Jerome Gambit: Scary

Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can be scary enough that the defender surrenders prematurely. 

Take a look at the following game.

MSMDOIPE - geldi

10 0 Blitz, lichess.org, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Qf6 8.f5+ Black resigned

Odd. What to make of it?

The computer's evauation easily gives Black the advantage of over 4 pawns.

On the other hand The Database shows White scoring 10 - 4.

Pure Jerome Gambit.

Jerome Gambit: On the Trail of the Snipe

Regarding yesterday's post, I have not yet heard back on Reddit about the game that featured "[S]ome kind of reverse Jerome Gambit in the Bishop's in a blitz tie-break in 2004".

I did find a game from the 2004 World Championship Knockout Tournament that was a tie-break game, and was either a Vienna Opening or Bishop Opening by transposition - but it featured 4.Bxf7+, not a ...Bxf2+.

For the time being, let me present the game - featuring an interesting endgame battle between 2 Knights and 2 Bishops.

Ni Hua - Vladimirov, Evgeny Yuryevich

FIDE World Championship Knockout Tournament, 2004

1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4  

Tim Harding, in his Bishop's Opening (1973) wrote

The possibility of 3...Nxe4 was recognized by such early nineteenth century theoreticians as Jaenisch and Staunton, who believed however that White simply got the advantage by 4.Bxf7+, disturbing Black's king position at no material cost. But Morphy was to show that this sort of position is often favourable to the second player (e.g. the famous Meek - Morphy game in the Scotch Gambit) since he is left with central control and the two bishops and can usually perform a slow castling. This lesson was slow to be learned, however, 4.Bxf7+ still being seen some 30-40 years after Morphy's retirement.

Jerome Gambit: Another Snipe Hunt

 

I have a tendency to wander the internet, sometimes finding interesting - but incomplete - tidbits of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) information that tend to drive me to distraction looking for something that often doesn't exist.

For example, at a Reddit chess site the other day I ran into a very innocent question

Just curious but has the Vienna been played in world championship matches in recent years?

A response

In a world championship - only in the FIDE knockout era. There was also a Vienna transposing to some kind of reverse Jerome Gambit in the Bishop's in a blitz tie-break in 2004.

Other than that, highest up in the WC cycle was 1994 Candidates bracket match between Adams and Anand (one game), and Short played in relentlessly against Speelman in 1991 Candidates bracket match. 

In a World Championship proper, only 3 games: Alekhine-Euwe 1935, game 27, Chigorin-Steinitz 1892, game 21 and Steinitz-Zukertort, game 20.

Did you catch that? "[S]ome kind of reverse Jerome Gambit in the Bishop's in a blitz tie-break in 2004"?

Looking at ChessBase's Big Database 2016 I could not find a Bishop's Opening (C23 - C24) from 2004 that featured ...Bxf2+.

I did find a couple dozen Vienna / Three Knights games that started 1.e4 e5 2.Nf3 Nc6 3.Nc3 Bc5 4.Nxe5 Bxf2+ - shades of  Kennedy - Chesbrough, Columbus, 1985 (1-0, 44) - but nothing from a FIDE knockout tournament in 2004.

Of course, I posted a request to see the game, but I have no idea if that will be successful.

Jerome Gambit: Why Would He Play That?

Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) players are familiar with the puzzlement our opening sometimes creates in the minds of defenders - Why did he play that?

Often, that is a good question to ask ourselves, as well. If we can understand Why? someone played a move we can better evaluate and deal with that move.

The following game shows what I mean.

rohanazad - Amarnath_Mishra

10 0 blitz, lichess.org, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6. d4 

6...Bxd4 7.Qxd4 Qf6 

Black places his Queen on f6 in a number of different variations in the Jerome Gambit.

Alonzo Wheeler Jerome faced this move in two of his games, Jerome - Norton, correspondence, 1876 (unfinished) and Jerome - Jaeger, correspondence, 1878 (1-0, 35). Both times he responded with 8.Qd1.

Stockfish 14.1 and Komodo 12.1.1 agree with AWJ.

Why?

(About a decade ago I posted a similar precaution in "Something To Watch Out For".)

8.O-O Nf3+ 9.gxf3 Qxd4 White resigned

Of course, 8.Be3, 8.Qe3, 8.Qd5+ and 8.Qc3 (as well as other prudent moves) work, too.

Jerome Gambit: Wandering Through The Database

 

When I wander through The Database my eyes are often caught by long Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games that end in a draw. There is often a story to go along with the final position. 

Here are a few recent examples.

dontcallmelab - Lemmi_win, bullet, lichess.org, 2021

After 52 moves, White has recovered his sacrificed material and gained some more, but at this point it no longer matters, as his "Jerome pawns" have disappeared; in fact, all of his pawns are gone - he does not have checkmating material, so the game is drawn.

morgado76 - VladimirSlies, 3 0 blitz, lichess.org, 2021

Here Black has battled for 53 moves and can be pleased that he is ahead in material, but it is not enough - again, he does not have checkmating material, so the game is drawn.

MinusCarlsberg - Antarebal, 3 0 blitz, lichess.org, 2021

Black has reason to be optimistic with this position, as he has the "right" Bishop (i.e. it controls the Queening square) to go with his h-pawn and he has a prospective checkmate-in-10 moves. What he doesn't have, however, is any time left on his clock (time is often the attacker's secret weapon in the Jerome Gambit) - still, Whites does not have checkmating material, so the best he can do is claim a draw.

