Jerome Gambit: Theory and Practice (Part 2)

Another game from Vlastimil Fejfar. His opponent fearlessly offers a piece (matching the one Vlasta offered in the opening) for active counter-play, but the followup is marred by some inaccuracies, and once again the Jerome Gambit - and the gambiteer! - triumphs.  

Vlastous 2344 - Iva 1816
ChessManiac.com, 2016

1 e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+
Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.Nc3 



Varying from the previous game of Vlasta's that we took a look at, which saw 10.0-0 instead.

11.d4 Ng4 12.Qg3 Qf6 



Black builds his pressure on f2. Perhaps he avoided the reasonable 12...Nxf2 because of 13.O-O!? 

13.f3 h5 

Bold! Daring White to open up his King by taking the piece. (The "objective" Stockfish 7 prefers the Knight retreat 13...Nh6.)

After White chases the enemy Queen away from her attack on the pawn at d4, he accepts the piece. 

14.Nd5 Qf7 15.fxg4 Bxg4 16.Be3 Rc8 



Both Kings will remain in the center, but White's will be safer, and the first player has an extra pawn.

17.Kd2 Qd7 

This is a tactical oversight, as it un-protects his Knight, making his Bishop loathe to move.

Vlasta is quick to respond.  

18.h3 h4 19.Qxg4 Qxg4 20.hxg4 c6 21.Nc3 b6


White is clearly better.

22.Raf1 Rc7 23.Rf5 Rh8 24.Rg5 Nf8 25.d5 c5 26.Nb5 Rd7 27.Bf4 Rh6 28.Rf5 Rf6 29.g5 Rxf5 30.exf5 



30...g6

Allowing checkmate, but Black's position was untenable. White's material advantage is too great; Black's King is too vulnerable.

More Useful Junk


Readers of this blog probably remember Chris Torres. He hosts the Chess Musings blog.

He presented the Jerome gambit game Amateur - Blackburne, London  as "The Most Violent Chess Game Ever Played!"

He followed up with "Another Lesson in the Jerome Gambit", giving one of his own games.

He shared another game with the delightfully-titled post "Useful Junk: The Jerome Gambit".

Now he has sent me an FIDE-rated Jerome Gambit of his from the FIDE Online Arena.

Torres, Chris (chessmusings) - abhinam2
FIDE Online Arena, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 



Now Black has the choice of playing 7...d6, the Blackburne Defense, or 7...Qe7, the Whistler Defense. Instead, he opts for a "backatcha" move that at least gains him a pawn for his "doomed" dark-squared Bishop.

7...Bxf2+ 8.Kxf2 Nf6 9.Qf4

I thought I would share a few other ideas for this position, from games from The Database:

Perhaps not the risky 9...g5 10.Qf3 g4 as in instantcrow - KingEfraim, ChessWorld.net, 2005, (1-0, 25).

10.Nc3

Or 10.Rf1 Kg7 11.d4 h6 12.Kg1 Rf8 13.Qxh6+ Kf7 14.Qg5 Kg7 15.Qh6+ Kf7 16.Qg5 c6 17.e5 dxe5 18.dxe5 Ke6 19.exf6 Rxf6 20.Rxf6+ Ke7 21.Rxg6+ Black resigned, blackburne - Haroldlee123, ChessWorld, JG6, 2011. 

10...Kg7 11.d4 Rf8

Black is a pawn down, but he has castled-by-hand and his King is relatively safe. However, one of the "vital signs" that observers of all Jerome Gambits must note is the status of Black's light-squared Bishop, and its related Rook, as their under-development always are unhealthy symptoms. (See "A Lesson Learned From The Jerome Gambit" for one related "illness".)

12.Qh6+ Kg8 13.Kg1 Ng4 14.Qg5 Qxg5 15.Bxg5 Nf2 16.Nd5 Nxh1 17.Nxc7 Rb8 18.Kxh1 Bd7



White has two pawns for the exchange. Black can be happy that the Queens are off the board, but he cannot affort to be complacent. (He can be happy, for the moment, that his light-squared Bishop has moved and that his Rooks are linked, even if one is mysteriously developed.)

19.Nd5 Be6 20.Nf6+ Kg7 21.d5 Bc8

See the previous note.

22.Rf1 h6 23.Nh5+ gxh5 24.Bxh6+ Kxh6 25.Rxf8 



Materially, White has 3 extra pawns while Black has the extra piece.

More importantly, positionally, look at Black's Queenside: Code Blue! His weakness allows a "Jerome pawn" infection...

25...Kg7 26. Rd8 b6 27.Kg1 Ra8 28.e5 dxe5 29.d6 Bb7 30.Rxa8
Bxa8 31.d7 Kf7 32.d8=Q Black resigned



Very nicely done!

The Wisdom of The Database (Part 4)



We continue (see the earlier "Opening Report" parts 12, and 3) to uses ChessBase's Opening Report function to take a look at the games in The Database. 

As a reminder, the Report gathers what lines are being played, and what lines are being used by the top players in the database. It gives a good "real life" view of the play of the Jerome Gambit, even if it does not always identify the objectively best move or line.

The Return of Jerome Gambit for Dummies (Part 4)

As I continued looking for the "essence" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), or at least an insight into how it "works", I discovered that some of the 7-move games in The Database began to "predict" some of the regular main lines.

For example, in the following three games White's recovery of one of the pieces that he had sacrificed is enough for Black to surrender, even though the second player actually remained with the advantage.

Some of the other short games began to highlight the attacking ideas open to White in the Jerome Gambit, if the defense faltered.

"I don't get it"


Part of the fun of preparing games for this blog is looking into them and uncovering the logic (or illogic) behind a plan or a series of moves by one player or the other. This can bring to light all kinds of "errors of thinking". It can also leave me scratching my head in wonder, murmuring "I don't get it." 

