Jerome Gambit: Scotch Jerome Hybrid

The following game shows an interesting Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that could have arisen out of the Scotch Gambit move order (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5). Those who play that latter opening might enjoy the possibilities.

6.c3 Nf6

The solid 6...d6 was seen in Wall - Anonymous, lichess.com, 2016 (1-0, 23).

Taking the pawn with 6...dxc3 would be risky. There are 1,343 games with that move in The Database. White scores 67%. Stockfish 15 evaluates the position after 7.Qd5+ and 8.Qxc5 as being about a pawn better for White.

7.e5 Ne4 8.cxd4 Bb4+ 9.Nbd2 d5 10.O-O 

So far, Black has defended well and has the advantage.

He now plans to emulate White and castle - by hand. This is a common strategy when defending against the Jerome Gambit, but in this case there are special circumstances to consider.

10...Rf8 11.Nxe4 dxe4 12.Ng5+ Kg8 

All according to plan. 

As Bill shows, however, the more risky-looking 12...Kg6 was a better reply. 

13.Qb3+ Kh8 14.d5 

Kicking the Knight that protects the Bishop that is attacked by the Queen.

Note if 14.Nf7+ Black can simply sacrifice the exchange with 14...Rxf7 15.Qxf7 and then pick up a pawn with 15...Nxd4, remaining better. 

14...e3 

It is not clear what Black had in mind here.

He could have tried the routine 14...Nxe5, returning material for development, when 15.Qxb4 Nd3 16.Qxe4 Bf5 17.Qc4 would be equal, and would allow the interesting 17...b5!? 18.Qc6 (not 18.Qxb5 Nxc1 followed by 19...Qxg5) 17...Nxc1 18.Qxc1 Qxd5 with things remaining in balance.

15.Bxe3 Nxe5 16.Qxb4 a5 

Material is even. White's development is better.

Black decides to deflect the enemy Queen.

17.Qe4 Ng6 18.Ne6 Bxe6 19.dxe6 Qe7 

At first glance it looks like Black will be able to swing a Rook over to the e-file and then capture the pawn on e6 with hopes for an equal game. However, the "Jerome pawns" are not cooperative.

20.f4 Rae8 21.f5 Rf6 

Using the Queen and the Rook as blockaders for the pawns limits their effectiveness. How much so? Stockfish 15 now evaluates White as over a Queen better.

22.Bd4 

Ouch.

22...Nf8 23.Bxf6 Qxf6 24.Qxb7 Black resigned

Black is down the exchange and a couple of pawns and he still has to deal with those advanced pawns.

Jerome Gambit: Tactical Magic

The following game features a creative Queen sacrifice - not to break down the walls of the enemy's fortress, but to gain a tempo. It is quite a thing to watch, and finish of the game is equally entertaining.

Tactical magic.

Wall, Bill - Anonymous

internet, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 

6...Bxd4 7.Qxd4 Qf6 8.Nd2 Ne7 9.O-O Re8 10.Qc3 N7c6 

11.f4 Ng6 12.e5 Qf5 13.Qb3+ 

White wishes to interrupt Black's plan to castle-by-hand.

13...Kf8 14.Nf3 d6 15.Ng5 Nh8 16.h3 h6 

Skirmishes on the Kingside do not change the balance. Black is still better, with a piece for a pawn.

17.Bd2 Nd4 18.Qd5 Ne6 19.Ne4 Nf7 

Black's pieces shuffle themselves, the better to protect their King.

Once again, as White, Bill has slowly managed to bring about an exchange of roles. Black should be attacking.

20.g4 Qh7 21.f5 c6

It is interesting that Stockfish 13 suggests the return of the sacrificed material, with 21...Neg5 22.e6 Nxe6 23.fxe6 Bxe6. Things can then get tactically messy if White goes for one more pawn, i.e. 24.Qxb7 Rab8 25.Qc6 Bxg4 26.Qxc7 Bf5 27.Ng3 Qg6 28.Kh2 Be6 29.Ne2 Rbc8 30.Nf4 Rxc7 31.Nxg6+ Kg8 32.c3 Kh7 33.Nf4 Bc4 34.Rf2 Ng5 and Black would still have an edge.

