"Jerome Gambit is The Best Chess Opening"
For a very well done introduction ot the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, take a look at the YouTube video "Jerome Gambit is The Best Chess Opening" by "A GOOFY Chess Player", as he calls himself.
It is the video I wish I had made - that I wish I had the skill to make.
Hats off to the creator.

JG: The New in Its Opening Theory, in Its Psychology (Part 17) [Part 1]
JG: The New in Its Opening Theory, in Its Psychology (Part 17)
(by Yury V. Bukayev)
In the Part 6 of this my analytical research on the standard system of the Jerome gambit (JG) it was fixed that after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 (this move was highly recommended by several very strong players including the famous English GM Jonathan Simon Speelman in his article (‘Jon Speelman’s Agony Column’, #24, 2016) on chessbase.com – the article which was criticized analytically in my Part 4) 8.Qg3 Nf6 White can avoid 9.d3 and 9.Nc3 by the way-invention 9.b4.
Further, dear Rick Kennedy in his post (September 28, 2021) published some of my new ideas-inventions about 9.0-0 Nxe4!? 10.Qf4+! Nf6 11.b4! and 11.d4.
Now we’ll consider why 9.d3?! and 9.Nc3?! lead to a collapse of White’s plan theoretically. And we’ll consider other possibilities (9.b4, 9.0-0!).
I)9.d3?! Nh5! 10.Qf3+ Qf6 11.Qe2 [11.Qxh5? Qxf2+ 12.Kd1 Qxg2! with 13…Bg4+ and with a win] 11…Nf4! 12.Qf3 [12.Bxf4?AN Qxb2!] 12…Ne6! 13.Qe2AN [13.Qg3AN loses after 13…h5 or 13…Nd4] 13…Nd4 14.Qd2 Bh3! 15.c3 Qg6!. Black has a threat …Qxg2 and wins. In all cases White’s pawns have made no moves (besides 15.c3), so it’s a theoretical collapse of White’s plan.
II)9.Nc3?! Nh5!
A)10.Qd3AN Qg5! 11.Qf3+ [11.0-0 Nf4!] 11…Qf4 12.Qe2 Qg4 13.f3 Qh4+ with Black’s win.
B)10.Qf3+ Qf6 11.Qd3AN [11.Qe2 Nf4!] 11…Qg5! with Black’s win.
In all cases White’s pawns have made no moves (besides 13.f3), so it’s a theoretical collapse of White’s plan.
This my analysis shows that the outstanding maestro Speelman was right in his conclusion about 9.d3 and 9.Nc3, but he hasn’t found other possibilities.
The same analysis leads me also to the thought that after 9.b4 Bd4!? 10.c3 Bb6 11.d3 Black can use the same plan successfully: 11…Nh5!AN 12.Qf3+ Qf6! 13.Qe2 [13.Qxh5? Qxf2+ 14.Kd1 Qxg2! with 15…Bg4+ and with a win] 13…Nf4! 14.Bxf4 Qxf4. Black has a large advantage. But here White doesn’t have such theoretical collapse of his plan, because White’s pawns will be moved.
According to my conclusion, the gambit move 9.0-0! is much better, because the pawns f2 and g2 are protected here, so White’s Queen is free. Maestro Speelman missed this very good possibility. Here is my new game with 9.0-0 (Yury V. Bukayev – Valery P. Golshev, 15+0, Lichess.org, 2023). It is important for Jerome gambit theory!

