Jerome Gambit: How Much Do You See?

In a game with a time limit of 1 minute, no increment, you have to rely on a quick assessment of the board. It helps if you have had similar positions in past games, if you are familiar with relevant strategic and tactical themes, and if you have confidence in your ability to make your way through a complicated game.

angelcamina demonstrates.

7.Qd5+ Kf8 8.Qxc5+ d6

angelcamina has also faced 8...N8e7 in  angelcamina- southerngumbo, 1 0 bullet, lichess.org, 2019 (1-0, 40)  and angelcamina - Claim1, 1 0 bullet, lichess.org, 2019 (1-0, 31).

He met 8...Qe7 in angelcamina - mustapha1996, 1 0 bullet, lichess.org, 2019 (1-0, 32).

9.Qe3 Nf6 10.O-O 

A small improvement over 10.Nc3, which he played in angelcamina - JsFlexWay, 1 0 bullet, lichess.org, 2018 (1-0, 19) 

10...Qe8 

On the other hand, this is not quite as strong as 10...Ng4  that angelcamina faced in angelcamina -Kvngmicky, 1 0 bullet, lichess.org, 2019 (1-0, 38) and angelcamina-Cubigami, 1 0 bullet, lichess.org, 2019(1-0, 27).

11.Nc3 c6

Designed to keep White's Knight of d5, but he would have been more prudent to castle-by-hand.

12.f4 Ng4 13.Qg3 h5 

14.h3 Bd7

A bold idea, and somewhat of an explanation why he did not castle-by-hand - he wants to use his Rook on a hopefully opened h-file. Will it succeed? Will White defend adequately? In bullet games, anything can happen.

15.hxg4 

Taking the piece, trusting in his attack on the enemy King.

15...hxg4 16.d4 Qe7

17.e5

White judges that it is time to break in the center. His preparations also would allow for 17.f5!?, which is sharp, if complicated, winning another piece.

17...d5

Stockfish 10 recommends, instead, that Black continue with pressure on the Kingside, i.e. 17...Nh4 18.f5 Nxf5 19.Qxg4 Kg8 20.Bg5 Qf7 21.Rae1 Qh5 22.Qxh5 Rxh5 23.Bf4 Nxd4 24.exd6 Ne6, when it is not very concerned about White's extra, passed pawn.

18.f5 Nh4 19.Qxg4 Ke8 

He could have tried, instead, to hold on by giving up two pieces for a Rook and a pawn, with 19...Nxf5 20.Rxf5+ Bxf5 21.Qxf5+ Kg8. White would still be better, but it would be a complicated win to achieve.

White now wins the offside Knight, and concludes the game quickly.

20.Bg5 Qb4 21.Bxh4 Qxb2 22.Qg6+ Kf8 23.f6 Qxc3 24.fxg7+ Kg8 25.gxh8=Q+ Kxh8 26.Bf6 checkmate

Jerome Gambit: The Goal Is Not A Quick Draw

Here is another 1-minute, no increment game from angelcamina. White's play is calm and brutally effective.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 

A popular solution to the fork. The Database has 313 games with this position; White scores 57%.

7.c3 Bxc3+ 8.bxc3

I think that capturing with the Knight is stronger, but the most important point in this 1-minute game is that White has a plan for how the game will progress. 

8...Nc6 9.O-O Nf6 

10.e5 Nd5 

Careless.

Stockfish 10 is not a fan of the Jerome Gambit. It recommends for Black, instead, 10...Ne8, and then sees the best outcome for White to be 11.Qf3+ Kg8 12.Qd5+ Kf8 13.Qf3+ with a draw by repetition. I can not imagine angelcamina going for that line - you do not play the Jerome Gambit in a bullet game to achieve a quick draw.

11.Qf3+ Ke8 12.Qxd5 d6 

White has an extra pawn, but what really matters is Black's vulnerable King, which can be exploited for further gain.

13.exd6 Qxd6 14.Re1+ Ne7 15.Qxd6 cxd6 16.Bg5 

Tactics.

White finishes up in short order.

16...Kd7 17.Rxe7+ Kc6 18.Nd2 h6 19.Be3 Rf8 20.c4 b6 21.d5 checkmate

Very smooth.

BSJG: An Improvement Is Not Always Enough

White is on familiar ground in the following game, and he seems quite prepared when his opponent improves on earlier defenses White has faced. Alas, for Black, he needed to continue improving, in order to win the game; and there doesn't seem to have been time for that.

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 

Instead, 6...Ke7 was punished quickly in angelcamina - umutkaraca09, 1 0 bullet, lichess.org, 2019, (1-0, 9).

7.Nxg6 hxg6

An improvement over:

7...Nf6 in angelcamina - Skhokho1507, 1 0 bullet, lichess.org, 2019, (1-0, 19);

7...Qf6 in angelcamina - felix_paton, 1 0 bullet, lichess.org, 2019, (1-0, 12); and

7...Nxc2+ in angelcamina - eloali, 1 0 bullet, lichess.org, 2019, (1-0, 30). 

8.Qxh8 Ke7

A mistake, and a losing one. At first, it looks like a mouse slip for 8...Kf7, although White would then be better after 9.Qxd4.

Black had to accept the Rook sacrifice with 8...Nxc2+ followed by 9...Nxa1, but there are times in the Blackburne Shilling Jerome Gambit when that is wise, and there are times when that is not very wise; in a 1-minute game, it can be hard to know which case this is.

Now White collects the Knight a d4, castles, and is a comfortable exchange and 3 pawns up.

9.Qxd4 Ke8 10.O-O Be7 

11.f4

Cold-hearted was 11.Qg7!?, but the text fits into White's plan. 

11...Nf6 12.e5 Ng4 13.f5 b6 

Drops another piece, but nothing works.