22.Qc4 

Stockfish 13, which frequently sees White as worse in any Jerome Gambit - and, therefore, often suggests long lines ending in a draw by repetition - of course preferred 22.Qa5 Neg5 23.Nxd6 Nxd6 24.exd6 b6 25.Qc3 Bd7 26.Rae1 Ne4 27.Qd3 Nf6 28.Re7 Rxe7 29.dxe7+ Kxe7 30.Bc3 Kf8 31.Qd6+ Kg8 32.Re1 Re8 33.Rxe8+ Bxe8 34.Qd8 Kf7 35.Qc7+ Kg8 36.Qb8 etc. Cute.

When you get to the end of this game, I hope you appreciate the fact that White was played by a human. Especially since Black now believes he has caught White in a blunder.

22...d5 

Forking Queen and Knight.

23.fxe6 

Wonderful! White has a draw in hand, and more if Black becomes too excited.

23...dxc4 24.Bb4+ Re7 

If the King moves instead, White has a checkmate in 10 moves.

25.Rxf7+ Kg8 

Because 25...Ke8 will result in checkmate.

26.Nf6+ gxf6 

Again, forced to avoid a short checkmate.

27.Bxe7 

White is down a Queen for a Rook. Can he keep things going?

27...Qxf7  

I think that this move was deeply thought out - just not deeply enough. Black imagines reducing the position to an ending of Bishops-of-opposite-colors (despite the Rooks being on the board) where he can take refuge in a draw.

He has the right idea, with best play the game is drawn, but he would have been closer to that goal with 27...Qe4, when his King would be trapped in a sort of "windmill" that would have produced a repetion of position: 28.Rf8+ Kh7 29.Rf7+ Kg6 30.Rxf6+ Kh7 (not 30...Kg5, as 31.Raf1 will produce situations where Black will lose his Queen to a discovered check) 31.Rf7+, etc.

28.exf7+ Kxf7 29.Bxf6 Be6 

30.Rf1 Kg6 31.Be7 Bd5 32.Rf6+ Kg7 33.Rd6 Re8 34.Bf6+ Kg8 

35.Rd7

This move should have given Black pause. The "correct" way to pursue a draw is 35.Rd8, exchanging Rooks.

 35...Rb8 36.Kf2 

The King will lend an extra hand.

36...Bf7 37.Ke3 c5 38.Ke4 Kf8 39.Kf5 a5 40.e6 Bg8 41.Rd8+ 

Instead of celebrating here, Black resigned.

The sad truth is that even after 41...Rxd8 42.Bxd8, White's King is well-placed to capture the pawn on h6, and that will leave him with too many pawns for the opposite color Bishop ending.

But White had no intention  of entering that line, planning 41...Rxd8 42.e7+! when checkmate arrives quickly after the promotion, 42...Kf7 43.exd8/Q. 

Very, very nice.

Jerome Gambit: Looking Deeper

Jerome Gambit games played at bullet speed - one minute, no increment - are fun to watch or play over. They are a testament to those players who have a deep understanding of the needs of difficult positions, and who can see tactics in an eyeblink.

At the same time, I enjoy games played at a slower speed. They often produce solutions to different opening problems - or create new issues. The following game is a challenging example.

Wall, Bill - NN
Florida, 2019

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

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4

This is what I have called a "pie in the face" variation, one of the toughest challenges to the 6.d4 lines in the Jerome Gambit. It first appeared in Sorensen - X, Denmark, 1888 (1-0, 27).

While "objectively" strong for Black, 6...Qh4 leads to complicated play for both sides. This is illustrated by The Database - there are 2,018 games with the position after White's 6th move, with White scoring 55%. However, there are only 285 games (14%) with 6...Qh4, and in them White scores an improved 67%. These results, in part, may reflect White's familiarity with the opening and a taste for tactics that led him to play the Jerome Gambit in the first place.

