Jerome Gambit: Despite

Despite the fact that the Jerome Gambit and its relatives are considered "refuted" openings, devotees continue to play the lines, with success.

The Database has almost 1,300 games by angelcamina, who scores 64% - all at bullet speed.

In the following game, he collects another point.

angelcamina - GGGOKHANSS

1 0 bullet, lichess.org, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Ke7 

"The only way to defeat a gambit is to accept it." - Steinitz

"I don't believe in psychology. I believe in good moves." - Fischer

"Capturing the Bishop is about a pawn better for Black; Declining the Bishop is about 3 pawns better for White" - Stockfish 16.1, if it could talk

5.Nxe5 

The text is about as strong as retreating the Bishop to c4 or b3 - or capturing the Knight: 5.Bxg8 Nxf3+ 6.Qxf3 d6 7.Bb3 Qe8 8.d4 exd4 9.Bg5+ Kd7 10.Qf5+ Kc6 11.Ba4+ b5 12.Qxb5 checkmate, angelcamina - Black_attac, 1 0 bullet, lichess.org, 2019 

5...d6 

Or, 5...Nf6 6.Bb3 d6 7.Nf3 Bg4 8.c3 Nxf3+ 9.gxf3 Bh5 10.d4 Kd7 11.Be3 c6 12.Nd2 Kc7 13.Qc2 Be7 14.O-O-O Rc8 15.Bf4 Kb8 16.e5 dxe5 17.dxe5 Nd5 18.Ne4 Ka8 19.Bg3 Bf7 20.Nd6 Bxd6 21.exd6 Qb6 22.c4 Nb4 23.Qf5 Bg6 24.Qg5 Rhe8 25.d7 Black resigned, angelcamina - BatuBey_22, 1 0 bullet, lichess.org, 2022 

6.Bxg8 dxe5 7.Bc4 

Or, retreating further, 7 Bb3 Ke8 8.O-O Be6 9.Bxe6 Nxe6 10.c3 Ng5 11.d4 Bd6 12.dxe5 Bxe5 13.Qxd8+ Rxd8 14.f4 Nxe4 15.fxe5 Ng5 16.Bxg5 Rd5 17.Bf4 Rd2 18.Nxd2 Black resigned, angelcamina - nicolasabra, lichess.org, 2019

7...Ke8 

This looks something like the position after move 3, with one less Knight for White and two fewer pawns for Black. Oh, and Black's King can no longer castle.

White now collects some material.

8.Qh5+ g6 9.Qxe5+ Kd7 10.Qxd4+ Ke8 11.Qxh8 

Down a Rook, a Knight, and 3 pawns, Black decides to continue playing. Perhaps he has an eye on the clock? It is a 1-minute game, after all.

11...Bg4 12.Qe5+ Be7 13.d3 c6 14.Bg5 Qd7 15.Bxe7 Qxe7 16.Qxe7+ Kxe7 

Did Henry David Thoreau play chess? In any event, his advice here was followed: Simplify, simplify simplify.

17.O-O Be6 18.Bxe6 Kxe6 19.Nc3 Rd8 20.f4 b5 21.Rae1 a5 

In short order, White now opens lines, creates a passed pawn, and always has his eyes on checkmate.

22.f5+ gxf5 23.exf5+ Kf6 24.Ne4+ Ke5 25.f6 Rf8 26.f7 Ke6 27.Ng5+ Kd7 28.Nxh7 Rxf7 29.Rxf7+ Kd6 30.Ng5 Black resigned

BSJG: Hunting the Uncooperative King

The Following Blackburn Shilling Jerome Gambit game features a King hunt, and a very uncooperative King.

White eventually corralled the monarch, but not without effort.

anilone - mohammadkhanbeyg

10 0 rapid, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburn Shilling Gambit.

4.Bxf7+ 

The Blackburn Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 

The King can also retreat with 5...Ke8, as in Nater - Rogers, Ballarat, 1975 (0-1, 46).

6.c3

This is the right idea, and it tempts Black to pursue material. 

