Patient Development



Here is an interesting game from the Chess.com "Kentucky Opening" (Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) tournament mentioned a couple of days ago. It shows that White's patient development, with a little bit of help from Black, can yield acceptable results.

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6


One of many reasonable ways to meet the Jerome Gambit, based on the idea of returning one of the two sacrificed pieces.

8.Rf1 g6 9.Qh3+ Ke7 10.Nc3


Houdini sees as a bit better, still leading to an advantage for Black, a slightly different move order: 10.fxe5 Qxe5 11.Qf3 Nf6 12.Nc3 c6 13.Ne2 Rf8 14.d4 Bxd4 15.Bf4 Qxe4 16.Qxe4+ Nxe4 17.Nxd4 g5 18.Be3 Rxf1+ 19.Kxf1 d5

10...c6 11.fxe5 Qxe5 12.d3


A bit stronger, according to Houdini, was the interesting 12.d4, i.e. 12...Bxd4 13.Bf4 Qe6 14.Qf3 Bg7 15.0-0-0 Ke8 when Black is still for choice.

The basis of hope for White is clearly seen after the text, though, in Black's lagging development and centralized King.

12...d5 13.Qh4+ Ke8 14.Bf4 Qe6 15.0-0-0 d4 16.Qf2 b5 17.Kb1 Bb6


Small inexactitudes on Black's part have brought the game to about even. The second player must be careful, as he is still undeveloped and his King is still at risk. 

18.Ne2 c5

Houdini takes a long look at a way for Black to keep the game even: 18...Nf6 19.h3 Nd7 20.Nxd4 Qf7 21.e5 Qd5 22.Be3 Bxd4 23.Bxd4 Qe6 24.Be3 Bb7 25.Rde1 Rf8 26.Qh4 Rxf1 27.Rxf1 h5 28.g4 c5 29.gxh5 gxh5 30.Qxh5+ Kd8 31.Rf7 Bd5 32.Bg5+ Kc7 33.Re7 Bxa2+ 34.Kc1

19.Bg5 Ne7 20.Nf4 Qf7


Black's extra material does him no good, parked in the garage.

21.Qe2 Qg7 22.Nd5 Bd8

A final (un-developing) slip.

23.Nf6+ Black resigned

A Look At A Rare Beast

The Jerome Gambit is not a drawish opening. Only 3% of the Jerome Gambit games in The Database are draws. Only 3 of the completed games in the current ChessWorld Jerome Gambit Thematic Tournament have been drawn. It would seem, therefore, that splitting the point would be difficult, but the following game argues against that: White sacrifices a piece, Black gives it back, they draw. Q.E.D.

Rikiki00 - shm19cs
ChessWorld, Jerome Gambit Thematic Tournament, 2011

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


4...Kxf7 5.d3

One of the "modern" (non 5.Nxe5) Jerome Gambit lines.

5...h6 6.0-0 d6 7.Nc3 Bg4 8.h3 Bh5 9.Be3 Nd4 10.Bxd4 Bxd4 11.Nxe5+ Bxe5 12.Qxh5+


White has grabbed a second pawn as partial compensation for his sacrificed piece.

12...g6 13.Qf3+ Kg7 14.Rad1 c5 15.Nd5 Qd7 16.c3 Rf8 17.Qe3 Nf6 18.Nxf6 Rxf6


A slip that forces Black to return the piece.

19.f4 Rhf8 20.fxe5 Rxf1+ 21.Rxf1 Rxf1+ 22.Kxf1 dxe5


White's extra pawn does not mean a lot.

23.Ke2 b6 24.Qf3 a5 25.Qg3 Qe6 26.b3 b5 27.Ke3 Qd6 28.Qg4 b4 29.cxb4 axb4 30.Qe2 Qd4+ 31.Kf3 Kf6 32.Qc2 draw

My Old Kentucky... Opening

Anyone familiar with the Kentucky Derby horse race has heard Stephen Foster's "My Old Kentucky Home", its official song.

Many chess players familiar with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) know that it was referred to by Joseph Henry Blackburne as "The Kentucky Opening".

Blackburne's reference is a bit obscure, but less so since the advent of this blog: see "The Kentucky Opening" parts 1, 2, 3, 4 and "The Kentucky / Danvers Opening".

