Whatever You Do, Don't Take Me Seriously

Here we have a short Jerome Gambit game whose brevity can be attributed to the defender relying on his sharp 7th move to win the game - when there was still plenty of play left in the position. Black's King went wandering, instead of staying home.

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

Transposing from the Bishop's Opening to the Italian Four Knights Game to the Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 d5

There are many ways for White to return some of the sacrificed material. This is one of the sharpest.

8.dxe5 Ne8

Or 8...Ng4 as in perrypawnpusher - NimbusReign, blitz, FICS, 2010 (0-1, 26); or 8...Bxf2+ as in perrypawnpusher - Marcym, blitz, FICS, 2010 (1-0, 20)

Possibly best is 8... Nxe4. 

9. Qf3+ Ke6 

After the safer 9...Kg8 and then 10.exd5 White would have three pawns for the piece, and the game would probably be even. 

10.O-O

This is good, but even better is 10.Qf5+ Ke7 11.Nxd5+ Qxd5 12.Bg5+!? winning a lot of material. 

10... Bd7 

Or 10...Kd7 11.e6+ Kd6 and Black will not last long. 

11.Qf5+ Ke7 12.Nxd5 checkmate