6...Kxe5 

Of equal strength is 6...Nc6, e.g. 7.Qg4+ Kxe5 8.d4+ (8.Qf5+ Kd6 9.d4 Nce7? 10.Bf4+ Black resigned, anilone - butilicapetrica, lichess.org, 2024) 8...Kd6 9.e5+ Nxe5 10.dxe5+ Kxe5 11.Bg5 Nf6 12.Qf4+ Ke6 13.O-O d5 14.c4 c6 15.Nc3 Bd6 16.cxd5+ Kf7 17.Qf3 Rf8 18.dxc6 bxc6 19.Qxc6 Be6 20.Rad1 Ke7 21.Ne4 Qd7 22.Rxd6 Qxc6 23.Rxc6 h6 24.Bxf6+ gxf6 25.Re1 Kf7 26.Nd6+ Kg6 27.Rxe6 Rab8 28.b3 a5 29.Ne4 a4 30.Nxf6 axb3 31.Nd7+ Kg7 32.Rg6+ Kf7 33.axb3 Rfd8 34.Ne5+ Kf8 35.Rcf6+ Ke7 36.Rf7+ Ke8 37.Rg8 checkmate, anilone - fhat31, lichess.org, 2024. 

7.cxd4+ 

White has also experimented with 

7.Qh5+ Ke6 8.Qd5+ (8.cxd4 Nf6 9.Qd5+? White resigned, anilone - Togtamyrat, lichess.org, 2024) 8...Ke7 9.Qxd4 d6 10.d3 c5 11.Qe3 Kf7 12.O-O Be7 13.f4 h6 14.e5 d5 15.f5 Bg5 16.e6+ Kf6 17.Qf3 Bxc1 18.Rxc1 Qd6 19.d4 c4 20.Re1 Ke7 21.Re5 Qb6 22.Qg3 Qxb2 23.Qxg7+ Kd6 24.Re1 Qxa1 25.e7 Nxe7 26.Qxe7+ Kc6 27.Qc5+ Kd7 28.Re7+ Kd8 29.Qc7 Black resigned, anilone - PPNRegKal, lichess.org, 2024; and

7...Kxd4 

Taking the bait. In 212 games in The Database, White now scored 65%. 

Taking the e-pawn was no solution, either, e.g. 7...Kxe4 8.Qh5 Nf6 9.Qe5+ (9.d3+ Kxd4 10.Qb5+ Kxd4 11.Be3+ Ke4 12.Nc3 checkmate) Kd3 10.Qe3+ (10.O-O!?) Kc4 11.Na3+ (11.b3+ Kb5 12.Nc3+ Kb6 13.d5+ Bc5 14.Na4+ Ka6 15.Nxc5+ Kb5 16.a4+ Black resigned, anilone - STEAUA1980, lichess.org, 2024) 11...Kd5 12.Qe5+ Kc6 13.Qb5+ Kd6 14.O-O Ke7 15.Re1+ Kf7 16.Nc4 d6 17.Qd5+ Kg6 18.Ne5+ Kh5 19.Qf3+ Bg4 20.Nxg4 Nxg4 21.h3 Qh4 22.Qf5+ Qg5 23.hxg4+ Black resigned anilone - Sanmisongz. lichess.org. 2024. 

