I certainly wish that I could find a definite link between Alonzo Wheeler Jerome, the "inventor" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), and the similar line in the Bishop's Opening (1.e4 e5 2.Bc4 Bc5 3.Bxf7+) - other than the references Gerald Abrahams made in two of his books, hence my naming the line the Abrahams Jerome Gambit.

Still, it's hard to overlook the following game, where White tops a player rated over 350 points above him. "outwitted"? I don't think so!  (When he looks over his game, I hope my notes help.)

outwitted - perece

standard, FICS, 2015

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 

Currently there are 16,200 Abrahams Jerome Gambit games in The Database (with many more to add). White wins 51%. This compares with 11,645 standard Jerome Gambit games (not counting transpositions from the Four Knights or the Semi-Italian) where White scores 45%.

3...Kxf7 4.Qh5+ Ke6 5.Nf3

While going over this game I found an interesting glitch in Stockfish 6. It evaluates the alternative move 5.Qg4+ as "=" (0.00) and keeps that evaluation even after the move 5...Kf7 is played, saying that after 6.Qh5+ the evaluation will still be "0.00". However, when I play 6.Qh5+ immediately see that after 6...Kf8 Black is rated 1.5 (or so) pawns better!?

For other thoughts on the move see "Exploring".


This is not as strong a move as in many of the regular Jerome Gambit lines.


Opening a line to add his Bishop to the attack. Next time outwitted will be ready with 6.Qe8+ Qe7 7.Qxc8 winning a piece.


6...Nc6best for Black, is still better for White. 


Straight forward. However, 7.Nxd4+ is the right way to go after the Queen, i.e. 7...exd4 8.Qd5+ Ke7 9.Bg5. (This is the second time that outwitted appears in The Database with the white pieces, and he is still feeling his way around.)


Now Black is OK.

8.Qg4+ Kd6

A better defense was 8...Kf7 9.Nh4 (9.c3 Bb6 10.Nxe5+ Black resigned, bobx - ABoni, FICS, 2007) 9...Qe6 10.c3 h6 11.Qxe6+ dxe6 12.Bd2 Bb6 13.O-O Nf6 14.Be3 Rf8 15.Bxb6 axb6 16.f4 exf4 17.Rxf4 g5 18.Rf1 gxh4 19.e5 Kg6 20.exf6 Rxf6 21.Rxf6+ Kxf6 22.Nd2 Ra4 23.Rf1+ Kg7 24.a3 Nc6 25.Nf3 h3 26.g3 e5 27.Re1 Kf6 28.Nh4 Rxh4 29.gxh4 Bg4 30.Rf1+ Ke6 31.Rf8 h5 32.Re8+ Kd5 33.Rc8 Kd6 34.Rh8 e4 35.Rh6+ Kd5 36.Rh8 e3 37.Re8 e2 38.Kf2 Ne5 39.Rd8+ Ke4 40.Re8 Kf4 41.Rf8+ Ke4 42.Re8 Kd5 43.Rd8+ Kc4 44.Rd4+ Kb3 45.Re4 Nd3+ 46.Ke3 e1=Q+ 47.Kxd3 Bf5 48.c4 Qxe4+ 49.Kd2 Qd3+ 50.Ke1 Kxb2 51.Kf2 Qe4 52.Kf1 Qf3+ 53.Ke1 Kc2 54.c5 Bd3 55.cxb6 Qe2 checkmate,  RattyMouse - vballmike, FICS, 2009


This works, in light of Black's response, but next time White might follow RattyMouse: 9.Nbd2 Nf6 10.Qg3 Nxe4 11.Nxe4+ Qxe4+ 12.Kd1 Bxb2 13.Rb1 Qd5+ 14.Ke2 Bc3 15.Rhd1 Bd4 16.Nxd4 Qc4+ 17.Ke3 Qc3+ 18.Rd3 Qc5 19.Rbb3 Nc6 20.Rbc3 Qxc3 21.Rxc3 Nxd4 22.Kd3 b6 23.Be3 Ba6+ 24.Kd2 Nc6 25.Qxg7 Rhg8 26.Qxh7 Rxg2 27.Qh6+ Ke7 28.Qh7+ Kd6 29.Qh6+ Ke7 30.Bg5+ Kf7 31.Qf6+ Ke8 32.Qh8+ Kf7 33.Qxa8 Rxf2+ 34.Ke3 Re2+ 35.Kf3 e4+ 36.Kf4 Black forfeited on time, RattyMouse - Udon, FICS, 2008

Stockfish 6's suggestion is 9.Nxd4 exd4 10.e5+ Kc6 11.O-O Qe6 12.Qf3+ Kb6 13.c3 Ne7 14.cxd4 c6 15.Nc3 Nd5


Lashing out. There is an idea behind the move, but White figures it out.

10.Kxf2 h6

The White Bishop is pinned.

11.Rd1+ Kc5 12.Rd5+ 

12. Be3+ is fine, too.

12...Kc4 13.Nxe5 checkmate.
