Jerome Gambit: The Improved Face Palm Variation?!

Having taken a look at what I called the "Face Palm Variation" of the Jerome Gambit, I wondered if there was an "improved" variation, where White played an early d2-d4, so that his Knight could safely move to g5 with the support of his dark square Bishop.

I quickly recalled the game Wright - Hunn, Arkansas,1874, played about a half year after Alonzo Wheeler Jerome published his first analysis of his gambit in the Dubuque Chess Journal. The game began 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d4 exd4 5.Bxf7+.

The line was referred to as The Macbeth Attack on the Italian language website Sacchi64. It has a relationship to the Italian Gambit, (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d4) as explored by Jude Acers and George S. Laven in their book The Italian Gambit and A Guiding Repertoire for White - 1.e4, (although they were not interested in Bxf7+)  as well as to the Lewis Gambit (1.e4 e5 2.Bc4 Bc5 3.d4) and the Von der Lasa Gambit, (1.e4 e5 2.d4 exd4 3.Bc4 Bc5).

The Database has 1,413 game examples, with White scoring 37%.

Here is a recent game. Beware: the tactics get out of hand, quickly. White (who has almost 700 games in The Database) shows a number of  practical choices to keep the clock at bay.

drumme - RikTheKing
4 0 blitz, FICS, 2020.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.d4 exd4 

A bit stronger, according to Komodo 10, is 5...Bxd4, although the result for White of the 645 games in The Database was only 26%. 

6.Ng5+ 

By playing an early Bxf7+, White has avoided the Sarratt or Vitzthum Attack, although that's not necessarily a good thing.

6...Ke8 7.O-O h6 

Facing a gambit can be scary, and it's natural to want to kick at the attacking piece - but this dismantles Black's defense, rather than helping it.

8.Qh5+ Ke7 9.Qf7+ Kd6 

Black is now at risk for losing a lot of material.

10.Qd5+ 

White is not feeling very greedy, or perhaps in a 4-minute blitz game there wasn't the time (or need) to dig deeper: 10.Bf4+ Ne5 11.Bxe5+ Kxe5 12.Qxg7+ Nf6 (12...Qf6 13.f4+ Kd6 14.e5+) 13.f4+ Kd6 14.Nf7+ Kc6 15.Nxd8+ would have been painful for Black.

10...Ke7 11.Qxc5+

Grabbing the enemy Bishop, but it was stronger to play 11.Qf7+ Kd6 to return to the line given in the note above, 12.Bf4+ etc.

11...d6 

Do I have to do this all over again? 

Didn't I do it right the first time? 

Do I have to do this all over again? 

How many times do I have to make this climb? 

from Long Title: Do I Have to Do This All Over Again? 

12.Qc4 Ne5 

Black could have grabbed the Knight, and hung on: 12...hxg5 13.Bxg5+ Nf6 14.f4 Qg8 15.Qxg8 Rxg8 16.e5 dxe5 17.fxe5 Nxe5 18.Re1 Ke6 19.Bf4 Nfg4

13.Qxd4 Nf6 14.f4 Nc6 15.Qc3 hxg5 16.fxg5 Nxe4 

Well...

At first glance, Black seems to have played himself out of difficulty. Alas, it is actually a checkmate in 9, for White.

17.Qxg7+ Ke6 18.Qg6+ 

Now, interposing a piece will cost Black a piece. There wasn't time to suss out 18.Qf7+ Ke5 19.Nc3 Qg8 20.Bf4+ Kd4 21.Rfd1+ Kc5 22.Be3+ Kb4 23.a3+ Ka5 24.b4+ Ka6 25.Qf1+ Qc4 26.Qxc4+ b5 27.Qxc6 checkmate 

18...Kd5 

19.Nc3+

Again, development makes the most sense when time is short. Instead 19.c4+ Kc5 20. Be3+ Nd4 21.Qxe4 Kb6 22.Bxd4+ c5 23.Bxh8 was crushing. 

19...Nxc3 20.Qd3+ Ke6 

This might have seemed the safest choice, but it was not. 

21.Qxc3 

I am sure that after the game drumme found 21.Qf5+ Ke7 22.Qf7 checkmate 

21...Ne5 22.Qb3+ Kd7 

Black's uncomfortable King and extra piece is slightly outweighed by White's better development and 2 extra pawns. Although the players' fortunes now go up and down, White keeps the pressure on.

