Jerome Gambit: Sometimes the Wheels Come Off

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.

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 normal.

10.O-O Bg4 11.h3 Be6 12. f4 Qd7 13. f5 Bc4 14. d3 Nd5 

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

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.

Jerome Gambit: More Bullets

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

Quickly.

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 Camiña...

angelcamina - zorosyria00 
1 0 bullet, lichess.org, 2019 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 Nc6 

9.Qc4+ d5 10.exd5 Nxd5 

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.

15.Be3 Rf8 16.O-O-O+ Ke7 17.Bc5+ Ke8 18.Qxf8 checkmate

Jerome Gambit: The Pawns, Again

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 Camiña, 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.

Jerome Gambit: My Opponent Knows What He Is Doing (Part 4)

[continued from previous post]

perrypawnpusher - warwar
"Italian Battleground", Chess.com, 2019

At this point in the game, I was still thinking about moving my King to the center to help advance the pawns, although I couldn't figure out exactly how. In the mean time, my Rook on f8 was designed to keep Black's King away from interfering in the center.

Here, my opponent took several days "vacation" from the site, and I worked on my portable chess set like it was a crystal ball (the time control was 3 days per move). For starters - what was the reasoning behind my opponent's last move? (In hindsight, I can see that he missed a decent drawing line - by returning material - but what was he trying to do with his Bishop on c3?)

38...Bd7

It turns out that my Rook pins down its opposite, and forces Black's light square Bishop to stay on the a4-e8 diagonal, for protection. With that paralysis of pieces, it was possible to see that Black's other Bishop was now going to be stuck on the wrong side of the pawn chain. (It had arrived on the a5-e1 diagonal to forestall b3-b4.)

39.Bc5 

The key. Now my Bishop can escort the pawn through b4, on the way to promotion. My King can stay at home and mark his counterpart, after all.

39.Bc5

The Bishop can reach out and help.

39...Bc6 40.b4 h5 41.b5 Bd7 42.b6 Black resigned

Once again, saved by the "Jerome pawns", but only after some difficult play.

Hats off to warwar for a challenging game.