Giving Black an edge was 7...Ke6 8.d3 (or 8.d5+ Ke7 9.d4 d6 10.Bg5+ Nf6 11.e5 dxe5 12.dxe5 Kf7 13.O-O h6 14.Bxf6 gxf6 15.Qh5+ Kg7 16.e6 Qe7 17.Nc3 Rh7 18.f4 Kh8 19.f5 Bg7 20.Ne4 b6 21.Rad1 Bb7 22.d6 cxd6 23.Nxd6 Bc6 24.Nf7+ Kg8 25.Rd6 Rc8 26.Rfd1 Bf8 27.Qg6+ Rg7 28.Nxh6+ Kh8 29.Nf7+ Rxf7 30.exf7 Qe3+ 31.Kh1 Bxd6 32.Qxf6+ Kh7 33.Qxd6 Bxg2+ 34.Kxg2 Rc2+ 35.Kh1 Qf3+ 36.Kg1 Qf2+ 37.Kh1 Qg2 checkmate, anilone - lorountu, lichess.org, 2024) 8...Qf6 9.d5+ Kf7 10.O-O Bc5 11.Be3 d6 12.Nc3 Ne7 13.d4 Bb4 14.f4 Bxc3 15.bxc3 Rf8 16.e5 Qf5 17.c4 Kg8 18.e6 Bxe6 19.dxe6 Qxe6 20.Qd3 Nf5 21.Rae1 Nxe3 22.Rxe3 Qf5 23.Qxf5 Rxf5 24.Re7 Rf7 25.Rfe1 b6 26.g3 c5 27.d5 a6 28.R1e6 Rxe7 29.Rxe7 b5 30.Rd7 bxc4 31.Kf2 c3 32.Ke2 Rb8 33.Kd3 Rb2 34.Kxc3 Rxa2 35.Rxd6 Rxh2 36.Rxa6 Rg2 37.d6 Rxg3+ 38.Kc4 Kf7 39. f5 g6 40.

8.Qh5 

Cutting the enemy King off from returning to his home is a good idea, although it is not the best one. Instead, 8.Nc3 was seen in 13 games in The Database, with White scoring 72%.

Such an exposed King surely must get checkmated!

8...Nf6 9.Qg5 

Keeping the enemy far afield, and an improvement over 9.Qb5 c6 10.Qa4+ Ke5 11.d4+ Kxe4 12.Nc3+ Kf5 13.d5 Qe7+ 14.Be3 cxd5 15.O-O Kg6 16.Bd4 Qb4 17.Qc2+ Kf7 18.Bxf6 gxf6 19.Nxd5 Qc5 20.Qf5 Bg7 21.Rac1 Qa5 22.Rfe1 d6 23.Re7+ Kg8 24.Rxc8+ Rxc8 25.Qe6+ Black resigned, anilone - Wacwacnepo, lichess.org, 2023. 

9...d5 

This is an all-around useful move for the defender.

10.e5 Qe7 

Black pins the e-pawn, but this move neglects the safety of his King. Better was 10...Kc5 11.d4!? Kc6 12.O-O Be6 13.exf6 Qxf6 with continued equality.

11.Qe3+ Kc4 

12.Qc3+ 

Instead, 12.Na3+ would force the win of the enemy Queen with 12...Qxa3 13.bxa3, because 12...Kb4 would allow 13.Qc3+ Ka4 14.b3 checkmate.

12...Kb5 

The King keeps trying to escape. White could now try 13.a4+ Kb6 14.a5+ Ka6 15.O-O Ne8, but Black would have an edge. Frustrating!

13.Na3+ Ka6 

A slip - and a fatal one. Still good for Black was 13...Kb6 14.Qb3+ Qb4 15.Qxb4+ Bxb4 16.exf6 Bf5 17.O-O gxf6.

14.Qd3+ Kb6 15.Qb5 checkmate

Jerome Gambit: A Map

Experience with an opening line is like a map to help you along the way. 

In the following game, White shows that he has the proper directions.

angel_camina - StaleDustyBelly

1 1 bullet, Chess.com, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 

7.Qxe5 Bd6 

 Recently seen in "Not Poisoned But Tasty". 

In a bullet game, one grabs whatever tactic or threat is at hand. Unfortunaetly for Black, angelcamina has been in this position 14 times previously and knows that the Rook is not "poisoned".

One player has the map to this opening, the other does not.

8.Qxh8 Qg5 

I would not be surprised to learn that StaleDustyBelly has played the Blackburne Shilling Gambit, as in that counter-attacking defense ...Qg5 is a dynamic part of the opening. 

Alas, The Database has 37 games with 8...Qg5, and White scores  84%. 

