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.

Yes, The Jerome Gambit Is Playable (Part 1)

Image result for free clip art einstein

Is the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) playable?

I have been answering this question for over a decade - for example, see the early "But - Is this stuff Playable?? (Part I)" - and my response looks like this: in friendly games, in blitz games, in games where you are giving "Jerome Gambit odds" to a weaker player, it is playable.

Some adventurous players have not been content to leave it at that.

Years ago, I learned that English player Pete Banks ("Blackburne" online) was willing to attack with the Jerome Gambit in over-the-board games - risking his rating and the chance of teasing by his peers. See "Meet Jerome", "Jerome Gambit, Over-the-Board" and "The Pete Banks Annotated Collection" for examples.

Bill Wall, an unorthodox openings expert and Jerome Gambit afficianado in the U.S., has played some over-the-board games as well (if my records are correct). See "The Jerome Gam'",  and "Jerome Gambit: A Casual Stroll".

Of course, recently this blog has covered the escapades of Australian chess player Kevin Sheldrick (aka "Cliff Hardy"), including his effort at the 2017 Australian Open. See "Jerome Gambit: Cliff Hardy Revealed!"

It is important to not overlook the Jerome Gambit efforts of Louis Morin, of Canada, however. Anyone who has explored The Database knows that he was an early adopter of the opening, has played a truckload of games, appearing online as MrJoker (and, earlier, as a "guest"). Louis also played the Jerome Gambit at the 2015 Quebec Open. See "The Jerome Gam' again".

All of which brings us to a couple of Jerome Gambit games that Louis played at the 2018 Quebec Open.

Okay, so the Jerome Gambit is playable. But - how do you play it?


Morin, Louis (1900) - Guipi Bopala, Prince Eric (1900)
Quebec Open, Quebec, 2018
40 moves / 90 minutes, then 30 minutes

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




Okay, this looks like the ideal time to unleash the Jerome Gambit. Black is an 11 year old - barely older than this blog. What could he know about Alonzo Wheeler Jerome's pet line?

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8



A wise choice. Black avoids the discomfort associated with 6...Ke6, and ducks the tactical edginess of 6...g6 7.Qxe5. He simply wants to give back a piece and take his King out of the action.

On the other hand, White has over 80 games with this position in The Database. He knows what he is doing.

7.Qxe5 d6 8.Qg3 Nf6

According to The Database, Louis is 12 - 4 - 2 against alternatives.

9.d3 

If you have played your share of Jerome Gambits, or explored games presentd on this blog, chances are that this move gave you a chuckle.

Why? Because sometimes White's strategy becomes a bit psychological - instead of racing ahead in some sort of wild attack, he signals that he will slowly and carefully work with his pawns (see "Jerome Gambit: In Pawns We Trust"). Like I wrote a couple of years ago
Steinitz said that the player with the advantage must attack, or risk losing that advantage. White prepares to face that attack, relying on solid "Jerome pawns" instead of planning an attack of his own with f2-f4.
Of course, if Black wants to protect his advantage, he has to take back the move 6...Kf8.

9...Kf7 10.O-O Rf8 11.c3 Kg8 12.d4 Bb6 13.f3 Qe7 14.Bg5 Qf7 15.Nd2 Bd7 



Black has the advantage of a piece vs two pawns, and his two Bishops are not to be discounted. Still, you can almost hear MrJoker saying "Hit me".

16.b3 a6 17.Kh1 Rae8 18.Rfe1 Be6 19.Rad1 Nh5 20.Qf2 Nf4
21.Qe3 c6 22.Bxf4 Qxf4 23.Qxf4 Rxf4


From a purely "objective" point of view, Black has to be smiling: he has escaped a tricky opening, the Queens are off the board, and there is no White attack in sight. On the other hand: what to do, what to do, what to do...

