Finish Him Off!
There are about 165 games by jfhumphrey in The Database, many, like the next game, with White playing against a higher rated player.
Defending against the Jerome Gambit means 1)finding a refutation, 2)following it with accurate play, and then 3)finishing off the attacker.
The longer that Black delays that third step, the more likely it is that he will suffer a calamity himself.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+
The Italian Four Knights Jerome Gambit.
5...Kxf7 6.Nxe5+ Kf8 7.Nxc6 bxc6
Even though Black would have done better with 6...Nxe5 and 7...dxc6, he still has a playable game, with an edge.
8.0-0 Ba6 9.d3 d6 10.Ne2 h5
It is hard to tell if this is aggression or disrespect. In either event, Black should not play around, but finish off his opponent.
11.Nf4 Qe8 12.c4 Bc8 13.Be3 Bb6 14.Bxb6 cxb6
White is showing the calm patience that often is strangely rewarded in the Jerome. In this case, Black becomes careless.
15.Qf3 Qe5
Ouch.
16.Ng6+ Kg8 17.Nxe5 dxe5 Black resigned
Moral: when you have the advantage, do not play around, but finish your opponent off!

Long Distance Traveller
Readers, it is time to get out your chessboards and play along, as Philidor1792 (who shows a lot of patience in an impulsive opening) explores Whistler's Defense, the improvement on Blackburne's Defense that was so devastating that Alonzo Wheeler Jerome seems to have "forgotten" to mention it in his writings.

Sailing Off Again
Bouyed by his recent draw against the computer in the difficult "Nibs" variation of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) (see "Sailing Off of the Edge of the World") Philidor1792 played three more exploratory games with Crafty, two with the White pieces and one with the Black.
This time the results were not as encouraging.
Philidor1792 - Computer (Crafty)

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
7.Qf5+ Kd6 8.f4 Qh4+ 9.g3 Nf3+ 10.Kd1 Ne7
Despite Philidor1792's previous escape, White (not Black) is in big trouble here.
11.e5+ Kc6 12.Qe4+ d5 13.exd6+ Nd5 14.gxh4 Bg4 15.Qa4+
One of the new games continued, instead, in a novel direction with 15.d4 Rae8 16.Qxe8+ Rxe8 17.h3 Bh5 18.dxc5 Ne1+ 19.Kd2 Re2+ 20.Kd1 Re3+ 21.Kd2 Nf3+ 22.Kd1 Ne5+ 23.Kd2 Nc4 checkmate, Philidor1792 - Computer (Crafty);
Another, with the computer taking the White pieces, introduced another new line 15.f5 Nxh2+ 16.Ke1 Rae8 17.d3 Bxf5 18.Rxh2 Bxe4 19.dxe4 Rxe4+ 20.Kd1 Bxd6 21.Rh1 Rd4+ 22.Bd2 Rf8 23.c3 Rg4 24.Kc2 Rf2 25.Kb3 Rgg2 26.Rd1 Rh2 27.a4 Bf4 28.c4 Nf6 29.Bc3 Rxh4 30.Na3 Rhh2 31.Nb5 Be3 32.Rd3 Bc5 33.Nd4+ Kb6 (33...Bxd4 would have preserved Black's advantage) 34.a5+ Ka6 35.Ne6 b6 36.axb6+ Kxb6 37.Nxc5 Kxc5 38.Ra6 Rf4 39.Bb4 checkmate, Computer (Crafty) - Philidor1792.

Crafty significantly improves over its previous 16...Nb6, Philidor1792 - Computer (Crafty) (½-½, 89).
17.h3 Bh5 18.c3 Rhe8 19.Kc2 Nd4+ 20.cxd4 Nb4+ 21.Kb3 Nxa6
Black's extra piece will outplay White's extra pawns.

Moral: Be careful to which computer (and when) you give Jerome Gambit odds.

One Man's Treasure...
"One man's treasure is another man's trash."
Following up on yesterday's post "Ionman vs the Bots" I messaged ionman, asking about the games. Given their theoretical nature, I thought that I might have discovered a new member of the Jerome Gambit Gemeinde who had a whole powerhouse of new ideas to pushe the understanding of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) forward.
Not so.
"I was just messing around in those games" he responded.

Ionman vs the Bots
The early Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games by ionman at FICS seem to have all been played against computer bots, providing not only a bit of a historical perspective but also some interesting analytical off-shoots. They are well worth playing through.
I have messaged ionman at FICS, and hope to learn more about his explorations.

