The Jerome Gambit: Nice Kitty...

Thursday, August 26, 2010

Nice Kitty...

The following game is another visit with a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) defense / refutation that has sharp teeth and claws – at least in theory. When entering this jungle, I always feel a mixture of excitement and dread as I wonder what will happen this time? See "Closer... But not there yet" and "Jerome Gambit Tournament: Chapter XVI".

perrypawnpusher - JTIV
blitz, FICS, 2010

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

4...Kxf7

My opponent played the Jerome Gambit successfully 3 days before our game: 5.d4 exd4 6.e5 h6 7.c3 dxc3 8.Qb3+ Ke8 9.Nxc3 d6 10.exd6 Qxd6 11.0-0 b6 12.Re1+ Kd8 13.Qf7 Qf6 14.Re8, checkmate, JTIV - NyteFork, FICS, 2010.

5.Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.f4 Qh4+

Whenever I see this move, I suspect that someone has been reading this blog... (Not that that's a bad thing.)

9.g3 Nf3+

And this move almost confirms it...

Interestingly enough, the updated New Year's Database has 25 games (other than the current one) with this position, with White scoring 58%. My own experience with the line is scoring 78% in 9 games.

10.Kf1

This is my current choice, although it is not clear why. The updated New Year's Database has 4 games (other than the current one) with this move, with White scoring 50%. I've scored 33% in 3 games (until now).

The Database has 15 games with the alternative, 10.Kd1, with White scoring 73%. That's in part to me scoring 100% in 6 of those games; but 3 of those wins are identical 11-movers with the "Buyer's Regret Variation".

10.Kf1 Nxh2+

This is an okay followup, although the "magic move" is 10...Ne7. Black has had success with two other moves, as well:

10...Qf6 11.Qd5+ Ke7 12.Qxc5+ Kd8 13.Kg2 d6 14.Qd5 Ne7 15.Qd3 Nd4 16.e5 dxe5 17.c3 Bf5 18.fxe5 Qc6+ White resigned, perrypawnpusher-james042665/Chess.com 2008 ;

10...Qh6 11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6 14.c3 g5 15.Kf2 g4 16.h3 d5 17.hxg4 dxe4 18.d3 d5 19.g5 h6 20.dxe4 dxe4 21.Nd2 Nxd2 22.Bxd2 Bg4 23.Be3 Ke6 24.Rh4 Kf5 25.Bd4 Rh7 26.Rah1 h5 27.Ke3 Ne7 28.R4h2 Nd5+ 29.Kd2 b6 30.Re1 Re8 31.Be3 Rd8 32.Kc2 Rc7 33.a3 Rcd7 34.Bd4 b5 35.Be5 Rc8 36.Kb1 a5 37.g6 b4 38.axb4 axb4 39.g7 b3 40.Bd4 Kg6 41.Kc1 Kf5 42.Rhh1 Nb4 43.Kd2 Rxd4+ White resigned, perrypawnpusher - Temmo, JG3 thematic, ChessWorld, 2008.

11.Kg2 Qh6

Best is the tricky 11...Qg4 and Black holds onto his advantage.

Worst is 11...Qe7 12.Qd5 checkmate, perrypawnpusher - intssed, blitz, FICS, 2010.

12.Rxh2

This move allows Black the chance to slip out of his difficulties. The straight-forward 12.Qd5+ Ke7 13.Qxc5+ Qd6 14.Qxd6+ Kxd6 15.Rxh2 gives White the edge.

12...g6

Necessary was 12...Qe6. The text move turns the game over to White.

13.Qe5+

White's Queen escapes attack with check. Even stronger was 13.Rxh6, since the Black g-pawn would then be pinned.

13...Kc6 14.Rxh6 Nxh6 15.Qxh8
