Then Black decides to return another piece - for what reason, it is not clear. The decision eventually costs him another piece, and the game.
Again, inexplicable.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6
Black's Queen often comes to f6 when defending against the Jerome. The not-so-subtle threat is ...Nf6+, winning White's Queen.
8.Qe3 Nh6 9.O-O
There are only 3 other games in The Database that have the position after 8...Nh6, all games played by stretto. One of them:
9.Nc3 Rf8 10.Nd5 Qd8 11.O-O c6 12.Nf4 Kg8 13.Nh5 d6 14.Nxg7 Kxg7 15.Qxh6+ Kg8 16.f4 Nf7 17.Qh5 Qf6 18.f5 Kh8 19.Rf3 Rg8 20.Rh3 Rg7 21.Bf4 Bd7 22.Rd1 Rag8 23.g3 Be8 24.Qf3 Rg4 25.Be3 Ne5 26.Qf2 a6 27.c4 R4g7 28.b3 Ng4 29.Bd4 Nxf2 30.Bxf6 Nxh3+ 31.Kg2 Ng5 32.Bxg7+ Rxg7 33.Rxd6 Nxe4 34.Rd8 Rg8 35.Kf3 Bh5+ 36.Kxe4 Rxd8 37.f6 Kg8 38.Ke5 Kf7 39.h3 Bd1 40.g4 Bc2 41.g5 Bb1 42.a4 Ba2 43.b4 Bxc4 44.h4 Bb3 45.h5 Bxa4 46.g6+ hxg6 47.hxg6+ Kxg6 48.Ke6 Bb3+ 49.Ke7 Rg8 50.f7 b6 51.fxg8=Q+ Black forfeited on time, stretto - Tollens, FICS, 2008.
9...Nhg4
It is always tempting to harass the White Queen.

10...h5 11. h3 h4
Black's plan is simple, to drive off the enemy Queen and attack the enemy King. His Rook is well-placed for attack, and his King is not in danger, at least for now. He is willing to return the sacrificed piece in order to heat things up.
12.Qb3+ Kf8 13.f4 Nc6 14.hxg4 Nd4 15.Qe3 h3
16.gxh3 Qh4 17.Rf2 d5 18.f5
A messy position, but White may be a little bit better.
18...Bxf5
I am not sure what Black is up to, but it does not turn out well. Perhaps a time issue?
Stockfish 8 suggests that Black can keep the deficit to a pawn and a half with the line 18...Qxh3 19.Qxh3 Rxh3 20.Kg2 Rh4 21.Kg3 Rh1 22.Be3 Rg1+ 23.Kh3 Nb5 24.Rd2 Re1 25.Bf2 Rc1 26.Na3!?

19.Qxd4
The Black Bishop is not going anywhere.
19...Qg3+ 20.Kf1 Qxh3+ 21.Ke1 Qh1+ 22.Rf1 Qh4+ 23.Qf2 Qh3
White's Queenside pieces all are at home, yet he has a won game.
