Semi-Italian Jerome Gambit: It's Not A Blunder Until It's Refuted

The following blitz game allows me to comment on a rare Jerome Gambit line (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 h6 6.Nxe5+ Nxe5 7.Qh5+ by transposition) and an improvement for Black that has yet to be played, despite its mention here.

Three years ago I wrote in a post "By the Numbers"

The Database has almost 27,000 games in it, yet there are only 7 (until now) with this position; and I had White in all of them, scoring 100%.

The Database now has over 55,000 games, and there are 10 with this position; I had White in all of them, still, scoring 100%.

8.Qxe5

Here Black resigned in perrypawnpusher - JohnBr, blitz, FICS, 2010 and perrypawnpusher - AcesFullofKings, blitz, FICS, 2011.

8...d6

Black tried 8...Nf6 in perrypawnpusher - islanderchess, blitz, FICS, 2008 (1-0, 46), perrypawnpusher - wadada, blitz, FICS, 2009 (1-0, 19) and perrypawnpusher - Entangle, blitz, FICS, 2014 (1-0, 24).

Black played 8...Bd6  in perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 35) and perrypawnpusher - eaadahl, Chess.com, 2013, (1-0, 37).

Black essayed 8...Qf6 in perrypawnpusher - alekbb, blitz, FICS, 2010 (1-0, 47).

Black tried 8...Be7 in perrypawnpusher - PravinMamania, blitz, FICS, 2010 (1-0, 50).

Black's best choice is 8...Bf8, as the Rook is then off-limits - 9.Qxh8? Bg7 10.Qh7 Nf6 and Her Majesty is doomed. White does best with 9.d4, but after 9...d6 10.Qb5 c6 11.Qd3 Black is better.

It is possible that Black's move in the game - and the Rook sacrifice - was prompted by some knowledge of the game Amateur - Blackburne, London, 1885, but the addition of ...h6 and 0-0 in our game makes a big difference.

9.Qxh8 h5 10.Qc3

Quickly extracting the Queen, and unnecessarily so, as safety was no longer an issue. It was wiser to play 10.d4 Bb6 11.Qh7+ Kf8 12.Bh6+ Nxh6 13.Qxh6+ Kf7 and gain some more material.

Still, White is the exchange and a couple of pawns ahead, and plays it safe the rest of the way.

10...Be6 11.d4 Bb6 12.d5 Bd7 13.Qf3+ Nf6 14.Bg5 Bg4 15.Qxf6+ Qxf6 16.Bxf6 Kxf6 

17.Nc3 Bd4 18.h3 Bd7 19.Rad1 Be5 20.f4 Bxc3 21.bxc3 Ke7 22.e5

22...Bb5 23.Rf2 Bc4 24.e6 Bxa2 25.f5 gxf5 26.Rxf5 h4 27.Rf7+ Kd8 28.Rf8+ Ke7 29.Rxa8 

I think Black played on because he was ahead on the clock and I was playing in an uninspiring manner - a reasonable idea, although, in this case, an unsuccessful one.

29...a6 30.Rf1 Bxd5 31.Rh8 Kxe6 32.Re1+ Kd7 33.Rxh4 Kc6 34.c4 Be6 35.Rxe6 b5 36.cxb5+ axb5 37.Rb4 Kc5 38.c3 c6 39.Ree4 d5 40.Rh4 Kd6 41.g4 Ke6 42.g5 Kf5 43.Rhg4 Kg6 44.h4 Kh5 45.Kg2 Kg6 46.Kg3 Kg7 47.Rbf4 Kg6 48.Rf6+ Kg7 49.h5 c5 50.h6+ Kh7 51.Kh4 d4 52.cxd4 c4 53.Rb6 c3 54.Rxb5 c2 55.Rg1 Kg6 56.Rc1 Kh7 57.Rxc2 Black resigned

By the Numbers

While I was finishing up my games in the third round of the Chess.com Italian Game thematic tournament, I received a challenge from another player, and was able to inject some more Jerome-ish fun into my game.

We followed a line that I was familiar with, and although it took an odd turn or two, the result was pleasing.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit. I have played it 51 times, scoring 88%. pblond has two of the three wins against me; the other was an embarassing mouse-slip Queen-loss on move 8.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6

The Database has almost 27,000 games in it, yet there are only 7 (until now) with this position; and I had White in all of them, scoring 100%.

8.Qxe5 

Here Black resigned in perrypawnpusher - JohnBr, blitz, FICS, 2010 and perrypawnpusher - AcesFullofKings, blitz, FICS, 2011.

8...Bd6

Or 8...Qf6 as in perrypawnpusher - alekbb, blitz, FICS, 2010 (1-0, 47); or

8...Be7 as in perrypawnpusher - PravinMamania, blitz, FICS, 2010 (1-0, 50); or

8...Nf6 as in perrypawnpusher - islanderchess, blitz, FICS, 2008 (1-0, 46) and perrypawnpusher - wadada, blitz, FICS, 2009 (1-0, 19)

Best is 8...Bf8!?, planning to trap White's Queen after 9.Qxh8?.

9.Qxh8 Qf6 10.Qxf6+ Nxf6 11.d3 h5 

White has the exchange plus two pawns for the advantage.

I survived the silly 11...Be5 12.Bxh6? in perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 35)

12.Nc3 a6 13.Bg5 Bc5 

The time limit on our game was three days per move, but obviously this was played too casually.

