Jerome Gambit: More Videos

When I mentioned the video "Is Jerome Gambit Sound?" April 5,  a few posts ago, I neglected to list the three other Jerome Gambit videos that Mato Jelic had posted earlier at YouTube.

They were pointed out to me by Roland Kensdale at the English Chess Forum.

"Must See Jerome Gambit" concerns the game "NN vs Blackburne, England, 1880" - the best-known and most exciting Jerome Gambit. (As we have only very recently learned, the year was more likely 1884).

Check out also "The Birth of  Jerome Gambit", focused on "Alonzo Wheeler Jerome vs William A Shinkman, correspondence 1874". This is the earliest game that I have a score of, although Jerome, himself, said he first played his gambit against G.J. Dougherty.

The "Practical Application of Jerome Gambit" features the game "Bill Wall vs Itboss , Online, 2016" 

All of Mato Jelic's videos are great fun and well worth viewing.

Jerome Gambit: Eyes on the King

After all is said and done, in the Jerome Gambit White wants to attack and checkmate Black's King. Sometimes that is goal enough.

When White Equalizes in the Jerome Gambit, He Has the Advantage

Knowing the Jerome Gambit well gives the attacker several advantages, including the ability to "make something out of nothing" because of his understanding of typical play. Too, there is a danger for Black that, having reached an "even" position, he might lessen his attention - and invite disaster.

Black has returned the sacrificed piece for what he believes is an equal game.

He has forgotten the old saying: When White equalizes in the Jerome Gambit, he has the advantage. How else to explain the quick end to the game?

14.Qg3 Qd4+ 15.Kh1 Ba6 16.Bh6 

A nice sacrifice that moves the advantage in White's direction.

16...gxh6 17.Rad1 Qg4 

Black had to try 17...Bxf1 18.Rxd4 Bxg2+, although White would still have an edge after 19.Kg1!?

Now Black loses his Queen, and checkmate is forced.

Philosophy and the Jerome Gambit

Oh, my.

Bill Wall just sent me his latest Jerome Gambit game and I wrote back and said it was an example of "existential chess".

I was thinking about the idea of a "negative halo effect" that I had touched on in earlier posts (see "Halo Effect", "Feeling Lucky", "Kick Me" and "Dizziness Due to Success"). I mean the perception that if one starts a game with the "wrong" opening then one can be expected to continue to produce "wrong" chess and the whole game can be expected to be equally "wrong".

How dare Bill, instead, follow up with strong play, avoid missteps and win with a mating attack??

It reminds me of a quote from Justin E. H. Smith's essay "The Flight of Curiosity"

To take an interest in that false belief is not to reject the truth, but only to wish to fill out our picture of the truth with as much detail as possible, and not because of some aesthetic inclination to the baroque, but rather because false theories are an important part of the puzzle that we ... should be trying to complete: that of determining the range of ways people conceptualize the world around them.

White has only a pawn for his sacrificed piece. However, beyond the "theory of infinite resistance" this particular White has a lot of experience (over 400 games in The Database, for example) and if there are tricks, traps or nuances to be exploited, he will know about them or be ready to find them.

A bit of a better choice for Black is 16...Be6, when either  17.Bxf6 or 17.Qxb7 dxe5 18.fxe5 Nxe5 19.Bxf6 gxf6 would be good for him; although the draw with 17.Qa4 Bd7 18.Qb3 Be6 19.Qa4 etc might arise.

18...Bd7

Instead, 18...Nxe5 19.Rxe5 Qd7 20.Bxf6 Qxa4 21.Nxa4 gxf6 22.Rc5 c6 23.Rxf6 looks about equal.

22...Bf5 

Time to give some material back, but not 22...Kh8 23.Qg6 Nf5 24.Rxf5 Bxf5 25.Qg7 checkmate 

23.Rxf5

Bill gives the alternative 23.f7+ Kxf7 24.Rxf5+ Nxf5 25.Qxf5+ Kg7 26.Rd7+ Qxd7 27.Qxd7+ and White would also be better.

23...Nxf5 24.Qxf5

Kf8 28.Qg7+ Ke8 29.Qe7 checkmate

What Happened??

Black plays reasonable chess in the following game, as does White - who slowly moves the game toward equality. Then, suddenly, the second player deliberately hangs a piece, and White's attack on the enemy King crashes through. Can Readers uncover an explanation (other than "chess blindness") for Black's 17th move?

Meeting A Threat With A Threat

In analyzing tactics for a position, players are encouraged to not just find a defensive solution, but to look for a possible counter-threat that would grab the initiative and force their opponents to defend their threats.

This idea of "meeting a threat with a threat" is clearly on the mind of Bill Wall's opponent in the following game. It is interesting to watch Bill meet the new threat with another one of his own - with telling effect.

8...Nf6 9.Nc3

Instead, 9.f4 was seen in Jerome,A - Shinkman,W, Iowa, 1876  (½-½, 42).

Earlier, Bill had played 9.f3, i.e. Wall,B - Guest903719, PlayChess.com, 2013 (1-0, 47).

Black continued without this "kick", with 10...Nc6, in perrypawnpusher - JoseSoza, Chess.com, 2012 (0-1, 34). 

11.Bh4

Bill notes, as an alternative, 11.Bxf6 Qxf6 12.Rad1 Nc6 13.Qc4+ Be6, which may be less strong than the text. 

11...Be6

Black could also have castled-by-hand with 11...Kg8.

