A GM Faces the Jerome Gambit (Part 1)

Image result for free clip art chess players

How many players of grandmaster strength have faced the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)?

I can think of Joseph Henry Blackburne, author of the notorious 1884 dismantling of the opening.


(Please, let's not revisit the "urban legend" that Alekhine lost to the Jerome. Thank you.)


Of course, if we step outside the main lines and include the Open Italian Four Knights Jerome Gambit (otherwise known as the Noa Gambit, or the Monck Gambit- 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Bxf7+ - then we can add , Charousek, Euwe, Lasker, Marco, Marshall, Tarrasch, Teichmann, and Zukertort, for starters.


For today, let's not go there, either.


Still, I have just learned of a Jerome Gambit, played at bullet speed, online, against a grandmaster.


Let me share some recent exchanges of email with the legendary Australian "Cliff Hardy", player of the white pieces. There will be some move references, but do not let them distract you - I will be presenting the game, with annotations, in due time.

Hi Rick! 
Sorry to inundate you with another game but, after playing the Jerome Gambit for years, I finally got my first chance to play a Jerome Gambit against a GM! It was GM Yasser Quesada Perez, from Cuba.  
Unfortunately, I didn't win ðŸ˜­... 
Because GM Quesada Perez is quite new to Lichess - our game was only his 15th bullet game on the site - his bullet rating on Lichess is comparatively low for his standard of chess (his standard FIDE rating is much higher at 2572) and so I expect it will soon probably go a lot higher than it was at the time of this game.
Of course, I replied quickly
Hi, Cliff, 
Very glad to receive your game against Quesada Perez! 
Certainly provides one answer to the question "How would a GM respond to the Jerome Gambit??" 
Of course, it still leaves unanswered things like "How can you play such a coherent game with 1 second a move thinking time?" 
I have been going over the game, and will try to treat it with both a sense of respect and wonder when I post it on my blog - with you, your opponent, and my good pal, Stockfish 10, playing way over my head, it's a bit of a challenge to make sense of, and then share with readers. But, that's the whole point, I guess. 
[Black's 9th move] gave me a chuckle. It's a novelty, according to The Database, although your game later could transpose into a couple of online games from 2017. I can imagine the GM thinking: The only thing wrong with my position is that White may think he has an attack; so, let's exchange queens, and the rest will work itself out. No need for concrete analysis, especially in a bullet game.
Chances are, similar thinking produced [Black's 6th move]. It would be scary think a GM actually had a refutation to the Jerome Gambit in his repertoire. Most likely he thought (or just reacted) he'd settle for something reasonable, and figure the rest out later. I have seen that kind of thinking in numerous defenses to the Jerome - but the players were not super strong, and the "figuring" was much less effective.Stockfish 10 raises it's eyebrows only at [Black's 17th move], and its recommended followup for White is complicated and not at all clear to me, at least at this point - reaching =/+ in some lines, which has got to be the same as "=" in a bullet game (unless I'm playing, when it would be "-++" )
Nice game. Good to see you taking it to "the man". I mean - why not? I would do the same - although the comment was never truer than, for me, "After 1.e4, White's game is in its final throes". 
Thanks for sharing. 
I hope to learn more, and it'll show up in the blog. 
Rick
And Cliff came back with
Hi Rick! 
I was initially afraid you might not want to see the game, as it was a loss where I never really even got a great position, but I was quite excited to finally get a chance to play a GM with the Jerome. I was also quite glad I didn't botch it by just hanging a queen on move 8 or so ðŸ˜‰. 
Yes, I think he made it all up because he seemed to spend a bit more time on the first few moves. Now that Lichess shows move times, I can see that he took a "whopping" 2.0 seconds to play [his 6th move] 😉 , so it was one of his slowest moves in the game ðŸ˜‰. He spent even longer on [his 9th move]  (2.9 seconds on that move) so I guess he was trying to work out some sort of defence that would work best for him, like you said. Unfortunately, I tried to move too quickly and played [my 10th move] there - although who knows, technically [an alternate 10th move] is not that much better a move anyway... 
Yes, I noticed with the analysis that the computer didn't like [Black's 17th move] - but that was way over my head too! ðŸ˜‰ It was good fun to try against the GM and I will try to remember to throw in [the alternate 10th move] next time [his 9th move] is played. 
Also, it shows how there are so many GM's in the world - there's always some you've never heard of - or, at least, I'd never heard of this guy before this game! 
Bye
Me

Jerome Gambit: Cautious in Bullet?

