Jerome Gambit: A Recent Day in the Life

The following game is another one of those "day in the life" kind of things, as there are opening issues, middle game issues, endgame issues, time error issues... And yet, somehow, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) player comes out ahead again.

Does he play the Jerome because he is lucky, or is he lucky because he plays the Jerome?

9...b6 10.Qc3 Bb7 11.Qf3 Rf8 12.Qg4 d5 

Black's development is strong, keeping White's Queen over-worked (a basic critique of the Jerome Gambit is Her Majesty's wandering). His King is still in the center, however - and anything can happen in a 3-minute game.

White needs to be ready to make that "anything" happen.

13.O-O dxe4 14.Nc3 Qxd4 15.Be3 Qf6 16.Rad1 Rd8 17.Nb5 Kf7 18.Bg5 

White has sacrificed a couple more pawns, and his pieces are swarming, just as Black tries to castle-by-hand. What would be more natural than to offer to exchange Queens, to relieve the pressure? So Black errs...

18...Qf5 19.Qxf5+ Nxf5 20.Bxd8 Kg8 

Black's King is now safe, but he is down the exchange. He is not troubled, and pursues active play.

21.Bg5 h6 22.Bd8 e3 

Scary, especially if time is running short. Komodo 10 has other preferences, but this is a good "make my opponent think" move when the clock limits how deep analysis can go. 

23.Bxc7 

White could have captured the pawn with 23.fxe3, as the fork of the Rooks is an illusion - 23...Nxe3 24.Rxf8+ exchanges off one of the targets.

The game remains messy.

23...e2 24.Bd6 Nxd6 25.Nxd6 Ba6 26.c4 exf1=Q+ 27.Rxf1 Rf6 28.Ne4 Re6 

Things have changed. We are back to White having 2 pawns for a piece. In master vs master games, the advantage is often with the side with the extra piece, but in club games the pawns often give chances - although, in this case, with one extra pawn on the Kingside and one on the Queenside, there is a lot of work ahead.

29.Re1 Rc6 30.b3 Ne5 31.f4 Nd3 32.Rd1 

Offering a pawn for active Rook play, but Black is not interested - he prefers to trap his Knight (time trouble, no doubt).

32...Nb2 33.Rd7 

Instead, 33.Rd2 would trap the Knight, forcing 33...Nxc4 34.bxc4 Rxc4.

 33...Bc8 34.Rd8+ Kh7 35.Re8 

Still possible was 35.Rd2.

35...Rg6

A slip - followed by one by White - but the time pressure was too much.

36.Re7 Bh3 37.g3 Nd3 38.f5 Re6 39.Nf6+ 

Marvellous. Actually, any move wins, because here White won on time. 

Jerome Gambit: A Certain Amount of Bravery

 Playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) requires a certain amount of bravery. White sacrifices a couple of pieces for an attack, and this may lead to an overwhelming game - or a difficult loss. In the meantime, Black can defend quietly and stubbornly, or wildly - or he can offer to return some of the sacrificed material, after he has poisoned it.  

The following game is a good example of White going into complications that best requires previous study. However, the time control for the game is 1 minute, no increment, and in such an environment players can take risks knowing that attempts at refutation will cost the opponent too much time, or a shortage of time will keep the opponent from analyzing deeply. It's a risky strategy, but so is playing the Jerome Gambit.

And, what if Black knows the proper defense and counter attack? Well, then, it is best that he remember it accurately, or it will all be for naught...

Blackburne's, it is. (Whistler  played 7...Qe7.)

8.Qxh8 Qh4

 This was Henry Joseph Blackburne's idea, and he eventually produced the most well known Jerome Gambit game, Amateur - Blackburne, London, 1884, a crushing, sacrificial win for Black. Further play and analysis, however, showed that White had at least a draw, if not an advantage, amidst the complications. (The Database, for example, has 277 game examples, with White scoring 55%.)

