Jerome Gambit: White's Game Is In Its Last Throes (Again)

Image result for free clip art dying

According to the hypermodern player Gyula Breyer, after 1.e4 White's game is in its last throes.

Subsequently, many played 1.e4, and lost.

Of course, many played 1.e4, and won.

Chess is complicated like that. Even after you play the right, best move - you have to play another one, and another one, and then another one...

In the following Jerome Gambit game, Black plays a very promising 6th move, but his opponent does not oblige him by resigning. Instead, the game goes on, and before 20 more moves are played, it is Black who has to turn over his King. 

Wall, Bill - Mecnieri
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



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



The Database has 250 of Bill's games with this position. (White scored 91%.)

6...Qh4

Possibly Black's strongest reply - but only played against Bill 30 times. (White scored 85%.)

7.O-O Ng4 8.h3 Bd6 

The position looks scary for White.

9.e5 Nxe5 

"Scientifically" returning one of the sacrificed pieces for a couple of pawns. Bill pointed out the alternative 9...Be7 10.hxg4 d6 and Black is still better.

10.dxe5 Bxe5 11.Qd5+ 



11...Kf8 

Black returns the second sacrificed piece, but could well have played 11...Kf6 12.Re1 Bd4

12.Qxe5 d6 13.Qa5 Qe7



Material equality has been reestablished. White's King is safer, however. It is also good to remember the curious Jerome Gambit bromide: when White has equalized, he has the advantage. 


14.Nc3 Nf6 15.Nb5 c6 16.Nd4 h6 



Black moves to keep White's Bishop off of g5, but he doesn't have time for this.

17.Re1 b6 18.Qc3 Nd5 


A tactical slip. He would have done better with 18...Qd7

Now White puts on the pressure and wraps up the game.

19.Nxc6 Nxc3 20.Nxe7 Bb7 21.Ng6+ Kg8 22.Nxh8 Kxh8 23.bxc3 Black resigned


Everything looks pretty well balanced - until you notice that White is up a Rook.

Jerome Gambit: Quite Strange

Image result for looney tunes

The Jerome Gambit leads to some strange games. However, some games are stranger than others.

The following game is the strangest one that I have seen in a while.

Wall, Bill - Guest371494
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Nf6



So far, pretty "normal" - for a Jerome. Black's choice to keep developing and let White "waste" time recovering one of two sacrificed pieces is reasonable, if not best.

7.dxe5 Bxf2+ 

Black decides to return another piece, as well. Suddenly White's King is exposed.

8.Kxf2 Nxe4+ 9.Ke1 

The position is kind of strange - but not unknown. In fact, it is difficult to find a line that is totally unfamiliar to Bill. For example, previously he has played:

9.Kg1 Rf8 (9...d5 10.Nc3 (10.Qf3+ Kg6 11.Nc3 Rf8 12.Qd3 Bf5 13.Nxd5 c6 14.Nf4+ Kf7 15.Qc4+ Ke8 16.Be3 g5 17.Nh5 Bg6 18.Qe6+ Qe7 19.Ng7+ Kd8 20.Rd1+ Black resigned, Wall,B - Szachowski, playok.com, 2017) 10...Nxc3 11.Qf3+ Ke8 12.Qxc3 Be6 13.Be3 c6 14.Rd1 Rf8 15.h3 Qh4 16.Rd4 Qg3 17.Rd3 Qg6 18.Kh2 Kd7 19.Qb4 b5 20.Qd6+ Black resigned, Wall,B - MyDrunkAccount, lichess.org, 2016) 10.Qd5+ Ke8 11.Qxe4 Qe7 (11...Rf7 12.Nc3 d6 13.exd6+ Kf8 14.Qxh7 Qxd6 15.Qh8+ Ke7 16.Bg5+ Kd7 17.Rd1 Black resigned, Wall,B - Guest902091, PlayChess.com, 2017) 12.Nc3 Black resigned,Wall,B - Guest7889049, PlayChess.com, 2018.

9...Qh4+

This is an interesting and consistent idea - not found elsewhere in The Database - but it doesn't work. The pedestrian 9...d5 was more likely to be of help.

10.g3 Nxg3 11.Qd5+ 

This is why Black's idea doesn't work, as White protects his Rook. 

11...Ke7 12.hxg3 Qxg3+ 13.Ke2 Rf8 14.Be3 d6


The typical Jerome Gambit roles have been reversed: White has the extra piece, Black has two extra pawns.

15.exd6+ cxd6 16.Nc3 Rf5 



Some things in the Jerome Gambit don't change, however. Once again, Black's Bishop is at home, blocking a Rook. White's active pieces are ready to make the difference.

17.Rag1 Qxg1 18.Rxg1 Rxd5 19.Nxd5+ Kf7 20.Rf1+ Ke6 21.Nc7+ Black resigned



After the upcoming Nxa8, even if Black recovers the cornered Knight (not likely, as the Bishop will help it escape) he will remain down a Rook.

Cliff Hardy Jerome Gambit Adventure Number Three

Here is a third Cliff Hardy Jerome Gambit game, again a 10 minute game -  and again, playing blindfold!

Notes are by Cliff. I have added diagrams and an occasional comment in blue.

Hardy, Cliff - ronin7887
10 0, white playing blindfold
lichess.org, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 



Reaching this position for the third time in three games. There are 91 games in The Database with this position, going back to Vazquez - Carrington, 2nd match, Mexico, 1876. - Rick

10.f4 Qe7 11.Nc3 Kf7 12.O-O c6?!



