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.)

"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

Really, The Jerome Gambit Is Playable (Part 1)

Louis Morin's ("MrJoker") second Jerome Gambit game in the recent Quebec Open again fulfills the mission of an effective chess opening - one that allows him to reach a playable middlegame.

He still has to work hard for the full point, succeed in a tricky endgame, and dodge time trouble in the process, but the game is a battle well worth playing over.   

Morin, Louis - Weston, Paul
Quebec Open, 2018
40 moves / 90 minutes, then 30 minutes

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

Often Black adopts this defense on-the-fly, because it makes sense: he saves one piece and lets the other one go, as he will still be a piece ahead. In addition, he keeps his King on the 7th rank, the better to allow him to develop his Rook to f8 or e8.

Sometimes, however, the Knight on g6 is part of a long term plan - and, in this game, the King moves to and stays in the center. That is an interesting contrast to Louis's earlier Jerome Gambit.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 

A standard setup in the 6...Ng6 variation.

Recently I wrote on this blog about Sheldrick, Kevin - Bhat, Vishal
Australian Open, 2017 (1-0, 20)

This position is as old - fittingly - as Charlick - Mann, correspondence, Australia, 1881 (1-0, 72). The Database has 163 games with the position, with White scoring 70%. Mind you, beside this one, only one other game (by Guido de Bouver of Flanders, Belgium) is an over-the-board encounter.

Of course, we can now add Louis' over-the-board game.

According to The Database, he has had this position in over 50 games.

How do you win with the Jerome Gambit? Experience, experience, experience.

10.O-O Ng4

Interesting. This could be a naive harassment of the White Queen, or the start of tactical operations on the Kingside.

11.Qg3 h5

Wow. Weston is following Bhat's line of play from the Australian Open! (He could also be following perrypawnpusher - Riversider, blitz, FICS, 2010 [1-0, 18] - but, come on, seriously?!)

12.d4!?

An improvement - consciously or unconsciously - over "Cliff Hardy's" risky 12.h3?!.

12...h4

Consistent, although 12...Qh4!? would have forced 13.Qxh4 Nxh4 taking the Queens off of the board. However, Black is more interested in developing his attacking chances than snuffing out White's.

13.Qd3 h3 14.g3 Ne7 

15.f3 Nf6 16.c4 c6 17.d5 

Or 17.Nc3.

17...cxd5 18.cxd5 Bd7 19.Nc3 Qb6+ 

Black continues operations with his King in the center.

20.Rf2 a6 21.Be3 Qb4 22.a3 Qb3

An observer who walked by the board at this point would have a hard time realizing that the position came from an opening in which White sacrificed two pieces.

Stockfish 9 now recommends 23.Bf4 Qb6 24.Be3 Qb3 25.Bf4 Qb6, etc. with a draw by repetition of position.

The Jerome Gambit has, again, delivered a "playable middlegame".

Yes, The Jerome Gambit Is Playable (Part 1)

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: "Cliff Hardy" Spectacular

Another "Cliff Hardy" spectacular! A very interesting Jerome Gambit played with a time control of one minute for each player. (That turns out to be 1 or 2 seconds a move.)

Again, I present notes from Kevin, with some information from his email. I have added diagrams. 

I couldn't resist sending you this game in the "Charlick" variation, played in the famous Jerome Gambit game, Charlick-Mann, correspondence, 1881. I am from Adelaide in Australia. Our official chronological State Championship winner board ( http://www.oocities.org/timessquare/5427/ ) starts with "1868-93 H. Charlick 1894 J. Hilton; 1895 W. J. McArthur..." and ends with "2016 Alan Goldsmith" but there is an interesting wordy preface to the "1868-93 H. Charlick" bit:

"Historical Prelude - Henry Charlick (1845-1916) was acknowledged chess champion of S.A. [South Australia] for 25 years, by common consent and by his pre-eminent ability. He confirmed this rank by winning the Australian title in Adelaide in 1887 and by taking second place the next year in Melbourne. State Championship tournaments began in 1894, after the foundation of the S.A.C.A [South Australian Chess Association] in 1892, but Charlick never took part in these contests for the title he had relinquished."

Kevin Sheldrick - NN

1 0, FICS, 2017 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf8

Charlick-Mann, correspondence, 1881, went 7...Ke8, ...1-0, 72.

8.Qxc5+ d6 9.Qe3 Nf6 10.0-0 Bd7?!

Black is now slightly better but Stockfish likes the manoeuvre 10...Kf7!, intending to artificially castle, with a clear advantage for black.

11.f4

Stockfish slightly prefers 11. d4.

11...h6?!

Doesn't do much - 11...Qe8 or 11...c5 are better.

12.d4 Qe7?!

Looks good but 12...Bb5 is better - a few mistakes around here but I guess this is "one minute each" chess 😃.

13.Nc3?!


13.e5! is a little better.


13...Kg8 14.f5 

Now I am equal.

