Where are all these Jeromes coming from??

Not that I'm complaining or anything, but it seems that I'm facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) more these days, which puts me in a bit of an awkward spot...

FICS rated blitz game 10 5, 2008

1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.c3 Nf6 5.Bxf7+ Kxf7
Transposing into a "modern" (not including Nxe5 for White) version of the Jerome Gambit - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.c3 Nf6. I have about three dozen examples of the c2-c3 line in my database, including my game against Kevin the Fruitbat (see "Jerome Gambit Tournament: Chaper XII").
6.Ng5+

The problem with this variation is that while White can be annoying, he needs a whole lot of cooperation before he can become dangerous – which can be said, I guess, about the Jerome Gambit in general.

6...Kf8 7.Qb3 Qe7

In defending against the mate threat I overlooked the tactical shot 7...Bxf2+ 8.Kxf2 Ng4+ 9.Ke2 Qxg5 netting a pawn.

8.0-0 h6 9.Nf3 Qf7

Safe enough was 9...Nxe4, but I figured that I had enough material to win – I wanted to get to a simpler position where I could begin to make use of it. A Queen exchange would have been a good start.

10.Qd1 d6 11.b4 Bb6 12.a4 a6 13.Nh4 Nxe4


14.d4 exd4 15.Qd3 d5 16.Be3


16...dxe3

Falling into White's "trap" and winning two pieces for the Rook. More precise was 16...Ne5

17.fxe3 Nf6 18.Ng6+ Kg8 19.Nxh8 Kxh8

Black now has three pieces for the Rook, and his King is out of the way. For the next dozen or so moves, we mostly shift pieces.


20.Kh1 Qe7 21.Nd2 Qxe3 22.Qc2 Bd7 23.Rae1 Qg5 24.Nf3 Qf5 25.Qe2 Re8 26.Qd2 Rxe1 27.Qxe1 Qe4 28.Qg3 a5 29.Nh4 Qg4 30.Ng6+ Kg8 31.Qd3 axb4 32.cxb4 Qe4 33.Qg3 d4

Finally I had an idea how to win: promote a pawn.


34.Re1 Qd5 35.Nf4 Qd6 36.b5 Ne7 37.Qh4 Ned5 38.Ng6 Bf5 39.Ne5 d3 40.Rd1

Drops a piece.

40...Qxe5 41.Qc4 Qe2 White resigns

Jerome Gambit: Drilling Down (14)

Here we have another interesting computer - human tussle, with RevvedUp offering and Fritz 8 taking the Queen's Knight Pawn, like Crafty 19.19 did (see "Jerome Gambit: Drilling Down 12"). This time Black did not whip up a devestating counter-attack, but he played mostly even until a blitz-error did him in.


Fritz 8 - RevvedUp
blitz 2 12, 2006

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6
RevvedUp is unimpressed with Fritz 8's novelty 8...Nf4 (see "Jerome Gambit: Drilling Down (13)") and plays a more main-line move. Fritz 8 is objectively worse in this position, but goes about the usual Jerome Gambit tasks.
9.Qe3 Nf6 10.f4 Kf7 11.0-0 Rf8

This is where RevvedUp likes to put his Rook. Putting it on the e-file is an alternative, but perhaps that is where the other Rook is planned to go.

12.Qb3+ Be6 13.Qxb7

He who takes the Queen's Knight pawn sleeps in the gutter...? It is not clear that this pawn grab should be recommended to Jerome Gambiteers.

13...Ne7

Avoiding the pawn fork, but perhaps 13...Qc8, with the offer to exchange Queens, might have been better. Of course, in a human vs human game, White would probably be okay with going into a Queenless middlegame with three pawns for the piece.


14.f5 Bd7 15.Qb3+ Ke8 16.Nc3 c6

17.Kh1 Qb6 18.Qa3 c5 19.d3 Bc6 20.Bf4 Kd7

The game is still fairly well balanced.

21.b3 Ng4 22.Qc1 Ne5 23.Bxe5 dxe5 24.Qg5

White switches the action to the Kingside. Black does not follow quickly enough.


24...Rg8 25.a3 a5 26.Qg3 Qc7 27.Qh3 Rh8



An oversight.


28.f6+ Kd6 29.fxg7 Rhg8 30.Rf6 checkmate

Jerome Gambit: Drilling Down (13)

Up until I reviewed this game, I usually recommended that White use the 7.Qd5+ "nudge" of the Black King before capturing the enemy Bishop on c5 (see "Jerome Gambit Tournament: Chapter XIV") -- but I never had a clear reason why, except to force the monarch back, ultimately interfering with the development of the Black Rook at h8. Perhaps it avoids novelties such as the one Fritz8 found here.

