Jerome Gambit: Faux Defense

In the Jerome Gambit, White sacrifices a couple of pieces. Most of Black's defenses are based upon returning a piece. Sometimes Black just develops a piece, saying, in effect "You choose the piece that you want back, I'm too busy with my other pieces."

The following game follows that defensive scenario, although Black's choice at move 7 gives back 2 pieces - leaving White up a couple of pawns. There are some interesting tactics following, but the defender's overwhelming advantage at move 4 has become a significant advantage for the attacker, three moves later.

Bullet chess - and the Jerome Gambit - is like that.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Nf6 



At first glance - if only a glance - this move looks fine. In bullet chess you don't always get more than a glance. Still, this is not an effective defense, and The Database points out that in 62 games, White scores 72% against it.

8.Qxe5+ Kf7 9.Qxc5 d6 10.Qe3



A bullet chess game is truly an event that took less time than it takes to tell...

The next time angelcamina plays this line, though, he might try 10.Qb5 here, instead, as against the move in the game, Black can grab back a pawn with 10...Nxe4, since the lined-up White Queen and King on the e-file do not allow the first player to recapture.

It is no big deal that White did not see that tactic, playing at that speed - Jerome Gambit regulars such as blackburne, MrJoker, and Petasluk, among others, playing much more slowly, missed it, too; and none of the defenders found 10...Nxe4!?, any way. (Hmm... This should be added to my series of "Jerome Gambit Secrets".)    

10...Qe7 11.d3 Re8 12.O-O Ng4 



When in doubt, or at a loss for an idea, harass the enemy Queen.

13.Qg3 Qd7 14.h3 Nf6 15.e5 



Standard Jerome Gambit attacking motif. Black gets to snap off a pawn (more solid, but less incisive, was 15.b3 followed by 16.Bb2), but that takes thinking time to figure out, and time is precious.

15...dxe5 16.fxe5 Qd4+ 17.Kh1 Rxe5 



My preference is to capture with the Queen, but perhaps Black wanted to keep the piece on the board and not allow it to be exchanged.

18.Nc3 Be6 19.Bf4 Rf5 20.Bxc7 Rxf1+ 21.Rxf1 Rc8 



22. Be5 Qe3 

An oversight that ends the game. Time pressure?

23.Qxe3 Black resigned

Even without the slip, Black was in a bad way, faceing a 2-pawn deficit and very uncomfortable pressure on his Knight (and the King behind it).

Jerome Gambit: Sometimes the Wheels Come Off

Image result for free clip art car no wheel



One of my biggest concerns about bullet chess (1 minute, no increment) is that I simply can't think that fast. I am afraid that my attention will wander, too, and suddenly my game will look like the faltering car, above.

In the following Jerome Gambit game, White is the recipient of a handful of Huh? moves by his opponent, and all that is left to do, then, is safely drive home the full point.

As I cheer on angelcamina, I am also sympathetic toward billylaw, as my fate could have been his.

25...Qxc7 26.Bxc7 Kxc7 27.Rf7+ Kd6 28.Rf3 Kc5 29.b3 Kd4 


The King wants to be active and make up for the missing piece.

Likely time-frantic.

Jerome Gambit: A Complex, Violent Affair

Image result for free clip art bullet


The latest Jerome Gambit game from Angel CamiƱa is a complex, violent affair - the kind of thing you
might expect if both players arrived at the board fully prepared for battle.

angelcamina - davidbrooklyn2
1 0 bullet, lichess.org, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 



The Jerome Defense to the Jerome Gambit, a practical response that seeks to keep Black's King out of danger, while it returns one of the two sacrificed pieces. One downside is that the King may have to move to let the Rook out, something that often turns into castling-by-hand. 

7.Qxe5 d6 8.Qc3 Qh4 

Black is not intimidated, he is ready for a fight.

9.O-O Nf6 10.d4 Bb6 11.e5 



Attack!, the watchword of both the Jerome and bullet chess.

It is interesting, and somewhat amusing, to see the computer's recommendation, where Black eventually returns the second piece, and things wind down to an endgame where the defender is up a pawn (plus a Bishop for a Knight): 11.f3 Kf7 12.a4 a5 13.Be3 Be6 14.Nd2 Rhc8 15.f4 Kg8 16.f5 Bd7 17.Qd3 Qh5 18.h3 Kh8 19.Rf3 g6 20.g4 Nxg4 21.hxg4 Qxg4+ 22.Kf2 gxf5 23.d5 Bxe3+ 24.Qxe3 Rg8 25.Qc3+ Rg7 26.Rg3 Qxg3+ 27.Qxg3 Rxg3 28.Kxg3 fxe4 29.Nxe4.

11...dxe5 12.dxe5 Ng4 13.h3 



13...Nxf2 

Brutal, but Black has overlooked the fact that there is one response that turns the game around. He should have tried the other capture, 13...Bxf2+, and, after 14.Kh1 Be6 15.Nd2 Kg8 16.Nf3 Qg3 17.hxg4 h5!? the attack continues, for example 18.g5 Rf8 19.Rxf2 Qxf2 20.Be3 Qg3 21.Rf1 h4.

14.Be3 

Does the trick.

14...Bxe3 15.Qxe3 Bxh3 

This move would be unplayable at any normal time control, but at bullet, it is a stroke of psychological genius - or grim dispair.