23.Bf4 Qe8 24.Rae1 Kd8 25.Qd5 Qc6 26.Qb3 Re8 

Note, for the umpteenth time, Black's light-squared Bishop at home, blocking his Rook. Typical defense-to-the-Jerome-Gambit "sin".

27.g6 Nxg6 28.Bg5+ Ne7 29.Rxe7 Rxe7 30.Bxe7+ Kxe7 31.Qf7+ Kd8 32.Qf6+ Ke8 33.Re1+ Kd7 34.Qe7 checkmate

Jerome Gambit: The Face Palm Variation

I need to spend a moment or two on a Jerome Gambit variation that has been bothering me for almost 20 years. (See "Another Way to Sacrifice the Knight" and "PSA 2.0" for a couple of rants.) A disreputable line in a disreputable opening, it keeps showing up in games. I would like to call it the Face Palm Variation.

SPOKLECHAT - anzali
5 0 blitz, FICS, 2020

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

 4...Kxf7 5.Ng5+

This line does not have a name that I am aware of. It is based on a tactical shot that may be clever, but not convincing. (I gave a warning about a decade ago in the post "Public Service Announcment".)

The Database has 568 games with the line, with White scoring 23%. The earliest games that I have (6 losses) feature TiFoZi, at FICS, in 1999. I will try to message him there, but, according to the site, the last time he visited was October 22, 2001.

I can understand that a Jerome Gambit player might try the line on a lark, especially at blitz or lightning time controls; I noticed Jerome regulars such as COMTIBoy, DragonTail, drumme, HauntedKnight, JKELSEY, majorminor, MyGameUMove, Petasluk, snthor, sTpny, superpippo, Teterow, thmavz, ZahariSokolov, and yorgos, have given it a try.

5...Qxg5 

Of course.

The Database shows that this capture occurred 415 times, that is, in 73% of the games. (White scored 16%.)

6.d4 

The idea: the pawn attacks Black's Bishop, while uncovering an attack on Black's Queen.

One of the reasons that White fares so poorly in this line is that White played this thematic move in less than half of the games where Black had grabbed the Knight. But, why offer the piece unless you had this surprise in store? Another way of offering "Jerome Gambit odds"? Inattention?

One downside of the whole idea is that Stockfish 11 now rates Black's advantage to be about the equivalent of two Rooks and a piece...

6...Bxd4 

Out of 195 games, 16 times Black fell for this "trap". That is not very often (8% of the time after 6.d4; 3% of the games where White plays 5.Ng5+), although, when it did happen, White scored 69%.

In 147 of the games, Black played 6...Qxg2, and White still scored 11%, which is kind of amazing.

For the record, 6...Qxg2 crushes. After 7.Rf1 (best) Qxe4+ (capturing on d4 is fine, too) 8.Be3 (8.Qe2 does not provide any relief: 8...Qxe2+ 9.Kxe2 Nxd4+ 10.Kd1 d6 11.Be3 Bf5 11.Na3 Nf6 is gruesome) Nxd4 9.Nc3 Bb4 10.Qd3 (Stockfish 10 prefers castling-by-hand with 10.Kd2 and 11.Kc1, but, really) Bxc3+ 11.Qxc3 Nxc2+ and that should be convincing enough.

But, in the game we are looking at, Black fell down the well...

7.Bxg5 h6 

Black has 2 pieces for his Queen, and might as well try his luck with 7...Bxb2, going after the enemy Rook. Things can get a little complicated after 8.Na3 Nd4, but 9.0-0 Bxa3 10.f4 puts the heat back on the Black King.

After 7...Bxb2, there is also 8.Qh5+ g6 (8...Kf8 9.Na3 Bxa3 [9...Bxa1 10.Nb5] 10.Qf3+ Ke8 11.Qxa3) 9.Qf3+ Kg7 10.Nc3 Bxa1 11.Nd5 and Black will not be able to hold onto his Rook and two piece compensation for his Queen, e.g. 11...d6 12.Bf6+ Nxf7 13.Qxf6+Kg8 14.Nxc7 and White is not only threatening to win the Rook, he threatens to move the Knight to e8 to aid in checkmate.

Again, back to the game.

