Jerome Gambit: A Certain Amount of Bravery

 Playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) requires a certain amount of bravery. White sacrifices a couple of pieces for an attack, and this may lead to an overwhelming game - or a difficult loss. In the meantime, Black can defend quietly and stubbornly, or wildly - or he can offer to return some of the sacrificed material, after he has poisoned it.  

The following game is a good example of White going into complications that best requires previous study. However, the time control for the game is 1 minute, no increment, and in such an environment players can take risks knowing that attempts at refutation will cost the opponent too much time, or a shortage of time will keep the opponent from analyzing deeply. It's a risky strategy, but so is playing the Jerome Gambit.

And, what if Black knows the proper defense and counter attack? Well, then, it is best that he remember it accurately, or it will all be for naught...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 

Usually the start of either Blackburne's Defense or Whistler's Defense.

7.Qxe5 d6 

Blackburne's, it is. (Whistler  played 7...Qe7.)

8.Qxh8 Qh4

 This was Henry Joseph Blackburne's idea, and he eventually produced the most well known Jerome Gambit game, Amateur - Blackburne, London, 1884, a crushing, sacrificial win for Black. Further play and analysis, however, showed that White had at least a draw, if not an advantage, amidst the complications. (The Database, for example, has 277 game examples, with White scoring 55%.)

Recent games have shown Black varying from Blackburne's plan, to their misfortune

9.O-O 

As I have posted, before, about a main alternative 

Munoz and Munoz, in their notes to Amateur - Blackburne, London, 1885, in the Brooklyn Chess Chronicle, suggested "He should have attempted to free his pieces by P to Q4 [9.d4] before castling." 

The move 9.d4 received a good look in "Updating the Jerome Gambit (Part 1)", including references to L. Elliot Fletcher’s energetic Gambit’s Accepted (1954), an internet article on Amateur - Blackburne (at www.superajedrez.com) by Brazil's Hindemburg Melao, and some musings and analysis from Bruce Pandolfini, in his 1989 Chess Openings: Traps & Zaps !

9...Nf6 10.Nc3 

The Knight looks like it is heading to d5, to hit the enemy Knight and secure the release of his Queen.

Here, though, it is useful to know the recommended 10.Qd8 Bb6 11.e5 dxe5 12.Qd3, and Her Majesty has escaped, with a slight advantage.

10...Ng4

The proper way to bring the  pain.

11.h3 

Now, how did that Blackburne game go? Did he capture with the Bishop or the Knight?

11...Nxf2 

Bummer. After 11...Bxf2+ 12.Kh1 Bf5, instead, White would lose his Queen.

Talk about complications. White now has the rescue move 12.e5, when 12...dxe5 13.Qxe5 would not only free his Queen, it would allow White to force a draw by repetition, checking the enemy King - unless Black answered with 13...Bf5, when Black would be able to split the point after 14.Qxc5 Nxh3+! and he can repeat the position with checks. Of course, after 12.e5 Bf5 13.Qf6+ Qxf6 14.exf6 would lead to an even game, although Stockfish 11 suggests that White may have an edge, unless Black tries 14...Nxh3+ 15.Kh2 Nf2+...

But, wait! White has another, better move.

12.d4 

Ah, yes. (See the note to White's 9th move.)

What exactly can Black do, now?

For starters, he has the delightful 12...Bf5, which puts a third and fourth piece en prise, and almost works, except for 13.Rxf2, when it turns out that White can afford to give up his Queen: 13...Rxh8 14.dxc5 and White will gather in the Bishop at f5, as well, giving him a Rook and two pieces for the enemy Queen.

Instead, 12...Bxh3 looks equally Blackburnian, but 13.Bg5! is a complete answer.

The fortunes of the players has reversed, and White is now clearly better. 

12...Bxd4 

This allows the escape of White' Queen and the end of Black's tactical surprises. 

13.Qxd4 Kg8 14.Qxf2 Qe7 

Black is down a Rook and a Knight - and, soon, a King.

15.Bg5 Qe8 16.Bh6 Be6 17.Qf6 Bf7 18.Qg7 checkmate

That is quite a lot of Jerome Gambit, for 1 minute of play on each side. And, as they say, Fortune favors the bold.