RevvedUp - Fritz 8

7.Qxc5 Nf4 TN

8.0-0 d6 9.Qe3 Qg5 10.g3 Nh3+ 11.Kg2 Qxe3 12.dxe3

Recapture with the other pawn is a bit better.

White's next move is a slip.

12...Ng5 13.f3 Bh3+ White resigns

Jerome Gambit, Paulsen Variation

A few years ago, ever in search for material on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I was wandering the internet, and came upon "Chess Openings -- Version 3.0" [now 3.1] at http://www.csm.astate.edu/~wpaulsen/chess/chess.htm?002137. The site, designed by Dr. William Paulsen, allows visitors to play moves on an opening board and learn the names of variations, positions, etc.

 

So, of course in the "Beginning Position" I entered 1.e2-e4 and received the introduction

King's Opening
This is the most popular first move in chess. Generally, these games tend to be more open and tactical than the Queen's pawn games. This is a highly recomended opening for beginners. Years ago, this was considered the only "proper" move, with e7-e5 the only "proper" responce. However, there have since been many other alternatives discovered. Depending on black's responce, The King's pawn opening can turn into many things:

So I followed along with 1...e7-e5,

Double King's Pawn
The most popular response to the King's opening. This maintains symmetry and disputes control of the center. In theory, as long as Black can maintain symmetry, Black has secured equality. This line leads to many valid openings.

and then 2.Ng1-f3,

"Epine Dorsale - Part 1"
"Epine Dorsale" means the Dorsal Spine. Hence, this is the main spine in which all other openings branch out from. White immediately attacks the black pawn at e5. Black must either defend this pawn, or else attack White's pawn. The most popular way of doing this is with Nb8-c6, which developes a piece at the same time. However, there are some other good alternatives.

and then 2...Nb8-c6 ("Epine Dorsale - Part 2"),

"Epine Dorsale - Part 2"
Black has made the most common move at this point. Now White has the following options:

Very interesting.

So I played 3.Bf1-c4 ("Italian Game") and 3...Bf8-c5

Giuoco Piano
Giuoco Piano means "Quiet Game", although the game is anything but quiet. Perhaps this was quiet compared to the King's Gambit Variations that were popular at the time, but even so the Giuoco Piano often this turns into a real fighting match. However, if White is the weaker player, he can use this formation to his advantage by playing the Giuoco Pianissimo.

Finally I played 4.Bc4xf7+?

Giuoco Piano - Jerome Gambit
White sacrifices his bishop to get the Black king out into the open. Black must take the bishop or be down a pawn.

Of course I hit the "Continue" button to proceed, the board showed 4...Ke8xf7, and there was further information,

White is a piece down, but hopes to regain that piece. In order to do so, it must sacrifice another piece with Nf3xe5.

Making the move, 5.Ne5+

It looks as though Black can be two pieces up by taking the knight. This is what White hopes Black will think.

Indeed, if Black plays 5...Nxe5

Giuoco Piano - Jerome Gambit "Variation I"
Black takes the second piece, but White can regain the material with Qd1-h5+!

After the followup 6.Qh5+

If the king moves toward the knight to protect it, White can check at f5. Black cannot save his knight. White has two pawns for a piece, and the attack isn't over yet.

What I found interesting was the alternative given to capturing the Knight, 5...Ke7

Giuoco Piano - Jerome Gambit "Variation II"
By moving the king instead of taking the knight, White cannot attack the king with his queen. Black ends up with more material.

Well, this is more attention (and respect) than the Jerome Gambit usually gets, so I had to write to Dr. Paulsen and ask about that rare 5th move for Black. His reply

Yes, 5...Ke7 is my own idea. Since Black is already up a piece, by not taking the knight, Black can foil the gambit. In making this network, I try to keep my eyes open to possibilities "outside of the box." Version 3.0 [of "Chess Openings"] came out in 2003, but there were only about 750 moves back then. Because the new version allows moves to be added so easily, there are now over 5000 moves.

In light of this it certainly seems reasonable (at least until historical precedents are uncovered) to give 5...Ke7 the title of "Paulsen variation" and award the good doctor (PhD) membership in the Jerome Gambit Gemeinde (see "The Jerome Gambit Gemeinde (early)" and "The Jerome Gambit Gemeinde (modern)") – even though there is one earlier example of the line in my database (presented in an earlier post, as well: see "An Odd Line in an Odd Line").

By the way, "guest 1200" is our old pal and Gemeinde member, Louis Morin.

6.Qh5

This is the strongest response.

It is a odd thing to recall, but the position is now the same as it was with several games that I played against the computer program WeakDelphi (see "I can't seem to get the hang of these things...") – only with White now to move.

6...Qf8

Black's best plan here seems to be to return a piece with 6...Bxf2+ 7.Kxf2, followed by covering the f7 square with 7...Qf8+; when White is simply a pawn ahead.