24.g3 Rff8 25.Kg2 a5 26.h3 Rf7 27.f4 g6 28.Rf1 h5 29.Nf3 Bd8 30.c4 b5

All this "doing nothing" is exhausting, even as White's pawns slowly advance like a pack of zombies. Black can hold back no longer.

31.d5 cxd5 32.cxd5 Bxh3+ 33.Kxh3 Rxe4



Argh. Black has returned his piece for a couple of pawns. He should not be too happy about his Bishop, as White's Knight will find outposts that will make it an equal game.

Jerome Gambit Secrets #9

As a reminder about this series:
If you play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) you know that the best source of information on the opening is this blog. 
If you face the Jerome Gambit, however, the best source of information on defending against the opening is - this blog. 
Across the 10 years that I have shared history, games and analysis, I have done my best to give the lines that give White the greatest opportunities to snatch victory from the jaws of this defeated - er, "refuted" - opening. 
I have also not shied away from presenting the various refutations, as well. 
Sometimes players have used my suggestions. Sometimes they have not. The "Jerome Gambit Secrets" posts will re-visit suggestions that appear to remain unplayed. Occasionally, they will introduce new suggestions. 


About a decade ago I played a somewhat embarassing Jerome Gambit blitz game, perrypawnpusher - whitepandora, blitz, FICS, 2008 (1-0, 41), that started off normally, but quickly saw a quirky defense by Black.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf6 



Certainly a King retreat is stronger plan.

I think my opponent was not taking my opening seriously, which seemed to be the case with other defenders in the next 11 games with the position, according to The Database. White scores a hefty 92%, even though the computer rates Black as clearly better.

Now, White can play the simple 8.Qxc5, which has a 6-1 record, and which has been chosen by MrJoker, Bill Wall and me (4 times).

White can also advance his d-pawn, which I will get to in a moment.

When I first posted my game on this blog, I pointed out that 8.f4!? was probably a better move - the old Jerome Gambit "d4 or f4 dilemma" again. According to Stockfish 9, Black has only an edge after 8...Qf8!? 9.Qf5+ Ke7 10.Qxc5+ Kd8 11.Qxf8+ Nxf8 12.d3.

Of course, in that case the Queens are off the board, and White's attack has disappeared. The chances to worry Black have been reduced, too.

Perhaps that is why there are still no game examples with 8.f4 in The Database. In a blitz game, especially, 8.d4 will be the choice of many Jerome Gambiteers.

8.d4 Bb4+

This is Black's best move, but it is hard not to share the alternative 8...Bxd4?? 9.Bg5#, if only because I missed the checkmate in perrypawnpusher - alvarzr, blitz, FICS, 2014 (1-0, 21).

Of course, another bad move for Black is 8...d6??, which chessfriend MrJoker did find the proper response to, 9.Bg5 checkmate.

Why was everyone having a case of nerves? I think because White's 8th move both threatens a piece and promises destruction at g5.

9.c3 c6??

I also love the automatic 9...Ba5?? 10.Bg5 checkmate, Katsampes,T - Maloney,M, St. Agnes School, St. Paul, Minnesota, 2017.

10.Qg5+ 

Missing, of course, 10.Bg5 checkmate, in a hurry to simply win Black's Queen.

Going back to move 9, Black needed to find 9...Ke7 (no game examples in The Database) Then, after 10.cxb4 Nf6 11.Qg5 Kf7 12.O-O d6 13.Nc3 Re8 would have the piece-for-two-pawns advantage that White often has to work against in the Jerome Gambit.

So - 8.f4 remains a "secret", even if it is "objectively best", and perhaps now you know why.

Also, the attractions of 8.d4 - a quick mate or win of the enemy Queen - are hardly a secret at all.

Jerome Gambit: A Day in the Life

I have shared many games where White plays the notorious Jerome Gambit, patiently musters his forces, waits for the defender to make a mistake - and then pounces. After all, I like the Jerome Gambit, and it is fun to watch players use it and succeed.