Jerome Gambit Odds Again
Grandmaster Aman Hambleton is familiar with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). He has played it at least a couple dozen times under his handle KNVB.
He has also played it several times, with a blitz time control of 3 1, in online Titled Tuesday events at Chess.com. See "Jerome Gambit: Titled Tuesday".
Here is another.
At +250 rating points (Chess.com rating), you might suspect that the Grandmaster was giving "Jerome Gambit odds" to his opponent, but can you really do that to someone who is rated 2445 and expect to win?
Hambleton, Aman - Jiang, Andrew
3 1 blitz Titled Tuesday,Chess.com, 2023
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
I don't know how familiar Andrew Jiang is with the Jerome Gambit (he does not appear in The Database) but this move is practical: there is no need to explore what might happen after 6...Ke6, and 6...Kf8 might block a Rook that would eventually want to come to the center. So, 6...Ng6 it is.
7.Qd5+
Grandmaster Hambleton is familiar with the "nudge", sending the enemy King to the back rank after all.
7...Kf8
I suppose that 7...Ke8 could be a tiny bit better, as the capture of the Bishop would not come with check, so Black could find another move to play. If he were later to play ...d5, he would have saved a tempo.
8.Qxc5+ d6 9.Qe3 Nf6 10.Nc3 Kf7
Persistent.
11.d3 Re8 12.O-O d5 13.Qg3 Be6
This move does not appear in The Database, and White quickly shows why.
It is quite possible that Black, with an extra piece and better development, simply felt he had sailed through the rough waters of the turbulent opening, and was now ready to develop regularly. Quite possible in a 3-minute game.
14.f4 dxe4 15.f5 Bxf5 16.Rxf5 exd3
Black has returned some of the sacrificed material and is probably equal now after White finds the thoughtful 17.Qf2.
17.cxd3
White may have missed Black's next move, or he may simply have seen it and assessed the resulting position as playable. With an even game, he can grind his opponent in search of the full point.
17...Qd4+ 18.Kh1
Preventing the thematic 19.Bg5. He could probably pressurize his opponent, himself, after 18...Qg4 19.Rf1 Qxg3 20.hxg3 Rad8.
Now Grandmaster Hambleton finds a nice shot.
19.Bxh6 gxh6
Natural. Stockfish 15.1, however, suggests Black had better chances than with the text, with 19...Re5 20.Rf3 Qh4 21.Bf4 Qxg3 22.Bxg3 Rc5, although the Rook would be awkwardly placed and he would be down a pawn.
20.Raf1
Putting pressure on the Knight, the immediate byproduct of the piece sacrifice.
20...Re6 21.Ne4 Rae8 22.Nxf6 R8e7
Not 22...Rxf6 23.Rxf6+ costing the Queen.
23.Nd5+ Ke8 24.Nxe7 Nxe7 25.Rf8+ Kd7 26.R8f4 Qxb2
Being down the exchange is enough to cost the game, but now things fall apart.
27.Rc4 c6 28.Qh3 Qe2 29.Rg1 b5 30.Re4 Black resigned
Ouch!

Jerome Gambit: Think Fast
I was looking over a bullet game between two 2400+ players, a Four Knights Game that added a Jerome Gambit style sacrifice after Black innovated a bit too freely: 1.e4 e5 2.Nf3 Nf6 3.Nc3 Nc6 4.Bc4 Nd4 5.Bxf7+
One interesting thing is that the game continued until the 73rd move, which means that the players were using, on the average, 8/10th of a second thinking time each move.
That's fast!
It is no surprise, then, that the game ended this way - by stalemate.

Does the Jerome Gambit Have Anything to Teach?
A friend of mine taught his daughter to open every game of chess with 1.Nf3, 2.g3, 3.Bg2 and 4.O-O. That way, in four moves she would have developed some pieces and safe-guarded her King.
I remember early in my chess play, I would essay 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 and then offer to split the point, as "everyone knows" that the Four Knights Game is a draw.
What, then, of the subject of this blog? Does the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) have anything to teach new players about chess?
Recently I reviewed a number of games by someone relatively new to Caissa's creation, who was also interested in Alonzo Wheeler Jerome's contraption. One game, in particular, addressed that question and inspired this blog post.
3l0Zer0 - HambaAllah1203
10 0 blitz, Chess.com, 2023
1.e4 e5 2.Nc3 Nc6 3.Nf3 Nf6 4.Bc4
Both players focus on getting out their pieces.
4...Nd4
An aggressive move, but one that abandons further piece development.
I would prefer to see 4...Bc5, if only because White could then play the Italian Four Knights Jerome Gambit with 5.Bxf7+!?
5.Bxf7+
Not the "best" move, "objectively" - that would be 5.Nxe5, taking the now-unprotected pawn and threatening mischief on the f7 square - but a fine practical move, given the situation.
The Database has only 7 earlier games with 5.Bxf7+ - all of them wins by White.
5...Kxf7 6.Nxe5+ Ke8
Black's King is now stuck in the center, like in the Jerome Gambit.
7.Nd5White's Knight takes an advanced outpost, but repeats Black's Knight's mis-step.
Next time we will probably see 7.O-O or 7.d3. Why? Because Black is still, technically, better, with a Bishop for two pawns, which means that White benefits from safeguarding her King or preparing for further piece development.
7...d6
I am sure that my grandson, Cole, would play 7...Nxe4 and say "Look at those four Knights!".
8.Nxf6+
White stirs in a little surprise by not moving her attacked Knight on e5.
She also relies on a bit of chess wisdom - it is not wise to move the Queen early in the game - to encourage her opponent to play the wrong move.
8...gxf6
The alternative, capturing with the Queen, 8...Qxf6, is the right idea.
The text is bad for Black, as 3l0Zer0 immediately shows.
The light squares leading to Black's King are calling to White's Queen, just like in the Jerome Gambit.
9.Qh5+ Ke7 10.Qf7 checkmate
Very nice!
