Jerome Gambit: Attack Quickly


Everything happens quickly in a bullet game, especially an attack.

In the following game, angelcamina - who specializes in 1 0 bullet games with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) shows how it is done.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke8 

Declining the second piece has been examined in "Jerome Gambit for Dummies 2.0 (Part 4)" and "The Jerome Gambit Does That To You" (and elsewhere)

I was amused - but not surprised - that the lichess.org computer labelled this move a blunder.

If you have no idea what kind of devastating attack your opponent has just unleashed upon you, it is quite normal to decide not to choke on sacrificed pieces, but to put your King closer to safety. 

Verdict: psychologically sound, chessically suspect.

Why suspect?

While The Database shows little difference between retreating the King to e8 (421 games, White scores 54%) and retreating the King to f8 (614 games, White scores 56%); Stockfish 15 (at 34 ply) shows a definite preference for 5...Kf8, rating it as about 2 pawns better for Black, while rating 5...Ke8 as about a half pawn better for White

6.Qh5+ 

As mentioned in "Jerome Gambit: Over Quickly" and still true today

White takes advantage of the fact that Black's King has moved back to e8 - an aggresive check pushes forward his attack.

The computers recommend 6.Nxc6, which would be met by 6...Qh4!?, a counter-attack that remains unplayed.

6...g6  

Or 6...Ke7 7.Qf7+ Kd6 8.Nc4 checkmate, as in angelcamina - SammmDBest, lichess.org, 2021. 

7.Nxg6 

7...hxg6 

Natural, and likely the first thing to come to mind in a bullet game.

Still, it it interesting to point out that the computer recommends 7...Bxf2+, although the Database shows White scores 16 - 7 - 1 (69%) against the move.

8.Qxh8 

White has a Rook and 3 pawns for two pieces, but, more importantly, he has strong play against the enemy King.

8...Kf7

9.Qh7+ Kf6 10.c3 

Okay, this move isn't "faster than a speeding bullet", but it is powerful, nonetheless.

10...d5 11.d4 Bd6 


With a plan to return some of the sacrificed material and stifle the attack - although it has a slight flaw.

12.e5+ Bxe5 13.dxe5+ Nxe5 14.Qh4+ g5 15.Qxg5+ Black resigned


X-ray attack on the unprotected Queen.