Of course, there's always saving the Bishop with 6...d6 7.Qf7 checkmate, stivb_99 - spymaster, gameknot.com, 2008; but that seems a bit too drastic.

7.0-0

Consistent, instead, was 7.Nxc6+ followed by 8.Qxc5+ and White is two pawns up, whether or not he swaps Queens.

7...d6 8.Ng6+ hxg6 9.Qxh8 Nd4

An interesting position. Black's advantage in development means that his two-pieces-for-a-Rook-and-two-pawns imblance gives him an edge.

10.Na3 Ne2+

I think better was more development: 10...Be6 11.d3 Nf6 12.Qxf8+ Rxf8.

11.Kh1 Be6 12.d4 Bxd4 13.f4

Going after the enemy King, regardless. After all, this is a blitz game, and this is the Jerome Gambit.

13...Qf6 14.Nb5

At this point White needs a very good distraction. Luckily, it works.

14...Bb6 15.Bd2 a6 16.Nc3 Nxc3 17.Bxc3 Bd4
br /> This last move looks ok at first glance, but actually it is a tactical oversight.

18.e5 dxe5 19.fxe5 Qxe5 20.Bxd4

The move to make was 20.Qh4+ followed by the Queen capturing on d4 nabbing a piece. White shows, however, that his line of play also wins for him.

20...Qxd4 21.c3 Qe5 22.Rae1 Qd5 23.Qxg7+ Kd6 24.Rd1 Qxd1 25.Rxd1+ Kc6 26.Qxg6 Black resigns.

Jerome Gambit: Drilling Down (12)

Searching for improvements in play against the ...Ng6 defense to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), the computer grabs a pawn – and has to struggle mightily not to fall to a crushing counter-attack.
Crafty 19.19 - RevvedUp
blitz 2 12, 2006
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+Ng6


7.Qxc5 Nf6 8.0-0


Crafty 19.19 prefers safeguarding the King over protecting the King's pawn, as 8...Nxe4 could be met with 9.Qd5+
8...d6 9.Qe3 Rf8


Likewise, RevvedUp castles his King by hand.

The alternative Rook placement on the e-file has been seen: 9...Re8 10.d3 ( 10.Nc3 d5 11.d3 d4 12.Qf3 dxc3 13.bxc3 Ne5 14.Qg3 g6 15.Bg5 Kg7 16.Qh4 Rf8 17.f4 Nf7 18.e5 Nxg5 19.exf6+ Kg8 20.fxg5 Bf5 21.Rfe1 Rf7 22.Re5 Qd6 23.Qd4 Qa6 24.Rae1 Qxa2 25.c4 Qxc2 26.Re8+ Rf8 27.f7+ Kxf7 28.R1e7+ Kg8 29.Qg7 checkmate, blackburne - Sir Osis of the Liver, www.chessworld.net 2008) 10...Ng4 ( 10...d5 11.f3 Bd7 12.Qf2 Kg8 13.Bg5 Bb5 14.Bxf6 Qxf6 15.Nc3 Bc6 16.exd5 Bxd5 17.Nxd5 Qxb2 18.Nxc7 Rec8 19.Nxa8 Rxc2 20.Qg3 Qd4+ 21.Kh1 Qxd3 22.Qb8+ Nf8 23.Qxb7 Qg6 24.Qb3+ Kh8 25.Rg1 Qc6 26.Rab1 Rc3 27.Qf7 Qxa8 28.Rb7 Ra3 29.Qxg7 checkmate, perrypawnpusher -MoonCat, FICS, 2007) 11.Qe2 Qh4 12.h3 N4e5 13.f4 Nd7 14.Nc3 c6 15.f5 Nge5 6.d4 Nf6 17.dxe5 Black resigned, Schlenker - Sfrd, from Randspringer

The thematic 9...d5 was also possible.

Now Crafty 19.19 goes pawn-hunting, allowing RevvedUp to unleash a powrful attack.

10.Qb3+ Be6 11.Qxb7 Kg8 12.Nc3 Ng4 13.h3 Nxf2 14.Rxf2 Rxf2 15.Kxf2 Qh4+ 16.Kg1 Rf8 17.Nd1

As I've mentioned (see "Jerome Gambit: Don't open that door!") sometimes when I play over a Jerome Gambit game, I secretly root for Black... Here RevvedUp is pounding his adversary (who is rated over 1,000 points higher than he is).
17...Bxh3

It was not obvious at blitz speed that Black had a mate-in-9 here: 17...Nf4 18.Qa6 Qg3 19.Ne3 Nxh3+ 20.Kh1 Qe1+ 21.Nf1 Rxf1+ 22.Qxf1 Qxf1+ 23.Kh2 Nf4 24.Kg3 g5 25.d4 Qxg2 checkmate. He still has the better game after the text, though.
18.Qb3+ Be6

A humorous echo of move 10! However, after the safer 18...Kh8 the computer cannot escape mate.

