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?

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

Beware: The Sneak!

Black's biggest dangers in playing against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) are overconfidence, a dismissive attitude and inattention. If any of these plague the second player in the early moves of the game, an otherwise blatant maneuver called The Sneak might arise.

In its starkest form, The Sneak looks like this:


I know what you're thinking: nobody would fall for that, letting the Bishop get trapped.

It is true, not everybody does fall for it. Here are some warnings, though:

An Ultra Modern Jerome Gambit

I have referred to variations of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that don't include (after 4...Kxf7) the move 5.Nxe5+ as "modern" variations, as examples are recent, not from the time or play of Alonzo Wheeler Jerome.

The following game provides an example of what must be considered an ultra Modern variation.

metalwarrior1969 - DREWBEAR
JGTourney4 ChessWorld, 2009


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.a3
One basic tenet of the Modern Jerome Gambit lines is that White has sacrificed enough material with 5.Bxf7, and he shouldn't show any more generosity. He should non-committally construct a safe and solid position, and hope that his ability to out-play Black and take advantage of Black's displaced King will eventually be enough compensation.

5...Nf6 6.h3 TN

Don't smirk: psychology is as much a part of Jerome Gambit play as anything.

6...Nxe4 7.0-0 Nd4 8.Nxe5+ Kg8 9.c3 Nf5 10.d4 Bd6
Now White has the simple 11.Qb3+ Kf8 12.Qf7 checkmate.
Unfortunately, he overlooked this line and lost in 26 moves.
It has been said that an opening novelty will lose the first and last time it is played – but that in the interim it may well capture a whole lot of points. Will we see the Ultra Modern Jerome Gambit again? Only time will tell.

Tactics, Tactics, Tactics



It is not likely that Richard Teichmann, who opined that chess was "99% tactics" ever played the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), but what he said was especially true about such a dodgy opening: by and large the Jerome Gambit Gemeinde lives by the tactic, and dies by the tactic...

Here are three examples from the current Chessworld Jerome Gambit Thematic tournament.

Luke Warm - DREWBEAR 63
JGTourney4 ChessWorld, 2009


Both players have attacks against their enemy King - enough so to keep the game even. Straying from this theme becomes instantly deadly.
22.Rh4 Qxf3 23.Qd2 Ref7 24.a3 Qxd5 25.Qh2 Rf1+ White resigned


Black Puma - Sir Osis of the Liver
JGTourney4 ChessWorld, 2009
This game has been a hammer and tongs affair so far, but seems to have resulted in a balanced, Bishops-of-Opposite-Colors endgame, with a draw in sight. It will take some care, as each side still has a Rook, but the point should soon be split.

34.Be5 g6 35.Rh2+ Black resigned, as he will lose a Rook after 35...Kg8 36.Rh8+






stampyshortlegs - calchess10
JGTourney4 ChessWorld, 2009

Here is a messy, if balanced, game. Maybe White should consider 26.Qe2, and after 26...Nxe4 he can get a draw with 27.Qa6+ Kd7 28.Qb5+ etc?


26.Qe2 Nfd7 27.Qa6+ Kb8 28.Ba7+ Ka8 29.Bb6+ Kb8 30.Qa7+ Kc8 31.Qxc7 checkmate

Exploring

The regular Jerome Gambiteer has an interesting dilemma: play the "book" lines of the gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), all of which lead to established "refutations", hoping that his opponents will fall apart along the way; or go exploring in the side-lines of the opening – which, supposedly if they were any good, would be the main lines, after all, wouldn't they...?


DREWBEAR 63 - Haroldlee123
JGTourney4 ChessWorld, 2009

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


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


7.Qf5+ Kd6 8.c3



A relatively new idea, first played in 2006 as far as I can tell. White looks to support a d2-d4 thrust.


8...Bb6

DREWBEAR 63 has experience on both sides of these lines, especially in the current tournament: 8...Qf6 9.d4 ( 9.Qxf6+ Nxf6 10.d4 Nxe4 11.dxc5+ Nxc5 12.0-0 Ned3 13.Nd2 Ne5 14.f4 Ned3 15.Nc4+ Kc6 16.Ne5+ Nxe5 17.fxe5 Nd3 18.Rf7 Nxe5 19.Rxg7 Nd3 20.b4 Nxc1 21.Rxc1 d6 22.a4 b5 23.axb5+ Kxb5 24.Rxc7 Ba6 25.Rd7 Kc6 26.Rf7 Kb6 27.Rb1 Raf8 28.Rxf8 Rxf8 29.Rc1 Bc4 30.h3 Rg8 31.Kh2 Bd5 32.Rc2 Be4 33.Re2 d5 34.c4 Rxg2+ 35.Rxg2 Bxg2 36.Kxg2 dxc4 37.Kf2 Kb5 White resigned, mediax - drewbear, JG4 thematic Chessworld, 2008) 9...Nd3+ 10.Kd2 Qxf5 11.exf5 Nxc1 ( 11...Nxf2 12.dxc5+ Kxc5 13.Re1 Ng4 14.h3 N4f6 15.b4+ Kc6 16.c4 b6 17.Na3 Nh6 18.g4 Nf7 19.Re7 Rf8 20.Bb2 Ne8 21.Rae1 Nfd6 22.Bxg7 Rg8 23.f6 Bb7 24.b5+ Kc5 25.R7e5+ Kb4 26.Nc2+ Ka5 27.Kc3 Nxg7 28.fxg7 Bg2 29.Rb1 c6 30.Rb3 Ka4 31.Ra3 checkmate, DREWBEAR 63 - GladtoMateYou, JGTourney4 Chessworld 2009) 12.dxc5+ Kxc5 13.Rxc1 d6 14.b4+ Kc6 15.Na3 Bxf5 16.b5+ Kc5 17.f3 Nf6 18.g4 Bd7 19.c4 a6 20.Rab1 axb5 21.cxb5+ Kd5 22.Rxc7 Bc8 23.Rxg7 Nd7 24.Re1 Rxa3 25.Ree7 Rxa2+ 26.Kc1 Rd8 27.Rg5+ Kc4 28.Kb1 Rxh2 29.Re4+ Kb3 30.Kc1 Nc5 31.Re3+ Kb4 32.b6 Rh8 33.Rf5 Bxf5 White resigned, DREWBEAR 63 - metalwarrior1969,JGTourney4 Chessworld 2009;