I wonder if it pays to be cautious in bullet chess. Fending off attacks with your clock ticking down can not be much fun. It's probably more enjoyable to choose a wild opening like the Jerome Gambit, and just hack away.

angelcamina - RafaRofer
1 0 bullet, lichess.org

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6   


The Semi-Italian Opening, according to past world champion Euwe. It is also called the Anti-Fried Liver Defense, I suppose because it keeps a White Knight out of g5, where it plans to sacrifice itself on f7. If Black was planning with 3...h6 to protect f7 in this game, he was sorely disappointed.

4.Nc3 Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit. Compare with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 h6. The pawn move may create more weakness than it is worth.

 5... Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6


When you have a couple of pieces for a couple of pawns, and Stockfish 10 rates you as only +1 pawn, you have to know that your opponent has some serious dynamic potential. That is Black's situation at this point.

8.f4 Nc4 

Hoping to save one of the two hanging pieces, but actually surrendering both. The phlegmatic 8...d6 was the move. 

9. Qf5+ Ke7 10.Qxc5+ Nd6 11.e5 




11... b6 12.exd6+ cxd6 13.Qe3+ Kf7 14.O-O Nf6



White is better (material, development, pawn structure, King safety).

15.d3 Re8 16.Qf3 Kg8

Oversight. A 1 minute, no increment time control is brutal. 

17.Qxa8 Ba6 18.Qxd8 Rxd8 19.Bd2 Bb7 20.Rae1 Ng4 21.h3 Nf6 22.Ne4 Nd5 

23.Bc3 Ne7 24.Nxd6 Bc6 25.Rxe7 Rf8 



26.Rxg7+ Kh8 27.Rxd7+ Kg8 28.Rg7+ Kh8 29.Nf7+ Rxf7 30.Rxf7+ Black resigned

Jerome Gambit: Why We Play "Bad" Openings

The following bullet game (one minute, no increment) was sent to me by Angel Camiña. Please be sure to read the notes. 

Anonymous - Anonymous
1 0 bullet, lichess.org, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

This is referred to as the "Semi-Italian Opening" in Euwe & Meiden's Chess Master vs Chess Amateur (1963). It is a cautious attempt to keep a White piece off of g5, at the risk of wasting some time and possibly weakening the Kingside, if Black should castle there.

4.Nc3 Nd4 

Wow, Black goes from "shy" to "outgoing" in one move. He plays the Blackburne Shilling Gambit, with the addition of Nc3 and ...h6. This may well be effective psychology in a bullet game (surprise your opponent, make him take precious time to figure out a novel position), but it is very risky play, nonetheless: In 20 previous games in The Database, Black scored only 20%

Stockfish 10 rates the first player's position as 3 pawns better at this point.

5.Bxf7+ 

One good surprise deserves another. White gives the "Jerome treatment", creating a sort of "Semi-Italian Blackmar Shilling Jerome Gambit" hybrid.

Why do such a thing? First, White is familiar with Jerome Gambit and Jerome-like themes and tactics (and his opponent may not be). Second, the "proper" response to Black's 4th move, at least as laid out by Stockfish 10, is stylized along BSG lines, and may well not be to the first player's taste. The computer recommends 5.Nxe5 Qg5 (thematic BSG) 6.Bxf7+ Kd8 7.Ng4 Nf6 8.Ne3 Bc5 9.O-O Rf8 10.f4 Qh4 11.b4 Bb6 12.Bg6 d6 13.e5 Bg4 14.Qe1 Qxe1 15.Rxe1 dxe5 16.fxe5 Bh5 17. exf6 Bxg6 18.fxg7 Rg8 19.Na4 Rxg7 20.Bb2 Rd7 where White is up two pawns.