Yet, I have not been shy about sharing the many refutations of the opening, as well. A line of play can be both exciting and dangerous for the user.

So, as a bit of balance, here is a three minute game that shows Black has chances, too. ☺ (He should: he is rated +200 above White.)

Readers should follow the links to see more alternative ideas for White.

Chess-For-All - Sveti14
3 0 blitz, lichess.org 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5. Nxe5+ Nxe5 6.Qh5+ Kf8 

The Jerome Variation of the Jerome Gambit, played by Alonzo Wheeler Jerome against David Jaeger in correspondence, 1880.


7.Qxe5 d6 8.Qg3 Nf6 9.Nc3


I was surprised to find only 13 games in The Database with this move, with White scoring only 46%. (Still, that is a bit of a step up from the 42% score for White after his 7th move.)

9...Kf7

Also seen: 9...Nh5 in Wall,B - Ahmadi,S, Chess.com, 2010 (0-1, 59) and 9...Ng4 in perrypawnpusher - klixar, blitz, FICS, 2007  (1-0, 33). 

10.O-O Re8


Black has also done well with 10...Rf8 as in perrypawnpusher - truuf, blitz, FICS, 2011 (0-1, 32) and Wall,B - Guest874250, PlayChess.com, 2014 (0-1, 32). 

11.d3 Kg8


Taking care of business by castling-by-hand.

Also seen: 11...Qe7 as in mrjoker - creeredes, Internet Chess Club,
2008 (0-1, 26) 

12.h3 

Adopting the come-and-get-me strategy that puts the onus on Black to make something out of his material advantage. Sometimes this can be a part of a psychological push by White that unsettles his opponent - but, not today. Perhaps he should have ignored the move and gone ahead with winning the "minor exhange" with 12.Na4.

12...Qe7 13.Kh1 

This reminds me of the quote by the Joker in "The Dark Knight" movie: "Come on. I want you to do it. I want you to do it. Hit meHit me! I want you to hit me!"

13...Qf7 14.Be3 Nh5 15.Qh4 Bb6 




16.Nd5 Nf6 17.Nxb6 axb6 18.a3 d5 19.f3 Be6



20.g4 

Time to try to stir things up a bit.

20...Nd7 21.Bd4 

A move that is easy to understand, but repositioning the Bishop might have been better done by playing 21.Rae1 first, and if  21...c5, then  22.Bd2, eventually coming to c3. This subtle idea is brought to you by Stockfish 8.

21...Rf8 


22.f4 

Impatient - but, remember this is a 3 0 game.

The recommended line by Stockfish 8 would have been hard to work out, even in a slower game, with White finally developing pressure on the Kingside to offset Black's gains on the Queenside: 22.Qg3 c5 23.Bc3 d4 24.Be1 c4 25.f4 Nc5 26.f5 Bd7 27.Rd1 Bb5 28.Rf3 Rac8 29.Bb4 cxd3 30.cxd3 Rfe8 31.Rd2 Qb3 32.Kg2 Nd7 33.Rff2 Rc1 34.Kh2 Ne5 35.f6 Qf7 36.Rf5 gxf6 37.g5 Qg7 and Black would still be better. 

22...dxe4 23.dxe4 Bc4 24.Rf2 Rae8 25.Re1 Rxe4 26.Rxe4 Bd5



The a8-h1 diagonal is deadly.

27.Rfe2 Re8 28.Be5 Bxe4+ 29.Rxe4 Qd5 



Again.

30.Qe1 Nc5 White resigned



Ouch.

Jerome Gambit: First Blood

The Jerome Gambit has drawn first blood in the third round of the Chess.com Giuoco Piano thematic tournament. The game is not very exciting, however, and so games have been added in the notes to compensate.

Ouch. This kind of thing can happen, even in a slow game. Maybe the real world intruded. Maybe White's opening looked too innocuous to worry about in the early stages.
