Jerome Gambit: Risk Upon risk

If it is risky to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), it is even more so to play it at the time control of one minute, no increment. And, to do so - blindfold?

If risky, also exciting, as the latest game from private eye Cliff Hardy shows us. He even shares one of his "secret weapons" in bullet play. Enjoy! [I have added diagrams, but the commentary is by Cliff. - Rick]

Hi Rick!

OK, I'm sorry to inflict this on you again but I like to try playing the Jerome Gambit under different conditions and against different opponents and have included a blindfold bullet Jerome Gambit game I played. Naturally, my opponent would not have played the game blindfolded (well, actually, I guess you never know, but there aren't many of us who are crazy enough to do it, so I rather doubt it ðŸ˜‰). 

Cliff Hardy - NN
1 0 bullet, Lichess, 2020

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Qf6 




10.0-0 N8e7?! =+

Stockfish gives best as 10...Nf4! 11.d3 g5, grabbing space, with a clear advantage for Black, but I admit that it doesn't seem quite so clear an advantage to me.

11.Nc3?! -++

And better here would have been 11.d3!, to stop the ...Nf4! move from being playable again.

11...c6? +=

11...Nf4!

12.d4 Kf7 13.f4 Rf8 14.f5 Nh4?! +-


14...Kg8! += would have left the knight on g6 immune from capture, due to mate on f1.

15.Qd3 

I missed that I could have trapped the knight here with 15.g3?, though Stockfish says that after that, Black could then have given back the piece advantageously with 15...Nhxf5! 16.exf5 Nxf5, upon which he then would have had a slight edge.

15...Kg8 16.g3? -+

Surprisingly a mistake, for reasons along the line of those given on the previous move. Better would have been to have grabbed space with 16.g4! +-.

16...Nhxf5! 17.exf5 Nxf5? =


17...Bxf5! -++ would have been a more forcing and better way to capture here, as it would have attacked the queen and forced White to have wasted a tempo to save it.

18.Ne4 Qg6?! =

18...Qxd4+! 19.Qxd4 Nxd4 20.Rxf8+ Kxf8 21.Nxd6 Nxc2 -++ was a bit too hard to see under the conditions of a bullet game.

19.Be3 d5 20.Nf2? 

20.Ng5 =+ would have been less defensive.

20...h5?! =+

20...Nxe3 21.Qxe3 Qxc2 -++ would have won a pawn.

21.Rae1 h4 22.Bf4 hxg3 23.Bxg3 



23...Nxg3?? 24.hxg3??

Oops? OK, taking the free queen with 24.Qxg6 would have been rather better. Hopefully if I'd been playing sighted I might have seen that! But hey, at least missing it made it more of an even game! ðŸ˜‰

24...Qxd3? = 

24...Bf5! 25.Qc3 Bxc2 -++ would have won another pawn.

25. cxd3?! =+ 

25.Nxd3 = would have kept a better pawn structure.


25...Bh3?? ++- 

Another oops!

26.Nxh3 Rxf1+ 27.Rxf1 Rf8 28.Rf2 Rxf2 29.Kxf2 Kf7 



30.Ke2 g6 31.Kd2 Kf6 32.Kc1 

I admit that my blindfold bullet games often deteriorate into this sort of thing. I'd forgotten where the pieces were and was just shuffling my king back and forth, aiming for the win on time! Sorry, but that's the advantage of having no shame!

32...Kf5 33.Kd1 Kg4 34.Kd2?? Kxh3 -++


Black's position was now totally winning as his g-pawn was unstoppable, though he now had less than 0.1 of a second left on his clock.

35.Ke1 Kxg3 36.Kd2 Kg2 37.Ke2 and White won on time, still with a good 22.1 seconds left on the clock ðŸ˜‰.


Bye,

A GM Faces the BSJG: Not Quite (Part 1)


Last year, on this blog, I had a lot of fun looking at the idea of a Grandmaster playing or facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), online or over-the-board. You might enjoy bouncing back to "A GM Faces the Jerome Gambit (Part 1 and Part 2) and "Jerome Gambit: More GMs? (Part 1 and Part 2)".

In summary, checking The Database, I found some online games with a GM-level player (2500 or above, according to the site's rating scales), but they featured either computers, human players with a lower FIDE rating, or human players whose FIDE rating I could not confirm.

I was left with 2 online games that matched my criteria: ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org2017 (1-0, 39) and Cliff Hardy - Yasser Quesada Perez, lichess, 1 0, 2019 (0-1, 54).

The other day I started wondering: Did any GMs play or face the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+)? That search would be a different kind of task, as the game would have to feature either a rare example of a GM playing the BSG, or, even less likely, a GM playing the BSJG. But my curiosity was piqued...