5...Kxf7 6.Nxe5+ Ke8 

Home again - and walking into a checkmate.

The computer humorously recommends 6...Ke6 7.f4 Qh4+ 8.g3 Qh3 9.Nd5 Qg2 10.Qg4+ Kd6 11.Qg6+ Nf6 12.Nc4+ Kc6 13.Ne5+
heading toward a draw by repetition.

White is now rewarded for his bold play.

The Jerome Gambit Treatment - Unbelieveable! (Addendum)



I was pleased to see that The Database contained more than a few games with the attacking (against the Semi-Italian / Philidor Defense) move 6.Bxf7+ mentioned by Max Euwe and Walter Meiden in their 1963 book Chess Master vs Chess Amateur, and covered in the previous post (see "The Jerome Gambit Treatment - Unbelieveable!"). 

When we look a bit further, at 6...Kxf7 7.Nxe5+ Kf6 - the line with Black's best defense - it is reassuring to find two games with Euwe and Meiden's recommended 8.Nd3.


It is interesting that in the first of those games Black performed the prudent retreat of his King to h7 (an idea mentioned in the previous post); and then, from a better position, he benefitted from an oversight by White to score the point.

In the second game, clearly the clock played a factor in the blitz game, as both players tossed the advantage (for White, various checkmates) back and forth before splitting the point, as the notes show.

There are also 3 games in The Database with Stockfish 6's choice, and perhaps the best move, 8.Qf3+!? Alas, none of the attackers were able to discover the recommended 8...Kxe5 9.Qf7!? and although they fought the good fight, only the experienced drumme (457 games in The Database) was able to score - and that was a time forfeit win from a worse position.

The Jerome Gambit Treatment - Unbelieveable!


I stumbled over the following game while looking for a possible recent Semi-Italian Jerome Gambit game example. White faced a Philidor Defense variant and dispatched it quickly.

What I recalled in my notes to move 6 got me chuckling, but what I found in my notes to move 7 sent my mind reeling: The "Jerome treatment" leads to this - Unbelieveable!


Take a look and see.


todotranquilo - SrNoth

blitz, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.d4




Sometimes when I am expecting Black to reply with 3...Bc5, I am met with 3...h6, the Semi-Italian Opening, instead. I usually continue with my development with 4.0-0 and hope for Black to fall in with my wishes. Occasionally I see 4...Nf6 and have to try 5.Nc3 before I see 5...Bc5 (and am then able to play 6.Bxf7+).


The earlier series on this blog, "A Jerome Look At The Semi-Italian Opening (Parts 1, 2, 3, 4 5 and 6)", is well worth visiting for history, analysis and games.


I took a quick look at The Database, and noticed:


There are 1,569 games with (or transposing to) 4.d4, with White scoring 64%; there are 352 games with 4.0-0, with White scoring 70%; and there are 349 games with 4.Nc3, with White scoring 61%.


4...d6 


The Database showed only 153 games with this move (not the best), with White scoring 70%. The more popular (and stronger) alternative, 4...exd4, appeared in 1,062 games, where White scored 57%.


5.dxe5 dxe5 6.Bxf7+


Of course, the straight-forward 6.Qxd8+ Kxd8 (or 6...Nxd8 7.Nxe5) 7.Bxf7 would win a pawn for White, but todotranquilo prefers to play like Jerome.


(Due to sampling bias, The Database does not have any games with 6.Qxd8+, but a quick look at ChessBase's online database gives 63 games with that move; White scores 86%. The two databases are vastly different, making comparisons dicey, but this peek gives an indication of the validity of 6.Qxd8+.)

Interestingly enough, 6.Bxf7+ was embraced in Chess Master vs Chess Amateur (1963), by Max Euwe and Walter Meiden

White could act even more energetically [than 6.Qxd8+ etc.] by playing 6.Bxf7+ Kxf7 7.Nxe5+, and Black is in great trouble, for (a) 7...Nxe5? 8.Qxd8 or (b) 7...Ke7 8.Ng6+, or (c) 7...Ke8 8.Qh5+ Ke7 9.Ng6+. After (d) 7...Kf6, the continuation is less clear. This does not mean that the sacrifice would be incorrect, since after 8.Nd3, White has two Pawns for a piece and the Black King is badly placed. On the other hand, a safe win of a Pawn as in the other variations, might be preferable.
Stay with me, there is more.

