"Come into my parlor..."



Every chess game that I play, especially one involving the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) contains something – a move, a position, an idea, a combination, an error – that makes it memorable. At times it's even the lack of something that makes the game stick with me.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6

7.Qxe5 Nf6

This is such a reasonable move, protecting the Rook, and I've seen it before (vs Alternative, MsD and Brain50). The problem is, of course, that after eight moves White is two pawns up, instead of being two pieces down. In light of Geoff Chandler's "Blunder Table", it is clear that at my level of play, this need not be terminal – but it is bad form for play against the Jerome Gambit.

8.Qxc5 Qe7 9.Qxe7+ Kxe7 10.Nc3 d6 11.d4
There's nothing really exciting going on, just the two-pawn edge.

11...Re8 12.Bg5 Kf7 13.Bxf6 Kxf6 14.0-0 Be6



15.f4 d5 16.e5+ Kf5


Now this is interesting.

17.h3 h5

18.Rae1

White does better with 18.Ne2, as in 18...Bc8 19.g4+ hxg4 20.Ng3+ Ke6 21.hxg4.

18...c6 19.Ne2 h4
Black holds back the White g-pawn – he thinks – to further safeguard his King. Instead, the mating net is put in place.

20.g4+ Ke4 21.c3

Readers no doubt have noticed that there was a mate, instead, with 21.Rd1 Bf5 22.Nc3+ Ke3 23.gxf5 gxf5 24.Rd3#

21...Kd3 22.b3


Looking for a way to keep the intruder trapped.

22...b5

Black sends a commando to help his King escape.

23.Rf3+

I take my hat off to any reader who spotted that with 23.Rd1+, instead, the Black King is forced to c2, when 24.Rb1 would set up a mating net due to the threat of Kg1-f2-f3 and then mate with the Rooks. Black would have to sacrifice heavily to avoid that.

23...Kc2
24.Rf2


The key move here is 24.Nc1: 24...Kb2 25.a3 ( 25.a4 Bf5 26.gxf5 gxf5 27.Re2+ Ka1 28.Nd3 Rg8+ 29.Kh2 Rg1 30.Kxg1 Rg8+ 31.Kh2 Rg2+ 32.Kxg2 bxa4 33.Rf1#) 25...Bxg4 26.hxg4 Rxe5 27.fxe5 Rf8 28.Re2+ Kb1 29.Rxf8 h3 30.Nd3 h2+ 31.Rxh2 g5 32.Rf1#

24...Kb2 25.f5
Phooey! Enough time wasted on mates that I can't find. Let's put those extra pawns to work!

25...gxf5 26.gxf5 Bg8 27.Nf4+ Ka3 28.Ng6

Not the best series of moves, but I've got a general outline of what I need to do.

28...b4 29.cxb4 Kxb4 30.Nxh4 c5 31.dxc5 Kxc5

Black has a passed pawn now, too, but it is too late for it to change the outcome of the game.

32.f6 Be6 33.Nf5 Rf8 34.Rc1+ Kb4 35.h4
As much psychology as chess play.

35...Rh8 36.Nd4 Rae8 37.Nxe6 Rxe6 38.f7 Rf8 39.Re1 Rg6+ 40.Kh2 Rh6 41.Kh3

Jerome Gambit Tournament: Chapter XVIII

Here is my last game of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament – and a good thing, too.

I was very lucky in this game, getting away with playing "routine" moves – several of which could have been punished, if my opponent had been a bit less "routine" himself.

Still, as noted in "Overrated!" the win here gave me a final score of 16 - 2, and first place in the tournament by three points.

Rybka suggests 7.c3 dxc3 8.Nxc3 with an advantage to Black.

Black is a piece up, his King will soon be castled-by-hand, and a nice, calm game would suit me fine.

8.Nc4 Re8 9.Qe2 Rxe4

This capture is a blunder and should drop a Rook: the proper move is 9...Nxe4
10.Qd3

Simply 10.Ng5+ followed by 11.Nxe4 puts White back into the game.
10...Kg8 11.Bg5 Re8 12.Rae1 Bd7

White is better developed, but with nothing going on, Black has a chance to catch up -- and he does have that extra piece.

