Is Black's defense to the Jerome Gambit in the following game acceptable?
Of course.
Does it give him practical chances?
Of course. (Check the notes, and you will find a couple of draws against Bill Wall, and even a very rare win against him.)
Does Black win?
Of course not.
Once again, the defender is able to grasp loss from the jaws of victory - as so often happens in the Jerome Gambit.

Black has many ways to return a piece. This one activates his Queen.

11.Re1 d6 12.f4 Neg4 13.Bd4 Kg8
Black has castled-by-hand. If he works on his development, he can make something of his piece-for-a-pawn advantage.
White's job is to disrupt Black's plans.
14.h3 Nh6 15.g4 c5 16.Bf2 Be6
This is a funny oversight. Often, in the Jerome Gambit, Black has to be careful that when he plays his Bishop to e6, that it doesn't become a victim to a pawn fork. This move allows a fork - of the two Knights.
17.g5 Nf7
Possibly 17...Nxe4 18.Nxe4 Ne5 was better.
18.gxf6 Qxf6 19.f5
19...Qg5+
Energetic, and focused on the enemy King, but possibly the start of some "smites" that are too shallowly considered.
20.Kh2 Bc4 21.b3 Qf4+
White's answer is sufficient.
Black's attack on the King is an illusion, as will be seen.
22.Bg3 Qh6 23.bxc4 Ng5 24.h4 Re7 25.Qg4 Nf7 26.Nd5 Ree8 27.Bf4 Black resigned
Black's Queen is in trouble. There is an immediate defense, but, in the long run, White's pressure on the Kingside will prevail, e.g. 27...g5 28.Bxg5 Qg7 29.Qh5 Nxg5 30.hxg5 Re5 (to avoid the Knight fork) 31.Nf6+ Kh8 32.g6.
