Jerome Gambit: History Reset

NN - Blackburne, London, 1884

The other day, I stumbled over a remark (from May 22, 2017) by zanzibar, at the Chessgames.com website. He was commenting on the (in)famous Jerome Gambit game,  NN - Blackburne, casual game, London, 1884, and noted
Fine uses a position from this game (p088, d135), after Black's 12th move, but omits the White queen on a8.
zanzibar was referring to Reuben Fine's The Middle Game in Chess (David McKay, 1952), the chapter on "The Mating Attack". After giving the diagram (see above), Fine wrote [descriptive notation changed to algebraic notation]
Blackburne also found the mate in diagram 135 during a blindfold seance. He played 1...Qxh3+!! 2.gxh3 Bxe4 mate
It is likely that, in his diagram, GM Fine left off White's Queen from a8, where it was placed in the game, for instructional purposes, as it arrived on that square after accepting Black's double Rook sacrifice, in the most scruffy of chess openings, where White had sacrificed two pieces - all too much distraction from the case at hand.

GM Fine's contention that the game was played blindfold also raises an eyebrow. The Illustrated London News' May 10,1884 account of the game makes no mention of Blackburne playing blindfold. Indeed, Mr Blackburne's Games at Chess (1899) places the game in the "Games Played Off-Hand, Simultaneously or at Odds" chapter, rather than the "Games Played Blindfold" chapter.

Interestingly, the Blackburne position in The Middle Game in Chess follows one given by Fine as
reached by Pillsbury in a blindfold exhibition 
What is a bit odd about this is that Pillsbury was, according to the diagram, playing the Black pieces - usually the blindfold player is given the White pieces. For example, Jaques N. Pope's Harry Nelson Pillsbury American Chess Champion (Pawn Island Press, 1996), contains almost 250 blindfold games, and Pillsbury has White in all but one of the games. While P.W. Sergeant and W.H. Watts, in their Pillsbury's Chess Career (American Chess Bulletin, 1922) suggest that "he must have played many thousands such games" - only one of their 44 blindfold games had Pillsbury with Black.

Fortunately, Pope comes to the rescue. On the first page of his "Other Games" chapter, he gives the following position, from which follows "a pretty combination he played as black in a knight odds game [emphasis mine] in 1899." Popes's reference is Vol. XIX, no. 22, November 25, 1899, the Literary Digest, which gives the piece placement in a "Pillsbury Brilliancy", describing it as coming from an
offhand game betwen Pillsbury and a strong amateur, the latter securing the odds of a Kt. 

Amateur - Pillsbury, 1899 (Kt odds)
 1...Qf7 2.Bxe4 Reaching the position that Fine started with in his diagram [descriptive notation changed to algebraic notation]. 2...Qf1+ 3.Bg1 Qf3+ 4.Bxf3 Bxf3 checkmate.

(I mean no offense to the memory GM Fine, whose chess set I would have been unworthy to carry. History needed a reset, and I've done it before.)

Jerome Gambit: Merry Christmas!

Image result for free clip art chess christmas


Here is my latest letter from Cliff Hardy - a Jerome Gambit game (time limit: bullet, one minute, no increment - in this game, about a second per move.) with a timely Christmas motif! I have added some diagrams, but the commentary is all his - Rick

Merry Christmas, Rick!

This game intrigued me as Black was unusual in being able to find the excellent 11...Kc6! move in this variation. Unfortunately, he was forced soon after that to become really generous this Christmas, as the presents began to be handed out...

Cliff Hardy (2286) - NN (2532)
1 0, Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ 

If you expect to receive presents, you should give some first!

5...Nxe5 6.Qh5+ Ke6 

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


11.d3 Kc6!

Very rare for someone to find this risky-looking but pugnacious move - and in bullet too!

12.Nc3

I'm never quite sure in this variation whether to play c3 or Nc3.

12...d5 13.Bf4 dxe4 14.dxe4 Qe6??


