Jerome Gambit: Early Joker


Not too long ago, François Crépault, a French Canadian chessplayer who has tried the Jerome Gambit, sent me three Jerome games played by Louis Morin.

I was quite excited. Playing mostly under the handle "MrJoker", largely blitz games at the Internet Chess Club (ICC), Morin has about 350 Jerome Gambit games in The Database. His communications, games and analysis show up in many places in this blog.

Still, one of the games M. Crépault sent me was one that I had never seen before - an over-the-board Jerome Gambit (he has played at least a half-dozen) in a serious tournament. I think it was his first.

The following game was played a couple of months before this blog began.

Morin, Louis - Piche, Justin
Montreal, Canada, 2008

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.d3 

Ten years later, Morin played 10.0-0 against Weston, a move that may be ever so slightly better, born of experience. In most lines of Jerome Gambit play, White will want to castle, while it is not clear if he will play d2-d3 or d2-d4; and if he wants to play f2-f4, that, too, is done more safely after 0-0.

10...Ng4 

It's never too early to harass White's Queen. The move is not a mistake, but more relevant would be 10...Kf7, planning to castle-by-hand. 

11.Qg5

White is rated significantly above his opponent, and so makes the choice Jerome Gambiteers sometimes do: simplify, and take the pawns against the piece, because in club/amateur games, that can be a lot easier to play.

11...Qxg5 12.Bxg5 h6 13.Bd2 Rf8 14.O-O


White doesn't have much, yet - in fact, Black has a small advantage - but his plan is simple: develop and advance the "Jerome pawns".

14...Nf4 15.Nc3 Be6 16.Rae1

Komodo 10 prefers 16.d4 Bc4 17.Rfd1 Ng6 18.f3 Ng6

16...Kd7 17.b3 

Preparing for d3-d4 without letting an enemy Bishop or Knight come to c4.

17...c5 18.Bxf4 Rxf4 19.Ne2 Rf6 20.h3 Ne5


I think I hear someone in the back seat of the car asking "Are we there yet?"

21.f4 Nc6 22.c3 b5 23.g4 

Aggressive, but 23.d4 cxd4 24.cxd4 might have been better. 

23...a5 

24.Ng3 g6 25.e5 dxe5 26.Ne4



A nice intermezzo move. Probably it is time for d3-d4 next move.

26...Rf7 27.Nxc5+ Ke7 28.Nxe6 Kxe6 29.d4 Raf8



30.Rd1

Letting the tension out of the position. White should have tried 30.c4 bxc4 31.bxc4 Kd7 32.d5 Nb4 33.Rxe5, when he would have 3 pawns for the piece.

30...exd4 31.cxd4 Kd5 32.f5 gxf5 33.Rf4 fxg4 34.Rxg4 Rf4 



35.Rg6 R8f6 36.Rg8 Rxd4 37.Rxd4+ Kxd4 38.Rg3 Rf5 39.Rg6 Rg5+ 40.Rxg5 White resigned

Not many strong players risk ratings and reputation to play the Jerome Gambit over-the-board. Hats off to Louis Morin.

Jerome Gambit: Full of Psychology

Image result for free clip art psychologist


The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), played at club level, is full of psychology. Imagine the chess tyro facing "Jerome's Double Gambit" and immediately bemoaning, "I thought I knew the Italian Game, but this is a line I overlooked!" Even if he realizes that the opening is a bit sketchy, he might still rationalize "It must be good for something; nobody would sacrifice two pieces for nothing!"

Of course, Black has his own psychological ploys, as the following game shows.

alxaraya - raffa
3 0 blitz, FICS, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kf8

The Jerome Gambit declined.

Black reasons, "If White wants me to take the Bishop, I won't take the Bishop!" 

The computers chuckle: Black trades a won game for a lost game.

5.Bxg8 Rxg8 

White's Bishop has disappeared. The first player is a pawn up - perhaps, with a safer King.

6.Nxe5 

White is obviously looking for 6...Nxe5, when 7.d4 would follow.

6...Bxf2+ 

"If sacrificing a Bishop to displace my King is a good idea, maybe I should do the same to you," thinks Black.

There are only two other examples of this move in The Database. 

Of course, either 6...Nxe5 or 6...Qe7 were playable. 

