Jerome Gambit: His Trap Was Part of My Trap

The following game again brings up a topic of concern

I have previously mentioned FIDE Master Dennis Monokroussos' thoughtful website, The Chess Mind, and his down-to-earth query, Is there even a single trap for Black to fall into in the Jerome Gambit?
My response has been

With due respect to Dennis, at the club level the entire Jerome Gambit can be considered a "trap" - especially if we consider psychological aspects. Black must pay attention, even as he treasures his advantages, or they will evaporate. 

My recently-completed game against AndrewLLL, in the third round of the "Italian Game Battlefield" tournament at Chess.com, is an example of the defender setting a nefarious trap, only to discover that his trap was part of my trap...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

The Italian Four Knights Jerome Gambit. The Database does not contain any games by Alonzo Wheeler Jerome with this line. I have played the line 60 times, scoring 74%.

 5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6

8.dxe5 Bxe5 

There is definitely something strange about this opening line of play - at least as far as I am concerned.

I recently posted a game where I now played 9.f4 -  perrypawnpusher - joseluizlopez, blitz, FICS, 2012 (0-1, 55) - that I had somehow overlooked posting 8 years ago.

In preparing for this post, I noticed that I had also not posted perrypawnpusher - lixuanxuan, blitz, FICS, 2014 (1-0, 22), where I explored 9.Bg5. I will fix that oversight soon. (The Database has 12 games with the move with White scoring 42%)

9.Ne2

After the suffering at the hands of joseluizlopez (see "Jerome Gambit: Another Historical 'Oversight' "), I made a note to try something that would keep my pawn structure intact. Little did I realize how odd the pawns would become.

9...c6 10.f4 Bc7 11.e5 Nd5 12.O-O Re8 

Black begins to castle-by-hand and is better, having a piece for a pawn.

White focuses on Blacks backward d-pawn, that blocks the light-squared Bishop, which, in turn, hems in the Rook. It is not enough compensation, but it is something to work on.

13.c4 Ne7 14.c5 b6 15.b4 a5 

My pawns are trying to gang up on the enemy d-pawn. If I only had an extra move, I could put my Bishop on b2, and then play a2-a3, with the ability to keep my pawn chain intact. Of course, I can't play 16.a3 directly, as it would fall to the simple 16...axb4. I decided to develop my Bishop and hope for the best.

16.Bb2 axb4 17.Qd4 

The attacking battery along the a1-h8 diagonal has potential. It will take a little cooperation to become dangerous, but it's not chopped liver.

In the meantime, the Queen threatens to capture the pawn at b4.

She also threatens to blunder, which Black notices quickly.

17...bxc5 

Guarding the pawn at b5, and offering the one at c5, instead. Of course, 18.Qxc5? would now be punished by 18...Bb6, pinning and winning the Queen. 

Black had stronger defensive ideas available - after the game, Komodo 10 recommended the consistent 17...Kg8, completing castling and maintaining the advantage - but I suspect that the "Negative halo effect" took hold of AndrewLLL at this point, and he figured, "If this guy is dumb enough to play the Jerome Gambit, he's probably dumb enough to hang his Queen". So he set his trap.

18.e6+ 

Black resigned

I had not worked out the attack completely, but it is clear that Black must now play 18...Kxe6, when, after 19.f5+ Nxf5 20.Qe4+ Kd6 21.Rad1+, the end would be near. After 21...Nd4, the exchange sacrifice is easy to find (the time limit for this game was 3 days per move), and, with 22.Rxd4+ cxd4 23.Qxd4+ Ke6 Black's King will not be long for the world.

Jerome Gambit: The Smallest Piece

Gerald Abrahams wrote in The Chess Mind that the smallest piece of a chess game was not a move, but an idea.

Bullet chess - in this case, a time limit of one minute with no increment - is all about looking at a position and getting an idea - quickly. The more you think on any one move, the less time you will have, on average, for every other move.

The Jerome Gambit is a wonderful playground for such a situation, as the following game by Angel Camiña shows.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 Qe7 

It's time for White to go to work.

9.O-O d6 10.f4 Nc6 11.Qc4+ Be6 12.Qe2 Rhe8 13.e5 dxe5 14.fxe5 Kg8 

Black castles-by-hand, safeguarding his King, but overlooking 14...Qc5+ which would have allowed him to capture the offending pawn on the next move. With only a second or two of time for each move, a player misses things - that's part of the excitment of bullet.

15.exf6 gxf6 16.Qf2 Rf8 17.Qg3+ Kh8 18.Bf4 Rg8 19.Qf2 Ne5

20.Rae1 Ng4 21.Qd4 Rad8 22.Qe4 f5 

A slip. Curiously, the right move was again 13...Qc5+.

23.Qxe6 Qxe6 24.Rxe6 

White is now a piece up, but the clock is making its demand: move, move, move...