For starters, due to the magic of transpositions, there are 2,025 games in The Database with this position (after 6.Bxf7+), and White scores 41% - a reason, from a practical point of view, that Readers might consider the mundane 6.Qxd8+ over the dashing 6.Bxf7+. (The online ChessBase database has only one game with the position, a win for White.)

Of course, "from a practical point of view" it might also be wise to avoid the Jerome Gambit altogether; but where is the fun in that??

6...Kxf7 7.Nxe5+ Ke8


As mentioned above, 7...Kf6 is probably Black's strongest reply. Surprisingly, after the suggested pragmatic 8.Nd3, Stockfish 6 recommends 8...Kg6 and 9...Kh7 for Black, maintaining that the defense holds, and that the second player would have the advantage!


To be fair, the authors of Chess Master vs Chess Amateur were tidying up an offhand line in an offhand variation, not preparing for a tournament or writing an opening manual. But, what is the best response to 7...Kf6 ?


The best move seems to be 8.Qf3+!?, sacrificing a piece in true Jerome Gambit style! It turns out that anything else other than taking the piece with 8...Kxe5 for Black leads to checkmate. White's best move then is keep-the-enemy-King-in-the-middle 9.Qf7!?






analysis diagram




I gave the crazy position - White has sacrificed two pieces, Black's King is in mortal danger - to Stockfish 6, and here is just a surface view of what it found (the game is even) 9...Nf6 (9...Bb4+ 10.Nc3 Bxc3+ 11.bxc3 Nf6 12.f4+ Kxe4 13.0–0 Qg8 14.Qg6+ Kd5 15.Rd1+ Nd4 16.Rxd4+ Kc6 17.Qd3 Be6 18.f5 Rd8 19.fxe6 Rxd4 20.cxd4 Qxe6 White has an edge) 10.f4+ Kd6 (10...Kxe4 11.Nd2+ Qxd2+ the only move to avoid mate 12.Bxd2) 11.e5+ Nxe5 (11...Kc5 12.Be3+ Nd4 13.Nc3 Bg4 14.h3 White is better) 12.fxe5+ Kc6 13.Qc4+ (13.exf6?

Please. Even that is too much. Is there any wonder why I play 4.0-0 ?

  
8.Qh5+ g6

The line Euwe and Meiden mention, 8...Ke7 9.Ng6+ is clearly good for White, who wins a Rook. They can be forgiven for not having a computer program which would have told them that the alternative 9.Qf7+ would lead to checkmate in a dozen moves.

The Best Jerome Gambit Game of the Year (Part 2)


We continue from the previous post, considering a game that has lept to the top of the heap for Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games this year.


As indicated, Readers are encouraged to dispute my assessment by sending in other great Jerome Gambit games...


Wall, Bill - Guest871838

PlayChess.com, 2014



8.Qxh8 


Of the offer of the Rook with 7...d6, Blackburne wrote in Mr. Blackburne's Games at Chess (1899), "Not to be outdone in generosity." The cost to White of taking the Rook is to have his Queen locked out of the action, at a time when Black's pieces begin to swarm the Kingside.


Blackburne's book also contained the following: "NOTE. I used to call this the Kentucky opening. For a while after its introduction it was greatly favoured by certain players, but they soon grew tired of it."


A resonable explanation of the reference to the "Kentucky opening" has appeared previously in this blog (see "A New Abrahams Jerome Gambit" for a summary). 


As for the "certain players" who "greatly favoured" the Jerome Gambit, it is difficult to identify them by games played, as I have discovered the games of only a dozen or so players (other than Jerome, himself) who played the opening between when it was introduced in 1874 and the publication of Blackburne's book in 1899. Andres Clemente Vazquez, of Mexico, has four games in The Database, while E.B. Lowe, of Great Britain, has three.