In any event, I recently stumbled upon a Kentucky Opening /Jerome Gambit tournament played at Chess.com. The tournament is interesting in a number of respects, not the least of which is the winner, GazzaT, was rated 2468.

So, in addition to monthly samplings from FICS, and the games from the ongoing ChessWorld Jerome Gambit Thematic Tournament, I now have Chess.com games to share with readers!

That is a lot to be thankful for.

One More Thing...

As an addendum to yesterday's post (see "Do Not Wander Too Far From Home"), when considering a risky line (for Black) in the Jerome-ized Italian Gambit, White, too, must make the right move.

augmented - MAHG
standard, FICS, 2011

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


4...Kxf7 5.d4 Nxd4 6.Nxe5+ Ke6


The same adventurous stroll as in Darrenshome - WildErmine, blitz, FICS, 2006.

7.Bf4

The direct route to the finish line is 7.Qg4+, as we saw yesterday.

7...d6

Instead, backing the King away with 7...Ke7, or preparing for that move with 7...Nf6, each let Black keep his advantage.

Now White can checkmate.

8.Qg4+ Ke7

8...Kf6 9.Bg5+ Kxe5 10.f4+ Kxe4 11.Nc3+ Ke3 12.f5+ Qxg5 13.Qxg5#

9.Qxg7+ Ke8 10.Qf7 checkmate

Do Not Wander Too Far From Home

Yesterday's post (see "Still An InterestingGame") got me thinking about an early d2-d4 for White in the Jerome Gambit and related openings. That, in turn, got me thinking about the Italian Gambit (see "Brilliant but not sound" too) and helped me turn up the following game. 

Darrenshome - WildErmine
blitz, FICS, 2006

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d4


The Italian Gambit. 

All three of Black's captures of the d-pawn can lead to a roughly equal game, but the second player should remain attentive.

4...Nxd4 5.Bxf7+

Transposing to the Jerome Gambit, i.e. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4 Nxd4.

5...Kxf7 6.Nxe5+ Ke6


Black either does not believe in what he sees, or he is careless and does not watch where he is going. In either event, it is risky to wander too far from home...

7.Qg4+ Kxe5 8.Bf4+ Kxe4 9.Nc3 checkmate

Still An Interesting Game



Here is the latest Jerome Gambit game from Bill Wall, who writes
After seeing your article on Utterly Fascinating, I decided to play the 5.d4 line as well, but my opponent took with the bishop instead of the pawn. Still an interesting game.

notes by Bill [comments by Rick]


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


4...Kxf7 5.d4!?


[The Database has over 1500 games with this move. White scores 38%. Also check out "A Closer Look At the Big Picture (Part 3)"]

5...Bxd4

This may be better than 5...exd4

[See "Brilliant but not sound".]

6.c3 Bc5?

This gives me the piece back.

6...Bb6 should be played, then I may play 7.Qb3+.

7.Qd5+ Ke8 8.Qxc5 Qe7


9.Qc4 Nf6 10.0-0 d6 11.Be3 Be6 12.Qb5 Qd7


12...Nxe4 13.Qxb7

13.Ng5

13.Qxb7 Rb8 14.Qa6 Rxb2

13...a6?!

Now not as effective as I will have more threats and win another pawn; perhaps 13...Nd8

14.Qxb7 Rb8 15.Qxa6 Ke7


Not 15...Rxb2 16.Nxe6 Qxe6 17.Qxc6+ winning a piece.

16.Nxe6 Kxe6 17.Qc4+ Ke7 18.a4

Passed pawns must be pushed.

18...Rxb2 19.a5 Ra8 20.a6 Ng4 21.Bg5+ Nf6


Not 21...Ke8?? 22.Qg8#

22.Nd2 h6 23.Bxf6+ gxf6 24.Nf3 Rb6


25.Nh4 Qe6 26.Nf5+ Kd7 27.Qd3 h5 28.Ne3 Qb3 29.Nd5 Qb5


30.Qh3+! Kd8 31.Qe6 Rbb8 32.Qg8+ Kd7 33.Qf7+ Kd8 34.Qf8+

34.Nxf6 may have been quicker, but I was in time pressure with 30 seconds left.

34...Kd7 35.Qg7+ Kd8 36.Nxf6 Ne7 37.Qf8+ Qe8 38.Qxe8 checkmate