Recent games have shown Black varying from Blackburne's plan, to their misfortune

9.O-O 

As I have posted, before, about a main alternative 

Munoz and Munoz, in their notes to Amateur - Blackburne, London, 1885, in the Brooklyn Chess Chronicle, suggested "He should have attempted to free his pieces by P to Q4 [9.d4] before castling." 

The move 9.d4 received a good look in "Updating the Jerome Gambit (Part 1)", including references to L. Elliot Fletcher’s energetic Gambit’s Accepted (1954), an internet article on Amateur - Blackburne (at www.superajedrez.com) by Brazil's Hindemburg Melao, and some musings and analysis from Bruce Pandolfini, in his 1989 Chess Openings: Traps & Zaps !

9...Nf6 10.Nc3 

The Knight looks like it is heading to d5, to hit the enemy Knight and secure the release of his Queen.

Here, though, it is useful to know the recommended 10.Qd8 Bb6 11.e5 dxe5 12.Qd3, and Her Majesty has escaped, with a slight advantage.

10...Ng4

The proper way to bring the  pain.

11.h3 

Now, how did that Blackburne game go? Did he capture with the Bishop or the Knight?

11...Nxf2 

Bummer. After 11...Bxf2+ 12.Kh1 Bf5, instead, White would lose his Queen.

Talk about complications. White now has the rescue move 12.e5, when 12...dxe5 13.Qxe5 would not only free his Queen, it would allow White to force a draw by repetition, checking the enemy King - unless Black answered with 13...Bf5, when Black would be able to split the point after 14.Qxc5 Nxh3+! and he can repeat the position with checks. Of course, after 12.e5 Bf5 13.Qf6+ Qxf6 14.exf6 would lead to an even game, although Stockfish 11 suggests that White may have an edge, unless Black tries 14...Nxh3+ 15.Kh2 Nf2+...

But, wait! White has another, better move.

12.d4 

Ah, yes. (See the note to White's 9th move.)

What exactly can Black do, now?

For starters, he has the delightful 12...Bf5, which puts a third and fourth piece en prise, and almost works, except for 13.Rxf2, when it turns out that White can afford to give up his Queen: 13...Rxh8 14.dxc5 and White will gather in the Bishop at f5, as well, giving him a Rook and two pieces for the enemy Queen.

Instead, 12...Bxh3 looks equally Blackburnian, but 13.Bg5! is a complete answer.

The fortunes of the players has reversed, and White is now clearly better. 

12...Bxd4 

This allows the escape of White' Queen and the end of Black's tactical surprises. 

13.Qxd4 Kg8 14.Qxf2 Qe7 

Black is down a Rook and a Knight - and, soon, a King.

15.Bg5 Qe8 16.Bh6 Be6 17.Qf6 Bf7 18.Qg7 checkmate

That is quite a lot of Jerome Gambit, for 1 minute of play on each side. And, as they say, Fortune favors the bold.

Jerome Gambit: A Positive Influence

I had a nice exchange of emails with a Reader a while back, wrapped around a couple of interesting Jerome Gambit-ish games. It is nice to see the Jerome have a positive influence on players' games. I have added diagrams, and my responses are in Blue - Rick

As an ex England youth player who recently got back into chess, I was very happy to recently find and start trying the Jerome.

I played a game against a friend online, whilst not quite a traditional Jerome, I feel many of the tactical ideas are traditional and highlights the sharpness of such lines. We see similar positions arising if black does not play Nxe5 in the traditional line. Feel free of course to use it in any blog posts you wish if it is of interest to you.

Having been bested by jerome-esque ideas, my friend also took up the line and played a solid game himself

It seems fair to say that Jerome-style tactics left opponents kerfuzzled...

1.e4 e5 2.Nf3 Bc5 is known as the Busch-Gass Gambit, although it resembles a reversed Jerome Gambit, especially after 4...Bxf2+. I suppose that the bishop sacrifice in a 1-minute game was comparable to being awakened from a deep sleep by a fire alarm: What? Where? Why? Many opponents can "solve" the Jerome Gambit and its relatives, given enough time. In fast chess, there is often not enough time.