As we have seen in "Sailing off the Edge of the World", ionman also faced 6...Ke6: 7.Qf5+ Kd6 8.f4 Qh4+ The choice of the mscp bot.
Instead, 8...Bd4 was the choice of the Fleurybot and FleurybotJr bots 9.c3 (After the stronger 9.fxe5+ Black has to find 9...Kc6 which is the only move that keeps his edge 10.c3 d5 11.Qf4 Bb6 12.exd5+ Qxd5) 9...Nd3+ 10.Ke2 Ne7 (10...Nh6 11.Qd5+ Ke7 12.Qxd4 Nxc1+ 13.Rxc1 Qf8 14.Qe5+ Kd8 15.f5 Ng4 16.Qg3 h5 17.c4 d6 18.d4 Bd7 19.Nc3 Bc6 20.d5 Bd7 21.Rf1 Rh6 22.h3 Ne5 23.Rf2 Nxc4 24.Raf1 Nxb2 25.e5 Nc4 26.Ne4 Nxe5 27.f6 Bb5+ 28.Ke3 Bxf1 29.Rxf1 gxf6 30.Qh4 Kc8 31.Rxf6 Qe7 32.Qg5 Rh7 33.Qg8+ Kd7 34.Qg6 Nxg6 35.Rxd6+ cxd6 36.Kd4 Qe5+ 37.Kc4 Qxe4+ 38.Kb5 Qxd5+ 39.Kb4 Qxa2 40.g4 Qb1+ 41.Kc4 Ne5+ 42.Kd4 Qd3 checkmate, ionman - FleurybotJr, blitz, FICS, 2005) 11.e5+ Nxe5 12.fxe5+ Bxe5 13.Qd3+ Kc6 14.Qe4+ Kd6 15.d4 Bxh2 16.c4 c6 17.c5+ Kc7 18.Rxh2 d6 19.cxd6+ Qxd6 20.Bf4 Nf5 21.Bxd6+ Nxd6 22.Qe5 Re8 23.Qxe8 Bg4+ 24.Kd3 Bf5+ 25.Kd2 Rxe8 26.Nc3 Nc4+ 27.Kd1 Nxb2+ 28.Kc1 Nd3+ 29.Kd2 Kb6 30.Rhh1 h6 31.Rhb1+ Kc7 32.a4 Re7 33.a5 Kd6 34.a6 b6 35.Ne2 Re8 36.Nc1 Nf4 37.Rb3 Re4 38.Re3 Rxd4+ 39.Ke1 Nxg2+ 40.Kf2 Nxe3 41.Kxe3 Re4+ 42.Kf3 g5 43.Ne2 g4+ 44.Kf2 Be6 45.Rd1+ Bd5 46.Nc3 Rf4+ 47.Ke1 g3 48.Ne2 g2 49.Ng1 Rf1+ 50.Kd2 Bc4 51.Kc1+ Ke5 52.Nf3+ Rxf3 53.Rg1 Rf1+ 54.Rxf1 gxf1Q+ 55.Kd2 Qd3+ 56.Kc1 Bd5 57.Kb2 Qd2+ 58.Ka3 Qc3+ 59.Ka4 Qb3 checkmate, ionman - Fleurybot, blitz, FICS 2005;

The "Kick Me Maneuver"
ionman - RavingEagle
blitz, FICS, 2011
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening. If Black subsequently brings his Bishop out to c5, White can consider going Jerome-ish with Bxf7+.
4.d4 Na5
At some point this offside Knight move is going to become known as the "kick me maneuver".
5.Bxf7+ Kxf7 6.Nxe5+ Ke8
It is a measure of Black's difficulties to realize that his "strongest" move here is 6...Ke7, allowing the Knight fork at g6.
7.Qh5+ Ke7 8.Qf7+ Kd6 9.Qd5+
This is strong and winning.
Checking out The Database, only sanforu - goaheadandtakemy, blitz, FICS, 2008 has 9.Na3 that leads to mate in 3; and only plasmafaz - Abatwa, blitz, FICS, 2012 has 9.Nc3 that leads to mate in 4.
No matter, White has the fork mentioned in the note to move 6.
9...Ke7 10.Ng6+ Ke8 11.Nxh8 Nf6 12.Qf7 checkmate

Lost in the Mists of the Past
In yesterday's post I mentioned a couple of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games played online by ionman at FICS in 2005 and suggested that I check out more of his games.
That led me to The Database, which has FICS games going back to 1999. I found ionman's games, but I also found a number of players doing more than single-game-experimenting with the Jerome, some of whom were familiar (e.g. GOH, JKELSEY ), but some of whom were new to me (when a database has 26,500+ games, it is possible to overlook someone).
I plan to see which players are still active at FICS, and contact them for more information about their Jerome Gambit adventures.
