Huntin'

I guess it's a good thing that I read this Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) blog – every once-in-a-while there's something here that I can use in my own games...

perrypawnpusher - avgur
blitz 5 5, FICS, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6
10.0-0
Up to here, this is the same as perrypawnpusher - peroneal, blitz, FICS, 2009, which I analyzed a few days ago. My hope was that I had learned something.

10...Be6 11.f4 Bc4
This Bishop maneuver is reminiscent of perrypawnpusher - Kotimatka, blitz, FICS 2009, (also covered less than a week ago) but in that case I had already played d2-d4, so I didn't have the helpful reply I have here.

12.d3 Bb5 13.c4
A bit of over-thinking, here. The idea was to chase the enemy Bishop off of the a6-f1 diagonal, so I could play f4-f5 and answer Black's ...Ne5 with d3-d4. Ooops! That would leave the same c4-pawn vulnerable to capture... Luckily, I figured that out – right after I played the move, of course.

I probably would have had the same success (or more) with 13.Nc3, which also attacks the Bishop.
13...Bc6 14.f5 Ne5 15.Nc3 Qd7 16.b3 Qf7 I'm not sure what Black is doing with his Queen maneuvering, but I'm ready to get the "Jerome pawns" moving.

17.d4 Neg4 18.Qe2
Wouldn't you know it, after the game Rybka 3 preferred 18.Qg3! (Am I ever going to put the Queen on the right square?) Then Black can't win the White e-pawn without leaving his Knight on g4 hanging, while the protective 18...h5 lets White get in 19.e5. Thank you, Rybka.

18...Qe7 19.Bg5 h6 20.Bxf6
Keeping the pin with 20.Bh4 was stronger.

20...Nxf6 21.Rae1


Getting the last piece into place before advancing the pawns. White is close to even.

21...h5

Understandably, Black does not want another pawn joining the party with g2-g4, but moving the King (21...Kf7) might have been safer. Also, if the center opens up, Black's Rooks will wind up there, which means that later the h-pawn could be at risk.

It's not just White who can have a hard time choosing moves!

22.e5 dxe5 23.dxe5 Ng4 24.h3 Nh6
White finally gets the advantage. Black had an interesting save of his Knight, instead of the retreat: 24...Qc5+, since after 25.Kh1 the g4 Knight can't be captured because White would get checkmated.

25.Qf2
White should have grabbed the pawn at h5 instead.

25...Kd7

Black's King and Queen have had a horrible time deciding where to go. This continues to help White.

26.Qd4+
One of the things that I've discovered while going over this game and the several prior ones is that getting the "Jerome pawns" to the 5th (or 5th and 6th) rank is more of a strategic victory than a tactical conclusion – White has more space, and can use it; he can even conjure up threats; but there's still a lot of work to do.

26...Ke8

Taking refuge with 26...Kc8 was relatively safer, but Black is still troubled.

27.f6 Qe6 28.fxg7 Rg8 29.Rf6 As per the note after White's 26th move.
29...Qd7 30.Qxd7+ Kxd7 31.e6+ Kd6 32.e7+ Kc5
Wandering off. The fresh air doesn't help.

33.Rxh6 Rxg7 34.Rxh5+ Kd4
His Majesty has his own plans.

35.Nb5+ Kd3 36.g4 Rag8
Black's counter-attack comes too late.

37.Rhe5 Rh7 38.e8Q Bxe8 39.Rxe8
Time was running down on our clocks. Time to wrap the game up.
39...Rgg7 40.Rd8+ Kc2 41.Re2+ Kc1 42.Na3 Rxh3 43.Rc2 checkmate

Diagnosis: Misplaced Knight


It has been said that if one piece sits poorly in a chess game, the entire position becomes poor for that player.

I think that remark usually refers to games played above the level of those involving the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), but it does appear true that in the following game, my opponent's Queen Knight (and to some extent, his King Knight) caused him a lot of difficulty.

Of course, I was cooperative: as Genrikh Chepukaitis said “You need not play well - just help your opponent to play badly”

perrypawnpusher - Kotimatka
blitz 6 5, FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian.

4.0-0 Bc5 5.Bxf7+ Transposing to a Jerome Gambit, of course. I think the extra 0-0 helps White more than the extra ...h6 helps Black.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6
8.Qd5+

I continue to prefer Alonzo Wheeler Jerome's "nudge" here, instead of the direct capture of the Bishop.

An alternative, from the current Chessworld Jerome Gambit Thematic Tournament, is 8.Qxc5 d6 9.Qc4+ Be6 10.Qe2 Nf4 TN 11.Qf3 g5 12.d3 Nf6 13.Bxf4 Bg4 14.Qe3 gxf4 15.Qxf4 Qd7 16.Nc3 c6 17.f3 Be6 18.Qe3 Rag8 19.Rf2 Rg6 20.f4 Ng4 21.Qf3 Ke8 22.f5 Rf6 23.fxe6 Qxe6 24.Qh3 Rxf2 25.Qh5+ Kd7 26.h3 Rxg2+ 27.Kxg2 Ne3+ 28.Kf2 Nxc2 29.Rc1 Rf8+ 30.Ke2 Nd4+ 31.Kd1 Rf1+ 32.Kd2 Nf3+ 33.Kc2 Rxc1+ 34.Kxc1 Ng5 35.h4 Qh3 36.Qxh6 Qf1+ 37.Kc2 Qf2+ 38.Kb3 Qb6+ 39.Kc2 Qf2+ 40.Kb3 Qb6+ 41.Kc2 Qf2+ 42.Kb3 Draw, Black Puma - TWODOGS, JGTourney4, ChessWorld, 2009

8...Ke8 9.Qxc5 d6
Earlier this year I faced 9...Qe7 10.Qe3 Nf6 11.Nc3 c6 12.f4 b6 13.f5 Ne5 14.d4 Ba6 15.dxe5 Qxe5 16.Re1 Kf7 17.Qf3 Rhe8 18.Bf4 Qc5+ 19.Be3 Qb5 20.Bd4 Qxb2 21.e5 Nd5 22.e6+ Kg8 23.Qg4 Nxc3 24.Qxg7 checkmate, perrypawnpusher - Cibola, FICS, 2009

10.Qe3 Ne5

I am sometimes surprised that my opponents think so little of the Jerome Gambit that they act as if anything can be played against it. White is close to having an equal game after this move.

11.d4 Ng4 12.Qg3 N8f6

This unnecessarily complicates things.

13.Nc3
The position is trickier than I thought when I was playing. For example, after 13.f3, Black's Knights prance around: 13...Nh5 14.Qe1 Ngf6 15.g4 Nxg4 16.fxg4 Bxg4 17.Nc3 Kd7 and the game is about even.

13...Be6

Fritz8 prefers 13...Nh5 14.Qd3 Ngf6 15.f4, giving White a small advantage.

14.h3 Bc4

Black needed to complicate things with something like 14...Nh5, for example 15.Qf3 (eye on the Knights!) Rf8 16.Qe2 (the same) Ngf6 17.e5 Kf7 (castling-by-hand!) 18.exf6 Nxf6 19.Re1 Qd7 20.Ne4 Kg8 and White is a pawn up, but things are still challenging: if 21.Nxd6 then 21...Bxh3.

15.Re1 Qd7 16.hxg4
Gathering in the wayward Knight.

16...Nxg4 17.f3 Nf6 18.e5 Nh5

19.exd6+

A bit better was 19.Qh4 Qf7 20.exd6+ Kf8 21.Re7 Qg6 22.d5, snaring the Black Bishop; but the text is sufficient.

19...Kf7 20.Qh2 g6 21.Re7+ Black resigned
