And Then

Following the two previous posts (see "The Jerome Gambit: Helping or Hurting?" and "Furthermore"), where I had consulted The Database to see how much help or hindrance the Jerome Gambit proper (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and the Italian Four Knights Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+), were on the actual (versus expected) outcomes of my games, I decided to see the effect of the Semi-Italian Four Knights Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Nf6 5.Nc3 Bc5 6.Bxf7+).

I found 51 games.

As expected in situations where I was offering "Jerome Gambit odds," the average rating of my opponents was about 42 points below mine, meaning that my expected score in the games was about 56%.

I actually scored 78%.

The Semi-Italian Four Knights Jerome Gambit seemed to be a help to my game.