Black gives a Christmas present! 14...Qh5! -++, intending 15.e5+ Qxf3 16.gxf3 Nh5, would have been very strong for him.

15.0-0-0?? =

It's Christmas time and White proves to be very charitable! I didn't realise that 15.e5+ Nd5 ++- doesn't really hang in for Black e.g. 16.0-0-0 Rd8 17.Nxd5 Rxd5 18.c4, when the pinned Black rook will require wrapping paper and a gift tag.

15...a6?? ++- 

You know that moment at Christmas when you graciously refuse a Christmas present but the giver continually thrusts it upon you? A complex game would have arisen after 15...Qg4! 16.Qf1! (threatening checkmate in one with 17.Qb5#) 16...b6 =, when Black's exposed king compensates for White's sacrificed bishop.

16. e5+ Kb6 17. exf6 Qxf6??


Another present for me? Why, thank you! Stockfish rated the position before this move as lost for Black anyway, due to his exposed king, but I admit it all looked very unclear to me! Now though, it was fairly easy to take out the win and the rest of the game was uneventful.

18.Nd5+ Ka7 19.Nxf6 gxf6 20.Qc3 Bb6 


21.Be3 Bg4 22.Bxb6+ cxb6 23.Rd6 Bf5 24.Qxf6 Rhf8 25.Qd4 Rac8 26.Qxb6+ Ka8 27.c3 Be4 28.Rhd1 Bxg2 29.Rd8 Kb8 30.Rxf8 Rxf8 31.Rd8+ Rxd8 32.Qxd8+ Ka7 


33.Qd4+ Kb8 34.Qg7 Bc6 35.Qxh7 Ka7 36.Qh8 a5 37.h4 Kb6 38.Qd4+ Kb5 39.h5 a4 40.h6 a3 41.b3 Ka6 42.c4 Be4 43.h7 Bxh7 44.Qd5 Ka7 45.Qb5 Bg8 46.Qa5+ Kb8 47.Qd8+ Ka7 48.Qxg8 Kb6

Jerome Gambit: Descent Into Rubble

The latest game from Cliff Hardy is a wild affair, concluding with a mad dash to the finish line - er, time control. 

In a 1-minute, no increment, bullet game, you can win, even if your opponent has a forced checkmate - if his flag falls. Just another reason for an opponent to hate the Jerome Gambit.  

I have added some diagrams and a comment or two, in blue; otherwise, the notes are by Cliff. 

Here is a bullet Jerome Gambit game I played today, which most certainly has several errors in it!

Cliff Hardy (2400) - NN (2391)
1 0, Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 



7.Qxe5 Qe7 8.Qf4+

I successfully remembered that taking the rook here is inferior (I think!).

Black is playing Whistler's Defense with 6...g6 and 7...Qe7. Taking the Rook at h8 is complicated, but "theoretically" dangerous for White, although The Database shows a score of over 50% in about 50 games. Check out the earlier post, "Bop!" - Rick

8...Kg7 9.d3 Nf6 10.0-0 Rf8 

Black has effectively castled-by-hand. Given enough time, he will continue to figure things out. Unfortunately, he will not have enough time. - Rick

11.Nc3 d6?!


Stockfish prefers the hard-to-see 11...d5! -++ e.g. 12.exd5?/e5? Ng4! 13.Qg5 Bxf2+.

12.Qh4 Bd4? =+

Missing White's threat - 12...h5 13.Na4 -++ would still have been strong for Black.

13.Bh6+ Kg8 14.Bxf8 Qxf8 15.Kh1 Be6?! =


The perennial inaccuracy for Black in the Jerome Gambit - this bishop move tends to run headlong into White's pawn push f2-f4-f5. Better would have been 15...Qg7 16. f4 Bd7, with a slight advantage for Black. 

16.f4 Re8 17.Nd1? =+

17.Ne2 would have been better, though I had missed that 17...Bxb2? could then have been met by 18.Rab1.

