Jerome Gambit: The Human Move (Part 3)

 

                                    [continued from the previous post]

Looking further as to how the computer program maia fared in defending against the Jerome Gambit 

It scored 21 - 43 - 8 (35%) using the Blackburne defense 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6. Apparently it was not not able to overcome the loss of the Rook after 8.Qxh8 (a complicated variation, ultimately evaluated as even), overall underperforming its rating by 130 points;

It scored 19 - 18 - 2 (51%) using the 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 defense, outperforming its rating by 50 points

We will look at some representative games in these main Jerome Gambit lines, but first will turn to the fact that maia faced 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 6.d4 once and 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 6.0-0 once.

That was quick.

Stockfish 15.1 rates Black as about 3 1/2 pawns better. 

The Database shows White scoring 2 - 10 from this position.

White hung his Queen in an already worse position.
