Nothing Much Happened

Sometimes when my opponent innovates against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I am content to take my opening advantage (in this case, a pawn or two) and slowly reduce it to an endgame advantage. In such games it seems like "nothing much happened" – only a win for White.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5


The Italian Four Knights Game.

5.Bxf7+


The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4


7...Nxe4


The same defense used by kfollstad earlier this year (see "Navigating on One's own"). It is at least as old as Alby - asalamon, FICS, 2000, which continued 8...Qh4 9.dxc5 Qxe4+ 10.Kf1 Qc4+ 11.Kg1 Qxc5 12.Qf3+ White resigned.

8.Nxe4 Be7

A new idea. Also possible was 8...d5.

9.dxe5 Re8 10.0-0 d6


11.exd6 cxd6 12.Bf4 Bf5 13.Nxd6+ Bxd6 14.Qd5+ Be6 15.Qxd6 Bc4 16.Qxd8 Raxd8


I have simplified the game: all Black has for his two missing pawns is the hope that he can make it to a drawish Bishops-of-opposite-colors endgame.

17.Rfe1 Rd4 18.Rxe8 Kxe8 19.Be3 Rd7 20.b3 Be2 21.Bxa7 Bd1 22.c4 Rd2


23.Kf1 Bc2 24.Be3 Bd3+ 25.Ke1 Re2+ 26.Kd1 h6 27.Rc1


Sloppy play, as Black can now capture the a-pawn, reducing White's advantage. Instead...

27...Kd7 28.Rc3 Black resigned

Navigating On One's Own

"There I was, minding my own business, playing a Jerome Gambit variant, when my opponent goes all 'creative' and gets himself a lost game... Worse yet, he dragged me along with him into the wilderness!"

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 


The Italian Four Knights Jerome Gambit, a version of the "modern" Jerome Gambit by transposition (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 Nf6).

5...Kxf7 6.Nxe5+ Nxe5 7.d4


7...Nxe4

Okay...

I'm not sure if my opponent borrowed this idea from the "fork trick" that shows up in the Italian Four Knights Game – 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bc4 Nxe4 5.Nxe4 d5 – or if he just decided to throw some material back at me.

Objectively better was 7...Bd6 8.dxe5 Bxe5.

8.Nxe4


Too Jerome-ish was 8.Qh5+ g6 9.Qxe5 Nxc3 10.bxc3 Bd6 11.Qd5+ Kg7 12.0-0 c6 13.Qc4 b5 14.Qd3 Qf6 15.c4 bxc4 16.Qxc4 a5 17.Bb2 Ba6 18.Qb3 Bxf1 19.Kxf1 Rhe8 20.Qb7 Qe7 21.d5+ Kg8 22.Qb3 c5 23.Qc3 Be5 24.Qa3 Bxb2 25.Qxb2 Qe2+ 26.Kg1 Qe1+ 27.Rxe1 Rxe1 checkmate, yorgos - jkpasanen, FICS, 2009.

8...Qh4

A better move was 8...Bxd4 as in 9.Qxd4 d6 10.f4 Nc6 11.Qd5+ Be6 12.Ng5+ Qxg5 13.Qxe6+ Kxe6 14.fxg5 Kd7 15.0-0 Rhf8 16.Bf4 Nd4 17.c3 Ne2+ 18.Kh1 Nxf4 19.g3 Nd3 20.Kg2 Nxb2 21.Rab1 Nd3 22.Rxb7 Rxf1 23.Kxf1 Rf8+ 24.Ke2 Nc5 25.Rxa7 h5 26.a4 Rf5 27.h4 Kc8 28.Ra5 Kb7 29.Rb5+ Kc6 30.Rb4 Re5+ 31.Kf3 g6 32.Kf4 Rf5+ 33.Ke3 Na6 34.Rc4+ Rc5 35.Re4 Rxc3+ 36.Kd4 Ra3 37.Re6 Rxa4+ 38.Ke3 Nc5 39.Rxg6 Re4+ 40.Kf2 Rg4 41.Rh6 Ne4+ 42.Kf3 Kd5 43.Rxh5 c6 44.Kxg4 Nf2+ 45.Kf3 Black resigned, yorgos - josephjorkens, FICS, 2009.

