Jerome Gambit: A Complicated Position, A Slip


I have completed a game in the current "Giuoco Piano" tournament at Chess.com. As luck would have it, I was playing a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). Even more luck brought me the full point, as my opponent made a slip in a complicated position. That was unfortunate, as he was doing very well - until he wasn't.

Be sure to check out the notes for additional examples of bad luck.

perrypawnpusher - ycarissan

3 d/move "Giuoco Piano" Chess.com, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 Qh4+ 9.g3 Nf3+ 

Here we have the wild "Nibs" variation, first seen in

an imaginary game presented in the June 1899 issue of the American Chess Magazine. In an article titled "A CHESS SCRAP" by "R.F." it is supposedly an early example of chess-by-telephone – filled with all of the difficulties that came from using a then new and unproven technology.

The computers like the variation, assessing Black's developed pieces as more important than his exposed King.

10.Kf1 

Before this game I was 11 - 3 with this move, as opposed to 6 - 0 with the alternative 10.Kd1.

It is relevant to mention a third King-move alternative, as 10.Ke2 Nd4+ leads to the loss of White's Queen. The Database has 19 games with this misfortune - or with White resigning first - but my favorite has to be a game that does not follow the script: 11.Kd3 Qe7 12.Qd5 checkmate.

10...Nd4 

Ouch.

Instead, Black could have followed perrypawnpusher - Temmo, Jerome Gambit thematic tournament, ChessWorld.net, 2008 (0-1, 43) with 10...Qh6.

Please notice that the retreat 10...Qe7 would be met by 11.Qd5+ checkmate, as in the recent game Matechess1 - akhend15, 3 2 blitz, lichess.org, 2021. The Database has 13 similar mates with White's King on d1, but only one with the King on f1.

As Dan Middlemiss pointed out, Black could also have played 10...Ne7, as in perrypawnpusher - DaniyarManat, Piano Piano tournament, Chess.com, 2020 (1-0, 29).

11.Qd5+ Black resigned


White's Queen has escaped danger, with check, giving time to capture Black's Queen.

Carlsen's Win & Handicap Gambits: The New Chess Opening Fashion



The top GM World Champion Magnus Carlsen (White) in his Game 6 against the top GM Challenger Ian Nepomniachtchi after 1. d4 Nf6 2. Nf3 d5 3. g3 e6 4. Bg2 Be7 5. O-O O-O 6. b3 c5 7. dxc5 Bxc5 8. c4 dxc4 9. Qc2 Qe7  played  10. Nbd2?  -  not only a weak gambit, but also a handicap gambit, in fact. Of course, Black should play here 10...cxb3!, and White's compensation is too little. But the Challenger played 10...Nc6?! instead, after his enough long thinking. The result of this game is "1:0". All these facts can create the new chess opening fashion - to play handicap gambits in very serious GM - GM games.

This new chess fashion can make all modern handicap gambits (including Jerome gambit, its weak deferred and weak related lines) very popular on the grandmaster level too.
Probably, the Challenger doesn't read the blog jeromegambit.blogspot.com , because in his Game 8 (Black) against the World Champion he hasn't thought about opponent's pawn f2. Thus, after 1.e4 e5 2.Nf3 Nf6 3.d4 Nxe4 4.Bd3 d5 5.Nxe5 Nd7 6.Nxd7 Bxd7 (Petrov defence, C43) Mr. Carlsen's 7.Nd2!? can be met by 7...Qh4! AN with ...0-0-0! as a part of the further plan. In any case, I suggest Mr. Nepomniachtchi to start reading this blog, because it can help him on the continuous World Chess Championship 2021 and not only on it!
I thank Mr. Carlsen for his very brave gambits on this World Championship. It maybe, he reads this blog sometimes, it maybe, he has studied a handicap gambit psychology here. In any case, this new chess fashion is an interesting fact, which can lead to a large development of theory of such "psychological" gambits in future.

Jerome Gambit: GM Tisdall's Words Before The World Chess Championship 2021

 


Here we have a recent Grandmaster tweet.

Jonathan Tisdall
@GMjtis
Ah, so the Jerome Gambit isn't something newfangled, it's in the relic closet. Part of my probably luckily neglected early education...

Apparently, it was liked...

Jerome Gambit: Boogyman (Part 3)

 


[continued from the  previous post]


[We continue the analysis by Brian Wall and Tyrin Price of the capture of the Rook in Whistler's defense. My comments in blue - Rick]

9...Qxg2 


Brian Wall --Just to complete the analysis let's take a closer look at 8.Qxh8 Qxe4+ 9.Kd1