+/=  Stockfish doesn't like this move and gives12...Re8 with a clear advantage for black. 

13.f5 Ne5 14.d4 Nc4?!



+/=  This move is quite clumsy for black and the odd move 14...Ned7 would have actually much better, with an equal position 

15.Qd3 Nb6 16.Bg5 h6? 



+- An unnecessary weakening of the black king; 16...Re8 would have been more circumspect, with a clear advantage for white 

17.Bh4 Re8 18.Rae1 Qc7? 

18...Nbd7 may have held out longer, though white would still have had an overwhelming initiative 

19.e5?! Nfd5?

Better would have been 19...dxe5 since after my planned 20.dxe5 Rxe5 21.Bg3 black would then have had the complicated 21...Bxf5! though then after 22.Qf3 his rook would still then have been lost on e5, so white would still have had a winning position in that circumstance anyway 

20.Ne4 dxe5 21.dxe5 Rxe5 22.Bg3 Kg8 23.f6 g5?



Weakening the king's position, though black is lost in any case 

24.Nxg5 hxg5??

The complicated 24...Bf5! was best, though white would still have been completely winning e.g. 25.Bxe5 Bxd3 26.f7+! Qxf7 27.Rxf7 hxg5 28.Rg7+ Kf8 29.cxd3 

25.Qg6+ Kf8 26.Bxe5 Qf7 27.Bd6+ Black resigned



Nice. Checkmate will arrive in 4 moves. Readers will notice Black's light-squared bishop at home, blocking the rook - a telltale sign that all is not well with black's position; and clearly punished by Cliff in this game. - Rick

Another Cliff Hardy / Jerome Gambit Adventure


Here we have another "Cliff Hardy" adventure, taking place a mere 3 hours after the previous one, against the same opponent.

Again, Cliff plays the Jerome Gambit in a 10 minute game -  playing blindfold!

Like any private eye story, first our hero gets into a whole lot of trouble. How he gets out is part of the adventure.

Notes are by Cliff. I have added diagrams and an occasional comment in blue.

Hardy, Cliff - Pomo12
10 0, white playing blindfold
lichess.org, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 



10.O-O Qe7 

Black varies from his plan in their previous game, which had seen 10...Ng4 and an eventual exchange of Queens. - Rick

11.Nc3 c6?!

The position is approximately equal. After 11...Kf7 black would have had a slight advantage. 

12.d4?!  

=/+ ; 12.f4was more accurate. 

12...Ng4?!  

+/= ; 12...Kf7 was better again 

"Amazing how popular this move is" was Cliff's comment in an earlier game. - Rick

13.Qg3?!  

= ; 13.Qd3! +/= would have been better 

13...Nf6 14.Bg5 h6?!

+/= ; 14...Kg8 = would have been less weakening 

15.Bxf6?! 

= ; 15.Bd2! Nxe4 16.Qxg6 Nxd2 17.Rfe1  +- when white's initiative is well worth the sacificed material 

15...Qxf6 16.Kh1?

The point of this lame move was that I intended to play 17.f4 without allowing 17...Qxd4+ but 17.Rad1, defending the d-pawn, would have made more sense, with black then having only a slight advantage.

Cliff continues to be hard on himself. Remember: he was playing this 10-minute game blindfold. - Rick 

16...h5? 

= ; 16...Nf4 stopping white from playing f4, with a winning advantage for black, would have been better. 

17.f4 h4 18.Qd3

With the obvious threat of 18...Nxf4?? 19.Rxf4 Qxf4 20.Rf1 with then a winning advantage for white 

18...Kg8 19.Rae1?

This ruined my position. I didn't notice that 18...Kg8 now meant that the f-pawn was under attack. 19.f5 would have been better, with an equal and interesting position. 

19...Nxf4 20.Qf3?

20.Qd2 =+  at least would have forced black to weaken his kingside with 20...g5.

20...g5?!

Inaccuracy. Best move was ...Nh5, but black still had a crushing position with the move played in the game 

21.e5 dxe5 22.dxe5 Qf5 23.g3 hxg3 24.Qxg3 Be6 25.Re4 Rh4 



-+

26.Qxh4

In a totally lost position, I attempted to seize the initiative and take advantage of black's exposed king

26...gxh4 27.Rexf4 Qh3??



After white's following move, black's queen was
trapped! Better would have been 27...Qh5 with a winning advantage for black

28.R4f3


+/= 

28...Qxf3+ 29.Rxf3 Rf8 



30.Kg2 Rd8 31.Rd3 Rf8 32.Rd6 Bc4 



32...Kf7

33.b3 Bf1+ 34.Kg1 h3?



Black's pieces now get tied up in a knot. 34...Bh3! 35.Rd1 should come out to a draw with accurate play. 

35.Ne4 Bg2 36.Nf6+ Kg7 37.Kf2 Rh8 38.Kg3 Rh6 39.Kg4 Rg6+ 40.Kf5 Kh6?! 

41.Rd7

Still winning but 41.Ng4+ Kh5 42.Rxg6 was even better 

41...Rg5+ 42.Kf4 Kg6 43.Ng4? Rf5+ 44.Kg3 Rg5 45.Rd6+ 



and black lost on time, admittedly in a lost position.

Black is helpless against a general advance of White's pawn and pieces, e.g. 45...Kf7 46.Kf4 Rg6 47.Nh6+ Kg7 48.Nf5+ Kf7 49.Rd7+ Kf8 50.Rxb7 Bd5 51.c4 Be6 52.Nd4 Rg4+ 53.Ke3 Rg6 54.Nxc6 etc. - Rick
