Chess Games Links


Readers may have noticed that I have added a link to this Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) blog: that of Lars Balzer's Chess Games Links. Here's how he describes his site, recently updated:

Links to chess games (pgn, cbf, cbh, cbv, nic, si3, ...) around the internet which you can download for free!

Opening Reports on the New Year's Database

Using the New Year's Database of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+), and Semi-Italian Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0/4.Nc3/4.d3 Bc5 5.Bxf7+) games, I enlisted ChessBase8 to run a series of Opening Reports. The results were enlightening.
Starting with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, the Report found 6,507 games. White "scored badly" at 44%, while Black scored 56%.

As for Black's replies, 4...Kxf7 was played in 6,124 games, when Black "scored well" with 56%, as compared to scoring "averagely" (46%) with 4...Kf8 and "badly" with 4...Ke7 (30%).

These statistics, like all statistics, should be taken with a grain of salt. Still, it is clear at this point that Black gains nothing (and White loses nothing) by avoiding the capture of the Bishop. Too, if the Opening Report considers 46% to be "average", White's 44% is not far off the mark.

Finally, the Critical Line is given as 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5 Nxe5 6.d4 Bxd4 7.Qxd4 Qe7 where White scores 33%. This is interesting, but Readers know that 6...Qh4+ is the actual critical line, even if it has scored poorly in the database.

I re-ran the Opening Report after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 and was not surprised to find that while 5.Nxe5+ was played in 2,677 games and scored "averagely" with 53%, all other White choices scored "below average" (5.c3 47%;), "badly" (5.b3 43%; 5.d4 40%; 5.0-0 36%;) or "miserably" (5.Qe2 33%; 5.d3 32%; 5.a3 31%; 5.h4 31%; 5.Nc3 27%; 5.c4 25%; 5.Ng5 23%; 5.g3 0%; 5.Ng1 0%) – with the exception of 5.b4, transposing to the Jerome Evans Gambit, where White scored "well" at 67% (in 6 games).

I re-ran the Opening Report on 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+, and noticed that White scored 74% against 5...Ke8; 67% against 5...Ke7; 53% against 5...Nxe5; 45% against 5...Kf8; and 38% against 5...Ke6.

Clearly that last move needs more analysis on behalf of White. 

In general, it still looks like White does best to stick with the Jerome Gambit "book" and that Black takes more risks when he knowingly or unknowingly plays away from "book".

Platypus Perils and Follies

Here's another example of what Gary K. Gifford, editor of the Unorthodox Openings Newsletter,  would call "the Jerome Gamble" (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). The "bet" pays off, but only after some tense – and ridiculous – moments.

perrypawnpusher - Banassi
blitz 2 12, FICS, 2009

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6



If Black is brave – or knowledgeable – enough to play this move, his game has a good chance at a happy ending.

7.Qf5+ Kd6 8.f4 Qh4+



Ah, here is part of the "gamble": does Black know the killing Queen sacrifice, or is he just causing trouble??

9.g3 Nf3+ 

Okay, so far.

10.Kd1 Qe7



Uh, no. That would indicate "brave".


11.e5+

Incredible. Black allows a mate-in-one and White overlooks it!

Waiter! Coffee for my friend and me. None of that de-caf stuff, give me high-test!

11...Kc6



Black misses a chance for complete recovery with 11...Nxe5, since after 12.d4 Kc6 13.fxe5 d5 14.Qd3 Bg4+ he has an edge (and an extra piece).

12.Qe4+ Kb6 13.Qxf3 d6



Black is not distressed with the loss of the advanced Knight (he is still a piece ahead) and, seeing the White King as vulnerable, he works to open lines in the center.

14.Nc3

After the game, Rybka gave a tortuous route to equality: 14.d4 Bxd4 15.Qb3+ Kc6 16.Qa4+ Kc5 17.Na3 Bg4+ 18.Kd2 dxe5 19.Qb5+ Kd6 20.fxe5+ Ke6 21.Qc4+ Kf5 22.c3 Be3+ 23.Kxe3 Qxe5+ 24.Kf2 Re8 25.Rf1 Qe6 26.Kg1+ Kg6 27.Bf4 Whew!





analysis diagram






14...Be6



15.Na4+

There has to be some kind of attack on the King, I thought.

That is true, but the move played should only lead to a draw. Rybka preferred 15.b4 Bxb4 16.a3 c6 17.axb4 and White is better in a tense position.

