Peaceful, Not Frenetic

I have been trying for peaceful, not frenetic, Jerome Gambit games, slowly and steadily progressing toward victory. The following game is a good model for me. White gathers "small advantages" and calmly moves toward victory. But then...

Petasluk - krausepeter
blitz, FICS, 2011

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


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


7.f4 g6

Black mixes up defensive systems -- or something. The Database shows 9 wins for White against 0 losses prior to this game. 7...Qf6 or 6...d6 would have been fine for Black.

8.Qxe5+

Here Black resigned in Petasluk - Meshu, FICS. 2011, played about a week earlier.

Superpippo has played, and gotten away with 8.f5+ in Superpippo-vacaboja, FICS, 2002 (1-0, 37) and 8.Qh3+ in Superpippo-ustad, FICS, 2002 (1-0, 34), but those moves are not to be recommended.

8...Kf7 9.Qd5+


There are nudges and then there are nudges... Actually, 9.Qxh8 was a little better, as in Ghandybh-duboak, Chess.com, 2009 (1-0, 16).


9.Qxc5 was also playable, as in grobnic - vallabhan, GameKnot.com, 2004 (1-0, 24).

9...Ke8 10.Qxc5 d6 11.Qd4 Nf6 12.0-0 Qe7


White is a comfortable two pawns up. There is no need for an immediate "bashi-bazouk attack", as calm development will do.

13.Nc3 Rf8 14.d3 c5 15.Qe3 Ng4


If anyone, Black could heed the advice not to attack prematurely.

16.Qf3 h5 17.h3 Ne5 18.Qg3 h4 19.Qe3 Nc6 20.Bd2 Be6 21.Rae1 Kd7

Both sides have developed, and Black's King has found some shelter, but the story remains the same: a comfortable advantage for White.

22.a3 Rg8 23.e5 d5

Black keeps the position closed, but now White has a protected passed pawn. For now the e-pawn is blockaded, but it remains another advantage to be realized in the future.

24.Qf2

Setting his eyes on the Black pawn at h4.

Instead, Rybka 3 recommended for White the involved pawn sacrifice on the Queenside, 24.Nb5 b6 25.c4 hoping to open attacking lines against Black's King.

It's not hard to side with Petasluk's choice. Besides, he is rated higher than his opponent, and might want to let him come up with the "brilliant" ideas.

24...Raf8 25.Nd1

Perhaps White was thinking of following this up with c2-c3 and d3-d4, erecting a center wall?

In any event, danger for him is brewing on the Kingside, and White needs to strike first, as Rybka 3 points out: 25.b4 g5 26.bxc5 gxf4 27.Rb1 Kc8 28.Nb5 Bxh3 29.Nd6+ Kb8 30.Rxb7+ Qxb7 31.Nxb7 Rxg2+ 32.Qxg2 Bxg2 33.Rb1 Bh3 34.Nd6+ Ka8 35.Nb5 a6 36.Nc7+ Ka7 37.Kh2 Bg4 38.Nxd5 Nxe5 39.Bxf4 Nf3+ 40.Kg2 Whew! That's a lot to figure out in a blitz game.

25...g5

This is what Black has been aiming for. Now White has to counter-punch and mix it up; there is no more "peaceful".

26.c4 gxf4 27.Bxf4 Bxh3 28.e6+ Kd8



29.Ne3 Bxg2 30.Nxd5

In the smoke of the battle, White goes astray. Clearly time was short for him, and attacking the enemy Queen is in general a good strategy, but here there was a discovered check to deal with. 

Rybka 3's suggestion lets the air out of the position, almost like each army consuming the other, with a draw as the result: 30.Nxg2 h3 31.Qe3 hxg2 32.Rf2 Qh7 33.Rxg2 Rxg2+ 34.Kxg2 dxc4 35.dxc4 Ke8 36.Bg3 Qc2+ 37.Qe2 Qxe2+ 38.Rxe2 Rg8 39.Kh3 Nd4 40.Re4 Rg6 41.e7 Nf3 42.Bf4 Ng5+ 43.Bxg5 Rxg5.

Both White's steady peaceful build-up and Black's savagery in counter-attacking would thus have been "rewarded".30...Bxd5+ 31.Kh2 Rg2+ 32.Qxg2 Bxg2 33.Kxg2 Rg8+ 34.Kh3 Nd4 35.Be3 Ke8

Here White forfeited on time.

Another Miniature from Brazil


I was pleased to grab another Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game from Welton Vaz's "Chess, Science Fiction and Peace" blog. See also: "Xadrez, Ficção Cientifíca e Paz" and "Teach / Learn"

Ghandybh  - DVBLTTN 
Online Chess, 2009

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


The adventure begins!

