Jerome Gambit: Stunned

If a defender is not familiar with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), missteps are easy to find. The following game is one example as to how the opening can be effective in club play - one slip, and Black has passed the point of no return.

RedHotPawn.com, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke8 

Black turns the advantage over to White, in order to not play along with the attacker's plans. For a recent example, see "Jerome Gambit: Disease 1, Cure 0".

6.Qh5+ 

The consistent 6.Nxc6 is stronger, although it could lead to the aggressive 6...Qh4!? (There are still no examples of this move in The Database.)

6...g6 7.Nxg6

The Database has 38 games with this position. White scores a hefty 72%.

7...Qf6 

For an earlier discussion of this line, review "Jerome Gambit Secrets #3".

Black's strongest response was 7...Bxf2+, leading to a small advantage for him, after 8.Kxf2 Nf6. The earliest examples that I have of 7...Bxf2+ are the twin games Hultgren, R - Harrow, and Blackstone, J - Dommeyer, C, both played in Campbell, California and both played in 1960. Sadly - for Black - The Database has 10 games with the move, with White winning 8 of them.

8.Nxh8+ Ke7 9.d4 

9...Bxd4 

Tripping over White's out-stretched foot... 

10.Bg5 Bxf2+ 11.Ke2 Black resigned

Jerome Gambit: More GMs? (Part 1)

I received an interesting email from "Cliff Hardy" the other day. In it, he notes

In the post about my game vs the Cuban GM, "A GM Faces the Jerome Gambit (Part 2)", you mentioned the virtually mistake-free game:  ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org, 2017: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 8.Qg3 Nf6 9.d3 Qd7 10.Nc3 Qg4 11.Qxg4 Bxg4 12.h3 Be6 13.Be3 Bxe3 14.fxe3 Ke7 15.O-O Rhf8 16.Nb5 c6 17.Nd4 Nd7 18.a4 Rxf1+ 19.Rxf1 Rf8 20.Rxf8 Nxf8 21.Kf2 g6 22.Nf3 Nd7 23.b3 a5 24.Ke2 Nc5 25.e5 dxe5 26.Nxe5 Kd6 27.d4 Nd7 28.Nd3 Bf5 29.g4 Bxd3+ 30.Kxd3 b5 31.axb5 cxb5 32.e4 a4 33.bxa4 bxa4 34.h4 a3 35.Kc3 Nb6 36.Kb3 Nc4 37.c3 Nd2+ 38.Kxa3 Nxe4 39.c4 Black lost on time; in which black maintains a winning advantage the whole game (from move 4), according to the Stockfish feature on Lichess (but loses on time in a winning position). I mentioned in a comment to the game that, in a slight anticlimax to my game being a rare example of a GM facing the Jerome Gambit, the black player PArnaudov is also a GM! https://lichess.org/@/PArnaudov

This certainly got me thinking! I responded quickly

The game ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org, 2017, is a good example of why some skeptical people see the Jerome Gambit as only playable in very quick games. Black can figure it all out, but it might take too much time. Certainly angelcamina has found this out with his 1 0 games.

I was interested in learning that PArnaudov is a GM... 

For fun, I went to The Database and did a search for games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ and "ratings > 2500". I found 25 games, with 6 games where White was >2500. 

Wow! I was going to check out the games where the 2500+ player played the Jerome Gambit, first. The relevant games in The Database were all played online, not over-the-board.

One game was by BlackDemon, at FICS; it's a computer account; still, it might be fun to see if the Jerome is/was part of its book, the way "Brause" was set up to play the Halloween Gambit... 

Two of the games were by Topper76, at redhotpawn.com, in a Kentucky Opening tournament; I will have to track him down. Oddly enough, he won one Jerome Gambit game, on time, in 7 moves, and lost the other to a player rated 2421. 

Three of the games were by ChessCoachUA, at lichess.org - in fact, he was rated 2394, 2453, 2519, 2530, 2514 and 2459 on the site, for 6 Jeromes. Alas, ChessCoachUA's lichess.org account was listed as "closed", when I tried to check up on him.

Concerning the FICS computer account BlackDemon, I went to the online FICS games database, and found only 2 Jerome Gambits that it played with White, both in TheDatabase, one where the computer was "only" rated 2347 on the site. As a silicon beast, it couldn't be a grandmaster "in real life", anyhow.