8.Qf3+ Nf6 9.Bxf6 gxf6 10.Qh5+ Kg7 

11.Nd2 Bxb2 12.Rb1 Bd4 13.Nf3 Bb6 

Black has secured most of his pieces, but he has left one at risk - his King.   

14.Nh4 d6 

Defense is hopeless. For example, 14...Ne7, 15.Rb3 with the idea of moving over to g3.

15.Qg6+ Kf8 16.Qxf6+ Kg8 17.Ng6 Black resigned

The Rook at h8, and possibly the one at a8 as well, will soon be leaving the board.

Hats off to SPOKLECHAT, who took great risks, but also took advantage of his opportunities.

The Database Upgrade

I recently upgraded The Database with games from the online playing site FICS through August, 2018, bumping the number of games it contains to just above 59,000.

With almost 20 years of games from FICS, I have a pretty good representative sample (not just wins, but losses and draws as well) of how online club players play the kind of openings this blog covers.  

There are Jerome Gambit and Jerome-related games, including:

14,353 games with the Jerome Gambit, proper, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5, 4.Bxf7+ (White scores 46%);

2,614 games with the Italian Four Knights Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ (White scores 38%);

204 games with the Semi-Italian Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Bc5 5.Bxf7+ (White scores 64%);

144 games with the Semi-Italian Four Knights Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Nf6 5.Nc3 Bc5 6.Bxf7+ (White scores 65%); and

6,064 games with the Blackburne Shilling Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ (White scores 56%).

In addition, there are some miscellaneous lines, including 1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 4.Bxf7+ (2,406 games, White scores 72%); 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+ (2,061 games, White scores 40%); and various reversed Jerome-style openings, e.g. 1.e4 e5. Nf3 Bc5 3.Nxe5 Bxf2+.

So, who plays the Jerome Gambit?

The player with the most games in The Database (White and Black) is DragonTail (1,452), although I note that his last game is from 2012. Likewise, kingmaple appears 619 times, but his last game is from 2010. yorgos has 600 games, but his last game is from 2014.

As for "active" players, Bill Wall now leads the pack with 842 games in the Database, followed by perrypawnpusher with 592 games - closely followed by drumme with 553 games and Petasluk with 521. I am sure that there are others not yet on my "radar" (e.g. ZahariSokolov with 331 games and rising quickly).

Jerome Gambit: Explosive

I recently received two Jerome Gambit games from chessfriend shugart, who plays at FICS. We have seen his games here before. 

His willingness to play at lightning time control continues to explode my brain.

One thing that helps in his play is familiarity with the opening, as the notes to the following game will show. (There might even be the chance that he reads this blog, and has picked up a tip or two.)

shugart - NightEagle
lightning, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4

The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7

In what appears to be a quick blitz game, shugart easily dealt with his opponent declining the gift: 4...Ke7 5.Nxd4 exd4 6.Bxg8 Rxg8 7.c3 d3 8.Qf3 h6 9.Qxd3 d6 10.O-O Be6 11.Qe2 Qe8 12.d4 Kd7 13.Qb5+ Kc8 14.Qxe8 checkmate, shugart - snob, blitz, FICS, 2013.

5.Nxe5+

The alternative 5.Nxd4 is a hybrid line that has also been played by Jerome Gambiteers such as drumme, HauntedKnight, JKELSEY and Wall:  5...exd4 6.Qh5+ g6 7.Qd5+ Ke8 8.Qe5+ Ne7 9.Qxh8 d6 10.Qxh7 Qd7 11.O-O Qg4 12.f3 Qg5 13.d3 Qf6 14.Nd2 Be6 15.Nb3 Bg8 16.Qh3 Be6 17.Qg3 Kd7 18.Bg5 Qf7 19.Bxe7 Bxe7 20.Nd2 Rh8 21.Rae1?!

