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

Jerome Gambit: Another Zombie Attack

Image result for free clip art zombies



Here is the latest game from Cliff Hardy - a 1-minute, no increment, bullet game that has 60 moves. That's an average of 1 second per move, and Cliff not only won the game, he (of course) won it with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

The commentary is Cliff's. I have added a few diagrams. Have fun!

Hi Rick!

I'm sorry to be so shameless to inflict this 1 0 game on you but the Zombie Attack I got with my pawns in the game was so heart warming ☺. I'm so shameless I even stole the term "Zombie Attack" from your blog! ðŸ˜‰

Cliff Hardy (2212) - NN (2164)
1 0 bullet, Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 Qe7 


9.Qe3 d6 10.Nc3 Nf6 11.0-0 Kf7 12.f4 Rf8 


13.f5 Ne5 14.d4 Nc6 15.Qd3 Kg8 16.Bg5 Qf7 17.Rae1


17...Qh5 18.Bxf6 Rxf6 19.Nd5 Rf7 20.c4 Qg5 21.g3 Qd8 22.g4? =

The zombies are moving! But moving a different zombie with 22.e5! would have yielded White a winning position.

22...Ne7 23.Nf4 Bd7 24.h4 Nc6 25.g5 Rf8 26.a3 Qe8 27.b4 a6


28.Qc3 Qf7 29.a4 

 The zombies have lined up right across the board and are walking (or maybe even dancing?) together down the board like that in the "Thriller" film clip.

29...b5 30.axb5 axb5 31.c5 Na7 32.d5 dxc5 33.bxc5 c6 34.d6 Rae8

35.Qd4 Qc4 36.Qxc4+ bxc4 37.Rf2??



The zombies shouldn't have stopped walking. After 37.e5!? Bxf5 38.e6!, White's zombies on d6 and e6 would have made up for bishop deficit, and led to a slight advantage for White.

37...Nb5??

Crushing for black would have been to take the free pawn with 37...Rxf5!

38.Rc2 Bxf5 39.Rxc4 Be6 40.Nxe6 Rxe6 41.e5 Rd8 42.Rce4 Na7 43.Kf2 Nc8 44.Kf3 Nxd6??


OK, with this Black hangs the knight. Now the standard of the game really goes down the tubes, as we both made a mad rush for the time limit.

45.Kg4?? Nxe4 46.Rxe4 Rxe5?? 47.Rf4?? Rd4?? 48.h5?? Rxc5?? 49.Rxd4

Lol, finally! ðŸ˜ƒ

49...Rc4?? 50.Rxc4 h6 51.Rxc6 Kf7 52.Rc7+ Ke6 53.gxh6 gxh6 54.Rh7 Kf6 55.Rxh6+ Kg7 56.Rg6+ Kh8 57.Kg5 Kh7 58.Rc6 Kh8 59.Kg6 Kg8 60.Rc8 checkmate




I only checkmated with 0.28 seconds left on the clock so it was a bit chaotic for the last quarter of the game! ðŸ˜ƒ

Bye,

Jerome Gambit: If You Stop and Think About It

If you stop and think about it, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a pretty weak opening.

But - what if you didn't have time to stop and think about it?

Or, even better, what if your opponent didn't have time?

Well, then, you might find yourself playing the Jerome in a bullet game, 1 minute / no increment time control.

And, if you were "Cliff Hardy", playing online, you might find yourself defeating an IM.

Just saying.

[Notes by Cliff; diagrams and occasional comments by me - Rick] 

This was a bullet game (1 minute each, no increment) I played against IM Nichita Morozov from Moldova on Lichess. He held a strong position for quite a while but my Jerome pawns maintained great potential and eventually Nichita's desire to eliminate them proved to be a little too strong to resist, leading to his downfall.

Cliff Hardy (2205) - IM Nichita Morozov (2456), Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?! -+


The same inferior defence that IM Rosen played against me long ago - 6...Kf8 -++ or 6...Ke6!? -++ were better choices.

7.Qd5+ 

I had a recent ten minute each game on Lichess where my opponent, rated in the 1700's, resigned at this point as black, for whatever reason!

7...Kf8 8.Qxc5+ Qe7 

 It helps that Cliff has already seen this position, in Hardy - Sevostianov, 1 0 bullet, lichess.org, 2018 (0-1, 56) and Hardy - NN, 1 0 bullet, lichess.org, 2018 (1-0, 20 ) - Rick

9.Qe3 Nf6 10.Nc3 d5!