Of note, Bill has faced 6...Qh4 38 times, and scored 88%. That may seem daunting for the defender, but Bill has scored 93% in all of his 6.d4 games, so 6...Qh4 has been one of the more relatively effective defenses against him.

7.O-O Ng4

Black is happy to play for checkmate.

8.h3 Bd6

Cold-blooded: White can not now take the Knight with his pawn, as that would lead to checkmate; while taking with the Queen would lead to an exchange of Queens, and the typical piece-for-two-pawns advantage (not to mention the end of White's attack).

9.e5 Nxe5

Giving the piece back, after all, for two pawns; this may have been part of Black's plan. Stockfish 10 suggests, instead, 9...Be7 10.hxg4 d6, which seems to clash with Black's "scientific" approach. However, the Kings now reverse roles, as White's becomes safer, while Black's is more at risk. 

10.dxe5 Bxe5 11.Qd5+ Kf6

Black has to try to hold on to his Bishop. Unsuccessful was 11...Kf8 seen in Wall,Bill - Mecnieri, PlayChess.com, 2018 (1-0, 23).

12.Re1

Bill was 5 - 0 with this move previously, and wins again, this game. Next time, though, he might try a suggestion of Stockfish 10, 12.Nd2 (intending Nf3). Why? Follow along in the notes.

12...d6 13.Rxe5

Nice.

A year ago, Bill's choice of moves was not as strong, although he still won: 13.Re4 Qh5 14.f4 Ne7 15.fxe5+ dxe5 16.Qd3 Bf5 17.Nc3 Rad8 18.Qf1 Rhf8 19.g4 Qg6 20.Kh2 Ke6 21.gxf5+ Rxf5 22.Qc4+ Nd5 23.Rg4 Qf7 24.Ne4 h6 25.Bd2 Ke7 26.Rag1 g5 27.Qc5+ Ke8 28.Qxa7 Nf4 29.Qxb7 Ne2 30.Qb5+ Black resigned, Wall,Bill -Guest3836682, PlayChess.com, 2018.

13...dxe5 14.Qd8+ Ne7 15.Qxh8

Three years ago, an opponent now tried 15...Qe4, and ran into trouble and lost, in Wall,Bill - Anonymous, lichess.org, 2016 (1-0, 25).

The same year, another defender tried 15...Kf7, but quickly lost his way, and, then, the game, in Wall, Bill - NN, lichess.org, 2016, (1-0, 37). He had a resource, but he was not the only one to overlook it.

Sami, at lichess.org, had the right idea against Bill, earlier this year, and uncorked 15...Bxh3!?, a Rook sacrifice which brings to mind Blackburne's famous play back in 1884. Fortunately for Bill, the game continued 16.Qxa8 Bc8? and Black staggered on a Rook down, for a while, eventually being checkmated.

The proper followup was 16...Bxg2!?, when 17.Kxg2 would allow Black to draw by repetition, starting with 17...Qg4+. Okay, a draw is not as good as Blackburne's scintillating win with Black, but it still would have been a game to brag about at the club.

Likewise, after 15...Kf7, by NN, as mentioned above, if White were to play 16.Nd2 or 16.Qd8, his only two moves to avoid a losing position, the proper (drawing) response for Black would be 16...Bxh3.

Of course, all of this is based on the idea that Black - having been gifted with two pieces - would suddenly pursue a drawing line. Psychologically, that might be very difficult.

15...Qh5 

Black treats the position casually, threatening a check at d1 and a possible fork of King and Bishop.

16.Qf8+

This is a novelty, according to The Database.

Previously, Bill had met Black's threat with 16.Nc3 in Wall,Bill - Itboss, lichess.org, 2016 (1-0, 20).

16...Ke6 17.Nc3 c6

Black passes up the safer 17...Qf7, with the hope of exchanging Queens.