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



7.Qf5+

An earlier game of Welton's went 7.f4 g6 8.Qxe5+ Kf7 9.Qxh8 Qh4+ 10.g3 Qh6 11.Qc3 b6 12.d4 Be7 13.Qc4+ Kf8 14.0-0 c5 15.f5 Qe3+ 16.Bxe3 Black resigned, Ghandybh - duboak, Chess.com 2009

7...Kd6 8.f4 g6


Not a common move, and not a good one, either. Refutations look like 8...Qh4+ or 8...Qf6, not just kicking the White Queen in the shins.

9.Qxe5+ Kc6 10.Qxh8

Yes!

In a previous game I went chasing after butterflies, and caught nothing but a half point: 10.Qd5+ Kb6 11.Nc3 c6 12.Na4+ Kc7 13.Qe5+ Bd6 14.Qxh8 Qh4+ 15.g3 Qg4 16.Qxg8 Qf3 17.Rf1 Qxe4+ 18.Kd1 b5 19.Nc3 Qd4 20.Qxh7 Bb4 21.Qxg6 d6 22.Qd3 Bg4+ 23.Ne2 Qxd3 24.cxd3 Re8 25.Re1 c5 26.a3 Ba5 27.b4 cxb4 28.axb4 Bb6 29.Bb2 Bf2 30.d4 Bxe1 31.Kxe1 Rxe2+ 32.Kf1 Rxd2 33.Bc3 Rxh2 34.Rxa7+ Kb6 35.Rf7 Bh3+ 36.Kg1 Rg2+ 37.Kh1 Rxg3 38.Rf6 Rxc3 39.Rxd6+ Kc7 40.Rd5 Kc6 41.Rh5 Bg4 42.Rg5 Bf3+ 43.Kh2 Bd5 44.f5 Rc4 45.Rg6+ Kc7 46.Rg7+ Kd6 47.Rg6+ Kd7 48.Rg7+ Kd6 49.Rg6+ Ke7 50.Rb6 Rxb4 51.Kg3 Rxd4 52.Rxb5 Kf6 53.Kf2 Kxf5 54.Ke3 Re4+ 55.Kd3 Re5 56.Kd4 Re4+ 57.Kxd5 Re5+ 58.Kc4 Rxb5 59.Kxb5 draw, perrypawnpusher - spontex, FICS, 2009

10...Qh4+ 11.g3 Qh3


White's move is more aggressive than duobak's Qh6 (above), because he plans to infiltrate the Kingside with his Queen. The problem is that Black's Kingside will fall apart faster.

12.Qxg8 Qg2 13.Qd5+ Kb6 14.Rf1



If Black's unsafe King isn't his undoing, being a Rook down will eventually finish him off.

14...Qxh2 15.Qb3+ Kc6 16.Na3 d5 17.Qb5+ Black resigned, as he is going to lose another piece (17...Kd6 18.e5+ followed by 19.Qxc5).

Xadrez, Ficção Cientifíca e Paz


Chessfriend Welton Vaz ("Ghandybh" at Chess.com) has tried his hand at the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) after receiving the database of games from the first year of posting on this site (see "Happy Birthday: Twelve months of blog...") – and the result was pleasant; for him, any way (see "Shock and Awe").

If you have a moment, why not stop by his "Chess, Science Fiction and Peace" blog?


Ghandybh - duboak
Chess.com, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

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


7.f4 g6


Black seems to remember something about this opening... Something about maybe a Blackburne game...? Something...?

7...Qf6 or 7...d6 were good ideas; 7...g6 was not.

8.Qxe5+ Kf7 9.Qxh8

A better capture than taking the Bishop, although that won for White, too: 9.Qxc5 d6 10.Qd4 Nf6 11.0-0 b5 12.d3 c5 13.Qc3 Be6 14.f5 gxf5 15.exf5 Bd5 16.Bg5 Rg8 17.Qd2 Qf8 18.Bxf6 Kxf6 19.Nc3 Bc6 20.Rae1 Bxg2 21.Rf2 Bh3+ 22.Kh1 Bxf5 23.Ref1 Rg5 24.Ne4+ Black resigned, grobnic - vallabhan, GameKnot, 2004

9...Qh4+ 10.g3 Qh6 11.Qc3 b6

Black had bad luck on one long diagonal. He hopes to have better luck on the other one.

12.d4 Be7 13.Qc4+ Kf8 14.0-0 c5

White has the better center, better development, and a safer King.

15.f5

15...Qe3+

An illusion, but Black is still doomed after 15...g5, for example: 16.f6 Nxf6 17.Qd5 Rb8 18.Bxg5 and White will crash through.

16.Bxe3 Black resigned
