1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
This is referred to as the "Semi-Italian Opening" in Euwe & Meiden's Chess Master vs Chess Amateur (1963). It is a cautious attempt to keep a White piece off of g5, at the risk of wasting some time and possibly weakening the Kingside, if Black should castle there.
4.Nc3 Nd4
Wow, Black goes from "shy" to "outgoing" in one move. He plays the Blackburne Shilling Gambit, with the addition of Nc3 and ...h6. This may well be effective psychology in a bullet game (surprise your opponent, make him take precious time to figure out a novel position), but it is very risky play, nonetheless: In 20 previous games in The Database, Black scored only 20%
Stockfish 10 rates the first player's position as 3 pawns better at this point.
5.Bxf7+
One good surprise deserves another. White gives the "Jerome treatment", creating a sort of "Semi-Italian Blackmar Shilling Jerome Gambit" hybrid.
Why do such a thing? First, White is familiar with Jerome Gambit and Jerome-like themes and tactics (and his opponent may not be). Second, the "proper" response to Black's 4th move, at least as laid out by Stockfish 10, is stylized along BSG lines, and may well not be to the first player's taste. The computer recommends 5.Nxe5 Qg5 (thematic BSG) 6.Bxf7+ Kd8 7.Ng4 Nf6 8.Ne3 Bc5 9.O-O Rf8 10.f4 Qh4 11.b4 Bb6 12.Bg6 d6 13.e5 Bg4 14.Qe1 Qxe1 15.Rxe1 dxe5 16.fxe5 Bh5 17. exf6 Bxg6 18.fxg7 Rg8 19.Na4 Rxg7 20.Bb2 Rd7 where White is up two pawns.
5...Kxf7 6.Nxe5+ Ke8
Home again - and walking into a checkmate.
The computer humorously recommends 6...Ke6 7.f4 Qh4+ 8.g3 Qh3 9.Nd5 Qg2 10.Qg4+ Kd6 11.Qg6+ Nf6 12.Nc4+ Kc6 13.Ne5+
heading toward a draw by repetition.
White is now rewarded for his bold play.
7.Qh5+ Ke7 8.Qf7+ Kd6 9.Nc4+ Kc6 10.Qd5 checkmate
I was pleased to see that The Database contained more than a few games with the attacking (against the Semi-Italian / Philidor Defense) move 6.Bxf7+ mentioned by Max Euwe and Walter Meiden in their 1963 book Chess Master vs Chess Amateur, and covered in the previous post (see "The Jerome Gambit Treatment - Unbelieveable!").
When we look a bit further, at 6...Kxf7 7.Nxe5+ Kf6 - the line with Black's best defense - it is reassuring to find two games with Euwe and Meiden's recommended 8.Nd3.
It is interesting that in the first of those games Black performed the prudent retreat of his King to h7 (an idea mentioned in the previous post); and then, from a better position, he benefitted from an oversight by White to score the point.

In the second game, clearly the clock played a factor in the blitz game, as both players tossed the advantage (for White, various checkmates) back and forth before splitting the point, as the notes show.

There are also 3 games in The Database with Stockfish 6's choice, and perhaps the best move, 8.Qf3+!? Alas, none of the attackers were able to discover the recommended 8...Kxe5 9.Qf7!? and although they fought the good fight, only the experienced drumme (457 games in The Database) was able to score - and that was a time forfeit win from a worse position.