9.Nxc5

The other capture of the Bishop led to disaster: 9.dxc5 Qxe4+ 10.Kf1 Qc4+ 11.Kg1 Qxc5 12.Qf3+ White resigned, Alby - asalamon, FICS, 2000.

9...Re8 10.dxe5


A move made with no more thought than "Yippie! I get another piece!"

Simply castling was safer and smarter.

10...Rxe5+ 11.Be3

Guarding the Knight, but leaving the Bishop unguarded. Instead, 11.Kf1 Rxc5 gave White an even game – the best that I could hope for at this point.

11...Rxe3+ 12.Kf1 Re5 13.Nd3 Rf5


Black has the edge now, due to better development and a Bishop vs White's Knight. I guess kfollstad's creativity worked for him, after all.

14.Qe2

I was amused to see after the game that Rybka suggested further castling-by-hand for White: 14.h3 d6 15.Kg1 Be6 16.Kh2.

14...d6 15.Re1 Bd7


16.g3 Qd4

Too cooperative: 16...Qh3+ kept the advantage for Black.

17.Qe7+ Kg6 18.Qxd7


18...Raf8 19.Qe6+ Kh5



20.Nf4+ Rxf4 21.gxf4 Rxf4 22.Qh3+ Kg5 23.Rg1+ Rg4 24.Qxg4+ Black resigned

Still Playing That Opening?

I keep playing this Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) variant – and keep not liking it.

Why?  I'm 5-0-2 with it, which is respectable. Oh – I'm only 5-4-0 in the lines with ...h6 and 0-0 added (which should benefit White).

Maybe that's it??   

More likely it's because I need more "help" than usual from my opponents in this line in order to be successful.

Someday I'm going to face the line recommended by Rybka after the game: 7...Bd6 8.dxe5 Bxe5 9.Ne2 c6 10.f4 Bc7 11.e5 Ne4 12.0-0 d5 13.Be3 Re8 14.Nd4 Kg8 15.Rc1 g5




analysis diagram







This doesn't look comfortable for White.

8.Qxd4 Qe7


Well, this is no bed of roses, either, White having a pawn for his sacrified piece. What's a Gemeinde member to do?

9.f4

An alternative was 9.Bg5 Re8 10.Nd5 Qd6 11.0-0-0 Nxd5 12.exd5 Qg6 13.Qf4+ Kg8 14.Rde1 d6 15.h3 Rf8 16.Qe3 Bf5 17.f4 Nc4 18.Qc3 Nb6 19.Qxc7 Rac8 20.Qxb7 Rxc2+ 21.Kd1 Qh5+ 22.g4 Qf7 23.Qxf7+ Rxf7 24.gxf5 Rxb2 25.Rhg1 h6 26.Bxh6 Kh7 27.Bg5 Rxf5 28.Kc1 Rxa2 29.Re6 Rxd5 30.Re7 Ra1+ 31.Kb2 Rxg1 32.Bf6 Rg3 33.h4 Rd2+ 34.Kc1 Rh2 35.Bd4 Nd5 36.Re1 Nxf4 37.Be3 Nd3+ White resigned, Alby - roosje, FICS, 2000

9...Nc6 10.Qd3


After the game Rybka recommended, instead, 10.Qc4+, but after 10...d5 11.Nxd5 Qxe4+ 12.Qxe4 Nxe4 it is hard to get excited about White's position.

10...d6 11.0-0 Bg4


Black plans on returning the piece for a couple of pawns.

12.h3 Bh5 13.g4 Bxg4 14.hxg4 Nxg4


15.Qg3 h5 16.Bd2 Raf8 17.Rae1 Ke8


Each side is gathering its forces. Black is better, but his King remains a target, and the position is not simple.

18.Nd5 Qd7 19.Bc3 Rhg8

Getting the Rook off of the a1-h8 diagonal that the White Bishop just moved onto. Moving the King out of the center, instead, with Ke8-d8-c8 was probably a bit better.