I could not find a Topper76, at redhotpawn.com or elsewhere. Of course, those Jerome Gambit games were from 8 years ago, so the player may have moved on.

The ChessCoachUA story is a bit more complicated, and I had slipped up in my response to Cliff, above. The Database has 2 games by ChessCoachUA, as well as 2 games by ChessCoach_UA, and 4 games by ChessCoach1985. All of the players have lichess.org accounts listed as "closed", so it was not possible to do the kind of research that Cliff Hardy did with PArnaudov (above), to see if we were dealing with a GM in real life.

I tried, though.

I could find nothing on ChessCoach1985.

On the other hand, ChessCoach_UA, could well be Vasily Burishin, of Kiev, Ukraine. I could not find an FIDE rating.

I did find a ChessCoachUA at Chess.com - Alexey Pugach, of Dnepr, Ukraine, whose FIDE Chess Profile lists his rating as 1985. Of course I messaged him.

So - the search to find a human GM (FIDE rating, not online site rating) has not (yet) been successful.

Jerome Gambit: A Bit of Strangeness

I just stumbled over a bit of strangeness, which, in the Jerome Gambit world, is saying something.

The "2014 October Giuoco Piano Jerome gambit" tournament at RedHotPawn was actually a two-game match between SeinfeldFan91 (2223) and Swiss Toni (2088).

We have seen SeinfeldFan91's games before.

The games:

SeinfeldFan91 - Swiss Toni
October Giuoco Piano Jerome gambit tournament, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Black resigned

Swiss Toni - SeinfeldFan91 - Swiss Toni
October Giuoco Piano Jerome gambit tournament, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Kxf7 White resigned

I guess I understand why I couldn't find these games in The Database.

Jerome Gambit: Smothered

Sometimes the finish to a game is the most sparkling part. Witness the following between Bill Wall and an opponent who will remain anonymous.

For all practial purposes, the game has been over for a while - but Black has been hanging on. Not for much longer, though.

28.Nf7+ Kg8

Now White has the routine discovered check 29.Nd8+, and the game ends either after 29...Kf8 30.Qf7# or 29...Kh8 30.Qe8#.

Why overlook a Queen sacrifice and a smothered mate, however? There is double, discovered check.

29.Nh6+ Kh8

Instead, 29...Kf8 30.Qf7# is again routine.

30.Qg8+ Rxg8 31.Nf7 checkmate

Nice.

Recall the game rigidwithfear - golddog2, Jerome Gambit Tournament, RedHotPawn.com, 2016 for another smother.

It is interesting that The Database has 8 games with the same checkmating pattern, including 2 that ended with an unforced ...Rg8 followed by Nf7#.

Jerome Gambit: A Workaday World

Although the Jerome Gambit can be a lot of help, sometimes White has to rely on  his ability to outplay his opponent. The following game, by the winner (undefeated) of the recent RedHotPawn.com Giuoco Piano Jerome Gambit Tournament, shows how it is done.

SeinfeldFan91 - rigidwithfear
Jerome Gambit Tournament, RedHotPawn.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qd5+ Be6 9.Qxb7 

This is a popular pawn-grab which is a bit riskier than, say, 9.Qb5, but White is willing to take the chance. 

9...N8e7 10.Nc3 Rf8 11.d4 Kg8 

Black has wisely castled-by-hand and has the better development. He now faces the challenge that many defenders face: how to take advantage of having the advantage. He seems unsure in the task.

12.d5 Bd7 13.O-O Ne5 14.f4 Nc4

It does not appear that a lot has happened, and that is part of the problem for Black. Stockfish 7 now rates the position as equal. I would call it "messy".

15.Qa6 Nb6 16.f5

An interesting clamp on the position, and there is always the threat at some point in the future of f5-f6.

16...Bc8 17.Qe2 Bd7 18.Bg5 Qe8 19.a4 Rb8 20.Qa6 Qf7 21.Qxa7 

21...Nc4 22.Qxc7 Nb6 23.Qxd6 Rfe8 24.a5 Black resigned

White has been busy gathering pawns - he has 6 for his sacrificed piece - and now he attacks the Knight at b6 that protects the Bishop at d7; one of them must fall.

Jerome Gambit: The Nightmare Before Christmas

I borrowed part of the title of this blog post from Tim Burton's animated film, but it seemed to be about right in describing the following game.

Those who play the Jerome Gambit need to constantly remind themselves that it is, technically, a refuted opening, and that there are a number of winning defenses that Black can play.