5...Ke8

(5...Ke6 6.Qh5 Nxc2+ 7.Kd1 Nxa1 8.Qf7+ Kxe5 9.f4+ Kd6 10.e5+ Kc6 11.Nc3 b5 12.Qd5+ Kb6 13.Qxb5 checkmate shugart - Manoelo, blitz, FICS, 2013)

Necessary was 6...g6, but shugart has some experience with that, too: 7.Nxg6 hxg6 (7...Nf6 8.Qe5+ Ne6 (8...Be7 9.Nxe7 Qxe7 (9...Nxc2+ 10.Kd1 Qxe7 11.Qxe7+ Kxe7 12.Kxc2 d6 13.d3 Be6 14.Nc3 c6 15.Bg5 Rhg8 16.Bxf6+ Kxf6 17.g3 Raf8 18.f4 Ke7 19.Rae1 Kd7 20.e5 dxe5 21.Rxe5 Bg4 22.Rhe1 Kc8 23.Ne4 h5 24.Nd6+ Kd7 25.Nxb7 Rf7 26.Nc5+ Kc7 27.Re7+ Rxe7 28.Rxe7+ Kb6 29.Ne4 Bf3 30.Kd2 h4 31.Ng5 Bd5 32.gxh4 Bxa2 33.h5 Rh8 34.Rh7 Rf8 35.Ke3 Re8+ 36.Kf3 Bd5+ 37.Kg3 Re2 38.Ne4 Rxb2 39.h6 Rb3 40.Nf2 a5 41.Re7 Bg8 42.h7 Bxh7 43.Rxh7 a4 44.Rh8 Kc5 45.Ra8 a3 46.h4 Kd4 47.h5 Ke3 48.h6 Rb7 49.Rxa3 Rh7 50.Rc3 Kd4 51.Rxc6 Black resigned, shugart - Sutarsa, blitz, FICS, 2013) 10.Qxd4 Nxe4 11.0–0 Rg8 12.d3 c5 13.Qxe4 Qxe4 14.dxe4 Black resigned, shugart - smarcek, blitz, FICS, 2014) 9.Nxh8 Qe7 10.0–0 Qg7 11.f4 Qxh8 12.f5 Bd6 13.Qc3 Nc5 14.e5 Nce4 15.Qd4 c5 16.Qe3 Bxe5 17.d3 Bd4 18.Qxd4 cxd4 19.dxe4 d6 20.Bg5 Bd7 21.Nd2 Qg7 22.h4 h6 23.Bf4 Nh5 24.Bxd6 Ng3 25.Rf3 Bc6 26.Re1 Kd7 27.e5 Rf8 28.f6 Rxf6 White forfeited on time, shugart -Yaman, lightning, FICS, 2014) 8.Qxh8 Ne7 9.Qxd4 c6 10.0–0 d6 11.d3 Bd7 12.Bg5 Qc7 13.f4 c5 14.Qc3 b5 15.Bxe7 Bxe7 16.Qh8+ Bf8 17.Qf6 Be7 18.Qxg6+ Kd8 19.Nc3 Be8 20.Qg4 b4 21.Nd5 Qd7 22.Qxd7+ Bxd7 23.Nxe7 Kxe7 24.h3 Rg8 25.Kh2 Bc6 26.g4 d5 27.e5 Ke6 28.Rae1 d4 29.f5+ Kd5 30.e6 Be8 31.f6 Rf8 32.f7 Bc6 33.e7 Rxf7 34.Rxf7 Kd6 35.e8Q Bxe8 36.Rxe8 Kc6 37.Rxa7 Kd5 38.Rb8 c4 39.Rxb4 cxd3 40.cxd3 Kc5 41.Rb8 Kd5 42.Rb3 Ke6 43.Raa3 Kd5 44.Kg3 Black forfeited on time, shugart - Yaman, lightning, FICS, 2014. 

7.Qf7+ Kd6 8.Qd5+

Okay, okay, hold on a minute...

8...Ke7 9.Qf7+

Acceptable, but unnecessarily time-consuming, is 9.Qxd4, e.g. 9...Nf6 10.O-O d6 11.Nc4 Be6 12.Ne3 Kf7 13.f4 Be7 14.f5 Bd7 15.Nd5 Re8 16.Nxf6 Bxf6 17.Qd5+ Kf8 18.d3 Bc6 19.Qb3 Bd4+ 20.Kh1 Qh4 21.Nd2 Bb6 22.Nf3 Qf6 23.Bd2 Rad8 24.Bg5 Qf7 25.Bxd8 Rxd8 26.Qxf7+ Kxf7 27.a4 a5 28.c3 Bd7 29.b4 axb4 30.cxb4 Be3 31.Ra2 Bc6 32.b5 Bd7 33.Re2 Bb6 34.e5 dxe5 35.Nxe5+ Kg8 36.Nxd7 Rxd7 37.Rd2 Rf7 38.d4 Rd7 39.d5 Rd6 40.g4 Kf7 41.h4 Kf6 42.Kg2 Kf7 43.Kg3 Bc5 44.Kf4 Bb6 45.Ke4 Ba5 46.Kf4 Bxd2+ 47.Kf3 Ba5 48.Rd1 Bb6 White forfeited on time, shugart - Yaman, lightning, FICS, 2015.