7.Kxf2 Nxe5

8.Rf1 

Looking to castle-by-hand. There was also the wild 8.d4 Qf6+ 9.Ke1 Qh4+ 10.Kd2 Ng4 11.Qf3+ Ke8 12.Rf1 Nf6 13.Nc3 c6 14.Kd3 d6 15.e5 dxe5 16.dxe5 Bg4 17.Qf4 Rd8+ 18.Ke3 Nd5+ 19.Nxd5 Rxd5 20.Qf7+ Kd8 21.Qxg8+ Kc7 22.Qxg7+ Kb6 23.Bd2 Be6 24.Rad1 Qd4+ 25.Kf3 Qh4 26.Be3+ Ka6 27.g3 Qxh2 28.c4 Qh5+ 29.g4 Qh3+ 30.Kf2 Qh2+ 31.Ke1 Qh4+ 32.Bf2 Rxd1+ 33.Kxd1 Qh3 Black resigned, MrJoker - ThePawnSnatcher, Internet Chess Club, 2011

8...Qh4+ 

This move is aggressive, but also falls to the criticism often seen of the Jerome Gambit: Don't bring your Queen out too early! Perhaps Black figured that his opponent would appreciate the idea. 

The defender folded in an earlier game, with 8...Ke7 9.d4 Ng6 10.Bg5+ Black resigned, MrJoker - Macuta, Internet Chess Club, 2011

9.Kg1+ Ke7 

Black's lead in development does not make up for his lost pawn and his unsafe King. 

10.d4 Ng4 11.h3 Nf6 12.e5 Nd5 13.c4 Nb6 


14.b3 

Solid, protecting the c-pawn and opening lines for the Bishop.

If you want an oddball, stronger move, take a look at 14.Rf4!?, attacking Black's misplaced Queen. Of course, 14...Qg3, now, loses Her Majesty to 15.Rg4. White's real idea is revealed after 14...Qh6 15.Re7+! when 15...Kxe7 16.Bxh6 cannot be answered by 16...gxh6 because 17.c5 or 17.Qf3+ would be too strong; while 16.Kg6 Bd2 is just better for White.

14...d6 15.exd6+ Kxd6 16.c5+ Kc6 17.cxb6 Kxb6 


18.Na3 Be6 19.Nc4+ Kc6 20.Ne5+ Kd6 21.Ba3+ c5 22.Bxc5+ Black resigned

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.

Jerome Gambit: Too Fast, Too Furious (Part 1)


I was playing my last game in the first round of the "Let's Play The Italian Game" tournament at Chess.com when, suddenly, two opponents made their moves against me in new games. Apparently, the computer scheduler had decided that I would progress to the second round of play, even if I lost the first round game (I didn't; I won it) - so, there I was, with two second round games.

Somewhat disconcerting, each of my opponents was playing quickly - in fact, one of my games ended after a day of play, rather fast given that the time control was one move per day.

Still, I was willing to move with speed, too, as we were contesting a Jerome Gambit - in a line that I had visited several times before. (Alas, I lost the other 3 games, so no more "next" round for more Jeromes.)

perrypawnpusher - TobiasBrunner
"Let's Play The Italian Game" tournament
Chess.com, 2018 

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ 

Years ago, I labeled this finesse "a nudge". It is as old as Jerome - Brownson, Iowa, US, 1875 (1-0, 28). In a blitz game, it can get Black wondering what White is up to - using up precious time.

7...Ke8 8.Qxc5 d6 9.Qe3 



After the game, I put Stockfish 9 in "blunder check" mode to look at the game. Initially, it liked 9.Qc3 Qg5 10.Qg3 Qxg3 11.hxg3, with Black's advantage less than a pawn. That seems a bit silly to me, White moving his Queen 5 times, only to let it be exchanged.

According to The Database, I have reached the diagrammed position 83 times in my games. I must have learned something about the line.

9...Nf6 10.O-O Kf7 

Black sensibly prepares to mobilize his Rook, and possibly castle-by-hand.

A major alternative is 10...Ng4.The proper response is 11.Qg3!,and this is reminiscent of the series of posts I did a while back on "Jerome Gambit Secrets". A strong and experienced Jerome Gambiteer tried 11.Qe2, instead, and perished quickly: mrjoker - weiran, ICC, 2008 (0-1, 14). Another played 11.Qc3 and needed all of his Houdini-like powers to escape and turn the tables: Wall,B - Guest1660564, PlayChess.com, 2013 (1-0, 32). 

I have played 11.Qg3 with mixed results: perrypawnpusher - lorecai, blitz, FICS, 2011 (1-0, 14), perrypawnpusher - jgknight, blitz, FICS, 2011 (1/2-1/2, 49), perrypawnpusher - FiNLiP, blitz, FICS, 2011 (0-1, 59). For a couple of more modern examples, from stronger players, see Sheldrick,K - Bhat,V, Australian Open, 2017 (1-0, 20) and Morin,L - Weston,P, Quebec Open, 2018 (1-0, 54)

11.f4 Re8 12.f5 

I have been pretty successful with this thematic move (10 - 4 - 1), chasing the Knight, so I was surprised to see, after the game, that Stockfish 9 recommended 12.Qb3+!? instead. The Database has only one game with that move, a win by Black in 25 moves.