18.Ne4

At first, this move doesn't look like much, but it is crushing. It is horribly ironic that the only line, now, that doesn't lead to checkmate, is the surrender of that Rook: 18...Bd7 19.Qxa8; but, of course, Black would still be lost.

18...b6 19.Bg5 Kd5 20.Qd8+ Kxe4 21.Qd3 checkmate

Brutal.

Jerome Gambit: Game of the Year?

Of course, when it comes to selecting Jerome Gambit games, it is always pleasant to find one that shows a powerful attack. In the following game, Black is quite willing to mix it up with his opponent. White, however, has more sacrifices in store, and the board quickly erupts in flames. Certainly this battle bids for Jerome Gambit game of the year!

Wall, Bill - Bojovic, Dejan
PlayChess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

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

Protecting the Knight, while establishing a veiled threat against the e-pawn and the King behind it.

8.O-O Nf6

An improvement over 8...c5 9.Qd5+ Qe6 10.Qxc5 Ne7 11.f4 d6 12.fxe5+ Black resigned, Wall,B - Anonymous, lichess.org, 2016.

9.Nc3 Nc6 

Probably better than 9...c6 10.f4 Ng6 11.e5 Ng4 12.h3 Nh6 13.f5 Nh4 14.f6 gxf6 15.exf6 Nf3+ 16.Rxf3 Qe6 17.Bxh6 Rg8 18.Qd3 d5 19.Qxh7+ Ke8 20.f7+ Black resigned, Wall,B - Guest2327120, PlayChess.com, 2014. 

10.Qd3 Nb4 11.Qc4+ Kf8 

Black would have done better to complicate things with 11...d5 12.exd5 Nxc2. 

12.e5 Nh5 

Black's Knights do not impress.

Stockfish 8, which always seems to keep an eye out for the draw, recommends 12...Ne8 13.Qf4+ Kg8 14.Qc4+ Kf8 and repetition. I can't see Bill wanting to wrap things up so quickly - at the cost of surrendering a half point.

13.f4

Protecting the e-pawn and considering possible pawn advances. Also available was the fork of the two Knights, 13.Qg4.

13...Nxc2 

The Rook on a1 looks like a good target, but this adventure will not turn out well. 

14.Nd5 Qe6 15.Qxc7 

It is not easy to see that 15.f5 is playable, as after 15...Qc6 16.Qe4 Black would have 16...Nxa1. However, White would have complex but strong play after either 17.Bg5!? or 17.f6.

White's choice in the game is practical, and still offers the Rook sacrifice. Black would now do better to decline it with 15...Qxd5 16.Qxc2 d6 17.Be3 Qf7 18.Rad1 Bf5 although White would be at least even in a complicated position.

15...Nxa1 16.f5 

Bill's idea - offer more material!

16...Qxd5

The only move that avoids checkmate. Wow.

17.Qd8+ Kf7 18.e6+ dxe6 19.fxe6+ Kxe6 

20.Re1+ Qe5 21.Rxe5+ Kxe5 22.Qxh8 Nc2 23.Qe8+ Black resigned

For the moment Black has two Knights and a Rook for his Queen, but he is going to drop the piece on h5 right away. The placement of his King, and the agility of the enemy Queen guarantee that another piece, as well as a few pawns, will also disappear soon after.

Jerome Gambit: Beware the Calm After the Storm

The following game starts out with the wild Jerome Gambit, which is met by one of the wildest defenses available.

White does not deliver checkmate.

Black does not deliver checkmate.

The game becomes balanced and calm.

Then White checkmates.

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

This is Black's sharpest response to 6.d4. I have often called it a "pie-in-the-face variation".

7.O-O Ng4 8.h3 Bb6

Probably Black's best move. Bill has faced

Black is not too upset at having lost his Knight, as he plans to move the other one into the attack.