9.Qxh7+ Ke8 10.O-O 

No need to be greedy, although 10.Qxg8+ Bf8 11.O-O was an alternate path. 

10...Nf6 11.Qh8+ Ke7 12.d4 

Threatening the Queen, as well as a fork at e5.

12...Qg4 

13.e5 b6 

Hoping against hope: if he can get his Bishop to b7, he can threaten both checkmate and the enemy Queen.

However, White now has a forced checkmate.

14.Qxf6+ Ke8 15.exd6 c6 16.Re1+ Black resigned

White will win Black's Queen after 16...Qe6, and then deliver checkmate the next move.

(Yes, yes, Readers, White also had 16.Qe7 checkmate. You win your way, angelcamina will win his.)

Jerome Gambit: Objective vs Subjective

The following game got me thinking about something I wrote in "Blackburne Shilling JeromeGambit: Objective and Subjective"

When putting together a Jerome Gambit repertoire, it is useful to have access to both "objective" evaluations - say, from a computer chess engine - and "subjective" evaluations - as from a collection of games that can tell you how successful a line has been. Often a move that is not "objectively" best may score very well in actual play. 

angelcamina - LechstergFelix3

1 0 bullet, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit. 

White has calmer and more sober responses in 4.0-0, 4.Nxd4, and 4.d3, but the Bishop sacrifice is more Jerome-ish.

To be fair, I have not found any games with Alonzo Wheeler Jerome playing this line. 

I also have not found any games with Joseph Henry Blackburne playing his "shilling gambit," either.

See "Jerome Gambit: Blackburne Shilling / Kostic Jerome Gambit (Parts 1 & 2)".

4...Kxf7 5.Nxe5+ Ke6 

An overview of angelcamina's games with the gambit can be found at "Jerome Gambit: No One Ever Won A Game By Resigning"  

It can be said that Stockfish 16.1, at 31 ply, evaluates the alternative 5...Ke8 as strong as 5...Ke6.

6.Qh5

angelcamina is 11 - 14 -1 in games with this position. Given that the computer rates Black as being 3 1/3 pawns better (30 ply), that is a decent result.

Also seen here is 6.c3. Play might continue 6...Nc6 (6...Kxe5 7.cxd4+ Ke6) 7.d4 Nxe5 8.dxe5 Kf7 (8...Kxe5 9.Qd5+ Kf6 10.Bg5+ Kg6 11.Qf5+ Kh5 12.g4#) 9.e6+ Ke8 (9...Kxe6 10.Qd5+ Ke7 11.Bg5+ Nf6 12.e5) 10.Qh5+ as in the twin games wolfpack123 - chessgeekdavidb, GameKnot.com 2006 and wolfpack123 - dbohm, GameKnot.com 2006 (1-0, 34).

6...Nf6 7.Qf7+ Kd6 

Black turns down the offer of a piece that he could have had with 7...Kxe5. With the clock ticking, quick decisions have to be made.

8.Nc4+ Kc5

8...Kc6 

If Black's King looks like he is in danger, that is because he is. He can survive his perilous position, but it will take care.

9.b4+ 

Throw another log on the fire.

9...Kxb4 

Skeptical. He figures he can give back a piece and survive.

10.c3+ Kb5 11.cxd4 

11...c6  

An escape hatch, if Black's King can reach it.

12.Nba3+ Ka6 13.O-O b5 

Probably better was 13...d5.

14.Ne3 Kb7 

White is now a pawn ahead, and Black has castled-by-hand, but the biggest disparity is the first player's lead in development.

15.e5 Nd5 

Stockfish 16.1 suggests the unpalatable 15...Ne8, instead.

16.Nxd5 cxd5 17.Qxd5+ Kb8 

18.d3 Bb7 19.Qxb5 Qg5

Time slip? Mouse slip? It is now essentially Game Over.

20.Bxg5 h6 21.Bf4 

Setting up a discovered check, showing that angelcamina always has tactics in mind. Still, 21.Rab1 would put Black out of his misery quicker.

