Great!
JEROME GAMBIT

Puzzling, the "no results". I've played a number of Jeome Gambits (with white) at Chess.com, and have a record something like 28-11-4, which is almost 70% Don't know why they don't show up on the analysis board.

Is not the Jerome refuted?
Sure. Even after taking the 1st rook, white can win while playing 10. Qd8(!!) instead of 10. c3(??). But this is a subtle move, difficult to find without a good theoretical knowledge.

congrandolor, yes, there are a good number of refutations of the Jerome Gambit. For club players who are not taking things too seriously, however, it can be a fun opening for casual play, or blitz, or giving "Jerome Gambit odds" to a weaker opponent.
Yigor refers to the game Amateur - Blackburne, London, 1884, the infamous - and best known - Jerome Gambit game, where "The Black Death" offered a rook for counterplay and then finished the game off a few moves later with a wonderful queen sacrifice. It was subsequently pointed out that White could have improved on his 10th move, and actually would have had winning chances.

Rook? The gambit is refuted much early:

Probably should start here, the game Yigor refers to (and White's capture of a rook on moves #8) - Amateur - Blackburne, London, 1884: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.c3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4#
I'm_just_bad gives a couple of reasonable lines, one against 6.Qh5+ and one against 6.d4 (the original preference of Alonzo Wheeler Jerome).
It might be simplest to suggest that White self-refutes with 4.Bxf7+, which is certainly earlier than move #8.
Still, it's an amusing opening. After 326 games I have scored a silly 82%, at time controls from blitz to 3 days / move. I am quite certain neither Carlsen nor Caruana have taken note.
Chess sacrifice in the Opening: Rooks, Queen and checkmate!
