Cuts Like A Knife

Sharp variations can work in favor of the gambiteer, or cut against him. It is important to be as up-to-date as possible on the tricky variations.

I recently downloaded some more games from the Free Internet Chess Server (FICS), and, as well as checking out some "old" Jerome Gambiteers (e.g. drumme, HauntedKnight, Petasluk), looked at the efforts of a relatively new member of the Gemeinde, ZahariSokolov.

In the following game he faces a rare, but old and dangerous defense, and, under pressure, chooses the wrong line (although, in another game in the notes, this also leads to victory), and suffers defeat.

I have added some game references for Readers to have a better idea of how to deal with this kind of play.   

ZahariSokolov - Quarte
standard, FICS, 2015

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Nf3+ 

This surprising move, attributed to Norton - who defeated Alonzo Wheeler Jerome with it in a correspondence game in the early years of the gambit - rips open White's Kingside and makes him vulnerable to attack.

9.gxf3

Probably the only move, although I have gotten away with 9.Kf1 a couple of times in perrypawnpusher - igormsp, blitz, FICS, 2011 (1-0, 13), and perrypawnpusher - rheapennata, blitz, FICS, 2012 (1-0,12); while Jerome, as mentioned, did not - Jerome,A - Norton,D, Correspondence, 1876 (0-1, 42).

ZahariSokolov, himself, a few days earlier, had gotten away with 
9.Kd1: 9...Nd4 (9...Ne7!) 10.Qd5+ Ke7 11.Qxc5+ d6 12.Qxd4 Bg4+ 13.Ke1 c5 14.Qxg7+ Ke8 15.Qxg4 Nf6 16.Qe6+ Qe7 17.Qxe7+ Kxe7 18.d3 h6 19.Nc3 a6 20.Be3 b5 21.Ke2 Rhg8 22.g3 b4 23.Nd5+ Nxd5 24.exd5 Kf6 25.Rae1 Kf5 26.Kd2 h5 27.Bf2 Rae8 28.Rxe8 Rxe8 29.Re1 Rxe1 30.Bxe1 Kg4 31.Ke3 Kh3 32.f5 Black resigned, ZahariSokolov - LAVAL, standard, FICS, 2015


9...Qh4+ 10.Ke2

The "only" move, this time, is 10.Kd1: CFBBlind - Quandary, FICS, 2001 (1-0, 18); perrypawnpusher - Sir Osis of the Liver, JG3 thematic, ChessWorld.net, 2008 (1-0, 19);  perrypawnpusher - sjeijk, blitz, FICS, 2011 (1-0, 19);  ZahariSokolov - GhengusFungus, FICS, 2014 (1-0, 11).

10...Qf2+ 11.Kd3 Qxf3+ 12.Kc4 b5+ 13.Kxb5 Qe2+

A testimony to White's ability to struggle and survive: 13...a6+ 14.Kc4 Nf6? 15.Qxc5+ Ke6 16.Re1 Qxf4 17.d3 Qd6 18.Qxd6+ Kxd6 19.e5+ Kc6 20.exf6 gxf6 21.b3 d5+ 22.Kc3 Bg4 23.Bf4 h5 24.h4 f5 25.d4 Rhe8 26.Rxe8 Rxe8 27.Be5 Rf8 28.Nd2 f4 29.Rf1 f3 30.Rf2 Kb6 31.Kd3 c5 32.c4 dxc4+ 33.bxc4 cxd4 34.Bxd4+ Kc6 35.Ke4 Re8+ 36.Kf4 Rf8+ 37.Kg3 Rd8 38.Bf6 Rd3 39.Nxf3 Bxf3 40.Rxf3 Rxf3+ 41.Kxf3 Kc5 42.a3 Kxc4 43.Kf4 Kd5 44.Kg5 Ke6 45.Bc3 Kf7 46.Kxh5 Kg8 47.Kg6 Kf8 48.h5 Black resigned, gibonacci - jschulte, GameKnot.com, 2007.

A testimony to an early chess computer's terrible addiction to grabbing material: 13...Rb8+ 14.Ka5 Bb4+ 15.Ka4 Qxh1 16.Qe5+ Kc6 17.Qd5+ Kb6 18.Qb5 checkmate,  Young,J - Chess, Computer game, 1979. 

14.d3 Rb8+ 15.Ka5 Bb4+ 16.Ka4 Qxc2+ 17.b3 Qc6+ White resigned

Complexity In The Notes.

ZahariSokolov has played some very interesting Jerome Gambits at FICS lately. The following games shows off one of the aspects of the Jerome - that even the "winning" lines for Black are tricky for the second player, as are the "losing" lines for White.

So much of the complexity this time is in the notes.

ZahariSokolov - GhengusFungus
standard, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Nf3+

This rogue knight move marks the "Norton Variation", as opposed to one move later - 8...Qh4+ 9.g3 Nf3+!? - which would lead to a very sharp and complicated Queen sacrifice that wins for Black.

Nonetheless, The Database has 9 games with the Norton line, and White wins 8 of them. There are 44 games with the Queen check line, and White wins half of them.

Perhaps GhengusFungus was unfamiliar with the Queen sac, or he found the Knight move to be disturbing enough.

9. gxf3 

I was able to get away with the erroronious 9.Kf1? twice, in blitz games,  perrypawnpusher - igormsp, blitz, FICS, 2011 (1-0, 13) and perrypawnpusher - rheapennata, blitz, FICS, 2012 (1-0, 12); but long ago, at a slower pace, the Gambit's creator was not Jerome,A - Norton,D, Correspondence 1876 (0-1, 42).

9... Qh4+ 10.Kd1

Again, this is the correct square for the King, although two games in The Database show White winning after 10.Ke2? Young,J - "Chess Challenger 10" Computer, 1979 (1-0,18) and gibonacci - jschulte, GameKnot.com ,5d/move, 2007 (1-0, 48). 

10... Qe7 

In "Vortex" I wrote

White's best chance is 11.Qe5+ Kc6 12.b4!? when White can probably eke out a draw, whether or not the pawn is captured, but the play is very difficult.

That is a fair assessment of this Norton variation: a very complicated game, but a draw, with a lot of hard work by White.

Two games show White successful after 10...Ne7!?: CFBBlind -Quandary, FICS, 2001 (1-0, 18) and perrypawnpusher - sjeijk, blitz, FICS, 2011 (1-0,19); while White had a draw against 10...Qf2 - until he was given more in perrypawnpusher - Sir Osis of the Liver, JG3 thematic, ChessWorld.net, 2008 (1-0,19).

How did Black deal with all these complications? Apparently he relaxed too soon. 

11. Qd5 Black checkmate