21...g5 22.Bg3 Bg7 23.e6+ Kc8 24.e7 Black resigned

Checkmate in 3 is threatened.

Blackburne Shilling Jerome Gambit: Knight vs Knight

Mutual Knights threating enemy Rooks - the Blackburne Shilling Jerome Gambit has tactics across the board.

In the following game, Black pauses - and the game soon goes to his opponent.

Kmighty - Bibson24

10 0 blitz, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4

The Blackburne Shilling Gambit

4.Bxf7+

The Blackburne Shilling Jerome Gambit. 

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 

Each side enjoys Knight tactics.

7...Qf6

Black decides not to go down the rabbit hole of 7...hxg6 8.Qxh8 Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5, although it would bring him a small advantage.

However, this turns the game over to White.

8.Nxh8+ Kd8 9.d3 

Chosing not to horse around with 9.Nf7+ Ke7 10.d3 Qxf7 11.Qc5+ d6 12.Qxd4 - introducing a threat that is overlooked. 

9...Nxc2+ 10.Kd1 Nxa1 11.Bg5 Black resigned

Ouch.

Jerome Gambit: Blackburne Shilling / Kostic Jerome Gambit (Part 2)

 

[continued from the previous post]

IvanRusskih - zzzwww

Europa League 2022 - 2023 

                                      

We continue with a modern Blackburne Shilling Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ Ke7 

Possibly Black wanted to avoid 6...g6 7.Nxg6 hxg6 8.Qxh8, or wasn't interested in the continuing complications, e.g. 8...Nxc2+ 9.Kd1 Nxh1 10.Qxg8 Qg5 although they would leave him a bit better.

For perspective, The Database has over 2,100 games with 6.Qh5+, and Black found the 6...g6 line in 85% of them. Similarly, lichess.org has 77,336 games with the 6.Qh5+ line, and in 84% of the games Black found 6...g6.

The problem with the text is that White now has a forced checkmate with 7.Qf7+ Kd6 8.Nc4+ Kc5 9.Qd5+ Kb4 10.a3+ Ka4 11.Nc3#. 

Bad luck for IvanRusskih.

7.Nc3 

Okay, so zzzwww overlooked the line, too.

7...g6 

Too late, but I do not think that anyone could have conjured up Stockfish 16.1's suggestion: 7...c6 8.Qf7+ Kd6 9.d3 Ne6 10.Qf5 Ke7 11.Nf7 g6 12.Bg5+ Ke8 13.Qe5 Qb6 14.Nd6+ Bxd6 15.Qxh8 Nxg5 16.h4 Ne6 17.Qxg8+ Nf8 18.O-O-O Bf4+ 19.Kb1 d6 20.d4 Qc7 21.Qc4 Qf7 22.d5 Nd7 23.g3 and White is still better, but by not as much.

8.Nd5+ 

8...Ke8 9.Nxg6 

White offers the Knight, after all.

Black, in turn, would rather gain a Rook than surrender one.

9...Nxc2+ 10.Kd1 Nxa1 

He might as well.

11.Nxh8 checkmate

Quite nice.

Joseph Henry Blackburne would probably get a chuckle out of this particular ending to his gambit, even if it is Black who has to turn over his King.

Jerome Gambit: No One Ever Won A Game By Resigning

International Grandmaster Savielly Tartakower once mused that "No one ever won a game by resigning."

To that can be added the fact that in a 1-minute bullet game, just about anything can happen. 

angelcamina has over 1,200 games in The Database. The following win was recently added.

angelcamina - DiegoDac17

1 0 bullet, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+ 

Black was hoping for 4.Nxe5?!, so he could respond 4...Qg5!?

Instead, he meets the Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.Qh5 Qf6 

Black's defense of his King is solid, and his Knight threatens a fork at c2.

angelcamina has also tried 6...Nf6 7.Qf7+ Kxe5 8.f4+ in angelcamina - rabirabi, 1 0 bullet, lichess.org, 2019 (1-0, 13); angelcamina - shahramkhoshseffat, 1 0 bullet, lichess. org, 2019 (1-0, 13); and  angelcamina - luquitas2018, 1 0 bullet, lichess.org, 2020 (1-0, 21). 