13.Rxe8+ Bxe8 14.Re1 Bf7 15.Bxf6 Qxf6 16.h3 Re8 17.Rxe8+ Bxe8



18.Kh2 Ne5

Again, throwing away a piece. Developing with the simple 18...Bg6 was better.

19.Nfxe5
Unfortunately capturing with the wrong Knight. 19.Ncxe5 Kf8 (19...dxe5 20.Qc4+ Bf7 21.Qxc5) 20.Nc4 left Black with only a small advantage.
19...dxe5 20.a3 e4 21.Qxe4 Bc6 22.Qg4 Qxf2 23.Ne5 Bd6

24.Qc8+ Qf8 25.Qxf8+
Trading Queens is the equivalent of resigning, although after the better 25.Qe6+, protecting the pinned Knight, Black still is losing.
25...Kxf8 White resigns.

Jerome Gambit Tournament: Chapter XVII


At this point in the tournament I had two games left to complete, both against brain50. That made this game my last chance with the White pieces and the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)


perrypawnpusher - brain50
JG3 thematic www.chessworld.net, 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Nf6


A move seen on this blog before in perrypawnpusher - MsD, FICS rated blitz game, 2007 (see "Les Femmes des Echecs...& the Jerome Gambit") and which I'd faced a few years earlier, perrypawnpusher - Alternative, FICS rated blitz game, 2005: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Nf6 8.Qxc5 d6 9.Qe3 Re8 10.d3 Kg7 11.0-0 d5 12.Qh6+ Kg8 13.exd5 Nxd5 14.Nc3 Nxc3 15.bxc3 Qf6 16.Bd2 Qg7 17.Rae1 Rxe1 18.Rxe1 Qxh6 19.Bxh6 Bf5 20.Re7 Rc8 21.Bf4 Kf8 22.Rxc7 Rxc7 23.Bxc7 Ke7 24.Kf1 Kd7 25.Be5 Kc6 26.Bd4 a6 27.c4 b5 28.cxb5+ axb5 29.a3 Be6 30.Ke2 Bd5 31.g3 Ba2 32.c3 Kd5 33.Ke3 Bb1 34.Bg7 Ba2 35.f4 Bb1 36.h3 Bc2 37.g4 Ke6 38.Ke4 Kf7 39.Bd4 h6 40.f5 g5 41.Kf3 Bxd3 42.Kg3 Be2 43.h4 Bd1 44.hxg5 hxg5 45.Be3 Kf6 46.Bb6 Ke5 47.Bd8 Ke4 48.Bxg5 Kd3 49.Bf6 Kc4 50.g5 Kb3 51.g6 Bh5 52.Kf4 Kxa3 53.Kg5 Bd1 54.Kh6 Bb3 55.Kg7 b4 56.cxb4 Kxb4 57.Kf8 Kc5 58.Be7+ Kd5 59.f6 Ke5 60.g7 Kf5 61.g8Q Bxg8 62.Kxg8 Kg6 63.f7 1-0

By playing 7...Nf6, Black gives back the sacrificed piece, leaving White a pawn up in a balanced position. That's more than I usually get with 1.e4 e5 and a whole lot more than what I usually get with the Jerome Gambit.

Black should have played 7...Qe7, Whistler's Defense, as I did against blackburne ("Jerome Gambit Tournament: Chapter VIII") and as my buddy A. B. Hailey faced ("
Beware: Mad Dog!").

8.Qxc5 d6

Black could have tried 8...Nxe4 on this or the next move: the open e-file leading up to White's King makes this possible.

9.Qe3

Vazquez played 9.Qc3 in his match game against Carrington (see "Flaws (Part II)").

9...Be6 10.0-0 Rf8 11.Nc3 Kg7 12.d3



Brain 50 has castled-by-hand, and has an edge in development, while I have a couple of extra pawns. No need for me to do anything exciting, just slowly build my advantage.

