The Jerome Gambit

Monday, March 11, 2013

Received Wisdom?

While it is interesting to look over the Jerome Gambit lines selected by the ChessBase "Opening Report" (the last three posts) based upon the games in The Database, it is important to remember that the collected "wisdom" presented is drawn from mostly amateur play - what is popular may not be what is "best".

History can be misleading.

For example, the main line of play, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 has always seemed to me to be easier for White to play (if subjectively less scary for Black to endure) than the lines after 6...Ke6.

Furthermore, do not be impressed by the "100%" score for White that shows up for the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.f4. After 6...Qh4+ 7.g3 Qg4 8.Qxg4 Nxg4 White will have a hard time whipping up any kind of attack with Queens off of the board and only two pawns in return for his two sacrificed pieces.

Finally, the recommendation for Black after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.0-0 - 6...Nc6 - Allows 7.Qh5+, winning the defender's dark-squared Bishop. Better is 6...Qf6, as 7.d4 is no threat, easily answered by 7...Bxd4! since 8.Qxd4 would lose to 8...Nf3+.

The Wisdom of The Database (Part 4)

We continue (see the earlier "Opening Report" parts 1, 2, and 3) to uses ChessBase's Opening Report function to take a look at the games in The Database.

As a reminder, the Report gathers what lines are being played, and what lines are being used by the top players in the database. It gives a good "real life" view of the play of the Jerome Gambit, even if it does not always identify the objectively best move or line.

The Wisdom of The Database (Part 2)

Sunday, March 3, 2013

The Wisdom of The Database (Part 1)

It's time again (see the earlier "Opening Report" parts 1, 2, and 3) to use ChessBase's Opening Report function to take a look at the games in The Database.

The Report gathers what lines are being played, and what lines are being used by the top players in the database. It gives a good "real life" view of the play of the Jerome Gambit, even if it does not always identify the objectively best move or line. (That would require a process called backsolving, which is not available in my ChessBase8.)

The Opening Report again also highlights a number of games from an interesting 2008 30-game human vs computers match (starting with "Jerome Gambit: Drilling Down (1)"

This post starts an extended series (which may be interrupted from time-to-time for news, games or analysis) wherein the intrepid "RevvedUp" (a good chess player) and his trusted companions Hiarcs 8, Shredder 8, Yace Paderborn, Crafty 19.19 and Fritz 8 explore the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) by taking turns playing the White and Black pieces.

The human moves first, and takes notice of the defense the computer plays. In the next game, where he moves second, the human plays that defense against a new computer – and sees how it attacks. In the third game, the human plays the recent attack against his new computer foe. Collectively, the players drill deeper and deeper into the Jerome Gambit.

And then what...?

As a therapist in my "day job" I often have the opportunity to help my clients expand their understanding of consequences of behaviors by asking them to look further: "And then what...?"

In the following game Black does a good job of defusing the primar threat behind White's 6th move, but he then becomes lax at just about the time he should have asked himself "And then what...?"

Wall,B - Guest1459913
Playchess.com, 2013

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

5...Kxf7 6.Qe2

A quiet move that you can find in a number of Bill's Jerome Gambit games.

6...d6

Dodging the misfortunes of 6...h6 7.Qc4+ in Wall,B - DarkKnight, Cocoa Beach, FL 2012 (1-0, 23); 6...Rf8 7.Qc4+ in Wall,B - Roberts,C, Chess.com, 2010 (1-0, 17), Wall,B - Hamilton,E, FICS, 2011 (1-0, 22) and Wall,B - NFNZ, FICS, 2011 (1-0, 15).

An alternate was 6...d5 as in the rare Wall,B - Samvazpr, Chess.com, 2010 (0-1, 25)

7.Qc4+ Be6?

You can almost read Black's mind: I took care of that move with 6...d6. Now I strike back by attacking the Queen with my Bishop!

8.Ng5+

Oh, well, yes, there is that...

8...Kg6 9.Nxe6 Qd7

10.f4

Threatening 11.f5+ Kf7 12.Nxc5+, winning the Queen.

10...h6 11.fxe5 Nxe5 12.Nxc5 Nxc4 13.Nxd7 Nxd7 14.d3 Nce5 15.0-0 c6

Players like myself (and perhaps Guest1459913) are often relieved, if not downright hopeful, when we find ourselves facing a strong player like Bill, being "only" a pawn down - with Queens off of the board, to boot.

This is usually an error in thinking: strong players can wield that extra pawn the way ordinary players wield an extra piece.

16.h4 Rhf8 17.Bd2 Kh5 18.Ne2 Kxh4 19.Nd4 g5 20.Nf5+ Kh5 21.Nxd6 b6

In case anyone is paying attention, White now has a protected passed pawn.

22.d4 Ng4 23.Nf5 Kg6? 24.Ne7+ Kh5

25.Nxc6

This wins another pawn, although Bill points out that 25.Rf3! was stronger.

25...Ndf6 26.Bb4 Rfc8 27.Ne7 Rxc2? 28.Rf3

Threatening 29.Rh3 mate

28...Ne3 29.Rxe3 Rxb2 30.Rh3+ Kg4 31.Rf1 Nxe4 32.Nd5 Re2 33.Ne3+ Rxe3 34.Rxe3 Ng3 35.Rff3 Nh5 36.Bd6 Rd8 37.Re4+ Nf4 38.Bxf4 Black resigned

Fish Fry

I just played my first blitz Jerome Gambit in a few months, and am again amazed that it seems the more I study the opening (to prepare these posts) the worse my chess play seems to get. (Detractors can laugh here.) Having staggered through a blunder-fest to reach a R+P vs R+2Ps endgame which I drew as time was running out on both myself and my opponent (the game has been discretely inserted into The Database), I again wondered if I finally needed to take up playing the Catalan...

Nah. Where's the fun in that?
