), but I have referred to it as a "pie-in-the-face variation" for obvious reasons. If White is expecting either enemy piece to retreat from the center and save itself, he has to find the Queen excursion - usually the territory of White in the Jerome Gambit - to be somewhat of a humorous, if dangerous, surprise. 

7.O-O Qxe4 8.dxc5 Nf6 9.Nc3 Qf5 

You can already imagine which Black Knight is planning to move to g4 to help deliver checkmate by the Queen at h2.

10.Nb5 

If a student played this move, his teacher would no doubt consider him insolent. While the move does not "save" the game, it is considered best by Stockfish 13, and it packs a lot of psychological impact - White is not going to cower in response to the impending counter-attack.

10...b6 11.Nxc7 Bb7 12.f4 

Encouraging the Knight along its way, but dangerous, nonetheless, as Black now has 12...Nf3+! 13.gxf3 Qxc5+ 14.Be3 Qxc7 winning a pawn, breaking up White's Kingside and getting rid of that pesky Knight. However, this is a 3-minute game, and not every tactic is visible.

12...Neg4 

13.b4 

Sangfroid.

13...Rac8 14.Nb5 Qh5 

White's position might look resignable, but he now actually has the advantage!

As F. Scott Fitzgerald did not say, "Grandmasters, they are different from you and me."

To which Ernest Hemmingway did not respond "Yes, they have more Jerome pawns."  

15.Nd6+ Kf8 16.h3 bxc5 17.Nxb7 

Black was expecting - or hoping for - 17.bxc5 Qxc5+ 18.Kh1 Nf2+ 19.Rxf2 Qxf2. 

17... cxb4 18.hxg4 Nxg4 

White has gone ahead in material, but his King still is under great pressure. There is a solution: Attack!

19.Qd6+ Kg8 20.f5 

Uncovering the Queen's protection of the h2 square.

20...Rc6 21.Qd5+ Kf8 22.Bf4 Rh6 

Attacking until the end, and offering the opportunity for the unfortunate blunder 23.Bxh6? Qh2#. However, White has things well in hand.

23.Bd6+ Ke8 24.Rae1+ Re6 25.Rxe6+ Kf7 26.Rh6+ Ke8 27.Re1+ Ne5 28.Rxe5 checkmate

Beautiful.

Jerome Gambit: Keep Calm

 

In 1939 the British Government created a steadying poster, encouraging citizens, in light of the upcoming war, to avoid panic and keep about their necessary activities.

Fair enough.

I have just learned of a modern variation

Available on sticker, poster, T-shirt, or many other items.

Many other openings are available.

(I am not sure how to tell my friend Dan that there does not appear to be a Stafford Gambit poster. 😢)

Jerome Gambit: GMHikaruOnTwitch; Well, of course...

Grandmasters do not always choose the "best" move in every position in their games, but they consistently find "very good" moves, and that is usually plenty enough for them to win their games against weaker opponents.

The following Jerome Gambit is a good example. It is not so much a smash/bang game as it is a business-like one where, when Black resigns, one likely thinks, Well, of course.

It is intersting that here, and for several subsequent moves, Stockfish 13 (which often does not appear to have a "feel" for the Jerome Gambit) prefers 15...h5, followed by a Rook lift ...Rh8-h6-g6.

The text allows White to create a protected passed pawn which factors into his winning chances thereafter.

With a glance at the endgame.

He could also have tripled on the f-file with 25.Qf2. I recall watching GM Nakamura comment during one of his 3 0 blitz games when he made a comment to the effect that tripling heavy pieces on a file always won. A bit of hyperbole, but solid wisdom. 

25...Kg7 26.h4 h6 27.Qc2 Nf8 28.R1f5 

The triple was still there with 28.Qf2, but White had other ideas. 

28...gxh4 29.Qf2 Re7

White applies pressure until the position cracks.

 30.Qxh4 Ng6 31.Qh5 Qe8 32.Rd6 Rf8

White's "Jerome pawns" are too much to deal with.

Jerome Gambit: More GMHikaruOnTwitch

In the following 3 0 blitz Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, it is interesting to see Grandmaster Hikaru Nakamura (see "Jerome Gambit: GM Hikaru Nakamura Again") take on a complicated line (that I really don't have a fix for, yet). That's the way it goes with the Jerome - sometimes you don't always need a "fix", you just need to outplay your opponent in a line that you are more familiar with - while the clocks are ticking.

The relaxed 11...Bf8 only appears once in The Database, but is certainly playable, as in BoomBoomTNT - YT-123456789010chess, Chess.com, 2020 (1-0, 21).