The following game features blackburne, the top over-the-board (not just online) Jerome Gambit player, and Haroldlee123, who scored two serious upsets in the Chess World Jerome Gambit Thematic Tournament. 

blackburne - Haroldlee123
Jerome Gambit Thematic Tournament
ChessWorld, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6


7.Qxe5 Bxf2+

I found 68 games in The Database with this move. White scored 67%.

8.Kxf2 Nf6


Most often Black has played 8...Qf6+, when "At the cost of exchanging a won game for one in which he is a pawn down, Black has reached a Queenless middlegame that is not what every Jerome Gambiteer wishes for." (See "Short and Unbecoming")

9.Qf4 d6 10.Rf1 Kg7 11.d4 h6 12.Kg1


Both sides have castled-by-hand.Black's next move was played too quickly and gets him in immediate danger.

12...Rf8 13.Qxh6+ Kf7 14.Qg5 Kg7 15.Qh6+ Kf7 16.Qg5

The games in this tournament were played with a time limit of 5 days per move, but there was nothing to prevent opponents from playing faster if they ran into each other online. That's what seems to be going on here. White is repeating the position for what reason? I don't get it. (Perhaps: psychology.) Certainly 16.Bg5 would have kept the heat on.

16...c6


Black is avoiding repeating the position (by 16...Kf7) for what reason? I don't get it. He is down two pawns and should be thrilled with a draw. Instead, the text tosses a piece.

17.e5 dxe5 18.dxe5 Ke6 19.exf6 Rxf6 20.Rxf6+

The endgame, a piece and a pawn up, will be pleasant. White could have played sharper with 20.Re1+ Kg7 21.Qh4, but why bother? Remember, each player had 28 games to contend with.

After Black's response there are a number of checkmating lines available, and White chooses one.

20...Ke7 21.Rxg6+ Black resigned

Favorite Checkmate


Haroldlee123 - klonka
 Here we have my favorite checkmate from the lingering Chess World Jerome Gambit Thematic Tournament.

White has just played 69.e7 checkmate.

He might just as well have played 69.Bh6#.

Promoting three pawns to Queens and sacrificing one would have been a bit too much: 69.d7 Ke7 70.f8/Q+ Kxe6 71.d8/Q Ke5 72.Qf5#

There Be Monsters...

If the Jerome Gambit were simply a way for White to lose quickly – and at higher levels of play, it certainly is – then defenders would face it with calm assurance and not find its attacks to be frightening at all. On the other hand (or board), sometimes the Jerome can have a "bark" that is far worse than its "bite." For example...

Knight32 - Haroldlee123
Jerome Gambit Thematic Tournament
ChessWorld, 2011


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


This is not the first exposure to the the Jerome Gambit for either player. Likely, they have heard tales...

4...Kxf7 5.c3 Nf6 6.Ng5+ Kg8 7.Qb3+ Black resigned


Wow! Black plays 7...Kf8 and then White plays 8.Qf7 checkmate. It doesn't get much simpler than that.

(Unless Black sees 7...d5, instead.)

Sunday Tournament Update

A baker's dozen games (about 6% of the total) remain to be completed in the ChessWorld Jerome Gambit Thematic Tournament.

While AsceticKingK9 has taken first place, and a number of other finishing positions have been determined, martind1991 still can place anywhere from 8th to 15th place, depending how his games finish up.

For the time being, at least, Haroldlee123 has pulled off the two top upsets, beating players rated 411 and 329 points above him.

Sunday Tournament Update

Elvis has left the building.

After rocketing to the top of the chart with a score of 25 points in 25 games in the Chess World Jerome Gambit Thematic Tournament, AsceticKingK9 has lost his first game – on time – to Haroldlee123. His remaining two games, against martind1991, are over the time limit as well, but have not yet been claimed.

Not that it matters. 25 points is enough to win the tournament. (Oddly enough, early on I predicted that the winner would score 24 points. AsceticKingK9 exceeded that number, but 24 would have been enough to put him ahead of the second place finisher. Lucky guess!?)


Second place has been wrapped up by mckenna215, with a score of 23.5 out of 28 games. 


Third, fourth and fifth places remain a tangle. Knight32 has 18.5 points out of 28 games. Braken has the same score, with one game remaining. Rikiki00 has 15.5 points in 23 games.


It should be pointed out that Haroldlee123, currently in 10th place with 8 points out of 22 games, nonetheless now has upset wins over both AsceticKingK9 and mckenna215

Sunday Tournament Update

The ChessWorld Jerome Gambit Thematic Tournament is underway, all 15 competitors and all 210 games!

We are already seeing results (8 completed games so far, 6 wins by White) from AsceticKingK9, mckenna215, Rikiki00, braken, blackburne, DREWBEAR 63, Knight32, Magni, pixifrufru, shm19cs, klonka59, Baron wd von Blanc heart pirate, martind1991, Luke Warm and Haroldlee123.

Many games are in their early stages, others are racing along.

There are a number of examples of the Jerome Gambit Declined (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8/Ke7) a relatively rare beast making up only about 9/10th-of-a-percent of the games in The Database those certainly will expand our understanding of that line.

At least 29% of the games are "classical" Jerome Gambits, with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7+ followed by 5.Nxe5+, which is the highest percentage that I have seen in a recent Jerome Gambit thematic tournament. Some "well established" theory is likely to be stood on its head by the time those games are done!

With about 7 out of 10 games following "modern" (non-5.Nxe5+ lines) there will be plenty of practice to round out the theory of this more tempered approach as well.

Next Sunday I will give further information on the progress of the tournament. When all games have developed far enough for me not to influence their play, I will begin presenting some with annotations.

(By the way, I predict that the tournament winner will score 24 out of 28 points.)
