Jerome Gambit: Sidestepping the Sidestep



Black has a number of ways to sidestep the Jerome Gambit, even if he still wants to play 1...e5 and respond to 2.Nf3 with 2...Nc6.

Even in those lines, however, he has to be careful.


IDLEH2017 - Frusciante21

5 0 blitz, lichess.org, 2024

1.e4 e5 2.Bc4 Nc6 3.Nf3 Na5 

Black would like to win the "minor exchange," expecting to see 4.Bb3 Nxb3

White could charge him a pawn for the effort - 4.Nxe5 Nxc4 5.Nxc4 - but  he prefers to Jerome-ize the game.

4.Bxf7+ 

The earliest example I have of this in The Database is Sidran - Vong, Compuserve email, 1992 (1-0, 8), but there must be earlier ones outside of my research.

4...Kxf7 5.Nxe5+ Kf6 


Looking for trouble, although it might be hard to see that the best move for Black is 5...Ke7, with only a slight disadvantage. 

This is Black's only game in The Database. White has almost 600.

6.d4 

Solid. White usually goes for this move, or the more aggressive 6.Qh5 right away: 6...g6 (not 6...d6 7.Qf7+ Kxe5 8.d4+ Kxe4 9.Nc3+ Kxd4 10.Qd5#) 7.Qf3+ Ke7 (greed is a bad idea: 7...Kxe5 8.d4+ Kxd4 9.Qd3+ Ke5 10.Qd5+ Kf6 11.Bg5+) 8.Nc3 c6 9.d3 Bh6 (preventing the skewer of his King and Queen) 10.Nf7 Qf8 11.Nxh6 Qxf3 12.gxf3 Nxh6 13.Bxh6 and White ahead by two pawns.

6...d6 

Really, it was time for His Majesty to retreat to e7.

7.Qh5 

Or 7.Qf3+ Bf5 8.Qxf5+ Ke7 9.Qf7# 

7...Be7 

Too much to consider. Capture the Knight at e5? Kick the Queen with ...g6? Block the dangerous skewer d8-h4 diagonal?

8.Qf7 checkmate
