I have updated The Database with games from FICS (Free Internet Chess Server) through 2014. It now contains over 39,000 games.

The basic Jerome Gambit position, after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, appears in about 11,600 games. White scores 45%

The Italian Four Knights Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+, appears  2,300 times. White scores 38%.

Interestingly, the Semi-Italian Four Knights Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.0-0 Bc5 6.Bxf7+, appears only 120 times, but White scores 65%. Note the "power" (or lack of) ...h6.

This is reflected in the Semi-Italian Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Bc5 5.Bxf7+, appearing in about 160 games, where White scores  66%. Interestingly, with 4.Nc3, in about 130 games, White scores only 54%.

The Blackburne Shilling Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+, appears in about 5,000 games, with White scoring 56%.

Recent examples of the Abrahams Jerome Gambit, 1.e4 e5 2.Bc4 Bc5 3.Bxf7+, have been added. There are a little over 2,500 examples, and White scores 50%.

Because the line continues to show up, and is worth knowing, the nameless 1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 4.Bxf7+  appears in The Database 2150 times, with White scoring  72%.

There is also a large selection of Jerome-ish lines, featuring, for example, an early Bxf7+ by White. Some Reversed Jerome Gambit games have been included, as well.
