Still Further Off The Beaten Path; And Not So Familiar


Image result for free clip art mail
Here's another Jerome Gambit game from shugart, playing at the Free Internet Chess Server (FICS). Unlike the play in the last post (see"A Familiar Line Off The Beaten Path"), this features a novel line that is truly new to White, and quite rare in The Database (it is one of three games).

shugart - bobbybo
FICS, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qh5 



9...Nf6

Black's move is an improvement over the less-challenging 9...N8e7, e.g. 10.O-O Be6 11.f4 Ke8 12.f5 Bf7 13.fxg6 Bxg6 14.Qf3 Qd7 15.Nc3 Kd8 16.d3 Qe6 17.Bg5 Kd7 18.Qe2 Rad8 19.d4 c6 20.d5 cxd5 21.exd5 Qxe2 22.Nxe2 Bxc2 23.Nd4 Bg6 24.Bxe7 Kxe7 25.Rae1+ Kd7 26.Nf5 Bxf5 27.Rxf5 g6 28.Rf7+ Kc8 29.Ree7 a6 30.Rxb7 Rde8 31.Rxh7 Rxh7 32.Rxh7 Re1+ 33.Kf2 Rd1 34.Rh6 Rxd5 35.Rxg6 Kc7 36.h4 Rh5 37.g3 d5 38.Ke3 Re5+ 39.Kd4 Re1 40.g4 Rd1+ 41.Ke3 d4+ 42.Ke2 Rb1 43.b3 Rb2+ 44.Kd3 Rxa2 45.Kxd4 Rd2+ 46.Kc3 Rh2 47.h5 Rh3+ White forfeited on time, Siggus - MetaMidi, FICS, 2006.

10.Qe2

Also improving on the previous 10.Qf3, e.g. Kf7 11.O-O Rf8 12.Qb3+ d5 13.exd5 Qxd5 14.Qxd5+ Nxd5 15.Nc3 Nb4 16.Rb1 Nxc2 17.b3 Bf5 18.Rb2 Nb4 19.a3 Nd3 20.Ra2 c6 21.a4 Rfe8 22.f3 Nxc1 23.Rxc1 Bd3 24.Raa1 Nf4 25.Kf2 Ne2 26.Nxe2 Rxe2+ 27.Kg3 Rae8 28.b4 Rxd2 29.b5 Ree2 30.bxc6 Rxg2+ 31.Kf4 g5+ 32.Ke3 Rge2+ 33.Kd4 bxc6 34.Kc5 Rc2+ 35.Rxc2 Rxc2+ 36.Kb4 c5+ 37.Ka5 Rb2 38.Rc1 c4 39.h3 Rc2 40.Re1 c3 41.Re5 Rb2 42.Rc5 c2 43.Rc7+ Kg6 44.Rc6+ Kh5 45.Rc3 Rb1 46.Rxd3 c1=Q 47.Rd5 Qc7+ 48.Ka6 Qb6 checkmate, indoeinstein - adlkaslad, FICS, 2014 

10...Kf7 11.O-O Re8 12.Nc3 



Curiously, the game has reached a position from the game featured in the previous post, with Black's Queen on d8 (here) instead of e6 (there).

Black's faulty combination now hands the advantage over to White. (He probably overlooked that the capture at move 14 comes with check.) When you are playing against a bad opening, it is easy to see its many faults, real and imagined.

12...Bg4 13.f3 Nxe4 14.fxe4+ Kg8 15.Qxg4 c6



White now settles things down with some exchanges, magnifying his extra piece and pawn.

16.d3 Qb6+ 17.Kh1 Rad8 18.b3 Ne5 19.Qg3 Re6 20.Bf4 Rg6 21.Qf2 Rf8 22.Qxb6 axb6 23.Bxe5 dxe5 24.Rxf8+ Kxf8 25.Rf1+ Ke7

The endgame plays out as expected.

26.g3 Ke6 27.Kg2 b5 28.Nd1 c5 29.Ne3 h5 30.h4 Rh6 31.Rf5 Rh7 32.Rg5 b6 33.Rg6+ Kf7 34.Rxb6 g6 35.Rb7+ Kg8 36.Rxh7 Kxh7 37.Kf3 Kg7 38.g4 Kf6 39.gxh5 gxh5 40.Nf5 Ke6 41.a4 bxa4 42.bxa4 Black resigned

Footnotes to More Exploring


Here are some additions to the previous post, which focused upon a line in the  Abrahams Jerome Gambitthe game ndizvoh - stevebrown, blitz, FICS, 2015.


After 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ g6 5.Qxe5 Bxf2+ 
6.Ke2


the move 6...Nf6 was suggested as an alternative to 6...Qf6,

He also had the move 6...Nf6, which does the same thing, as 7.Kxf2 would then be met with 7...Ng4+, winning White's Queen.

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ g6 5.Qxe5 Bxf2+ 6.Kf1 Nf6 7.Kxf2 Ng4+ 8.Ke2 Nxe5 9.d4 Nc4 10.b3 d5 11.bxc4 Bg4+ 12.Ke3 Qg5+ 13.Kd3 dxc4+ 14.Kxc4 Qxc1 15.Kc3 Bd1 16.Ne2 Qxc2+ 17.Kb4 a6 18.Rf1+ Kg7 19.Na3 Nc6 checkmate

A little further along in the game's notes, I recommended that

White probably should have settled for 7.Qxf6+ Nxf6 8.Kxf2 Nxe4+ and a roughly equal game.
However, a quick look at The Database showed that in 23 games my suggestion scored 72% for Black!?

A consultation with Houdini 3 and Stockfish 6 gave me a clue as to what was going on. While both computer programs agreed that the responses 9.Ke1 and 9.Kf1 led to a balanced game, the move 9.Ke2 (3 games) led to an edge for Black, and the move 9.Ke3 (15 games) led to  an advantage for Black. (Both moves are well met by 9...Re8.)


It can be helpful to know what has been played previously, if only to know what moves to avoid!


Finally, it can be noted that after the game continuation, 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ g6 5.Qxe5 Bxf2+ 6.Ke2 Qf6 7.Qd5+ Kg7


The Database contains 7 games with this position: 6 losses for White (one of them ndizvoh - stevebrown, blitz, FICS, 2015) and 1 draw.
