One More Thought

Musing over the earlier post, "Unasked Questions", which concerned itself with a sort of an "impatient Jerome Gambit" - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 (the Two Knights Defense) 4.Bxf7+ (not waiting for Black to play ...Bc5) - I remembered a tangential question that I had asked about what impact further developing a Knight for each side - creating the Italian Four Knights Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ - would have, compared to the regular Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

It turned out that Komodo 10 evaluated the Four Knights version as improving Black's position 3/4 of a pawn over Black's position in the regular Jerome. Furthermore, The Database showed that Black scored 61% in the Four Knights variation, versus 54% in the regular Jerome Gambit line.

So, I had one more thought: Might that mean, analagously, that the line that we looked at in the earlier post would be stronger for Black than if we stripped away a Knight from each side, i.e. if we had Komodo 10 look at 1.e4 e5 2.Bc4 Nf6 3.Bxf7+ ? (Would I dare to call it a sort of "accelerated impatient Jerome Gambit"? I hope not.)

It turns out that Komodo 10, at 30 ply, sees only about 3/100th of a pawn's difference between 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ and 1.e4 e5 2.Bc4 Nf6 3.Bxf7+. Not much at all, as far as computer evaluation goes.

However, checking The Database, I noted 479 games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ and 443 games with 1.e4 e5 2.Bc4 Nf6 3.Bxf7+. In the first case, Black scored 61%; in the second case, 52%. From a practical point of view, that may be significant - even if you take into account that The Database is not as statistically representative for these two lines, because my data collection has not been as rigorous.

In both cases, it seems that Black's practical chances are improved as his development increases, even though White increases his development equally.

Curious.

Should White abandon the Jerome Gambit for 1.e4 e5 2.Bc4 Nf6 3.Bxf7+? No, I wouldn't go that far.

But I would refer Readers to "Jerome-Knight Gambit" for a collection of those accelerated, impatient games.