12...c5
13.f4 Ng4 14.Qg3 Rc8
After the game Rybka suggested 14...h5 15.h3 h4 16.Qe1 Nh6 17.Bd2 Bd7 18.Qe3 Re8 19.Nd5. The waves are still going to break over the Black King's head.
15.f5 gxf5 16.h3



Better here was 16.exf5, as 16...Bxf5 would have been answered by 17.Rxf5 Rxf5 18.Qg4+. Black now went in for a series of exchanges.

16...f4 17.Bxf4 Rxf4 18.Rxf4 Qg5 19.Rxg4 Bxg4 20.Qxg4 Qxg4 21.hxg4



White's extra piece will prevail.

21...Kg6 22.Rf1 Rh8 23.Rf5 a6 24.Nd5 Black resigned

Jerome Gambit Tournament: Chapter XV

My opponent in this game finished second in the tournament (see "Overrated!") with a score of 13-5, including a vicious score with the Black pieces of 8-1 against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). As you will see in this Chapter and next, we split our two games.

Temmo - perrypawnpusher

JG3 thematic www.chessworld.net, 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4


A line recently popular – brain50 played it in all 9 of his games as White in this tournament (his game against me will be seen in a later Chapter). Temmo did so 6 times, and Sir Osis of the Liver 4 times. In another ChessWorld Jerome Gambit theme tournament, dandoo played it 6 times.

After the following pawn capture, the game has transposed to Wright - Hunn, Arkansas 1874 (see "
Brilliant but not sound").

5...exd4 6.Qd3


Played also by Temmo vs Sir Osis of the Liver (0-1, 32).

I think that White should try 6.c3 here, aiming to build a full pawn center after cxd4. There is also the trap 6...dxc3 7.Qd5+ winning back a piece.

6...d5 TN 7.Ng5+ Kf8 8.Qf3+ Qf6 9.exd5 Qxf3 10.Nxf3 Nb4 11.Na3 Nxd5

There's not a lot of excitement left in the game.

12.Nc4 Bf5 13.Nfe5 Re8 14.0-0
This puts his Knights at risk. Better was the supportive 14.Bf4.

14...b5 15.g4 Bxc2


Sloppy: 15...bxc4 won a piece.


16.Nd7+ Ke7 17.Nxc5 bxc4 18.Re1+ Kf7 19.Rxe8 Kxe8 20.Bg5 Ngf6 21.Re1+ Kf7 22.h3 Re8 23.Rxe8 Kxe8 24.Bxf6 Nxf6 25.Ne6


Forking three unprotected pawns and apparently winning one, but there will be no time for that.


25...d3 26.Kf1 d2 27.Nxg7+ Kf7 28.Nf5 d1Q+ 29.Kg2 Be4+ 30.Kg3 Qf3+ 31.Kh4 Bxf5 32.b3 Bxg4 White resigns

Overrated!


Well, it's offical: all the games of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Tournament that I was participating in at
ChessWorld.net have been completed.

While I will continue to bring you my struggles, one-by-one, in more of the "Jerome Gambit Tournament: Chapter Whatever" posts I thought I would tip my hand by sharing the fact that I scored 16-2-0, meeting my goal of going 9-0-0 against the Jerome Gambit, while racking up a defensible 7-2-0 record with the Gambit.

That result was good enough for first place, although because of my ridiculously over-inflated rating, I lost over 100 rating points with it.

Still, I finished three points ahead of Temmo, at 13-5-0.

Following quickly were Kevin the fruitbat with 12-6-0, Sir Osis of the Liver with 11-6-1, Hogmaster with 10-6-2 and Blackburne with 10-7-1.

Hogmaster had the second-best score with White with the Jerome Gambit: 6-3-0.

Temmo and Sir Osis of the Liver were equally cruel with Black to the Jerome Gambit, scoring 8-1-0 against it.

The field finished with drewbear at 8-10-0, Gary_Seven at 5-13-0, brain50 at 3-15-0 and Capt.Mandrake at 0-18-0.