Blackburne might well have been referring to authors who included analysis of the Jerome Gambit in their opening books, in which case George H.D. Gossip, of Theory of the Chess Openings (1879) and The Chess Player's Vade Mecum (1891) ; William Cook, of Synopsis of Chess Openings (1882, 1888); E. Freeborough and C. E. Rankin of  Chess Openings Ancient and Modern (1889, 1893, 1896);and Mortimer of The Chess Player's Pocket book And Manual of the Openings (1888 - 1906); are all likely suspects. Certainly, more research is still needed.


8...Qh4


This is Blackburne's counter attack, threatening 9...Qxf2+ 10.Kd1 Bg4 mate.


9.O-O


Munoz and Munoz, in their notes to Amateur - Blackburne, London, 1885, in the Brooklyn Chess Chronicle, suggested "He should have attempted to free his pieces by P to Q4 [d4] before castling." 


The move 9.d4 received a good look in "Updating the Jerome Gambit (Part 1)", including references to L. Elliot Fletcher’s energetic Gambit’s Accepted (1954), an internet article on Amateur - Blackburne (not currently available) by Brazil's Hindemburg Melao, and some musings and analysis from Bruce Pandolfini, in his 1989 Chess Openings: Traps & Zaps !


9...Nf6


The door closes on White's Queen.


10.Qd8


Melao mentioned that Idel Becker, in his Manual de xadrez (1974), attributed the move 10.d4 to Euwe (source not mentioned). Melao was skeptical about the move, giving Black’s counter-attack 10…Bh3 11.gxh3 Rxh8 12.dxc4 Qxh3 13.f3 g5 14.Rf2 g4 15. Bf4 gxf3 16.Bg3 h5 17.Nd2 h4 18.Nf3 Qg4 with advantage for Black. He preferred 10.Qd8 - another suggestion (without further analysis) by Munoz and Munoz in the Brooklyn Chess Chronicle, August 1885, who opined "The only hope he had was 10.Q to Q8 [10.Qd8], thus preventing the deadly  move of Kt to Kt5 [...Ng4]."


Bill Wall mentioned that 10.d3 loses to 10...Bh3 11.Qxa8 Qg4 12.g3 Qf3 as was brutally demonstrated in RevvedUp - Hiarcs 8, 2 12 blitz, 2006 (0-1, 12).


10...Bd7


Most consistent for Black is 10...Bb6, covering the c7 pawn and enforcing the embargo on the Queen. White should return a pawn to free Her Majesty with 11.e5 dxe5 12.Qd3 as in Wall,Bill - Foo,Nathan, Palm Bay, FL, 2010 (1-0, 33).

A Jerome Look At The Semi-Italian Opening (Part 2)


Here is a game that almost speaks for itself on the topic we are discussing.


LaughingHyena - eclipze
standard, FICS, 2007


1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 




The Semi-Italian Opening.


4.d4 


Per Euwe and Meiden.


4...Nxd4 


Ill-advised, and punishable immediately. Even the conservative player should be thinking "Jerrrrrrroooooommmmmme!"


5.Bxf7+ 


This is so much fun, I hate to point out that 5.Nxe5  is probably even stronger, e.g. 5...d5 (5...Nc6 6.Bxf7+ Ke7 7.Ng6+ Kxf7 8.Nxh8+ Ke7 9.Qd5; 5...Ne6 6.Bxe6 dxe6 7.Qxd8+ Kxd8 8.Nxf7+) 6.Qxd4 and White's centralized lead in development is overwhelming.


5...Kxf7 6.Nxe5+ Ke8 


Ending things, but 6...Kf6 7.Qxd4 and 6...Ke6 7.Qxd4 are clearly better for White.


7.Qh5+ Black resigned


It is not hard to work out: 7...g6 (7...Ke7 8.Qf7+ Kd6 9.Nc4+ Kc5 10.Qd5+ Kb4 11.c3+ Ka4 12.Qa5#) 8.Qxg6+ Ke7 9.Qf7+ Kd6 10.Nc4+ Kc5 11.Qd5+ Kb4 12.Bd2+ Ka4 13.Qa5 checkmate
