Jerome Gambit: Different Line, Same Result

The latest internet game from Vlasta Fejfar shows that the Jerome Gambit is not just a one-time-surprise opening. Having fallen to the Jerome, his opponent reassesses his chances and his line of play, and tries something new. Alas, for the defender, White still triumphs.

vlastous - ADELAZIZ
internet, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 



The Jerome Defense, courtesy Alonzo Wheeler Jerome, who also brings you the Jerome Gambit.

7.Qxe5 d6 8.Qf4+ Nf6 



ADELAZIZ varies from the 8...Qf6 that he played when the two contested a game earlier. Then, vlastous was willing to exchange Queens and make his extra "Jerome pawns" count.

9.O-O Bd4 10.c3 Be5 


Reminding me of perrypawnpusher - warwar, "Italian Battleground", Chess.com, 2019 - but in current game, things turn out better for White.

11.Qh4 g5 

A smart move. Taking the pawn would expose White to dangers along the g-file.

12.Qh6+ Kf7 13.d4 Bf4 14.Bxf4 gxf4 15.e5 dxe5 16.dxe5 Nd5 17.Re1 Be6


Black still has a piece for two pawns, but the uneasy position of his King suggests that if anyone has an edge, it is White.

18.c4 Nb4 19.Nc3 Rg8 20.Ne4 Nd3



The Knight attacks White's Rook and pawns, while protecting his advanced pawn. However, a pin along the d-file will cause trouble. Better was 20...Qe7, Which could also be answered by 21.Rad1.

21.Rad1 b6 

Now the roof falls in.

22.Rxd3 Qxd3 23.Qf6+ Ke8 Black resigned



Black will lose his Queen (and more) or be checkmated.

Jerome Gambit: Faster and Faster

The following bullet (one minute, no increment, time control) online game starts off in regular Jerome Gambit fashion, but things then turn bad for Black, who keeps rolling down the hill, faster and faster. The King hunt at the end is brutal.

angelcamina - Kvngmicky
1 0 bullet, lichess.org, 2019

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6

The players have reached a regular Jerome Gambit position - at breakneck speed.

10.O-O Ng4 11.Qf3+ 

A new move, according to The Database.

11...Nf6 12.d4 Ke7 13.Bg5 Kd7 14. Nc3 c6 15.Rad1 h6 16.Bc1 Qe7 17.Rfe1 Kc7

White is ready to go.

18.e5 dxe5 19.dxe5 Nxe5

The pawn is poisoned.

20.Bf4

This works, but so does 20.Rxe5 Qxe5 21.Bf4.

21...Nfd7 21.Qg3 

Again, a solid move. With more time, angelcamina would have found 21.Rxd7.

21...Kd8 

Black's position now collapses like a house of cards.

22.Bxe5 Ke8 23.Qg6+ Qf7 24.Bxg7+ Kd8 25.Qxf7 Kc7 26.Bxh8 Kb6

There is no place safe for Black's King.

27. Bd4+ c5 28.Nd5+ Ka6 29.Bc3 b5 30.Qe6+ Kb7 31.Nb4 Kb8 32.Rxd7 Bb7 33.Qe8+ Bc8 34.Rd8 Kb7 35.Re7+ Kb6 36.Qc6+ Ka5 37.Nd5+ b4 38.Bxb4+ Black resigned



All of White's pieces participate in the checkmate attack, while Black's remain, unfortunately, at home.

Jerome Gambit: Previously, In the Precomputer Era

!!!!!
Wandering the internet the other day, I ran across a Russian language chess site that teased
Previously, in the precomputer era, often against obviously weaker rivals, we played like this: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7 +?
My computer offered to translate the site to English, and I found it lots of fun.

(There is a link to this web site, as well as lichess.org.)

There is also some cogent advice
...Indeed, the dynamic capabilities of the position are a lot of trouble for Black.Therefore, it is useful to play this beginning against the engine both for whites and blacks - this will definitely contribute to the growth of tactical skill. 
The author has done his homework. The infamous game NN - Blackburne, of course, is given, but there is also with Jerome - Brownson, Iowa, 1875; Lowe - Cudmore, corr, 1881; Keeble - Cubitt, Norwich, 1886; Sorensen - X,  Denmark, 1888; and even Wall - Bison engine, 2015

It is well worth a visit.

Jerome Gambit Declined: Grumping, Yet

While I'm on the topic of the Jerome Gambit Declined, I thought I would dig a little deeper...

MrJoker - david2play
2 12 blitz, Internet Chess Club, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8 



The Jerome Gambit Declined.

Certainly, strongest for Black was 4...Kxf7, but on rare occasions the defender decides If you want me to take the Bishop, I won't take the Bishop. That being the case in this game, the Black King is probably better off on f8 as opposed to e7.

5.Bxg8 

The typical argument can otherwise ensue, where best to retreat the Bishop, d5, c4 or b3?

MrJoker's solution, of course, is playable. I will leave the discussion of 5.b3, 5.c3, 5.Nc3, 5.d3, 5.d4, 5.Nxe5, 5.Qe2, 5.0-0, 5.Ng5 and 5.Bh5 (all are in The Database) for later posts.

5... Kxg8 6.O-O 

A reasonable move, played by HauntedKnight, Petasluk, shugart, Superpippo, Wall, and others, as well.

6...d6

For 6...Qf6 see Wall, Bill - Guest558953, PlayChess.com, 2017 (1-0, 15).

Looking at the diagram, you can ask yourself What does Black have for his gambitted pawn? Not very much - but he is playing his own game.

7.c3 h6 8.d4 exd4 9.cxd4 Bb4 



Better to have retreated the Bishop, as White shows.

10.Qb3+ Kh7 11.d5 Ba5 12.dxc6 bxc6 13.Nc3 Re8 14.Bd2 Bb6 15.Rad1 Ba6 

Black is developing, but White, as a Jerome Gambit player, must enjoy being the player with the extra piece.

16.Rfe1 Qf6 17.Be3 Ba518.Bd4 Black forfeited on time




Black's future was not bright, anyhow.