14.Qxg4 gxf5 15.Qg6+ Kf8 16.Rxf5+ Bf6 17.Rxf6+ Ke7 18.Rf7+ Ke8 19.Qg8 checkmate

Jerome Gambit: Check the Notes

Is Black's defense to the Jerome Gambit in the following game acceptable?

Of course. 

Does it give him practical chances? 

Of course. (Check the notes, and you will find a couple of draws against Bill Wall, and even a very rare win against him.)

Does Black win?

Of course not.

Once again, the defender is able to grasp loss from the jaws of victory - as so often happens in the Jerome Gambit.

11.Re1 d6 12.f4 Neg4 13.Bd4 Kg8 

Black has castled-by-hand. If he works on his development, he can make something of his piece-for-a-pawn advantage.

White's job is to disrupt Black's plans.

14.h3 Nh6 15.g4 c5 16.Bf2 Be6 

This is a funny oversight. Often, in the Jerome Gambit, Black has to be careful that when he plays his Bishop to e6, that it doesn't become a victim to a pawn fork. This move allows a fork - of the two Knights.

17.g5 Nf7 

Possibly 17...Nxe4 18.Nxe4 Ne5 was better.

18.gxf6 Qxf6 19.f5 

19...Qg5+

Energetic, and focused on the enemy King, but possibly the start of some "smites" that are too shallowly considered.

20.Kh2 Bc4 21.b3 Qf4+ 

White's answer is sufficient. 

Black's attack on the King is an illusion, as will be seen.

22.Bg3 Qh6 23.bxc4 Ng5 24.h4 Re7 25.Qg4 Nf7 26.Nd5 Ree8 27.Bf4 Black resigned

Black's Queen is in trouble. There is an immediate defense, but, in the long run, White's pressure on the Kingside will prevail, e.g. 27...g5 28.Bxg5 Qg7 29.Qh5 Nxg5 30.hxg5 Re5 (to avoid the Knight fork) 31.Nf6+ Kh8 32.g6.

Jerome Gambit: Occasional Inattention

There are many ways to defeat the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), but relaxing too soon is not among them. In the following game, the defender plays a spirited game, marred only by occasional, deadly, inattention.

Wall, Bill - Guest564723

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ 

The "nudge".

7...Ke8 8.Qxc5 d6 9.Qe3 Nf6 

10.f3 Be6 

Since White's f-pawn has taken only one step, instead of two, Black's Bishop feels safe coming to this spot.

Bill has seen 10...Kf7 twice: Wall, Bill - Guest3544144, PlayChess.com, 2013 (1-0, 35) and Wall, Bill - Guest1105387, PlayChess.com, 2014 (1-0, 30).

11.f4

Threatening to advance and fork two pieces, after all.

11...Ng4 12.Qg3 Qh4 13.Qxh4 Nxh4 

White's dangerous Queen has been exchanged. Black still needs to be wary. Instead, he relaxes too soon.

14.O-O Ke7 15.f5 Bc4 16.d3 Ba6 17.Bg5+ 

17...Kd7 18.Bxh4 Ne3 19.Rf2 Ng4 

Does Black really hope for a draw by repetition?

20.Rf3 Rhf8 21.Rg3 Nh6 

22.Rxg7+ Rf7 23.Rg3 d5 24.Nc3 c6 

25.b4 Re8 26.Bg5 Ng8 27.a4 d4 28.Ne2 c5 

Black's pieces do not coordinate. Black is a bit too focused on some pawns, and not on others; hence, this slip. 

29.b5 Black resigned

Jerome Gambit: No Automatic Moves, Please

There are many ways to refute the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+), but none of them occur by accident. Black has to pay attention, think things through, and avoid making moves automatically, on the presumption that they have to be "good".

Wall, Bill - Guest3174027

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.a4 

Bill likes to experiment. You might think that this move is a novelty, but, according to The Database, it has been played before - by Bill. Will a Bishop go to a3? A Rook? Or is this more of Jerome Gambit "psychology"?

8...Nf6 

Previously 8...h6 was seen: 9.O-O Nf6 10.Nc3 a6 11.f4 Nc6 12.Qd3 Rf8 13.Bd2 Kg8 14.Qc4+ Kh8 15.Rfe1 Bd7 16.Nd5 Nxd5 17.exd5 Ne7 18.Ba5 b6 19.Bd2 c5 20.dxc6 Bxc6 21.Rxe7 Qxe7 22.Qxc6 Rac8 23.Qxb6 Rxc2 24.Re1 Qf6 25.Qe3 Qxb2 26.Rd1 Rfc8 27.f5 d5 28.h3 a5 29.Kh1 d4 30.Qd3 R8c4 31.f6 gxf6 32.Qg6 d3 33.Qxh6+ Kg8 34.Qg6+ Kf8 35.Re1 Black resigned, Wall, Bill - Guest7904333, PlayChess.com, 2018

9.Nc3 c5 10.Qd2 Re8 11.O-O Be6 

So far, Black has a piece for a pawn, and his development is better. He must stay away from "automatic" moves, however.

12.Rd1 d5

This move winds up dropping a piece, leaving White a pawn up.

13.exd5 Bxd5 14.Nxd5 Nxd5 15.Qxd5+ Qxd5 16.Rxd5 Nc4 

White is a pawn up. He does not risk losing, but he still needs to be careful, in order to find the win. 

17.h3 Re1+ 18.Kh2 b6 19.b3 Ne5 20.Bb2 Re8 

A slip, but there was little hope in 20...Rxa1, 21.Bxa2 Nc6 22.Rd7+ Ne7 23.Bxg7 Kxg7 24.Rxe7+ when White would simply be up a couple of pawns in the endgame.

21.Rxe1 Black resigned