Fragmentation_chess - Jordavco, bullet, lichess.org, 2021

Black has an overwhelming advantage in material, and a pending checkmate in 3, but he is again undone by flag fall. Oh, that tricky Jerome Gambit! Again, White does not have checkmating material, so although he has not reached a win on time, he can still grab the half point.

sharpswords - clbishop, 20 0 blitz, lichess.org, 2021

Finally, it has to be admitted that Jerome Gambit players have a lot of luck. In this game between two 1900+ rated players, the defender may have been a bit too casual in punishing the attacker - his "reward" is a draw by stalemate.

Jerome Gambit: Odds

I plan on playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) in every game with the White pieces in the ongoing "Giuoco Piano" tournament at Chess.com, regardless of the strength of my opponent.

The following game is my second win, and it probably should be considered giving "Jerome Gambit" odds, as I outrated my opponent by quite a bit.

 

perrypawnpusher - Ben_is_not10

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+ g6 7.Qxe5 Qe8 

This is an interesting idea, not fully realized. Black is willing to sacrifice his Rook - see "Jerome Gambit: What About the Rook?" - counting on a strong counter-attack starting with ...Qxe4+.

This is similar to Whistler's defense, where Black plays 7...Qe7, which is more prudent, as it protects his Bishop.

8.Qxc5 

Challenging the defense. Capturing the Rook, instead, would be a mistake that would allow a transposition to Whistler's line - not something that I would recommend, although players have done so and survived:

8.Qxh8?Qxe4+ 

The best move, but others have been played - 

8...Nf6? 9.Qxe8+ Kxe8 10.Nc3 Bd4 11.d3 Bxc3+ 12.bxc3 Ng4 13.O-O d5 14.e5 c6 15.h3 c5 16.hxg4 Bxg4 17.f3 d4 18.fxg4 dxc3 19.e6 c4 20.Rf7 cxd3 21.cxd3 c2 22.Bg5 h6 23.Bxh6 g5 24.Rf8+ Ke7 25.Rxa8 c1=Q+ 26.Rxc1 Kd6 27.Rxa7 Kxe6 28.Bxg5 Ke5 29.Rxb7 Kd4 30.Rb4+ Kxd3 31.Rd1+ Kc3 32.Rdd4 Kc2 33.Rdc4+ Kd1 34.Rb2 Ke1 35.Rc1 checkmate, mwafakalhaswa - jcatinis, lichess.org, 2019;

8...Nf6 

Stockfish 14.1 still recommends the Whistler-like 8...Qxe4+, and gives a line which leaves White with an edge: 9.Kf1 b6 10.Qxc7 Nf6 11.d3 Ba6 12.Nd2 Qd5 13.Qg3 Rhe8 14.h4 Kg8 15.c4 Qe6 16.Kg1 Bb7 17.Ne4 Bxe4 18.dxe4 Qxe4 19.Be3 Ng4 20.Rh3 Nxe3 21.Qxe3 Qxc4 22.Qf3 Qe6. Apparently the computer puts its faith in h4-h5 with the idea of opening the h-file for White's Rook.

The text move leaves allows White to protect his e-pawn, stifle Black's play, and remain up a few pawns.

9.d3 d6 10.Qxc7+ Kf8 

The relatively better move was 10...Qd7 - can you see why? 

11.Qxd6+ 

This move is fine, but it is lazy, as it misses 11.Bh6+ Kg8 12.Qg7 checkmate.

White now exchanges and exchanges.

11...Qe7 12.Qxe7+ Kxe7 13.Bg5 h6 14.Bxf6+ Kxf6 

Being careful should bring home the full point.

15.f4 Re8 16.Nc3 Bd7 17.Nd5+ Kg7 

A slip.

18.Nc7 Rac8 19.Nxe8+ Rxe8 20.O-O Rf8 

21.Rae1 g5 22.f5 Kf6 23.e5+ Kg7 24.g4 h5 25.h3 hxg4 26.hxg4 Rh8 27.Rf2 Bc6

With the delightful threat: 28.e6? Rh1 checkmate.

28.Rh2 Rg8 29.Rh5 Kf7 30.Kf2 Be8 31. Rh7+ Kf8 32.d4 Bg6 

Another slip, but I suspect the game has lost interest for him.

Now simplest play for White involves advancing the pawns.

33.fxg6 Rxg6 34.e6 Ke8 35.e7 Rg8 36.d5 Rg6 37.Rh8+ Kf7 38.e8=Q+ Kg7 39.Re7+ Kf6 40.Qf7 checkmate

Jerome Gambit: Peeking Through the Palm

Yesterday's post was skeptical regarding the "Face palm" variation, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Ng5+.

A look at The Database, however, shows 622 games with the line, so there has to be something attractive about it.

I think that White may be counting on Black responding very quickly in a bullet or blitz game.

5...Qxg5 

Okay... The Database has 455 games with this position, with White scoring 16%/

6.d4 

White attacks both the Bishop and the Queen. What if Black's focus is on the center? Will he deal with the lesser of the two threats?

What do you think? At the right time, against the right opponent, with the right time control - might you give it a try?