12...Ne5 13.d4 

Here, again, the computer prefers 13.Qb3+, followed by 14.d3, which seems to lock the Queen on the Queenside. (There are no game examples in The Database.) As we will see, Stockfish's preference is based on disliking Black's next move.

13...Neg4

Jerome Gambit: Odd Turns (Part 1)







I just finished a Jerome Gambit game in an Italian Game tournament at Chess.com. It took a couple of odd turns - played as well as unplayed.

Then, again, that's the Jerome Gambit for you.

perrypawnpusher - Sarantes
"Let's Play The Italian Game" tournament
Chess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

Jerome's Defense, appearing in his analysis of "Jerome's Double Opening" in the July 1874 issue of the Dubuque Chess Journal, and seen, initially, in Jaeger - Jerome, correspondence, 1880 (1-0, 40).


7.Qxe5 d6 8.Qg3 Nf6 9.d3 Be6 10.O-O Nh5 



Black has a number of choices, as can be seen from some earlier games:

10...Qd7 11.Be3 Bb6 12.Nd2 Ng4 13.Bxb6 axb6 14.h3 Nf6 15.a3 h6 16.f4 Rg8 17.f5 Bf7 18.Qe3 Re8 19.g4 Nd5 20.Qd4 c5 21.Qf2 Nf6 22.b3 b5 23.Qf4 Qc7 24.a4 bxa4 25.Rxa4 b5 26.Ra6 Rd8 27.Rfa1 Ke7 28.Ra7 Black resigned, mrjoker - PhlebasP, Internet Chess Club, 2009;

10...Bf7 11.Be3 Bb6 12.Nd2 Qd7 13.h3 Qb5 14.b3 Re8 15.a4 Qe5 16.Qxe5 Rxe5 17.Bxb6 axb6 18.f4 Re8 19.g4 h6 20.Kg2 Ke7 21.Kg3 Kd7 22.Rae1 Re7 23.c4 Rhe8 24.h4 Nh7 25.Nf3 Kc6 26.Nd4+ Kc5 27.Nf5 Rd7 28.Nxg7 Rg8 29.Nf5 Rg6 30.h5 Rf6 31.d4+ Kb4 32.Rf3 Be6 33.e5 dxe5 34.dxe5 Rxf5 35.gxf5 Bxf5 36.e6 Re7 37.Rfe3 Nf6 38.Re5 Nxh5+ 39.Kh4 Ng7 40.Rxf5 Nxf5+ 41.Kg4 Ng7 42.f5 Ne8 43.Kh5 Kxb3 44.Kxh6 Kxc4 45.Kg6 Kd5 46.Rd1+ Kc6 47.Rc1+ Kd6 48.Rd1+ Kc6 49.Rd8 Nd6 50.Kf6 Rh7 51.e7 Rf7+ 52.Ke6 Rxe7+ 53.Kxe7 Nxf5+ 54.Ke6 Nd6 55.Rd7 Nc4 56.Rh7 Nb2 57.Rh4 b5 58.axb5+ Kxb5 59.Kd7 c5 60.Kc7 b6 61.Rh6 Nc4 62.Rh1 Ka4 63.Ra1+ Kb3 64.Rb1+ Kc2 65.Rb5 Kc3 66.Kc6 Kd4 67.Rb1 Kc3 68.Rxb6 Nxb6 69.Kxc5 Game drawn because neither player has mating material, MrJoker - horatius, Internet Chess Club, 2011

10...Kf7 11.Be3 Bb6 12.Nc3 Rf8 13.f4 Kg8 14.f5 Bxe3+ 15.Qxe3 Bd7 16.h3 a6 17.g4 c6 18.Rae1 b5 19.Kg2 b4 20.Ne2 a5 21.Qf4 Bc8 22.Ng3 Bb7 23.g5 Ne8 24.d4 c5 25.d5 Nc7 26.h4 Ba6 27.Rf2 Nb5 28.Ne2 a4 29.c4 bxc3 30.bxc3 Na3 31.Qc1 Bxe2 32.Rfxe2 Nc4 33.Qf4 Ne5 34.Rb1 Rb8 35.Reb2 Rxb2+ 36.Rxb2 White resigned, MrJoker - rgiblon, Internet Chess Club 2012; 

11.Qf3+ Nf6 

The placement of White's Queen is problematic. On g3 it is vulnerable to attention by Black's Knight. On f3 it can be harassed by Black's Bishop. It tends to keep Black's King on f8, but that is not, necessarily, a bad thing.