14...Nf8 15.e5 de 16.de Ne8??

16...Rae8! or 16...Ng4 are better, though I am not losing a pawn after 16...Ng4 17.Qg3!, since 17...Nxe5?? loses to 18.f6.

17.Qe4??

17.Nd5! was crushing, with the threat of pushing the f-pawn.

17...Qc5??

17...Bc6 was necessary to keep black in the game, now the Jerome pawns are too strong.

18.Be3 Qc6 19.Qf4

OK, but 19.Nd5! was even stronger.

19...a6 20.e6 Bc8?!

Sacrificing with 20...Nxe6 was better but still losing for black.

21.Bd4 Nd6 22.Qg3?!

22.f6! was killing.

22...Ne8 23.f6 Nxe6 24.f7+ Kh7 25.Qd3+ g6 26.fxe8=Q Rxe8?

26...Qxe8 is better, though 27.Nd5 is still winning for white.

27.Rf7+ Kg8

27...Ng7 would still lead to a quick mate e.g. 28.Rxg7+ Kh8 29.Rxg6+ Kh7 30.Rg7+ Kh8 31.Qh7 mate

28.Qxg6 Ng7 29.Qxg7 mate

Jerome Gambit: Old McDonnell

Kevin Sheldrick ("Cliff Hardy") sends one of his latest Jerome Gambits. He gets into trouble, but he calls upon his creativity and his "Jerome pawns" save him. The comments are mostly Kevin's. I have added a few diagrams and some notes in blue - Rick

Old McDonnell Had a Pawn Storm

A kingside pawn storm features in many Jerome Gambit games, as is clearly evident in the games on this blog. In that vein, I recently played a Jerome Gambit game that reminded me somewhat of a famous position from an old game between two classic masters, Alexander McDonnell and Louis-Charles de La Bourdonnais in London in 1834. These were two of the strongest players in the world at the time and the final position in that game I have heard being referred to as, arguably, the most famous position in chess history.

  

La Bourdonnais, as black, has just played 37...e2, and so McDonnell resigned in a lost position, despite being the player who currently has a queen on the board.

My game: 

dsjkljdkdjkf - beba buba beba542

15 0, instantchess.com, 25/1/17

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Kf8 6.Qh5??

6.Nxc6! would have been better. (See gfdgfd - leleos
InstantChess.com, 2016.)

6...Nxe5 7.Qxe5 d6 8.Qg3 Nf6 9.d3 h5 10.Bg5 Bd4?!

The odd-looking 10...Qd7!, blocking his bishop on c8 but breaking the pin on the knight on f6, was best. (10...Be6 was perrypawnpusher - ulisimbolon, Giuoco Piano Thematic, Chess.com, 2016 [0-1, 22])

11.c3 Be5??

11...Bb6 would still leave black with a clear advantage.

12.f4

Old McDonnell had a bishop!

12...h4 13. Bxh4??

13.Qf3! Bg4 14.Qe3 and white will win the trapped bishop on e5, with a winning position.

13...Nh5!

13...Nh5 was good for a slight advantage for black (saves his bishop on e5) but 13...Nxe4! was slightly better than that again

14.Qf2 Bf6 15.Bxf6 Qxf6 16.0-0 Bd7 17.Nd2 Ke7 18.d4 Raf8 19.f5 Kd8 20.Rae1 Qg5 21.Nf3 Qg4 22.h3 Qg3

23.Qxg3?

23.Re3 would yield an approximately equal position.

23...Nxg3 24.Rf2 Rhg8?

24...Re8, attacking the e-pawn, would lead to a winning advantage for black, whereas after 24...Rhg8?, white has a slight advantage.

25.Kh2 Nh5 26.g4 Nf4 27.Kg3??

E - I - E - I - O! I missed the fork.

27...Nd3 28.e5 Nxe1 29.Nxe1 de 30.de Bc6 31.g5 Kc8 32.Kg4 Rd8 33.h4 Rd1 34.Re2 Rgd8?

 

Black is still better but 34...Bb5! 35.Re3 Rd2, with a powerful rook on the seventh rank, would lead to a really crushing position for black.

35.e6

With a push-push here and a push-push there of my e- and f-pawns, I was hoping to pull off a swindle, though 35. h5! (i.e. everywhere a push-push!), with a four-pawn storm, would give me better chances to fluke a win from my bad position.

35...R8d2 36.Rxd2 Rxd2 37.f6 gf 38.gf Bd5 39.Kf5 Rf2+ 40.Ke5 Bxa2 41.f7 Re2+??

41...Kd8! was actually the only winning move for black here.

42.Kf4

Now white has a winning position!

42...Rf2+ 43.Nf3 Bxe6 44.f8=Q+ Kd7 45.Qg7+ Kd6 46.Qd4+ Bd5 47.Qxf2 c6 48.Qxa7 Bxf3 49.Kxf3 and black resigned.

Take care of your "Jerome pawns" and they will take care of you. Wonderful, Kevin!