15...Kb5

This is too cooperative. After 15...Ka6 White can play to split the point with 16.f5 Qf7 17.Nxc5+ dxc5 18.Qa3+ Kb6 19.d4, with the plan for repetition of position.

16.Qxb7+


Now White does have an attack going.

16...Bb6 17.Nxb6 axb6 18.Qxa8



18...dxe5 19.a4+ Kc5 20. d3 exf4


Black continues with his plan to open up the center against the White King. He doesn't have many alternatives.

21. b4+ Kd6 22. Bxf4+ Kd7 23. Qb7 Bg4+ 24. Kc1 Ke8 25. Qa8+


White is ahead two pawns plus the exchange, and has a potential for either opening the a-file for his Rook or creating a protected passed pawn. An endgame is just fine for him.

25...Kf7 26.Qd5+ Kf8 27.Qe4 Qxb4 



A game-ending oversight, but the endgame held nothing but suffering for Black.

28. Qxb4+ Black resigned

Booking Mr. Joker

Continuing my on-line visits to some of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Gemeinde members, I stopped by Louis Morin's ("mrjoker") bookshop website. Interesting. It even has copies of my book (with Riley Sheffield), The Marshall Gambit in the French and Sicilian Defenses...

Hmmm... It also looks like Louis has translated a number of Jeremy Silman's books (from English into French).

I'll mention that Louis has contributed comments and analysis to Grandmaster Boris Alterman's web page, if only forme to be able to mention that The Alterman Gambit Guide White Gambits is due out this month, with The Alterman Gambit Guide Black Gambits due out in March, 2010.

The Jerome Gambit Gemeinde has some interesting members!

Ferocious



In the following game, Gemeinde member Welton Vaz ("Ghandybh") of Brazil shows just how ferocious the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can become when it is treated casually. White's play assumes the style of a hungry, relentless predator.

 
Ghandybh - Noel1942
Chess.com, 2009

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6




The New Year's Database has 823 games with this position: White won 45%, Black won 49%, and 6% were drawn.

7.Qd5+ Ke8 8.Qxc5 d6



Black has his typical advantage against the Jerome Gambit: a piece for two pawns. White, in turn, has something to work with: advancing the "Jerome pawns" against Black's uncastled King.

9.Qe3 Nf6 10.O-O Ne5



This idea is new and designed to be provocative.

11.d4 Neg4 12.Qb3 b6



Black wants to develop his light-squared Bishop, so he first makes his b-pawn safe. He could have chosen a come-and-get-me set-up with 12...Qe7 13.f3 Nh6 14.Nc3 Nf7 with a small advantage.

White decides to open the game.

13.h3 Nh6 14.e5 dxe5



A bit better, although certainly unappealing, was 14...Nfg8.

15.dxe5 Nfg8



White may have a slightly better game here, but he definitely has the more comfortable position.

16.Qf3 Be6 17.Rd1 Qc8 18.Nc3 Ne7 19.Nb5



White's initiative grows with the threat of Qxa8 followed by Nxc7+.

19...Rf8 20. Qxa8 Kf7



Black's "best" was to fall in with his opponent's plans and play 20... Qxa8, when after 21.Nxc7+ Kf7 he will be able to answer 22.Nxa8 with 22...Rxa8

21.Qxc8 Rxc8 22.Bxh6 gxh6 23.Nxa7



White is up an exchange and three pawns. Black's only "hope" is to try an attack on the King.

23...Rg8 24.Kh2 Nf5



25.g4 Ne7 26.Nb5 h5 27.Nxc7 hxg4 28.Rd6



Welton is untroubled by the activity near his King and presses his own attack.

28...Bf5 29.Rf6+ Kg7 30.hxg4 Bg6



31.Rd1 Bxc2 32.Rd7 Black resigned



The Knight is lost, which would leave Black a Rook down.

The Pete Banks Annotated Collection


For readers who have been wondering, "What has Jerome Gambit Gemeinde member Pete Banks / "blackburne" been up to lately?" (besides his recent article "How to Win Without Thinking" in the British Chess Magazine, and his appearances in GM Gary Lane's ChessCafe column and recent book The Greatest Ever Chess Tricks and Traps), I would like to direct you to his web page, The Pete Banks Annotated Collection.

If you play over some of the games, you will see that he often has Bxf7+ on his mind – even against the Sicilian Defense. (No surprise there.)