17...Ng4 18.h3 Ne3 19.Nxe3 Bxe3 20.Rf3 Bd4 



21.c3 Bg7 22.Raf1 Qe7??


22...Qf6 23.Qf2 =+

23.Qg3??

Missing the typical Jerome Gambit tactic of utilising the f-pawn with 23.Qxe7 Rxe7 24.f5 gxf5 25.exf5 Bxa2 26.f6! ++-, forking the rook and bishop.

23...Bxa2 24.f5 Bf7??

The Jerome Gambit f-pawn strikes again! Blockading it with 24...gxf5 25.exf5 Qf6 would have left Black with a clear advantage.

25.f6 Bxf6 26.Rxf6 Be6 

27.Qf4 Kg7 28.Qf2 Bg8?

The interference tactic 28...Bf5! would have been better here, though after 29.Rxf5 gxf5 30.exf5 Rf8 31.Qxa7, White would still have had a winning advantage.

29.Rf3 Qe5 30.Qxa7 Qb5 

31.Qd4+ Kh6 32.Qf6 Re5 



33.Qh4+ Kg7 34.Qf6+ Kh6 35.Rf4 Rh5? 



36.Rh4?

Black made the mistake of allowing White to mate in 2 moves with 36.Qf8+ Kg5 37.Rg4 (which White obviously missed!), though Black's position was lost in any case.

 36...Rxh4 37.Qf8+?

The game now descends into rubble. With White having 2.4 seconds left on the clock and Black having double that (exactly 4.8 seconds left), we both started to throw down any move we could think of! Clearly, 37.Qxh4+ would have been a much better move to play (though even after 37.Qf8+?, White still has a winning position).

37...Kg5 38.Qf3 Rg4?? 39.Qg3?? Rxg3 40.Kh2 Qe5 41.Rf5+ and White cheekily won on time.

Jerome Gambit: Strong Attacking Position

Image result for free clip art attack


Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) will lead to tactical mayhem by White, and it is relatively easy - if still educational - for the observer to anticipate the line of play. Sometimes, however - as in the following game - the Jerome Gambiteer develops a strong attacking position, and he has to work out a series of moves to gather in the full point; then, the educational value of the game is even greater.

Wall, Bill - Anonymous
lichess.org, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Kf8 

I expected a rash of 5...Kf8 games after the post "Jerome Gambit: Success at Last (Sort of)" which featured a game where Bill surrendered a draw in the line - after 15 straight wins.

6.Nxc6

No more experimenting - Bill had tried 6.0-0 in his last game with the line, and, after 6...Nf6, continued with 7.Nd3. The text is probably strongest.

6...dxc6 7.O-O Qf6 

White has only scored 50% against this move, according to The Database - if you ignore Bill's two wins, against no losses, that is.

8.Nc3 Be6 

Or 8...Bd6 9.d4 h6 10.e5 Bxe5 11.dxe5 Qxe5 12.Re1 Qg5 13.Bxg5 Black resigned, Wall,B - NN, lichess.org, 2016, 

9.d3 Ne7 

Instead, 9...Rd8 let Black keep an edge, in Wall,B - Guest4658155, PlayChess.com, 2019 (1-0, 29).

10.Be3 Bb6 11.Qd2 h6 12.Rae1 Kg8 13.f4 Kh7


14.f5 Bd7

As will become clear, the Bishop was safer retreating to c8. Black has just connected his Rooks, however, and does not want to interfere. 

15.e5 Bxe3+ 16.Rxe3 

The position is complicated, and it is not a surprise that Black does not find a defense. The Black Queen may be relativelyt safest after 16...Qh4, but 17.e6 then threatens the Bishop, and White will build his attack when he can play f5-f6 and Ne4.

16...Qg5 17.Ne4 

The Queen is trapped.