19.Qxe6+ Kh8 20.d3 Qe1+
21.Kh2 Qxd1

Good enough for the win, but 21...Rf1 instead was crushing.

22.Qd5 h6 23.Qe6 Rf1


Tough guy! Why not sac a piece?

24.Qxg6 Rh1+ 25.Kg3 Qe1+ 26.Kg4




26...Rh4+
Arrrgh! How unfortunate: 26...Qf2, hemming in the enemy King and threatening the pawn at g2 was the move that still won.
But this is blitz, and such things happen.
Crafty 19.19's King can escape – into enemy teritory – and RevvedUp is done for.

27.Kf5 Qf1+ 28.Ke6 Qf8 29.Kd7 Rh1 30.Kxc7 Qe7+ 31.Kc6 Rf1 32.Bg5 Qf8 33.Rxf1 Qxf1 34.Be3 Black resigns

Jerome Gambit: Drilling Down (11)

In this second round of games, chess detective RevvedUp and his computer companions exlore a defense to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that simply returns one of the two pieces that White has sacrificed.


Play initially revolves around the e4-pawn and the e-file, but long term strategies will involve the familiar pawns-vs-piece struggle.

Ouch!

Hoist by my own petard...

I had just completed the previous post (see "Back at me") when I decided to log onto the Free Internet Chess Server (FICS) for a quick game or two.

I use slower blitz time controls when I play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) but sometimes when I'm due to have the Black pieces, I'm willing to move a bit faster.

(By the way, this post's title means "to be undone by one's own devices" according to the American Heritage Dictionary.)

Castled - perrypawnpusher
blitz game 3 0, FICS, 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4

The Evans Gambit. I don't think I've ever faced that before.

4...Bb6 5.b5 Na5

The last two moves are certainly not the best way to defend.

6.Bxf7+

The Evans Jerome Gambit! Wow! Why not? My opponent is rated 200 points above me, perfect for offering "Evans Jerome Gambit odds"!

Wait a minute – I'm defending... So much for a relaxing game with the Black pieces.

6...Kxf7 7.Nxe5+ Kf8 8.Qf3+

Stronger, but still better for Black, is 8.Nc3 Nf6 9.0-0.

8...Qf6 9.Qxf6+

I'm not sure that this is what White wants. Perhaps 9.Bb2 Qxf3 10.Nxf3 Nf6 helps him out more.

9...Nxf6 10.d3 d6

With only three minutes for the game, we were both moving quickly – too quickly. It should not have been too hard for me to find the sequence 10...Bd4 11.c3 Bxe5 12.f4 Bd6 13.e5 Be7 14.exf6 Bxf6.

11.Nf3 Bg4 12.Nfd2 Re8 13.0-0 Ke7

Missing the trick (now and later) 13...Be2 14.Re1 Bxd3 15.cxd3 Bd4.

14.h3 Be6

15.Nc3 Kd8 16.a4 Nd7 17.Nf3 Ne5 18.Nxe5 dxe5 19.Bg5+ Kc8

Castling by hand to the Queenside. With a piece for two pawns, Black has the edge; but his pieces on the Queenside are jumbled.

20.Kh1 h6 21.Bd2 g5 22.g4 Rhf8

Starting aggression toward the King with 22...h5 was a more dynamic idea.

23.Ne2 Rxf2

A mistake: my opponent was low on time and I wanted to "pressure" him. Instead, this gives Castled a chance to get an edge.

24.Bxa5

Getting part of the idea right: If he played 24.Rxf2, it would have worked out – Black has to play 24...Nb3 (if 24...Bxf2 then 25.Bxa5) 25.cxb3 Bxf2 26.Rf1 Bc5.

24...Rxf1+ 25.Rxf1 Bxa5 26.Ng3 Kd7 27.Nh5 Ke7 28.Ng7 Kd7

Playing faster and faster... This move loses the exchange, but if I can avoid catastrophic errors then my ally, The Clock, will win the game for me.

29.Nxe8 Kxe8 30.Rf6 Ke7 31.Rxh6 Bf7 32.Rh8 Bb6 33.Rb8 Ba2 34.Rxb7 Bb1 35.Rb8 Bxc2 36.Rg8 Bxd3 37.Rxg5 Bxe4+ 38.Kh2 Be3

Horrid, but see the above note. Tick... tick... tick...

39.Rxe5+ Kf6 40.Rxe4 Bc5 41.Rc4 Bd6+ 42.Kg2 Ke6 White forfeits on time

Ugly, ugly, ugly!

But for once in a quick game, time was on my side, even if the Jerome Gambit was not.
