Jerome Gambit: Checkmate, Of Course

The following bullet game is delightfully misleading. Black appears to be taking advantage of the open h-file, putting together a checkmating attack along it. Then, White goes and checkmates him.

Yes, the Jerome Gambit and bullet chess are like that.

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 

So far, so routine.

10.O-O Kf7 11.f4 Ng4 

Always the temptation to harass the Queen.

12.Qg3 h5 

Even moreso.

13.h3 Be6 

A daring offer of a piece, but he has an extra one. Or, is he offering two pieces? That can be risky, even in bullet.

14.f5 Bd7 15.fxg6+ Kxg6 16.hxg4 hxg4 



17.Nc3 Qe7 18.d4 Rh7 19.e5 Rah8 



And now there is a forced checkmate - but White delivers it.

20.Qd3+ Kh5 21.g3 g5 22.Kg2 Rf8 23.Rh1 checkmate



Wonderful!

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.

So far, so normal.

10.O-O Bg4 11.h3 Be6 12. f4 Qd7 13. f5 Bc4 14. d3 Nd


Before the "Jerome pawns" fall upon Black.

15.exd5+ Kd8 16.dxc4 Re8 17.Qg5+ Kc8 18.fxg6 hxg6 


After.

19.Nc3 b6 20.Bd2 Kb7 21.Rae1 Re5 22.Rxe5 dxe5 23.Qxe5 Rh8 24.Bf4 Rh5 

25.Qxc7+ 

Beginning a few quick moves to return some material and take the danger (for White) out of the picture.

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.

30.Ne2+ Ke4 31.c3 Rxh3 

Likely time-frantic.

32.Rxh3 Ke5 33.Re3+ Kd6 34.Re6+ Kc5 35.Nf4 g5 36.Nd3 checkmate
Nice.

Jerome Gambit: A Complex, Violent Affair

Image result for free clip art bullet


The latest Jerome Gambit game from Angel Camiña 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.