16.Rxf2+ Ke7 17.Qxh3 Qd4 

Black does not wish to exchange Queens - but, soon, he goes in for mass exchanges, perhaps influenced by the clock..

18.Nc3 Raf8 19.Raf1 Rxf2 20.Rxf2 Rf8 21.Qg3 Rxf2 22.Qxf2 Qxe5 23.Qe2 Qxe2 24.Nxe2 Kf6 25.Kf2 Black resigned



Whew! Likely Black was behind on the clock, and figured that resistance was, therefore, futile.

Jerome Gambit: More Bullets

Bullet chess: know your openings, watch out for tactics, punish your opponent's errors.

Quickly.

angelcamina - sugerlove
1 0 bullet, lichess.org, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



The Jerome Gambit, not the "quiet game".

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Ng6 



Black realizes he has to give back a piece, and "volunteers" the Bishop. The computers suggest that White take the offer, although the (limited) practical results of The Database back the next move in the game: 8.Qxc5 scored 3 - 2; 8.f5 scored 2 - 0.

In bullet chess, there has to be extra value in distressing the enemy King.

8.f5+ Ke7 9.fxg6 Nf6 

It is tempting to follow C.J.S. Purdy's advice to find a move that "smites", but it is always best to check your own situation, first. 

10.Qxc5+ d6 11.Qe3 Kf8 12.gxh7 Rxh7 13.O-O Kg8



Both sides have castled (one, by hand), and White has a 2 pawn edge.

14.d4 Bg4 15.Nc3 Qd7 16.Bd2 Re8


Taking time to build their positions.

17.Qg3 Nh5 18.Qf2 Nf6 19.Rae1 

White declines the offer to pursue a draw with 19.Qg3 Nh5, etc. He is almost immediately rewarded.

19...Qc6 20.e5 Nd5 21.Qf7+ Black resigns


After 21...Kh8 the Queen sac finishes: 22.Qf8+ Rxf8 23.Rxf8 checkmate.

Jerome Gambit: Faster Than A Speeding Bullet

If Alonzo Wheeler Jerome played bullet chess - one minute a game, no increment - his gambits would probably look something like the following game from Angel CamiƱa...

A slip - perhaps Black was counting on his next move to regain the piece. If so, at the speed he was playing, he didn't see that White could slip out of trouble.

11.Nxd5 Be6 12.Qf4+ Ke8 


13.Nxc7+ Kd7 14.Nxa8 Qxa8 


White is up the exchange and a couple of pawns, but he wants more.

Jerome Gambit: The Pawns, Again


Image result for free clip art pawns



In the Jerome Gambit, White may get "only" a couple of pawns in exchange for his sacrificed piece, but, if he gives his pawns a chance, they can prove very helpful in the outcome of the game. The following contest is an example.

White's calmness in the face of aggression at the end of the game is exciting, too - why become upset, if you can checkmate your opponent, first?

vlastous - ADELAZIZ
internet, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8


The Jerome Defense, presented by Alonzo Wheeler Jerome in his earliest published analyses.

7.Qxe5 d6 8.Qf4+ Qf6 

This is a perfectly logical move, offering to exchange Queens to blunt White's attack; and although it does not show up in early Jerome Gambit analyses, The Database points out that it is played twice as often as 8...Nf6.

9.d3 Qxf4 10.Bxf4 Nf6 

11.Nc3 Kf7

This looks like a slight improvement over 11... a6, which was seen in vlastous - Nyanyiwa, internet 2017, (1-0, 34) 

12.h4 Rf8 13.f3 Nh5 14.Bh2 Bb4 15.g4 Nf6 16.O-O Be6 



The "Jerome pawns" already take on a menacing look, but Black is still doing fine. His problem will be finding and executing a successful defense and counter-attack.

17.Bg3 a6 18.Ne2 Rad8 19.Nf4 Rfe8 20.c3 Bc5+ 21.d4 Bb6 22.Kg2 d5 

The move ...d5 is frequently good against the Jerome Gambit (and 1.e4 e5 openings in general) but here the move gives White's Kingside ambitions encouragement. Stockfish 10 suggests the quieter 22...g6.

23.e5 Ng8 24.Nxe6 Rxe6 25.f4 c5 



The right idea, hitting back at the growing center.

26.f5 Rc6 27.e6+ Ke8 28.Be5 cxd4 



This move looks like a slip, according to Stockfish 10, which suggests, instead, 28...Kf8 29.dxc5 Bxc5 30. g5 Bd6 31.Bd4 Bc5 and a draw by repetition.

The computer is not yet impressed by the "Jerome pawns", but the problem with the text move is that White does not have to recapture at d4 - he can take the g7 pawn, instead, opening the way for the connected passed pawns that have suddenly grown fierce.

29.Bxg7 dxc3 30.bxc3 d4 

To open lines, but his King's castle has already been breached.

31.g5 dxc3 32.f6 Rd2+ 33.Kh1 Rc4 



Black's counter-attack looks scary, but White has one move at his disposal that brings home the point - by implementing his own mating attack.

34.f7+ Ke7 35.f8=Q+ Kxe6 36.Rae1+ Kd7 37.Qe8+ Kc7 38.Be5+ Black resigned

Beautiful!

Jerome Gambit: Noticing A Tactic

Here we have another 1-minute bullet game from Angel CamiƱa, who notices a common tactic in the Jerome Gambit - 
the Queen check that also attacks an unprotected minor piece. Black could
have continued in the game, but he would have done so a pawn down.