Yes, The Jerome Gambit Is Playable (Part 2)

[continued from previous post]

Morin, Louis (1900) - Guipi Bopala, Prince Eric (1900)
Quebec Open, Quebec, 2018
40 moves / 90 minutes, then 30 minutes

So far, we have seen a few surprises. First, White played the Jerome Gambit in a serious over-the-board tournament. Second, Black, a youngster, has been holding his own - until a bit of a surprising (second-and-a-half?), if "scientific", return of the sacrificed material.

As the game progresses, I am reminded of some points made by Dennis Monokroussos, of the chess blog The Chess Mind, in a review of Hannes Langrock's The French Defense: The Solid Rubinstein Variation (2014). The perspective can be helpful in understanding "slow" Jerome Gambits.

A couple of practical drawbacks for [those playing the variation]: if you win, it’s going to take you at least 40 moves and possibly longer. That’s not so bad if you’re playing in a civilized tournament, but here in the U.S. at least you might be playing two full-length games in one day. If you’re young and full of energy then go for it (though if you’re young and full of energy you should play sharp openings instead!), but otherwise it may be a dubious tournament strategy. It’s also not very satisfactory if you’re in a must-win situation, unless you’re a big believer in your technical abilities or your opponent’s technical shortcomings... 

To his credit, he acknowledges early on some of the criticisms readers might offer; indeed, he relates asking the very strong German grandmaster Georg Meier if he isn’t concerned about the drawish tendencies of this line. Meier’s reply was that he has been able to win many kinds of endgames with it. And that’s the key: you have to have good technique and be willing to grind out points over the long haul. Meier is young and a great technician who is able to defeat lesser lights with remarkable regularity in this opening. Our mileage may vary, but by learning the types of endings that can arise via this opening we can replicate some of his successes in our own games. 

Now: back to our game.

34.Nd4 Rb7 35.Rfe1 Rxe1 36.Rxe1 Kf7 37.Re6 Be7

Perhaps the Bishop would be better placed at f6.

38.Nc6

Louis points out that, in time trouble, he missed the winning move, 38.f5! It looks like Black must avoid taking the pawn, as 38...gxf5 39.Nxf5+ leads to the fall of Black's d-pawn. On the other hand, after 38...g5, White's Rook can go after the h-pawn, i.e. 39.Rh6 g4+ (isolating White's f-pawn) 40.Kg2. Then, the computers like 40...a4 41.Rxh6 axb3 42.axb3 when things are still pretty complicated, but White has that extra pawn.

The computers also recommend 38.g4!?, which seems counter-intuitive, opening lines for the enemy Bishop, but, after 38...hxg4+ 39.Kxg4 it becomes clear that Black's minor piece is stuck in place, and 39...Rc7 might be the best chance, pursuing activity, even at the cost of a pawn after 40.Nxb5.

Remember, though: time trouble had reared it's fearsome head. Plus: even after the text move, White is better. And: the endgame is a difficult one.

38...a4 39.b4

Continuing to cramp the enemy Bishop, although 39.bxa4 bxa4 40.g4!? might have been playable, similar to the previous note. 

39...Rc7 40.f5 gxf5 

The first time control has been reached, and White's well-posted Knight dominates Black's troubled Bishop. The extra pawn means nothing. The game is even. (It is important to remember that in difficult situations, "even" does not equal "drawn".)

41.Rh6 Bf6

The Bishop can breathe! Also, the move limits the actions of White's Rook.

42.Rh7+ Bg7 43.Rxh5 Kg6 

44.Rh4

Possibly better was 44.g4!?. taking the chance to liquidate the Kingside pawns and preparing to hang on for the draw. Of course that's easy for me to say, as I was not playing the game.

44...Bf6 45.Rf4 Rh7+ 46.Kg2 Kg5 47.Rf3 Be5 48.Re3 f4

49.gxf4+

Reasonable, but it should allow Black's King to creep closer. Tougher was 49.Re1!? keeping it all in balance.

49...Bxf4

Keeping it even. Dizzying. Tick tock!

50.Rh3

According to the computers, this is the losing move, but how would I know? It makes perfect sense to me to exchange off the major pieces, but apparently this allows Black's King greater activity. On the other hand, 50.Re8!?, which supposedly leads to the half point after mad complications, would require incredible vision.

50...Rxh3 51.Kxh3 Kf5 

The problem is that while White can trade pawn-for-pawn, Black's King gets into the action, while White's is left out.

52.Nd4+ Ke5 53.Nxb5 Bd2 54.Na7 

Black has the game in hand. Impressive.

54...Kxd5 55.b5 Kc5 56.Kg2 Bb4 57.Kf3 Kb6 58.Nc8+ Kxb5 59.Ke4 Bc5 60.Ne7 Kb4 61.Kd3 Ka3 62.Kc2 Kxa2 63.Nd5
Ka3 64.Kc3 Bf2 65.Nf4 Bg3 66.Kc2 White resigned

Hats off to young Prince Eric Guipi Bopala, for playing such a fine game!