12.Be3 Bb6

Another issue in this kind of position: to exchange Bishops or not. It's probably safe to comment on any exchange with "shouldn't have" and on any non-exchange with "should have exchanged".

13.Nc3 

The Knight has a good "present" here, but I wonder if it would have a better "future" at d2.

13...Kg8 14.Qe2 Qd7 15.f4 Bf7 16.Rae1 Re8 


Black has the extra piece (vs 2 pawns) and the two Bishops. He is not even worried about his Rook at h8. 

White has developed his pieces, and has to find a way to use his "Jerome pawns".

17.Qf3 

I have played over many Jerome Gambits by those much stronger than myself. Sometimes patience is the key. 

17...Qg4 18.Qf2 h5 19.Bxb6 axb6 20.b3 


I admit that this is an odd-looking move. I wanted to be able to play d4 without being bothered by ...Bc4. It just didn't seem to be the time for 21.e5 yet.

20...h4 21.Qf3

I did not like Black's developing action along the h-file, and reluctantly agreed that it was time to swap the Queens.

21...Qxf3 22.Rxf3 Nd5 23.Nxd5 Bxd5 24.Rfe3 Bc6 



Looking at the position, it is clear that White will play d4, and maybe even c4 and g4. He is going to need some help, however.

Black has a solid, attacking Bishop on c6, and both Rooks are in good position. Clearly, he is better.

Jerome Gambit: Bad Moves

Some commentators have suggested that Emanuel Lasker would purposely play "bad" moves in order to upset his opponents, making it easier for him to win a game. As someone who plays the Jerome Gambit, I guess I understand that argument.

It is also possible that Lasker won because he understood, better than his opponents, the positions that he played, both "bad" and "good".

The following game has several times when I can not understand what was going on - only that Bill understood the positions better than his opponent, and that was enough to fashion a win. 

Wall, Bill - Guest4919498
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.Qd2 



Okay, I don't get it. I would suggest "mouse slip", but Bill has played the move before. Given that there's about a 500 rating point difference between him and me, I have to give him the benefit of the doubt and continue to try to figure it out.

8...Nf6  

Bill has also faced 8...Be6 9.O-O Nf6, in Wall,B - Guest477, ICC, 2017, (1-0, 25). 

9.Nc3 c6 10.f4 Ng6 11.O-O 



Bill has suggested that here, and the next few moves, he could have played Qd3. This re-positioning suggests that 8.Qd2 might have been a search for novelty, as he had seen the position after 7...d6 in over 70 games.

11...Re8 12.Re1 b5

When you have the advantage, you are obliged to attack, said Wilhelm Steinitz.

So, once again, the Jerome Gambiteer tests the attacking prowess of the defender.

13.a3 Qb6+ 14.Kh1 Ng4 15.h3 Nf2+ 



16.Kh2 d5 17.exd5 

17...Rxe1

Bill points out that 17...Bf5 was stronger.

18.Qxe1 Bd7 

Stockfish 8 gives a mind-numbing, attacking, alternative: 18...Bxh3!? 19.Kg3!? Nd3 (the piece was lost, any way) 20.cxd3 Bf5 21.Qe3 Qd8 22.Kh2!? cxd5 23.Nxb5 Bd7 24.f5 Kg8!? 25.Kg1!? Nh4 26.Nd4 Qf6 27.Bd2 Re8 28.Qf2 Nxf5 29.Bc3 Qg6 30.Nf3 Bb5 31.a4 Ba6 32.Ne5 Qb6 33.d4 Qf6 34.b4 with an even position. Um, sure.

19.Be3 Ng4+ 

Black has to give up his advanced Knight, but at least gets to dent White's pawn structure.

20.hxg4 Qc7 21.Kg3 

The King has to help out on defense.

21...Qd8 

Eyeing h4.

22.Qh1 Qe7 23.Re1 Qf6 

Now Black's game crashes. He had better chances of survival after 23...Kg8 24.dxc6 Bxc6 25.f5 Qe5+ 26.Kh3 Nf4+ 27.Bxf4 Qxf4 but White would still have the advantage.

24.Ne4 Qd8 25.Ng5+ Kf6 26.Bd4+ Black resigned



Black faces checkmate, the quickest of which is 26...Ne5 27.Rxe5 Bxg4 28.Re6+ Kf5 29.Qxh7+ g6 30.Qxg6 checkmate. Ouch!