12.f4 c5

Black decides to "meet a threat with a counter-threat", but the straight-forward 12...Nc6 was better. 

13.Qa4 Ng6

Black retreats with a threat, but he has missed one of those by White.

14.Bxf6 gxf6 15.f5 b5

Again, Black conters a threat with a threat, but simpler would have been 15...Kg7 16.fxe6 Rxe6 17.Qb3, although White would be better. 

16.Qxb5 Bd7 17.fxg6+ Kxg6 18.Qd3 Kg7

The smoke has cleared, and White has an extra pawn.

Equally 21.Rxf6 Qxf6 22.Qxc7. 

21...Kh7 22.Nd5 Rc6 

23.Nxf6+ Rxf6 24.Rxf6 Qxf6 25.Rxd7+ Black resigned.

White is ahead three pawns, and Black has no counterplay.

A-Maze-Ing

In the following game Bill Wall changes up his Jerome Gambit attack, playing 6.d4, the favorite move, at first, of Alonzo Wheeler Jerome. Can his opponent follow him through the maze?

Wall,B - Guest4060198 
PlayChess.com, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 

6...Qf6

The more straight-forward 6...Bxd4 was seen in Wall,B - berserkergang, FICS, 2011 (1-0, 21) and Wall,B - Guest903719, PlayChess.com, 2013 (1-0, 47), as well as the seminal Jerome,A - Shinkman,W, 1876, (½-½, 42).

The trickier 6...Bb4+ was seen in Wall,B - ChrSav, FICS, 2010 (1-0, 11);  Wall,B - Caynaboos, FICS, 2011 (1-0, 26); Wall,B - ChessFlower, PlayChess.com, 2012 (27);  and Wall,B - Boris, SparkChess.com, 2012 (1-0, 31).

The questionable 6...Nf3+ was seen in Wall,B - Guest151963, PlayChess.com, 2011 (1-0,17).

6...Qh4, probably Black's strongest reply, was seen in Wall,B - Rajiv, Chess.com, 2010 (1-0, 33); Wall,B - Gorodetsky,D, Chess.com, 2010 (1-0, 18); and Wall,B - felineMMXI, blitz, FICS, 2011 (1-0,18).

7.dxc5 Ne7 8.0-0 Rf8 9.Nc3 c6 

Black would do better to follow through on his plan to castle-by-hand: 9...Kg8 10.f4 Nf7. The problem seems to be that he is trying to do too many good things at once - play ...Qf6, safeguard his King, hit back in the center with ...d5.

10.f4 N5g6 11.Be3 d5? 12.cxd6 Ng8 

The "Jerome Pawns" are a scary sight.

13.d7 Rd8

A bit better (but not much) was 13...Bxd7 14.Qxd7+ N6e7.

14.dxc8/Q Raxc8 15.Qh5

Threatening 16.f5. White is up two pawns, with the initiative. 

15...Kf8 16.e5 Qf7 17.f5 Nxe5 18.Bc5+ Ne7 19.Qxh7 Qf6 20.Ne4 Qh6 21.Qxh6 gxh6 22.f6 Black resigned

No matter how he struggles, Black is going to lose a piece and a Rook. Amazing.

Who's the "Expert"?

The following game made me wonder, who knows the Jerome Gambit better, him or me? The outcome was surely suggestive!

perrypawnpusher - vz721
Italian Game thematic, Chess.com, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 Nf6 11.d3

I have sometimes referred to this as the "optical illusion" variation (see here and here for starters) because of the number of times in blitz play that my opponents have relaxed and allowed me to pin their Queen to their King.

In the April 1874 issue of the Dubuque Chess Journal, Alonzo Wheeler Jerome wrote that 11.d3 compelled either King or Queen to move as White threatens Bf4; or Black can play ...g5. 

He was referring to the game Jerome - Shinkman, Iowa, 1874, which appeared in the July 1874 issue of the DCJ, and indeed, the game continued 11...Ke7 12.Nc3 g5; although after White's 21st move he wrote "and Mr. Shinkman announced loss of the Queen or mate in six moves." Ouch.

11...Ke7 12.Nc3 d6 13.Bf4 

So far, following Jerome - Brownson, Iowa, 1875, (1-0, 43).

13...Qh5

An interesting improvement on Brownson's 13...Qe6, which allowed Jerome to play 14.0-0-0 and then meet 14...Qg4 with 15.Qf1. White doesn't have a great position, but he keeps the Queens on the board.

14.0-0-0 Qxf3 15.gxf3 Be6 16.d4 Bb4 

At first I was happy with my pawn center. It grabs space, and threatens to advance, feeding an attack on the King. However, I decided to "hold" the center, instead, and my pawn chain became frozen - and my opponent started hammering it.

17.d5 Bf7 18.Nb5 Kd7 19.Nd4 Rae8 20.Nf5 Rhg8

21.h4 Bg6 22.Nd4 Nh5 23.Bh2 Bc5 24.Rhe1 Bxd4 25.Rxd4 Rgf8 

All the "dynamic" aspects of the pawn center have been removed.

26.Rd3 Nf4 27.Rd2 Bh5 28.Re3 Ng6 29.Rf2 Nxh4 White resigned

I might have been able to get 30.f4 in here, but that was about as mobile as my center was going to get. It looked like nothing more than suffering to me, so I turned my  attention to my remaining games.

Very nicely played, Vlad!