I stumbled over the following game while looking for a possible recent Semi-Italian Jerome Gambit game example. White faced a Philidor Defense variant and dispatched it quickly.
What I recalled in my notes to move 6 got me chuckling, but what I found in my notes to move 7 sent my mind reeling: The "Jerome treatment" leads to this - Unbelieveable!
Take a look and see.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.d4
Sometimes when I am expecting Black to reply with 3...Bc5, I am met with 3...h6, the Semi-Italian Opening, instead. I usually continue with my development with 4.0-0 and hope for Black to fall in with my wishes. Occasionally I see 4...Nf6 and have to try 5.Nc3 before I see 5...Bc5 (and am then able to play 6.Bxf7+).
The earlier series on this blog, "A Jerome Look At The Semi-Italian Opening (Parts 1, 2, 3, 4 5 and 6)", is well worth visiting for history, analysis and games.
I took a quick look at The Database, and noticed:
There are 1,569 games with (or transposing to) 4.d4, with White scoring 64%; there are 352 games with 4.0-0, with White scoring 70%; and there are 349 games with 4.Nc3, with White scoring 61%.
4...d6
The Database showed only 153 games with this move (not the best), with White scoring 70%. The more popular (and stronger) alternative, 4...exd4, appeared in 1,062 games, where White scored 57%.
5.dxe5 dxe5 6.Bxf7+
Of course, the straight-forward 6.Qxd8+ Kxd8 (or 6...Nxd8 7.Nxe5) 7.Bxf7 would win a pawn for White, but todotranquilo prefers to play like Jerome.
(Due to sampling bias, The Database does not have any games with 6.Qxd8+, but a quick look at ChessBase's online database gives 63 games with that move; White scores 86%. The two databases are vastly different, making comparisons dicey, but this peek gives an indication of the validity of 6.Qxd8+.)
Interestingly enough, 6.Bxf7+ was embraced in Chess Master vs Chess Amateur (1963), by Max Euwe and Walter Meiden
White could act even more energetically [than 6.Qxd8+ etc.] by playing 6.Bxf7+ Kxf7 7.Nxe5+, and Black is in great trouble, for (a) 7...Nxe5? 8.Qxd8 or (b) 7...Ke7 8.Ng6+, or (c) 7...Ke8 8.Qh5+ Ke7 9.Ng6+. After (d) 7...Kf6, the continuation is less clear. This does not mean that the sacrifice would be incorrect, since after 8.Nd3, White has two Pawns for a piece and the Black King is badly placed. On the other hand, a safe win of a Pawn as in the other variations, might be preferable.
Stay with me, there is more.
For starters, due to the magic of transpositions, there are 2,025 games in The Database with this position (after 6.Bxf7+), and White scores 41% - a reason, from a practical point of view, that Readers might consider the mundane 6.Qxd8+ over the dashing 6.Bxf7+. (The online ChessBase database has only one game with the position, a win for White.)
Of course, "from a practical point of view" it might also be wise to avoid the Jerome Gambit altogether; but where is the fun in that??
6...Kxf7 7.Nxe5+ Ke8
As mentioned above, 7...Kf6 is probably Black's strongest reply. Surprisingly, after the suggested pragmatic 8.Nd3, Stockfish 6 recommends 8...Kg6 and 9...Kh7 for Black, maintaining that the defense holds, and that the second player would have the advantage!
To be fair, the authors of Chess Master vs Chess Amateur were tidying up an offhand line in an offhand variation, not preparing for a tournament or writing an opening manual. But, what is the best response to 7...Kf6 ?
The best move seems to be 8.Qf3+!?, sacrificing a piece in true Jerome Gambit style! It turns out that anything else other than taking the piece with 8...Kxe5 for Black leads to checkmate. White's best move then is keep-the-enemy-King-in-the-middle 9.Qf7!?
analysis diagram
I gave the crazy position - White has sacrificed two pieces, Black's King is in mortal danger - to Stockfish 6, and here is just a surface view of what it found (the game is even) 9...Nf6 (9...Bb4+ 10.Nc3 Bxc3+ 11.bxc3 Nf6 12.f4+ Kxe4 13.0–0 Qg8 14.Qg6+ Kd5 15.Rd1+ Nd4 16.Rxd4+ Kc6 17.Qd3 Be6 18.f5 Rd8 19.fxe6 Rxd4 20.cxd4 Qxe6 White has an edge) 10.f4+ Kd6 (10...Kxe4 11.Nd2+ Qxd2+ the only move to avoid mate 12.Bxd2) 11.e5+ Nxe5 (11...Kc5 12.Be3+ Nd4 13.Nc3 Bg4 14.h3 White is better) 12.fxe5+ Kc6 13.Qc4+ (13.exf6? Bc5 Black is better) 13...Bc5 14.Be3 b6 15.Bxc5 Qd5 16.Qxd5+ Nxd5 17.Bf2 Ba6 18.Na3 Rhe8 19.0–0–0 Rxe5=
Please. Even that is too much. Is there any wonder why I play 4.0-0 ?
8.Qh5+ g6
The line Euwe and Meiden mention, 8...Ke7 9.Ng6+ is clearly good for White, who wins a Rook. They can be forgiven for not having a computer program which would have told them that the alternative 9.Qf7+ would lead to checkmate in a dozen moves.
9.Qxg6+ Black resigned
Dear Defender,
This is a blog for those interested in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and related openings.
I am sure that you can tell, if you read a few posts, that I like the Jerome, I play the Jerome, and I celebrate Jerome Gambit victories.
If you stick around this blog and look a bit deeper, you will also see that I try to be fair in my evaluations. After all, the Jerome Gambit was practically born refuted.
So, this post is for you, and everyone else who wishes to rain on my parade. Just a little tip...

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening, the name given in Euwe and Meiden's Chess Master vs Chess Amateur (1974).
4.0-0 Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit, so named because it transposes after the Black King captures the White Bishop to a "modern" variation of the Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 – "classical" Jerome Gambit variations continue with 5.Nxe5+, "modern" Jerome Gambit variations try something else – 5...h6, etc.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6 8.Qxe5
Here, Black resigned. He looks to lose a Rook or a Bishop, remaining with an uneasy King, down a couple of pawns.
But – look closer.
As I pointed out in the notes to my game with alekbb a year ago (and a couple of times before that, going back 3 years) Black is actually better in the final diagram.
The resolute 8...Bf8 ("box" as they say) saves the Black Bishop and poisons the Black Rook: 9.Qxh8? Bg7 10.Qh7 Nf6 and the White Queen is lost.