9.d4 Nd3+

An interesting and novel way to return one of the extra pieces.

10.Kd2 Qf6

10...Nxc1 would preserve the material status quo and would be a good choice – if it didn't lead to a mate-in-two.


11.Qd5+ Ke7 12.Kxd3 h6 13.f4
You have to wonder, if Wilhelm Steinitz ("the Austrian Morphy") ever played the Jerome Gambit (giving "Jerome Gambit odds," of course, to a much weaker player) if he might one day have reached this kind of position. The King is a strong piece!

13...Qd6

The position has gotten strange enough that Haroldlee123 would prefer an exchange of Queens. DREWBEAR 63, on the other hand, would prefer not.

14.Qh5 g6 15.Qh4+ Qf6 16.Qf2 c5

Hitting the center at its apparently weakest point, although 16...d5 was probably better. Now White can get an interesting and relatively equal game with 17.dxc5, but he wants to hold onto his pawn center. It turns out that this goal is unreachable, however.

17.e5 Qf5+ 18.Ke2 cxd4 19.cxd4 Qe4+ 20.Kf1

Or 20.Be3 Bxd4 21.Nc3 Qc2+ 22.Kf3 Qxf2+ 23.Kxf2 Bxc3 24.bxc3 h5 when White has one pawn for his piece, and Black's positional cramp and delay in development are not adequate compensation.

20...Qd3+ 21.Kg1

White played this move – and then resigned. He can lose his Queen to 21...Bxd4, or his King to 21...Qd1+ 22.Qf1 Bxg4+ 23.Be3 Bxe3 checkmate

How do you catch a pirate?


With 15 points out of 18 games, Piratepaul has become a player to be reckoned with (see "Aarrgghhh!") in the ongoing Chessworld Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)Thematic Tournament. So - how do you catch a pirate?

Well, you can always cross your fingers and hopes he makes an oversight, like in his game (move 25) against eddie43. It's not very likely, but it could happen.

Piratepaul - eddie43
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.c3 d6 6.d3 h6 7.a4 a6 8.0-0 Nf6 9.b4 Ba7 10.Kh1 Bg4 11.Nbd2 d5 12.Qb3 Be6 13.Qc2 Ng4 14.d4 exd4 15.cxd4 Nxd4 16.Nxd4 Bxd4 17.Nf3 dxe4 18.Nxd4 Qxd4 19.Qxc7+ Kg6 20.Be3 Nxf2+ 21.Bxf2 e3 22.Qg3+ Kh7 23.Bxe3 Qxb4 24.Rab1 Qe4 25.Rxb7 Qxb7 26.a5 Rhf8 27.Re1 Qb5 28.Bb6 Rf1+ 29.Rxf1 Qxf1+ 30.Bg1 Bc4 31.Qc3 Kg8 32.h3 Re8 33.Kh2 Qf4+ 34.Kh1 Bb5 35.Qb3+ Bc4 36.Qc3 Bd5 37.Qc2 Qg3 38.Qd2 Qxh3+ 39.Bh2 Re1+ 40.Qxe1 Qxg2
checkmate

You could also take the "extra" piece you have as Black, and whip up an attack on his King, like blackburne did.

Piratepaul - blackburne
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.c3 h6 6.d3 Nf6 7.0-0 d6 8.a4 a6 9.b4 Ba7 10.Qb3+ Be6 11.c4 Nd4 12.Qd1 Rf8 13.Nc3 Kg8 14.Kh1 Bg4 15.Be3 Bxf3 16.gxf3 Nh5 17.Rg1 Nxf3 18.Rg2 Qh4 19.Ne2 Rf7 20.Bxa7 Rxa7 21.b5 Ra8 22.a5 Raf8 23.Qb3 Nd2 24.Qc2 Rxf2 25.Qxd2 Rxg2 26.Rg1 Rxh2
checkmate


Or you could simply hang in there, fight every step of the way, and look for a good Frank Marshall-style swindle to get you out of trouble.

In this position from Sir Osis of the Liver - Piratepaul, JGTourney4 ChessWorld, 2009, White is a piece and a couple of pawns down, and if the position weren't complicated, he could resign the game in good faith.

Instead, White gave it one more try.

30.Qxe5 Nf4 31.Rxf6 Nxd3


Threatening the annoying Queen, but reaching a bit too far. Simply good enough was 31...gxf6 32.Qxf6+ Kh7 33.Qxf4

32.Rxh6 checkmate