7.Ng4 

Best. 

He had experimented with 7.Qe8+ without encouraging results: angelcamina - Skhokho1507, 1 0 bullet, lichess.org, 2019 (1-0, 12); angelcamina - Mohamed461, 1 0 bullet, lichess.org, 2019 (0-1, 21); angelcamina - reay, 1 0 bullet, lichess.org, 2020 (0-1, 17); angelcamina - Javier_Electrico, 1 0 bullet, lichess.org, 2021 (0-1, 22); angelcamina - Gab20, 1 0 bullet, lichess.org, 2021 (1-0, 15); and angelcamina - Pionputih_CSI, 1-0 bullet, lichess.org, 2022 (1/2 - 1/2, 18).

7...Qg6 8.Qd5+ Ke7 9.Ne5 Qd6

Better than 9...Nxc2+ 10.Kd1 and then 10...Qxg2 as in angelcamina -artemchumakov, 1 0 bullet, lichess.org, 2019 (1-0, 13) or 10...Qe6, as in angelcamina - regullele, 1 0 bullet, lichess.org, 2020 (1-0, 16). 

10.Qf7+ Kd8 11.d3 Nxc2+ 12.Kd2 Nxa1 13.Kd1 

A messy position with two uneasy Kings, but Black is better.

13...Nh6 

It is a mistake to take the Knight offside.

14.Bg5+ Be7 15.Bxh6 

The safer path, according to Stockfish 16.1, was 15.Qxg7 c6!? 16.Qxh8+ Kc7 17.f4 b5 18.Nd2 Bb7 19.Qg7 Ng8 20.Bxe7 Nxe7 21.Qxh7 - but remember, this was a 1-minute game: No human club player is going to figure all that out in seconds.

15...gxh6 16.Qg7 

Black need only safeguard his Rook, and things will be looking good.

16...Re8 

Oh, dear. Ask not for whom the bell tolls, it tolls for thee.

17.Nf7 checkmate

Blackburne Shilling Jerome Gambit: Queen or King?

In the following rapid game, Black is soon faced with an impossible choice.

ryuugu-rena - juen1234

10 0 rapid, lichess.org, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

Named the Blackburne Shilling Gambit, although I have not been able to find a Joseph Henry Blackburne game with this line.

4.Bxf7+ 

Named the Blackburne Shilling Jerome Gambit, although I have not been able to find an Alonzo Wheeler Jerome game with this line.

The Database has 7, 496 games with this position, with White scoring 57%.

ryuugu-rena has done a bit better: in 65 games, he has scored 65%.

4...Kxf7 5.Nxe5+ Ke6 

Bypassing the somewhat more popular 5...Ke8, this time.

The Database has 3,001 games with 5...Ke8, with White scoring 59%. 

Again, ryuugu-rena has done better: in his 24 games with 5...Ke8, he has scored 67%.

As for the text move, 5...Ke6, The Database has 2,133 games with White scoring 54%.

ryuugu-rena has played 5...Ke6 18 times, scoring 64%.

6.f4 

This move loosens White's Kingside.

Instead, Stockfish 15.1 recommends (30 ply) 6.c3 Nc6 7.d4 Nxe5 8.dxe5 d6 9.Qb3+ with an edge for Black. 

6...Bd6 

Hoping to eject the enemy Knight, but it is a costly mistake.

Taking advantage of White's last move would have been 6...Qh4+ 7.g3 Qh3 8.Nf3 Nxf3+ 9.Qxf3 Kf7 (Stockfish 15.1, 30 ply) when the first player would not have compensation in terms of attack for his piece-for-2-pawns sacrifice.

7.Qg4+ Ke7 

Alas, 7...Kf6 would lose his Queen to 8.Qg5+ Ke6 9.Qxd8. 

However, this move loses his King.

8.Qxg7+ Ke6 9.Qf7 checkmate