10.g5 Ng4 11.Qf3+ Ke8 12.Qh3 Qxh3 

Leading to a situation similar to what we recently saw in Wall, Bill - Guest709079, PlayChess.com, 2017 (1-0, 30) - Queens are exchanged, and Black's Knight is trapped. Quirky.

13.gxh3 Nxf2 14.Kxf2 Bxd4+ 15.Kg2 d6 

The game has reached a balance. Should either player be pleased with this? Black started out after a few moves with a "won" position, so he may not be happy. White threw a whole lot into a wild attack, so he may wish for more than a split point.

16.c3 Be5 17.Nd2 Bd7 18.Nf3 Bc6 19.Bd2 Bxe4 20.Rae1 Bc6 21.Bf4 Rf8 22.Bxe5 dxe5 23.Rxe5+ Kf7

Stockfish 8 slightly prefers 25.Rf2, keeping the game level. The Rook eventually gets there.

32...Rxh4+ 33.Kg3 Rff4 34.Rd2 Re4 

Looking to swap Rooks, and enjoy a guaranteed draw, while hoping to make something out of his extra Kingside pawn?

Black has overlooked something.

35.Rd8+ Black resigned

Jerome Gambit: More Pie, Please

The following game tells an often-shared tale: it is not enough to know the move that "refutes" a line, it is necessary to know the follow up. This is especially the case in a very sharp, double-edged opening like the Jerome Gambit.

Wall, Bill - PassCapture
lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4

Elsewhere I have referred to this a "pie-in-the-face" variation, and it is one that can come as a shock to the unprepared Jerome Gambiteer - but Bill Wall is hardly unprepared. He has had success against other lines in the 6.d4 variation, and is ready if someone wants to mix it up with the text.

7.O-O Ng4 8.h3 N8f6 

With this move (a novelty according to The Database) Black continues to pursue development over material, refusing to retreat.

Bill has faced other lines as well:

8...Bd6 9.e5 Bxe5 (9...Nxe5 10.dxe5 Bxe5 11.Qd5+ Kf6 12.Re1 d6 13.Rxe5 dxe5 14.Qd8+ Ne7 15.Qxh8 Qe4 [15...Kf7 16.Nd2 Ng6 17.Nf3 Qxf2+ 18.Kxf2 Nxh8 19.Nxe5+ Kf6 20.Nf3 Bf5 21.Be3 Ng6 22.g4 Be4 23.Bd4+ Ke6 24.Re1 Rf8 25.Rxe4+ Kd5 26.Ke3 c5 27.Bxg7 Rf7 28.c4+ Kd6 29.Be5+ Nxe5 30.Nxe5 Rf1 31.Nd3 Rh1 32.Nf4 Rh2 33.Re6+ Kc7 34.Re7+ Kb6 35.Rxh7 Rxb2 36.g5 Rxa2 37.g6 Black resigned, Wall,B - NN, lichess.org, 2016] 16.Qf8+ Ke6 17.Bg5 Qb4 18.Qxg7 Bd7 19.Qf6+ Kd5 20.Nc3+ Kc4 21.b3+ Kxc3 22.Qxe5+ Qd4 23.Bd2+ Kxd2 24.Qxd4+ Kxc2 25.Rd1 Black resigned, Wall,B - Anonymous, lichess.org, 2016) 10.dxe5 Nxe5 11.Qd5+ Kf6 12.f4 Ng6 13.Nc3 d6 14.Be3 Ke7 15.Rae1 Kd8 16.Nb5 Nf6 17.Qc4 Ne8 18.Bf2 Qf6 19.Bd4 Qh4 20.Rxe8+ Kxe8 21.Nxc7+ Kf8 22.f5 Ne5 23.f6 gxf6 24.Qd5 Kg7 25.Qxd6 Rg8 26.Rxf6 Qxf6 27.Bxe5 and won Sorensen,S - X, Denmark, 1888

9.dxc5 Nxe4

I would have expected the consistent 9...h5!? with attack still on Black's mind, although Stockfish 8 prefers 9...Ne5 10.f4 Nc6 and White's advantage is slight.