That's it.

10...Kc5 11.Qd5+ Kb4 12.c3+ Ka4 13.Qa5 checkmate

Jerome Gambit: Sending Pieces to the Wilderness

In the following game, Bill Wall sends one piece, then another, far from the action - or so it seems. Each returns, only to be traded off - yet they are active in helping win the game. The final position is very interesting.

Wall, Bill - NN
lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qf6 

An unusual defense, but, according to The Database, one faced by other Jerome Gambiteers such as blackburne, chessmanjeff, drumme, HauntedKnight, jfhumphrey, stretto, Teterow, and yorgos. Black, having to lose a piece, decides not to move either, but develops a piece instead.

7. dxc5 Ne7 

Further development. Black also had 7...d6, e.g. 8.O-O dxc5 (8...Be6 9.cxd6 cxd6 10.f4 Ng4 11.f5 Qd4+ 12.Qxd4 Black resigned, Wall,B - Anonymous, lichess.com, 2016) 9.Qd5+ Be6 10.Qxb7 Ne7 11.Qxc7 Rac8 12.Qxa7 Qg6 13.f4 Bh3 14.fxe5+ Ke8 15.Qa4+ Rc6 16.Rf2 Rf8 17.Qa8+ Rc8 18.Qa3 Rxf2 19.Qxh3 Rxc2 20.Na3 Re2 21.Nb5 Kf8 22.Qf3+ Ke8 23.Qxe2 h5 24.Nd6+ Kd7 25.Nxc8 Nxc8 26.Qb5+ Kd8 27.Bg5+ Qxg5 28.Rd1+ Ke7 29.Qd7+ Kf8 30.e6 Qe3+ 31.Kh1 Ne7 32.Qd8 checkmate, Wall,B - NN, lichess.org, 2016 

8.O-O Rf8 9.Nc3 Kg8 

Black has castled-by-hand and has seen to his piece development. What will White do? A hint can be found in an earlier Bill Wall game, with a different defense: 9...c6 10.f4 N5g6 11.Be3 d5 12.cxd6 Ng8 13.d7 Rd8 14.dxc8=Q Raxc8 15.Qh5 Kf8 16.e5 Qf7 17.f5 Nxe5 18.Bc5+ Ne7 19.Qxh7 Qf6 20.Ne4 Qh6 21.Qxh6 gxh6 22.f6 Black resigned, Wall,B - Guest4060198, PlayChess.com, 2013. 

10.f4 N5c6 11.Nb5 a6 12.Nxc7 Rb8 13.c3 Qg6 

It looks like White has sent his one developed piece off on a risky pawn-hunt, but the Knight still has influence on the center, and the first player still has things under control - thanks, in part, to the "Jerome pawns". 

14.f5 Qf6 15.Bf4 Ne5 16.Nd5 Nxd5 17.Qxd5+ Nf7 18.Bxb8 Re8 

White has retrieved (and traded off) his far-flung Knight, and now has a Bishop off in the wilderness (admittedly, it captured a Rook). An interesting comparison can be made between the two Bishops left on the board, as one is actively involved, while the other is a passive observer.

19.Rae1 Kh8 20.e5 Qe7  21.Bd6 Nxd6 

The Bishop, too, is exchanged, but by now White has a powerful, checkmating attack.

 22.f6 gxf6 23.cxd6 Qe6 24.exf6 Black resigned

What a position!

Black can simply take White's Queen with 24...Qxd5, but it will be checkmate in a few moves after 25.Rxe8+ Qg8 26.f7! 

Black's best option is to win two Rooks for his Queen with 24...Qxe1 25.Rxe1 Rxe1+ 26.Kf2 but it is clear that he has no way of dealing with White's advanced pawn, for example 26...Re6 27.Qg5 or 26...Re8 27.f7.