Tyrin analyzed 9.Kd1 Qxg2 - for no other reason than to be a complete jerk, let's look at 9...Qg4+ instead. 9...Qg4+ 10.Ke1 (10.f3 Qxg2 11.Re1 [11.Qxh7+ Kf8 12. c3 Qxh1+ 13. Kc2 Qxf3 14. b4 Be7 with an extra piece] 11...Qxf3+ 12.Re2 d5 win [or 12...Nf6 13.d4 d5 14.Bh6 Qxe2+ 15.Kxe2 Bg4+] 10...Qxg2 [10...Nf6 11.d3 {11.d4 Qxd4 12.Bh6 Qxb2 13.Qg7+ Ke6 14.Ke2 Qe5+ leaves Black up a piece (or 14...Qxa1)} 11...Qxg2 12.Rf1 d5 13.Nd2 and among multiple wins the easiest is the retreat 13...Bf8 arresting the Queen {13...b6} {13...b5} {13...Bd6} {13...Bb4} {13...Be7}] 14.c3 Bf5 15.Kd1 Re8 is one typical crush) 11.Qxh7+ (11.Rf1 d5 [11...Qe4+; 11...Nf6 are all good] 11... Kf8! 12.Rf1 Qe4+ (12...d5 13.d3 [13.d4 Bh3 14.Bh6+ Nxh6 15.Qxh6+ Kg8 16.Nd2 Re8+ 17.Kd1 Qg4+ 18.f3 Qe6] 13...Bh3 14.Bh6+ Nxh6 15.Qxh6+ Kg8 16.Kd2 (16.Nd2 Re8+ 17.Kd1 Qg4+ 18.f3 Qe6 (18...Qg1! are killers) 16...Bf8 get away from my g6-pawn so I can take your rook 13.Kd1 Qf3+ 14.Ke1 d5 and against almost anything White can try a c8-bishop move will kill, for example 15.d3 (15.d4 Bg4 16.Bh6+ Nxh6 17.Qxh6+ Kf7 18.Nc3 Re8+ 19.Kd2 Re2+! 20.Kc1 Bf5! 21.Nxe2 Qxe2 22.Qd2 Qxf1+ 23.Qd1 Qxd1+ 24.Kxd1 Bxd4 with a very easy endgame win; 15.Nc3 Bh3  [or 15...Bg4!] 16.d4 Bxd4 [or 16...Re8+ are deadly]; 15.Qxg6 Bg4! [or 15...Bf5] [or 15... Bh3!] 16.Nc3 Re8+ 17.Qxe8+ Kxe8 +12 for Black) 15...Bg4!! (or 15...Bh3!) 16.Bh6+ Nxh6 17.Qxh6+ Kf7 18.Nc3 Re8+ 19.Kd2 Re2+ 20.Kc1 Be3+ 21.fxe3 Qxf1+ 22.Nd1 Qxd1+ is a piece up ending, but 22...Rxh2 is even stronger 

10.Qxh7+ Kf8 11.Re1 d5 

And the threat of Bg4 forces White's hand 

12.c4 Qf3+ 13.Re2 

Now, if 13.Kc2 Bf5+ leads to mate

13... Bg4 14.Nc3 Re8 

and the hammer will fall when Black plays d4    

Brian Wall - Where can I find players willing to play the Jerome Gambit?? The more you look at 8.Qxh8 the more hopeless it is. If I was White I would play a different 8th move and settle for very little compensation rather than making things worse.

[Agreed.]

I don't know if Tyrin's idea is best or new but it certainly works.

[The Moral: Against Whistler's defense 7...Qe7, don't play 8.Qxh8.]

Jerome Gambit: Boogyman (Part 2)

 


[continued from the previous post]


[We continue the analysis by Brian Wall and Tyrin Price of the capture of the Rook in Whistler's defense. My comments in blue - Rick]


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


Tyrin Price -.... White has recklessly thrown away his only developed minor pieces in an unjustifiable attack against the Black King. [There will always be skeptics.☺] Black can afford to burn some wood himself to take the initiative with 

6...g6!

Brian Wall - Old friend IM John Watson and Eric "Mr. Prolific" Schiller mention this as also refuting the Jerome but more complicated. Tyrin Price makes it look easy. Typically, Fritz doesn't like 6...g6 right away because it loses material. 

7.Qxe5 Qe7! 

Black is already winning, here. If White exchanges Queens then he has given up a minor piece for two pawns as his remaining army languishes at home. If White takes the h8 Rook then the tables are turned and *he* falls to a justified attack. 

8.Qxh8

Brian Wall - turns out horribly as Tyrin shows but everything else loses the initiative a piece down, e .g. 8.Qxe7+ Nxe7 9.c3 d5 a no fun way to lose for White - Brian Wall; 8.Qf4+ Kg7 (or 8...Qf6); 8.d4 Qxe5 9.dxe5; 8.f4 d6 9.Qxe7+ Nxe7; 8.Qd5+ Kg7 9.d4 Bb6 Brian Wall I find none of White's 8th move alternatives to 8.Qxh8 remotely appealing. So we march forward... (after so much analysis) ...It is obvious now that taking the rook is suicide and that White must choose a different line on move 8 that gives him 2 pawns plus zero initiative for a piece.

[This article shows the danger of 8.Qxh8. Yes, I am willing to present good ideas on behalf of the defense. See "Jerome Gambit: Escape" for my latest suggestion that White now avoid capturing the Rook. By the way, I am not so glum about 8.Qf4+, but it does not lead immediatly to wild play for White.

