Prized Players

Prizes have been mailed to the top three finishers of the Chessworld Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament: Piratepaul, stampyshortlegs and Sir Osis of the Liver.

I would like to express my thanks to blackburne, who hosted the tournament, and to all of the other players who combined to produce 210 interesting Jerome Gambit games: DREWBEAR 63, GladtoMateYou, Luke Warm, Haroldlee123, eddie43, TWODOGS, Black Puma, gwyn1, metalwarrior1969, Crusader Rabbit and calchess10.

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;

And 8...g6 9.Qf4 Nf6 10.d4 Ke6 11.Qxe5+ Kf7 12.Qxc5 d6 13.Qc4+ d5 14.exd5 Nxd5 15.0-0 Re8 16.Na3 Be6 17.Qd3 Bf5 18.Qf3 Kg7 19.Nc4 c6 20.g4 Be4 21.Qh3 g5 22.Qh5 h6 23.Ne5 Nf6 24.Qf7+ Kh8 25.Ng6+ Bxg6 26.Qxg6 Ng8 27.h4 Re7 28.hxg5 Rg7 29.Qh5 Qd6 30.gxh6 Rh7 31.g5 Qd5 32.Qe2 Ne7 33.Qe5+ Qxe5 34.dxe5 Rg8 35.f4 Nf5 36.b4 Rg6 37.Bb2 Ne3 38.Rf2 Kg8 39.Rd2 Nc4 40.Rd8+ Kf7 41.Rd7+ Kg8 42.Rxh7 Kxh7 43.Bc1 b6 44.f5 Rg8 45.g6+ Kh8 46.Bg5 Re8 47.Bf6+ Kg8 48.h7+ Kf8 49.h8Q checkmate, DREWBEAR 63 - gwyn1, JGTourney4 Chessworld 2009;

Or 8...Nh6 9.Qf4 Rf8 10.Qxe5+ Kxe5 11.d4+ Bxd4 12.cxd4+ Kxe4 13.Nc3+ Kxd4 14.Be3+ Ke5 15.0-0 Nf5 16.Rfe1 Kf6 17.Nd5+ Kf7 18.Rad1 d6 19.Nf4 Nxe3 20.Rxe3 Qf6 21.Nd5 Qd8 22.Re7+ Kg8 23.Rxc7 Qh4 24.g3 Qe4 25.Ne7+ Kh8 26.Rxd6 Bh3 White resigned, mediax - eddie43, Chessworld 2008

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

Playing the Jerome Gambit...

Playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) with White, Gemeinde members wish for the kind of exciting, attacking game that follows...



blackburne - gwyn1
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

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

7.f4 Nf6 The kind of move that is appealing at first glance, as it promotes Black's development, ignores White's threat and plans to return material to slow down the attack. When followed up properly, it leaves White with only a small edge.

Whether this is the best strategy for combatting the Jerome Gambit is another question; but it is important to point out that blackburne has seen this move before.

8.Qxe5+ Kf7 9.Qxc5 d6 10.Qe3

In the past blackburne played 10.Qg5 Re8 11.d3 Kg8 12.0-0 Ng4 13.f5 Qxg5 14.Bxg5 h6 15.Bd2 h5 16.Nc3 b6 17.Nd5 c6 18.Nc7 Ba6 19.Nxa6 Kf7 20.Nc7 h4 21.Nxa8 Rxa8 22.Rf4 Nf6 23.Rxh4 c5 24.Rf1 Rc8 25.Rf3 c4 26.Bc3 Ne8 27.Rg3 a5 28.Rh7 Kg8 29.Rh4 a4 30.Rhg4 Rc7 31.h4 Ra7 32.Bd4 a3 33.b3 cxb3 34.cxb3 Rc7 35.f6 g6 36.Rxg6+ Kf7 37.Rg7+ Ke6 38.Rxc7 Nxc7 39.Rg7 Ne8 40.Re7 checkmate, blackburne - plummy, Chessworld, 2007

Now, against gwyn1, Black has the thematic 10...Nxe4, as the Knight is safe from capture: 11.Qxe4 Re8.

10...Ng4 11.Qg3 Re8 12.Nc3 c6 13.d4 h5

Several times ...h7-h5 has appeared in games in this tournament, sometimes when the Black Rook was still on h8.

14.0-0 b5 15.f5 b4 Undermining White's center before the pawns begin to roll.

16.Ne2 Bxf5

This looks like an oversight, as if Black were expecting 17.exf5 Rxe2. Now his game goes up in flames.

17.Rxf5+ Kg6 18.Nf4+ Kh7 19.Rxh5+ Kg8 20.Qxg4 Rxe4

It is probably time to begin to look for forced checkmates, although different players will prefer different ideas.

21.Qg6 Qf6 22.Qh7+

Of course, 22.Qxe4 was also okay, and led to a mate in ten.

22...Kf7 23.Rf5 Ke7 24.Rxf6 Kxf6 25.Qxe4 Kf7 26.Qg6+ Kg8 27.Ne6 Re8 28.Qxg7 checkmate

The Modern Jerome Gambit

I have been using the games of the current Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament at Chessworld to gain a better understanding of the "modern" (non-5.Nxe5) variations, especially since they make up about 80% of the games there.

Here is a sampling of recent trials.

Yes, Sir!

Here are three more games from the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament at Chessworld – this time, three wins by a Jerome Gambit veteran, Sir Osis of the Liver.

Wing, Center, Wing

While the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has its refutations, if White isn't put out of his misery quickly, he can develop a very interesting game, even if "objectively" he is "worse". Play can develop all over the board, and in the resulting mayhem, anything might happpen...

gwyn1 - Sir Osis of the Liver
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.c3
One of the "modern" variations of the Jerome Gambit – including 5.0-0, 5.Nc3 and 5.d3 – where White avoids the "classical" 5.Nxe5. About 80% of the games in this tournament favored "modern" variations.

5...d5

Black decides to strike back in the center.

6.b4 Bb6

White's plan is clear: knock out the support of the pawn on e5. Black's alternate response was 6...dxe4, responding to an attack on the wing with an attack in the center.

7.b5 Nce7

Again, ...exe4 was possible.

8.Nxe5+ Ke8 9.Ba3


A Queenside Jerome Gambit attack is interesting and unusual. An indication of the fun the opening provides is that there was also a Kingside feint with 9.Qh5+ g6 10.Qf3 Be6 11.d3.
9...Nf6 10.0-0 Nxe4 11.Qf3 Nf5

Black probably needed one more piece in play to be scary, i.e. 11...Be6. Now White hits the Kingside.

12.Qh5+ g6 13.Nxg6


Here we have a complicated, dangerous, and unclear position. Fritz 8 says things will be equal after 13...Kf7 14.Nxh8+ Kg7, even though White would be up the exchange and two pawns. A few more moves give light to the computer's thinking: 15.Nf7 Qf6 16.d3 Nfg3.

Messy, messy, messy – but fun!
13...Nf6 This move, instead, allows White to attack in the center: 14.Re1+ Be3 15.Rxe3+ Nxe3 16.Qe5+ Kd7 17.Nxh8 Nc4.

14.Ne5+

An oversight.

14...Nxh5 15.Re1 Bxf2+ 16.Kxf2 Qh4+ 17.Kg1 Qxe1 White resigned
