I have been looking at a Jerome Gambit-related opening line that does not appear to have a name. Although I have covered it a number of times on this blog - "Offside!" "The Other Side" "Bishop in A Hurry", "Watch that last step...", "It Worked -- This Time", "A Line of Play Everyone Should Know About", "The Psychology of Error in Chess", "It Takes More Than Just One Move", "Checking Back", "Huh?", "A Snack", "Betcha Can't Eat Just One", "Entertaining and Educational", "Barely Got His Coffee Sipped", "Crime and Punishment", "Hard to Believe", "Poison", "Puzzling", "A New Mate", "On the Other Hand", "Chess Marches On", "Chess Marches On (Again)", "Always Good To Remember", "Cure Worse Than the Disease", and "Repetition Helps Those Who Pay Attention" - I have only played it twice, and only faced Black's best response once.
I am talking about 1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5,
which certainly can be met with 4.Nxe5 with an edge for the first player, but which I like to meet with 4.Bxf7+.
After 4...Kxf7 5.Nxe5+ (there are 1933 games with this position in The Database, and White scores 72%) the strongest reply appears to be 5...Ke7 (although this move is seen only 371 times in The Database, that is less than 1/5 of the time, and White scores 70%).
How should White proceed?
As in "A Discussion Continued" I invited Stockfish 6, Houdini 3, Rybka 3 and The Database to consult with me. There were ideas and disagreements galore.
In my original notes to perrypawnpusher - wred, blitz, FICS, 2011, I pointed out that Rybka 3 preferred 6.Nc3. The move appeared 11 times in The Database. White scored 73%. The most recent game with the line continued 6...d6 7.Nd5+ Ke8 8.Qh5+ Black resigned, Alnischu - Kaliz, blitz, FICS, 2013.
On the other hand, 6.d4 was preferred by Stockfish 6. The move appeared 171 times in The Database. White scored 64%. The most recent game with the line continued 6...Nf6 7.Bg5 d6 8.Bxf6+ Kxf6 9.Ng4+ Kf7 10.Qf3+ Bf5 Black forfeited by disconnection, seinfeldaddict - JDZAAA, standard, FICS, 2014.
However, Houdini 3 preferred 6.Qf3. The move appeared in 27 games in The Database. White scored 70%. The most recent game with the line continued 6...Nh6 7.d3 Qe8 8.Bxh6 gxh6 9.0-0 Bg7 10.d4 d6 11.Nd3 Bxd4 12.c3 Bf6 13.Nd2 Rf8 14.Qe2 h5 15.Nf4 Bg4 16.Nd5+ Kd7 17.Nxf6+ Rxf6 18.f3 Be6 19.Rfe1 Rd8 20.c4 Kc8 21.b3 Qg8 22.Qf2 Nc6 23.Nf1 b6 24.Ng3 Ne5 25.Rad1 Ng4 26.Qd2 Ne5 27.Qd4 h4 28.Qf2 hxg3 29.Qxg3 Rg6 30.Qf2 Bh3 31.g3 Nxf3+ 32.Qxf3 Bg4 33.Qg2 Bxd1 34.Rxd1 Rf8 35.Qh3+ Kb8 36.Qd7 Rgf6 37.e5 Rf2 38.exd6 Rc8 39.dxc7+ Rxc7 40.Qd6 Rxa2 41.Rf1 Qe8 42.Rf8 Qxf8 43.Qxf8+ Rc8 44.Qf4+ Rc7 45.Qe5 Kb7 46.Qd5+ Kb8 47.b4 Re7 48.Qd8+ Black resigned, sadhamlet - whickmeister, blitz, FICS, 2014.
What did I actually play in my game against wred? Why, 6.Qh5. The move appeared in 107 games in The Database. White scored 73%. The most recent game with the line continued 6...Nh6 7.d4 Qe8 8.Bg5+ Kd6 9.Qxe8, Black resigned ffdallagnol - praiseanosyk, FICS, 2014.
The answer to the question of the best continuation for White in this line remains unsettled, although all four moves given have been successful in practice.
Some lines in the Jerome Gambit and related openings get a lot of attention on this blog, while others get short shrift. Below, Black uses a rare defense to the Blackburne Shilling Jerome Gambit, White misses the best response, and, after a relatively short tussle, the first player loses.
Clearly I have some educational work to do.

The Blackburne Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke7
It is rare that I can give the history of my attention to a particular line in short order, but with "Blackburne Shilling Jerome Gambit (2)", "Please don't do that", "My Turn Again" and "BSG: Later on in theDiscussion" that's about it.
Reflecting how often Bill Wall mines The Database for ideas for play (see "Hit Me With Your Best Shot"), I feel compelled to point out that I did not provide ffdallagnol with the games collection so that he could ambush lorecai with something rare.
6.Qh5
Looks aggressive, but best, leading to only a small edge for Black, is 6.c3, as Houdini 3 lays out: 6...d6 7.Nc4 Ne6 8.d4 Nf6 9.f4 d5 10.Ne5 dxe4 11.f5 Nc5 12.0-0 Nd3 13.Nxd3 exd3 14.Qxd3 Kf7 15.Bg5 Be7 16.Nd2 Re8 17.Rae1 Kg8 18.Bxf6 gxf6 19.Qe4 Qd6 20.Rf3 Kh8 21.Rg3 Bd7 . I'll have to track down some of the relevant games.
6...Qe8 7.Qg5+
Wanting to keep the attack alive, but best play at this point, alas, was exchanging the Queens followed by 8.Kd1.
7...Nf6 8.Na3 d6 9.Nec4
9...b5 10.Ne3 b4
This pawn charge is fun, but not best.
11.Nd5+
White can stir up more mischief with 11.e5 bxa3 12.exf6+ gxf6 although he still would be worse.
11...Kd7 12.Nxf6+ gxf6 13.Qxf6
Hoping the attack on the Rook on h8 will give him time to save his Knight on a3. In a way, he succeeds.
13...Qxe4+ 14.Kf1 Qe2+ 15.Kg1 Qe1 checkmate