20.e5

After the game Rybka preferred a long-winded line leading to a draw: 20.Qh4 Nf6 21.Kf2 Qf7 22.Nxf6+ gxf6 23.Rh1 Qxa2 24.Qxh5+ Rf7 25.Bxf6 Qc4 26.c3 Qd3 27.Reg1 Rxg1 28.Rxg1 Qd2+ 29.Kf3 Qd3+ 30.Kf2 Qd2+ etc, drawn by repetition.




analysis diagram







20...dxe5 21.Rd1


The move 20.e5 was a mis-calculation that I caught and tried to correct with 21.Rd1. Of course, it is possible to mis-understand my moves, and look at 20.e5 as a tricky sacrifice of a pawn, to open up lines toward the enemy King...

...In which case, that might cause a certain amount of (unnecessary) anxiety, and even provoke a quick defensive move that has a flaw in it.

21...Qe6

Ouch.

Rybka shows that Black can weave his way through the complications to a better endgame, although from a practical point of view, White may have drawing chances there (Bishop vs Knight, useful King placement): 21...Ne7 22.Ne3 Qe6 23.Nxg4 exf4 24.Rxf4 Rxf4 25.Qxf4 Qxg4+ 26.Qxg4 hxg4 27.Rd4 g3 28.Rd3 Nf5 29.Be5 Ke7 30.Bxc7 Rc8 31.Rc3 Kd7

Am I smarter than a fifth grader?

I've never seen the show "Are you smarter than a fifth grader?" but I suspect that I know the answer, and it wouldn't be a flattering one...

The following game, another bizarre Italian Four Knights Jerome Gambit (why am I still playing this opening??), I get befuddled, as usual, and wind up taking refuge in a draw by repetition.

The Bishop did better to return to e6. Still, Black is still better.

11.Be3 b6 12.0-0 Rb8


I wasn't sure what my opponent was planning with this move, but I decided to get my "Jerome pawns" moving.

13.g4 Bg6 14.g5 Nh5 15.f4 Nc6 16.f5


16...Nd4

Leading to only a slight disadvantage, instead, was 16...Kg8 17.fxg6 hxg6 18.a3 Kh7 – an odd way to castle-by-hand.

17.fxg6+ Kxg6 18.Qg4


Later, Rybka preferred 18.Qd3

18...Rf8


After this move, Rybka saw Black as being more than a Rook worse. I still can't see that.

19.Bxd4

Returning the game to even. Here's Rybka's recommended line: 19.Nd5 Re8 20.Nf6 Nxf6 21.gxf6+ Kf7 22.fxg7+ Ke7 when 23.Bg5+ wins Black's Queen – for starters.




analysis diagram







Anyone who saw White's possible Knight maneuver and sacrifice – good for you!

19...cxd4


Black insists on getting into trouble – 19...Qxd4+ would have kept the game even.

20.Qe6+

White, in turn, keeps insisting on giving up his advantage, instead of playing the winning: 20.Rxf8 Qxf8 21.Nd5 – another cool Knight move that I missed.




analysis diagram







20...Kxg5 21.h4+


I figured that there had to be a checkmate here, but I was wrong: Rybka pointed out later that I could have (should have) grovelled for a draw with: 21.Rxf8 Qxf8 22.Rf1 Qd6 23.Rf5+ Kh4 24.Rxh5+ Kxh5 25.Qh3+ Kg6 26.Qf5+ repeating the position.

21...Kxh4 22.Qe5


I suddenly had the feeling that things had gone terribly wrong.

They had.

22...dxc3 23.Qh2+ Kg5 24.Qe5+ Kh4


Of course, if my opponent had found 24...Kg6 here, I'd have been ruined. He seemed caught up in my "brilliant" sacrifice of my Knight to achieve the draw, or perhaps he felt he was escaping mate...

25.Qh2+ Kg5

Here 25...Kg4 wins for Black.

27.Qh2+ Kg5 28.Qe5+ Kh4 29.Qh2+ Game drawn by repetition ½-½