17...Qh5 18.Rh3 Qe8 

Her Majesty has escaped, but His Majesty is doomed.

Jerome Gambit: Careless and Inefficient Defense

How many times have you read the caution that an advantageous chess position "won't win itself"? The same holds for a disadvantagous position - say, one that White has at the beginning of the Jerome Gambit. White's game "won't lose itself", either; Black has to make it so. In the following game, the defender slips into carelessness, becoming inefficient - and his game suffers. 

Wall, Bill - NN
Florida, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb6 



Black's move maintains his advantage. It is not as complicated as 6...Qh4, nor as simple as 6...Bxd4. There are 153 games with 6...Bb6 in The Database; interestingly enough, White scores 57%.

More importantly, Bill is 19-0 against the move.

7.dxe5 Ne7 8.Qf3+ Kg8

Bill has also faced 8...Ke8 9.O-O (9.Qg3 Ng6 10.Bg5 Ne7 11.Nc3 h6 12.Bd2 Rf8 13.O-O-O Rf7 14.e6 Rf6 15.Qxg7 Rxf2 16.Bxh6 d6 17.Qh8+ Black resigned, Wall,B - Guest2896104, PlayChess.com, 2019) 9...Rf8 10.Qh5+ g6 11.Qxh7 d6 (11...g5 12.Qh5+ Rf7 13.Bxg5 c6 14.Nd2 Qc7 15.Nc4 a5 16.Nd6+ Black resigned, Wall,B - WGMS, FICS, 2017) 12.Bh6 Rg8 13.Bg5 Be6 14.Nc3 Qd7 15.exd6 cxd6 16.Rfd1 Kd8 17.e5 Bc5 18.exd6 Bxd6 19.Ne4 Kc8 20.Rxd6 Qe8 21.Rxe6 Black resigned, Wall,B - Guest11863268, PlayChess.com, 2018. 

9.Qb3+ Kf8 10.O-O Ng6 



This is an improvement over 10...d5 seen in Wall,B - Guest6791785, PlayChess.com, 2018 (1-0, 17). 

11.Qf3+ Ke8

The better retreat. Black should not be hypnotized by the g8 square, as he is better in the game: 11...Kg8 12.Qb3+ Kf8 13.Qf3+ Kg8 will only draw.

12.Nc3 d6

Or 12...Rf8 as in Wall,B - Guest5463336, PlayChess.com, 2018 (1-0, 15). 

13.Nd5 Nxe5 14.Qg3 Ng6 



15.Bg5 Qd7 16.a4

White can afford to be patient: from a practical point of view, Black is hampered by his Queen blocking in his Bishop, which, in turn, restrains his Rook - a classic Jerome Gamit defender illness.

16...Rf8 17.a5 Bc5 

You've got nothing, Black likely thinks, and, as a result, he becomes careless and inefficient. The Bishop needed to go to d4, and then f6, directly.

18.b4 Bd4 19.Rad1 Be5

Giving away another free tempo.

20.f4 Bf6 21.Bxf6 gxf6 



22.Qc3

Double attacks on both c7 and f6.

My guess is that Bill passed on 22.e5 because after 22...fxe5 23.fxe5 dxe5 24.Nf6+ Black can take the annoying Knight with 24...Rxf6, when 25.Rxd7 Rxf1+ 26.Kxf1 Bxd7 would give Black a Bishop, a Knight and a Rook for his Queen. The position might well be "dynamically equal", but there was no need to find out, when the text was available.

22...c6 

The King had to go to d8 to protect the c-pawn.

23.Nxf6+ Rxf6 24.Qxf6 Qe7 25.Rxd6 Qxf6 26.Rxf6 Ke7 27.e5 Bd7

White has a Rook and 3 pawns for a couple of pieces. Those dangerous "Jerome pawns" give him the advantage.

28.Rd1 Be6 

A slip tht hastens the end.

29.f5 Nxe5 30.Rxe6+ Black resigned