True, there are many circumstances which lead to the defender not making use of his advantages, and White wins - sometimes quite impressively. Learning to take advantage of any slip or error is critical.

However, sometimes there are games like the following. SeinfeldFan91 won the RedHotPawn.com Jerome Gambit tournament by succeeding in all of his games - and that means wins with Black, as well as wins with White.

kristjan - SeinfeldFan91
Jerome Gambit Tournament, RedHotPawn.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

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

At first Alonzo Wheeler Jerome favored this move over 6.Qh5+, and it has much going for it - including winning back one of White's two sacrificed pieces.

A quick look at The Database (which is a good measure of club player success, not necessarily "theoretical" or computer success) shows 1,499 games with 6.d4, with White scoring 52%. This can be compared with 3,793 games with 6.Qh5+, with White scoring 55%.

6...Qh4 

This is the strongest theoretical response to 6.d4, and it appears in 230 games in The Database. However, as a measure of how chaotic the game becomes in this double-edged variation - White scores 67%!

This is another indication that familiarity and understanding of the Jerome Gambit is very important: Play what you know, and know what you play.

7.dxc5

Here the Database statistics line up with the recommendations of the computers. The text move appears in 67 games with White scoring 28% - not bad when considering that the line is "lost" for the attacker, but not best. There are 154 Database games with the also "lost" (but better) move 7.0-0, and White scores 87% - it is always good to understand your practical chances in a wild line! 

7...Qxe4+ 8.Kf1 Nf6 9.Nc3 Qb4 

Some alternatives:

9...Qh4 10.Be3 b6 11.Ne2 bxc5 12.Ng3 d6 13.c3 Ba6+ 14.Kg1 Rhe8 15.Qb3+ c4 16.Qd1 g6 17.Kf1 Neg4 18.Bd4 Nxh2+ 19.Kg1 Nfg4 20.Qd2 Bb7 21.Qf4+ Kg8 22.Rxh2 Qxh2+ White resigned, HauntedKnight - blocbloc, FICS, 2016;

9...Qc4+ 10.Kg1 Qxc5 11.Be3 Qe7 12.g3 d6 13.Kg2 Bg4 14.Qd2 Bf3+ 15.Kg1 Bc6 16.f4 Nf3+ White resigned, HauntedKnight - truuf, FICS, 2014; and

9...Qc6 10.Bg5 Re8 11.Bxf6 Qxf6 12.Nd5 Qf5 13.Nxc7 Ng4 14.Qd5+ Qxd5 15.Nxd5 Re5 16.c4 b6 17.cxb6 Ba6 18.b3 axb6 19.Nxb6 d5 20.Nxa8 dxc4 21.Nc7 Rf5 22.Nxa6 Nxf2 23.Kg1 c3 24.Rc1 Ne4 25.Nb4 Rf2 26.Rxc3 Rb2 27.Rf3+ Ke6 28.h3 g5 29.Kh2 h5 30.Re1 Ke5 31.Nd3+ Black resigned, PasChat - plamb, FICS, 2014

10.g3

At this point something like 10.Be3 to focuse on development was probably better. Still, the situation is grim.

10...d5 11.Kg2 Bg4 12.Qe1 Rhe8 White resigned

Playing on a piece down, with the loss of more material imminent, was not appealing.

Jerome Gambit: On the Way to Victory

Here is another fine win from the top player in the recent RedHotPawn.com Jerome Gambit tournament.

SeinfeldFan91 - junnujannu
Jerome Gambit Tournament, RedHotPawn.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.O-O Qe7 

11.Nc3 c6 12.d4

Also seen in this position:

12.d3 Ng4 13.Qe2 Qh4 14.h3 N4e5 15.f4 Nf7 16.Bd2 Qe7 17.Rae1 Kd8 18.Qh5 Qh4 19.Qa5+ b6 20.Qb4 Kc7 21.d4 a5 22.Qc4 Qe7 23.Nd5+ Kd7 24.Nxe7 Kxe7 25.Qxc6 Bd7 26.Qxb6 Rab8 27.Qxa5 Rxb2 28.f5 Nh4 29.e5 dxe5 30.Qc5+ Kf6 31.dxe5+ Black resigned, shugart - volki, FICS, 2013; and

12.f4 Kd8 13.d4 Kc7 14.f5 Nf8 15.e5 dxe5 16.dxe5 Ng4 17.Qd4 Nh6 18.f6 gxf6 19.Bf4 Black resigned, Wall,B - HeHe, Chess.com, 2010.