This liberating move is Stockfish's top choice (though only after it has a long think!) I'm not sure what the stats are on how often this excellent sacrifice is found by players in this position, but I would imagine the overwhelming majority would play the much simpler 10...d6 here.

(The Database has 12 games with the position after White's 10th move; 3 of them, including this one, continue with 10...d5. Three games continue with 10...d6; five continue with 10...c6; one continues with 10...Kf7. - Rick)

11.exd5 Qxe3+?

Here Stockfish likes the deep 11...Kf7!, with the idea of eventually getting the pawn back on d5 e.g. 12.0-0 Rd8 13.Qf3 (or 13.Qd4 c6) 13...Qe5 -+, when White's doomed d5-pawn is surrounded.

12.dxe3?

After 12.fxe3! Bf5 13.d3 +=, White could then have defended his pawn on d5 with the push e3-e4, if found to be necessary.

12...Bf5 

13.Bd2

White couldn't have defended his c-pawn as 13.Kd1? Rd8 would have been too dangerous.

13...Rd8 14.f3 Bxc2 15.Rc1 Bd3 16.e4 Kf7


17.Bg5? -+

17.Na4 =+, threatening Rxc7 or Nc5, would have reduced black's advantage to a minimum.

17...Rhe8 18.Kf2 c6 19.dxc6 bxc6 20.Rhe1 Rd7?!


20...Ne5 -+ would have been better.

21.g4? 

21.Na4, threatening Nc5 again, would have equalised.

21...Rb8? 

21...h6 -++

22.b3?

22.e5!, threatening exf6 or the fork e6+, would have led to a slight advantage for White. Over the next few moves, both players kept missing that this e-pawn push was advantageous for White.

22...c5? 23.h4? 

23.e5! +-

23...c4? 24. bxc4? 

24.e5! =

24...Rb2+?

Simply recapturing with 24...Bxc4 would have been good, since if 24...Bxc4 25.e5 =+, Black's bishop would have prevented White from safely playing the fork e5-e6+.

25.Kg3 Ne5 26.Bxf6? -+

Retaining the bishop with 26.Bf4 += would have been much better, when the passed e-pawn would have created good chances for White.

26...gxf6 27.f4 Nxc4 28.Nd5 Rxa2 29.g5 Ra3 30.Kg4 


30...fxg5? -++

Fine, but 30...f5! would have been a nice sacrifice, when 30.Kh5 (30. Kxf5? Rxd5! -++) 30...fxe4 -++ would have been overwhelming for Black.

31.hxg5 Bxe4??

Black's patience for restraining the potential energy of White's passed Jerome e-pawn ran out and so he eliminated it, but attacking it instead with 31...Nd6 or 31...Nd2, would have retained Black's winning advantage.

32.Rxe4 ++-

Presumably, when Black played 31...Bxe4??, he missed the fact that 32...Rxd5 would be met by a rook capturing on c4. Despite the fact that material was now equal, White's greater central presence and passed Jerome f-pawn surprisingly yielded a winning advantage.

32...Nd6 33.Re5 Rb7 34.Rc6 Ne8 35.Rce6 Ng7 36.Rf6+ Kg8 37.Ne7+

White's advantage now becomes obvious, since 37...Kh8 would have allowed 38.Rf8 checkmate.

37...Rxe7 38.Rxe7 h5+ 39.Kh4?!

39.gxh6 would have been even better.

39...Ra4 40.Rd7 Rb4 41.g6?!


41.Rd8+ Kh7 42.Rh6 mate would have finished off the win neatly.

41...Rb8 42.Rff7 Rf8??

Blundering into a mate, though Black was clearly lost anyway.

43.Rxg7+ Kh8 44.Rh7+

and Black lost on time, before 44...Kg8 45.Rdg7 mate were to happen.

Bye.

Cliff Hardy

P.S. Too bad there are no known examples of world champions playing the Jerome Gambit, as far as I know. I do have copies of games in my records where Magnus Carlsen has beaten high rated opponents on Lichess with the Fred Opening (1.e4 f5) and the Tranvestite Opening (1..c6, 2...Qa5, 3...f6, 4...Qh5, 5...Kd8 and 6...Qe8) so there is some hope that one day he will play the Jerome Gambit against high class opposition.