14.Bxf6 Kxf6 15.Nd5+ Kg7 16.Nxc7 Rb8 17.Nd5 d6 

I was pretty sure that if I opened the game up, Black's two Bishops would be a good match for my Rook and Knight. Therefore I took some time to see how I could make use of my extra pawns.

18.c3 Be6 19.Nf4 Bf7 20.d4 Bb6 21.Nh3 Bc4 22.Rfe1 Re8 23.f4 d5 24.e5 Bc7 25.Nf2 a5 26.g3 b6 27.h3 Bd8

I don't think that my timid play impressed my opponent.

28.b3 Bb5 29.Rac1 Bc7 30.c4 dxc4 31.bxc4 Ba6 32.d5 Bc8 

Black is ready to play cat-and-mouse, his Bishops against my pawns, but it is time to open the position and finish things up.

33.d6 Bb8 34.c5 bxc5 35.Rxc5 a4 36.Rb1 Ba7 37.Rc7+ Black resigned

Pssssst... A Tip For Black

Dear Defender,

This is a blog for those interested in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and related openings.

I am sure that you can tell, if you read a few posts, that I like the Jerome, I play the Jerome, and I celebrate Jerome Gambit victories.

If you stick around this blog and look a bit deeper, you will also see that I try to be fair in my evaluations. After all, the Jerome Gambit was practically born refuted.

So, this post is for you, and everyone else who wishes to rain on my parade. Just a little tip...

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

The Semi-Italian Opening, the name given in Euwe and Meiden's Chess Master vs Chess Amateur (1974).

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit, so named because it transposes after the Black King captures the White Bishop to a "modern" variation of the Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 – "classical" Jerome Gambit variations continue with 5.Nxe5+, "modern" Jerome Gambit variations try something else – 5...h6, etc.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6  8.Qxe5

Here, Black resigned. He looks to lose a Rook or a Bishop, remaining with an uneasy King, down a couple of pawns.

But – look closer.

As I pointed out in the notes to my game with alekbb a year ago (and a couple of times before that, going back 3 years) Black is actually better in the final diagram.

The resolute 8...Bf8 ("box" as they say) saves the Black Bishop and poisons the Black Rook: 9.Qxh8? Bg7 10.Qh7 Nf6 and the White Queen is lost.

Zombie Chess

If I am not careful and focused on my play, I tend to play "zombie chess", choosing moves with little thought or analysis, because they "look right" for the position. The result is often a shallow game that misses tactical shots, as if I were just mindlessly shuffling along.

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6

8.Qxe5 Qf6

As I've mentioned, Black's best is 8...Bf8 when after 9.Qg3 (the Rook is poisoned) Ne7 10.d4 Bg7 11.d5 d6 12.Nc3 Rf8 13.Be3 Black has an edge.

Previously seen: 8...Nf6 9.Qxc5 d6 10.Qe3 as in perrypawnpusher - wadada, blitz, FICS, 2009 (1-0,19) and perrypawnpusher - islanderchess, blitz, FICS, 2008 (1-0,46); or.8...Be7 9.Qxh8 Nf6 10.Qxd8 Bxd8 as in perrypawnpusher - PravinMamania, blitz, FICS, 2010 (1-0,50)

9.Qxc5 d6 10.Qd5+  

I could have grabbed a pawn with 10.Qxc7+ instead.

10...Kg7 11.Nc3 Ne7 12.Qc4 c5 13.f4 Be6 14.Qe2 Rhf8 

15.d3 Qd4+ 16.Qe3

Better was 16.Be3, but, typically, I was looking toward a better endgame.

16...Qxe3+ 17.Bxe3 a6 18.Rae1 b5

19.h3 c4 20.d4 b4 21.Ne2 h5 22.c3 b3 23.a3 a5 24.Kh2 a4

Just shuffling along... After all, I have two extra pawns. A simple position means that I will win, in time. Yawn.

25.Ng1 d5 26.e5

Running the risk of a completely blockaded position.

26...Bf5 27.Nf3 Bd3 28.Rf2 Nf5 29.g4

29...Nxe3 30.Rxe3 hxg4 31.hxg4 Rh8+ 32.Kg3 Be4

33.Ng5 Rh1 34.Nxe4 dxe4 35.Rxe4 Rah8

36.Rg2

I was feeling a bit nervous about the Rooks, which I am sure was Black's idea. After the game, Rybka suggested the straight forward 36.f5 gxf5 37.Rxf5 R1h3+ 38.Kf4 Rh2 39.e6.

36...R8h3+ 37.Kf2 Rd3

He had much better with 37...Rxc3, although when the smoke clears, White will still be on top, e.g. 38.e6 Kf8 39.Re2 Rd3 40.f5 g5 41.f6 Ke8 42.d5 Rhh3 43.Re4 c3 44.bxc3 Rdf3+ 45.Kg1 Rxf6 46.Rxa4 Rfh6 47.Rb4 Rh1+ 48.Kf2 Rd1 49.Rxb3 Rxd5 50.Rg3 Rxe6 51.Re3 Rd2+ 52.Kf3 Rxe3 53.Kxe3 Rg2 54.Kf3 Rc2

38.f5 Rd2+

39.Re2 Rd3 40.f6+ Kf7 41.e6+

Triumph (at long last) of the "Jerome pawns."