A search of The Database did not turn up any games with a player (of either color) rated 2500. In fact, there was only one game with a player rated above 2300 - but it was an interesting enough game. White is rated 2386 on the site. 

ivan767 - SanChess2005
7 2 blitz, lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 


The Blackburne Shilling Gambit.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Ke7 

The surprises continue: Black plays the BSG, White "Jerome-izes" it, Black declines the gambit. (SanChess2005 has played this move at least once before, in a frantic 0 minutes, 1 second increment bullet game - see "Faster Than A Speeding Neuron".)

The Database has 755 games with 4...Ke7, with White scoring 70%.

For some thoughts on the BSJG declined, see "Idées Fixes et Manqués".

5.Bc4

White is happy with the pawn he has won, and with the fact that Black will not be able to castle; so he withdraws his Bishop.

5...Ke8

Black unblocks the d8-h4 diagonal, putting the main tactical theme of the Blackburne Shilling Gambit back into play. I have called this a kind of "Jedi mind trick".

6.Nxe5

White relaxes too soon. He could have remained safely a piece up by playing 6.Nxd4 Qh4 (if 6...exd4, 7.Qh5+) 7.Nf3 Qxe4+ 8.Be2

6...Qg5 

Compare this position with one in the main line of the BSG:





analysis diagram






7.O-O Qxe5 8.c3 

8...Nb5

Retreating the Knight to c6 would maintain Black's piece-for-two-pawns material advantage, although White would be somewhat better after 9.d4, because of his better pawn center and Black's less safe King.

9.d4 Qe7 10.Bxb5 c6 11.Bc4 b5 12.Bb3 Nf6 13.e5 Nd5 14.Nd2 Qg5 

White is better, but he has some work to do.

15.Ne4 Qg6 16.Re1 Bb7 17.Nd6+ Bxd6 18.exd6+ Kd8 19.Bxd5 cxd5 20.Bf4 Rf8 21.Be5 Qf5



22.a4

White wants to open a line for his Rook, and he is not afraid to offer his f2 pawn.

23...Qxf2+ 23.Kh1 Qxb2 24.Rb1 Qxc3 



All of this moving of the Queen is risky - in fact, White now has a checkmate in 11 moves, although it is hard to find in this complicated position, especially in blitz.

25.Rxb5 

Even stronger was 25.Bxg7, because Black's Rook cannot move.

25...Ba6 26.Rc5 

This saves his Rook but lets much of the energy escape from the position. White should go after the enemy Queen, but by playing 26.Rf1 Re8 27.Rf3, not the text. Once the Black Queen is moved away from covering the e1 square, White's Queen can go there - and then on to h5, with checkmate threats.

26...Qd3 27.Qxd3 Bxd3 28.Bxg7 Rf7 



White is a pawn up.

29.Bh6 Bc4 

Instead, after 29...Rf1+ 30.Rxf1 Bxf1 White will have to work for the point. 

30.Bg5+ Black resigned



It is checkmate in 3 more moves.

Jerome Gambit: Merry Christmas!

Image result for free clip art chess christmas


Here is my latest letter from Cliff Hardy - a Jerome Gambit game (time limit: bullet, one minute, no increment - in this game, about a second per move.) with a timely Christmas motif! I have added some diagrams, but the commentary is all his - Rick

Merry Christmas, Rick!

This game intrigued me as Black was unusual in being able to find the excellent 11...Kc6! move in this variation. Unfortunately, he was forced soon after that to become really generous this Christmas, as the presents began to be handed out...

Cliff Hardy (2286) - NN (2532)
1 0, Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ 

If you expect to receive presents, you should give some first!

5...Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 Nf6 


11.d3 Kc6!

Very rare for someone to find this risky-looking but pugnacious move - and in bullet too!

12.Nc3

I'm never quite sure in this variation whether to play c3 or Nc3.

12...d5 13.Bf4 dxe4 14.dxe4 Qe6??


Black gives a Christmas present! 14...Qh5! -++, intending 15.e5+ Qxf3 16.gxf3 Nh5, would have been very strong for him.

15.0-0-0?? =

It's Christmas time and White proves to be very charitable! I didn't realise that 15.e5+ Nd5 ++- doesn't really hang in for Black e.g. 16.0-0-0 Rd8 17.Nxd5 Rxd5 18.c4, when the pinned Black rook will require wrapping paper and a gift tag.

15...a6?? ++- 

You know that moment at Christmas when you graciously refuse a Christmas present but the giver continually thrusts it upon you? A complex game would have arisen after 15...Qg4! 16.Qf1! (threatening checkmate in one with 17.Qb5#) 16...b6 =, when Black's exposed king compensates for White's sacrificed bishop.

16. e5+ Kb6 17. exf6 Qxf6??


Another present for me? Why, thank you! Stockfish rated the position before this move as lost for Black anyway, due to his exposed king, but I admit it all looked very unclear to me! Now though, it was fairly easy to take out the win and the rest of the game was uneventful.
