Jerome Gambit: It's Not Automatic

The following game has another example of an "automatic" pawn capture that would have benefitted from a bit more reflection before appearing on the board - but, playing at one minute a game, with no increment, there is a limit to the amount of reflection that is available.

White played Nc3 first, in angelcamina - JsFlexWay, 1 0 bullet, lichess.org, 2018 (1-0, 19).

10...Ng4

"Amazing how popular this move is" - Cliff Hardy.

11.Qf3+ Qf6

A bit stronger than 11...Nf6, as in angelcamina - Kvngmicky, 1 0 bullet, lichess.org, 2019, (1-0, 38).

12.Qg3 Kf7 13.h3 N4e5 14.f4 Nc6

15.e5

Excellent bullet psychology. This is not the strongest move in the position, but if Black automatically captures the pawn, he is busted.

15...dxe5 16.fxe5 Ngxe5 17.Rxf6+ gxf6

White has a Queen and a pawn for a Rook and Knight. More importantly, Black appears to be shaken.

18.d4 Nc4 

White finishes up after this, by placing his focus on the enemy King.

Jerome Gambit: Happy Birthday, Blog!

It is hard to believe, but 11 years ago, on June 10, 2008, I made my first post to this blog. You are welcome to check out "Welcome!" 

(You can read forward from the beginning to today's post, but, mind you, that would mean reading 2,780 posts!)

It has been exciting to see how many people are willing to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), and how many have been generous in sharing their games and their analysis. The play ranges from exceedingly fast 1 0 bullet games to more serious 3 days per move games, and include online, correspondence, blindfold, and over-the-board games.

It has also been great fun to see The Database of Jerome Gambit and Jerome-related games grow to over 59,000 examples.

As ever, I have enjoyed sharing many scintillating wins with the Jerome Gambit; but I have not shied away from showing losses and refutations, as I find them. The best place to learn how to win with the Jerome is this blog; the best place to learn how to defeat the Jerome is also this blog. 

Thank you, everyone, for your support. Thank you, Readers, for coming by.

Jerome Gambit: Cautious in Bullet?

I wonder if it pays to be cautious in bullet chess. Fending off attacks with your clock ticking down can not be much fun. It's probably more enjoyable to choose a wild opening like the Jerome Gambit, and just hack away.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6   

The Semi-Italian Opening, according to past world champion Euwe. It is also called the Anti-Fried Liver Defense, I suppose because it keeps a White Knight out of g5, where it plans to sacrifice itself on f7. If Black was planning with 3...h6 to protect f7 in this game, he was sorely disappointed.

4.Nc3 Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit. Compare with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 h6. The pawn move may create more weakness than it is worth.

 5... Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6

When you have a couple of pieces for a couple of pawns, and Stockfish 10 rates you as only +1 pawn, you have to know that your opponent has some serious dynamic potential. That is Black's situation at this point.

8.f4 Nc4 

Hoping to save one of the two hanging pieces, but actually surrendering both. The phlegmatic 8...d6 was the move. 

9. Qf5+ Ke7 10.Qxc5+ Nd6 11.e5 

11... b6 12.exd6+ cxd6 13.Qe3+ Kf7 14.O-O Nf6

White is better (material, development, pawn structure, King safety).

15.d3 Re8 16.Qf3 Kg8

Oversight. A 1 minute, no increment time control is brutal. 

17.Qxa8 Ba6 18.Qxd8 Rxd8 19.Bd2 Bb7 20.Rae1 Ng4 21.h3 Nf6 22.Ne4 Nd5 

23.Bc3 Ne7 24.Nxd6 Bc6 25.Rxe7 Rf8 

26.Rxg7+ Kh8 27.Rxd7+ Kg8 28.Rg7+ Kh8 29.Nf7+ Rxf7 30.Rxf7+ Black resigned

Jerome Gambit: Double Check It

When assembling a defense to a sketchy attack like the Jerome Gambit, it is always best to double check your work. Black does not do so in the following game - with a time control of 1 minute, no increment, there is not much time for reflection - and immediately pays the price. Later on, the game is decided, ironically, by a double check.

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

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bb4

Black is not just saving his Bishop, he is pinning the enemy Knight that protects the e4 pawn. In doing so, he overlooks that the pawn is also indirectly defended. Better was the direct 7...Bd6 8.dxe5 Bxe5.

8.dxe5 Nxe4 9.Qd5+ 

The point.

9...Ke8 10.Qxe4 a5 

It is unclear what Black has in mind. Perhaps it is a do something, quickly move in bullet.

11.O-O g5 

This falls to a tactical onslaught.

12.Nd5 Bc5 13.Nf6+ Ke7 14.Bxg5 h6 15.Nd5+ Black resigned

Black will lose his Queen, and then be checkmated.