Nice checkmate in 9, by the way.

I think it was great that your friend was willing to give it a try in his own game. I have begun to call 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ a sort of "impatient Jerome Gambit", as White doesn't wait for ...Bc4 before sacrificing his bishop. [Black] was probably just settling into a comfortable and familiar Two Knights Defense when he was shaken by the sac. I had to smile when Black played 8...Ke6, avoiding the calamity 8...Kg8 9.Qd5#. Still, a checkmate in 14 is pretty nice, too.

Jerome Gambit: Which Tier? Unbreakable?

 

In a previous post, I mentioned that in a light-hearted YouTube video, GM Hikaru Nakamura and IM Levy Rozman assessed different chess openings and assigned them to different levels in a tier.

Oh, and GM Nakamura, in assembling an "Intermediate Opening Tier List", bypassed "Legendary", "Solid", "Legit", and "Maybe Not", to place the Jerome Gambit in "Tricks Only" - above "Garbage" because, as he said, "I don't think it loses by force".

It should not be surprising that their "Chess Opening Tier List for the Grandmaster Level" places the Jerome Gambit at the very bottom of the "Garbage" tier. Despite GM Nakamura's blitz win with the Jerome, against another grandmaster, the opening is too sketchy for top level play.

However, the "Beginners Chess Opening Tier List" (thank you for the tip, Yury Bukayev) is a whole different thing - as is the play of beginners, of course. Where to place the Jerome Gambit, amont "Legendary", "Unbreakable", "Legit", "Really, Bro", "Tricks Only" and "Garbage"?

As IM Rozman opined

This was not very good when grandmasters were involved, but at the beginner level... obviously there's Only Tricks if Black plays the right way, but, man... it might be a bottom tier "Legit" opening... I mean, it could be "Really, Bro", it could be because I feel like soon everybody is going to know about it.

GM Nakamura responded 

This is true. Once everybody knows about it, it won't be as good... as it has been. Like, I don't know, I really don't know where it goes... 'Cause for now it's really something not not not known. I think once people... actually get a chance to look at it and study it they will realize it loses by force. I think I'm going to put it... It's going to go fairly high. I think I am going to put it right near the top of Unbreakable for now. It's pretty good. Actually, it can't go below the Fried Liver. I put it in second in the Unbreakable tier. I think it ranks pretty highly, I do... Oh, you disagree, Levy?... I don't know. I don't think I can put it in Legendary. Um I think it has to go right near the top of Unbreakable though.

This discussion reminds me of an early blog post, "But - Is this stuff playable??", (where I reframed the question  as "Under what conditions might the Jerome Gambit be playable?") and "Yes, The Jerome Gambit is Playable".

Of course, every Jerome Gambit game these days is a debate about the playability of the opening, and many Readers have demonstrated that the answer is often, "Yes, indeed." 

Jerome Gambit: Carelessness

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a chess opening with a list of refutations. Yet, it is growing in popularity among club players who not only like the exciting play it produces - they like the wins the Jerome brings as well.

How does someone lose to a refuted opening? There are many ways, but a major one is carelessness.

The following game is a good example of the defender's position being better, right up to the point where he is checkmated.

It is also a good example of White being constantly alert, making threats, and taking advantage of his opportunities.

Jerome Gambit: The Proper Medicine

After an interesting opening, White outplays his opponent in the following game. Solid strategy and effective tactics can cure even the most "refuted" of openings.

Emit79 - dimbenes1

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

The Semi-Italian Opening.

4.Bxf7+ 

This is one of what I call the "impatient Jerome Gambit", lines where White does not wait for ...Bc5 before sacrificing his Bishop. It gains in immediacy of surprise, but lacks a target on c5 that sometimes allows White to recover some material.

Both 4.0-0 Bc5 5.Bxf7+ and 4.Nc3 Bc5 5.Bxf7+ are referred to at the Semi-Italian Jerome Gambit.

Black has his heavy pieces in place, but White's attack arrives first.