Jerome Gambit: The Whole Line Is A Trap

I have mentioned before National and FIDE Master Dennis Monokroussos' thoughtful website, The Chess Mind, where he once asked "Is there even a single trap for Black to fall into in the Jerome Gambit?"

With due respect to Dennis, at the club level the entire Jerome Gambit can be considered a "trap" - especially if we consider psychological aspects. Black must pay attention, even as he treasures his advantages, or they will evaporate.

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 Be6

Or 8...Nf6. See "Jerome Gambit: Tactic Fatigue" for a discussion.

9.f4 Nc6 10.Qa4 Nf6 

Black is doing well. He has attended to his development, and can protect his King in short order.

White, on the other hand, has to continue to find ways to sow disorder.

11.f5 Bd7 12.Qb3+ Ke7

I am not sure about this. Perhaps the King should go to f8.

13.Nc3 Re8 14.Nd5+ Nxd5

Of course, Black should have moved his King away, instead, with 14...Kf8, but it's no big deal, right?

15.exd5 Ne5

Suddenly Black's King feels a draft along the e-file, and so he blocks it off with his Knight. Sadly, to keep the position about level (White would have an edge) he needed to give up his extra piece with 15...Nd4 16.Qe3+ Kf8 17.Qxd4).

Now, danger comes from another direction. 

16.Bg5+ Black resigned

Jerome Gambit - Lost and Found

Last year, when John Watson and Eric Schiller's Taming Wild Chess Openings came out (New In Chess, 2015), I expressed disappointment on this blog that the Jerome Gambit did not appear to the authors to fit their sorting of A) Good B) Bad and C) Ugly chess openings and defenses. (Especially the "Bad" and the "Ugly".)

I am a bit behind in reading Dennis Monokroussos' "The Chess Mind" blog, and I just discovered - in Dennis' past review of Taming Wild Chess Openings, that the Jerome Gambit actually does appear.

My mistake. I had looked in the book's "Contents" without success. I had checked out the "Index of Moves and Variation Names" without discovering either the Italian Game, the Giuoco Piano - or the Jerome Gambit. Ditto the "Opening Index".

Ah, but Dennis pointed out - the Jerome is covered in the "Evans Gambit: Lasker Defense (C52)" chapter!

4.Bxf7+? Kxf7 5.Nxe5+ is the Jerome Gambit, which, however, is refuted by 5...Nxe5 6.Qh5+ (6.d4 Qh4! 7.0-0 Nf6 8.dxc5 Qxe4) 6...Kf8, or here 6...g6 7.Qxe5 Qe7, winning.

Regular readers are no doubt familiar with the "pie-in-the-face" (6...Qh4), Jerome (6...Kf8) and Whistler (7...Qe7) defenses.

My apologies to John and Eric, and my thanks to Dennis.

Abrahams Jerome Gambit: I Don't Understand

?!?!

Continuing my puzzlement from the previous column, I present a game that is entertaining - if gruesome for White. I found it on the Chess with DAO site. The game features the Abrahams Jerome Gambit, and, well, it should give you the feeling that something is missing - or was missed...

The game was presented on the site without the names of the players (although one is likely Joerg Dao), the location where it was played, or the date. The sub head "quick thing for hot kids?" (huh?) suggests that one of the players might be a student.

The notes to the move are all from the site, except my two comments in red.

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 

I have not found any games with this line that were played by Alonzo Wheeler Jerome, but at least one author - Gerald Abrahams, in The Chess Mind (1951) - has referred to it as the Jerome Gambit, so I have attached his name to the opening.- Rick

3...Kxf7 4.Qh5+ Ke6 5.Qg4+ Kd6 6.Qxg7 Ne7

now is there such a thing as a quickie? Where you offer a full piece in this, and get the K running and out ? Lets see. Its called Jerome Gambit, and mostly experts say, it is not playable.....

7.Qh6+ Ng6 8.d3 Qf6 9.f3 c6 10.Bg5 Qf7 11.f4 Qe6 12.fxe5+ Nxe5 

white is down one piece, but has 2 pawns more. And there is no such thing, as to hunt the black K somewhere...

13.Qg7 Rg8 14.Qxh7 Rxg5

another piece for a pawn ...

15.g3 Bxg1 16.Rxg1 Nf3+ 17.Kf2 Nxg1

3 vs. 5 pieces, no real chances any more. So lets finish in style.

18.Kxg1 b5 19.Nd2 Ba6 20.Nf3 Rg6 21.e5+ Kc7 22.Nd4 Qe8 23.e6 Rf6 24.exd7 Nxd7

black defense still solid, which is the basis of all that.

25.g4 Qe3+ 26.Kh1 Qxd4

- 2 vs. 5 pieces ...

27.Re1 Raf8 28.g5 Qd5+ 29.Kg1 Qxg5+ 30.Kh1 Rf1+ 31.Rxf1 Rxf1 checkmate 

yupp !! A löesson ? Maybe.

Maybe. But a lesson for who? Go back to diagram #2 and give it close look, if you haven't already. - Rick