12...Be6

Development (with a subtle flaw).

Black has also attacked the Queen, as a prelude to a push on the Kingside: 12...Ng4 13.Qg3 h5 14.h3 h4 15.Qd3 Nh6 16.f4 Kd8 17.Bd2 Bd7 18.Rae1 Kc7 19.f5 Nf8 20.Qc4 Kb8 21.Bf4 b5 22.Qc5 Nf7 23.a4 Kb7 24.Qa3 a5 25.axb5 cxb5 26.Nd5 Qd8 27.Bxd6 b4 28.Bxb4 axb4 29.Qxb4+ Kc8 30.Nb6+ Kc7 31.Nxa8+ Qxa8 32.Rf3 Rh6 33.Rc3+ Rc6 34.Rxc6+ Bxc6 35.Qe7+ Nd7 36.Qxf7 Qa5 37.c3 Qa2 38.Qxg7 Qxb2 39.d5 Qxc3 Black resigned, mrjoker - Mandragora, Internet Chess Club, 2009.

13.b3

To deny c4 to the Black Bishop. Also possible was 10.f4. 

13...b6 14.f4 Nf8 

Black has to do something about the threatened fork of his two pieces. Probably he should return the piece with 14...Bf5 15.exf5 Qxe3+ 16. Bxe3 Ne7 getting the Queens off of the board.

15.Qg3

White's threat is e4-e5, and he should probably enforce it directly with 15.Ba3!? and 16.Rae1. He eventually does this, but first he has to address Black harassing his Queen.

15...Nh5 16.Qf3 Nf6 17.e5 Nd5 18.Ba3

The text is okay, although White could have worked to blow things up right away with 18.f5!? Again, he finds the move later.

18...Nxc3 19.Qxc6+ Qd7 20.Qxa8+ Kf7 

White has 3 pawns and a Rook for 2 pieces (one of which he will recover immediately) - as well as an attack on the enemy King. 

21.f5 Ne2+ 22.Kh1 Bxf5 23.Qe4 Ng3+

One of the pieces has to go. Black returns the Knight with a spite check.

24. hxg3 Kg6 25.Qa8

Black resigned

Black's position is a mess, and the closer you look, the worse it appears. The Knight is pinned to the Rook, for example, and the Bishop is pinned to the Knight. The Queen's best move is 25...Qc8, to exchange Queens and get some air, but 26.Qxc8 Bxc8 27.Bxd6 has all the appeal of a root canal.

Jerome Gambit: Miles to Go Before I Sleep

Although SeinfeldFan91 topped the recent Jerome Gambit thematic tournament at RedHotPawn.com without losing (or drawing) a game, it wasn't always easy. The following game shows that, at least once, he had miles to go before he could sleep...

SeinfeldFan91- kristjan
Giuoco Piano Jerome Gambit Tournament
redhotpawn.com 2016

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

4...Kxf7 5.O-O 

White starts off with a "modern" Jerome Gambit line (i.e. lacking 5.Nxe5+) but quickly transposes.

5...Nf6 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6

9.Nc3 Be6 10.f4 Nc6 11.Qa4

According to The Database this is a novelty. More often seen are 11.Qd3 and 11.Qe3.

11...Re8 12.f5 Bd7 13.Qc4+ Kf8 14.Bg5 Qe7 15.Bxf6 Qxf6 16.Rad1 Rac8

White has only a pawn for his sacrificed piece, so he needs to be alert to his opportunities, and keep things complicated.

17.Rf4 Ne5 18.Qd4 Kg8

Completing castling-by-hand.

19.Qxa7

A risky snack, but White's situation, in general, is risky.

19...b6 20.Nd5 Qg5 21.f6 Kh8 22.fxg7+ Kxg7 23.Rdf1 Kh8

Equality comes closer. On little cat feet.

24.Kh1 Nc6 25.Qb7

Risky, but providing a distraction.

25...Na5 26.Qa6 Bc6

27.Rf5 Qh4

Just the break that White was looking for. Much more to the point was 27...Qd2, keeping the game even.

Now White's Knight and Rook target Black's weak h7.

28.Nf6 Bxe4 29.Rh5 Bxg2+ 30.Kxg2 Rg8+ 31.Kh1 Black resigned

Black will have to give up his Queen to avoid mate.