8...Qxe4+ 9.Kd1 

9.Kf1 Qh4

Instead of Tyrin's 9...Qh4 which is also good 9...Nf6 leads to a cool position - I like positions where one side has a negative evaluation equal to his material advantage! In other words White is up the exchange and a pawn and should be +3 rather than -3. Black has so many threats like ..b6, ...Ba6+, ...Rxh8, like ...Qd4-f4, ...Qf2 mate, like ...Qxc2, ...b6, ...Ba6+. The huge Black advantage here is mainly due to the Queen positions.    

One of my Chess theories is that taking material is much less appetizing than the Chess public thinks - the time involved, usually by putting pieces on squares we don't want to go to and then trying to bring them back, translates into material down the road.  I discovered on my own, which was later conformed by the writing of Nunn and Watson, that if you send your queen fishing it is sometimes better to stay where you are and try to cause trouble there rather than spend 2 or 3 tempi to fight your way back to the center.

In this position, White can follow neither plan effectively. As you study Chess you will know you are getting better when you sense how good your position is even though you are down material. Anyone can win a pawn and avoid danger - there is not much glory in that.  

So now let's try a few moves after 9.Kf1 Nf6 

10.d3 (10.Qd8 Qf5 [10...Qf4 11.f3 b6 12.Nc3 Qd4 {12...Ba6+} {12...Bb7} {12...Qh4 all easy wins; 10...Qd4 11.Ke2 {11.Ke1 Qe4+ (11...Ng4)} {11...Qxf2+}) 11...b6 (11...Qe5+) (11...Qg4+) (11...Ng4) (11...Qxf2+ all easy wins] [10...b6 11.d3 Qg4 {11...Qd4} {11...Qc6} {11...Ba6 all win comfortably. It's hard to go wrong in these lines. - Wall] [10...Qc4+ 11.Ke1 {11.d3 Qxc2 12.Bd2 Qxd3+ (12...Be7) (12...Qd1+) (12...Qxb2) (12...b6) (12...Bd4) (12...Ne4) (12...Ng4) (12...c6 all win - Wall) 11...b6 (11...b5) (11...Be7) (11...Qe6+) (11...Ng4) (11...Qxc2 all win10...Qd4 11.Be3 Qxb2 12.Bxc5 (12.Bh6 Qxa1 13.Qg7+ Ke6 14.Ke2 Brian Wall - is an amusing position with both Kings on the e-file, unable to castle and under attack. The initiative is everything here! Black's extra piece helps too. Black has multiple wins like 14...Qd4, 14...Qxa2 or 14...Qe5+ among many others.) (12.Bg5 Qxa1) 12...d6 Brian Wall - White is a rook up but Black threatens 13...Bg4 14.Qxa8 Qc1 mate plus 13...Qxa1 and 14...Qxb1+ - Black is having so much fun I don't know if he even has time to pick up the c5-bishop. 13.f3 with multiple wins like dxc5 (or 13...Qxa1 14.Ke2 dxc5) (or 13...b6 14.Qd8 Qxa1) (or 13...b5 14.Qd8 Qxa1) (or 13...Qc1+ 14.Ke2 Qxh1) 14.Qd8 Qc1+ All moves win comfortably and are given in descending order of strength. 

10.Nc3 Qd4 (10...Qf5 wins too - Wall) 11.Ne4 Qxe4 12.d3 Qd4 13.Be3 Qxb2 14.Re1 (14.Bxc5 Qxa1+ 15. Ke2 and now d6 or 15...Qxh1 win easily but 15...Qe5+ is in a class by itself - Wall) 14...Bxe3 15.Rxe3 Qxc2; 15...Qb1+ 16.Re1 Qxc2; 15...Qc1+ 16.Re1 Qxc2 should all win comfortably 

10.b4 and now 10...b6! or 10...Qxc2! are devastating but there are multiple other wins like 10...Bd4, 10...Qd410...Qc4+, 10...Bxf2, 10...Qxb4, 10..Qe5, 10...Qg4 

10.g3 Qh3+ 11.Ke1 Qe6+ 12.Kf1 Nf6 with White's Queen in exile, Black's overwhelming development and material advantage is decisive. Here is a possible continuation: 13.d3 Qf5 14.Bf4 b5  Black's QB on the long, light-square diagonal spells doom for White's royalty. 

What do you think? It looks like a solid refutation of this unsound gambit to me. -Tyrin Price- Brian Wall - Anyone would have to agree. There are many beautiful ideas when Black errs but if you are just looking for a quick refutation, I will add some lines to Tyrin's to make them clearer. 

[Wow. Brian takes over the analysis and the whole thing leaves me breathless. It all reminds me of Tyrin's thought

The Jerome Gambit ... now *that* is coffee house ... fully caffeinated - extra strength (use only as directed for prompt temporary relief of quiet games [if conditions persist seek professional guidance])

Indeed.]
