1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
The Jerome Gambit, not the "quiet game".
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Ng6
Black realizes he has to give back a piece, and "volunteers" the Bishop. The computers suggest that White take the offer, although the (limited) practical results of The Database back the next move in the game: 8.Qxc5 scored 3 - 2; 8.f5 scored 2 - 0.
In bullet chess, there has to be extra value in distressing the enemy King.
8.f5+ Ke7 9.fxg6 Nf6
It is tempting to follow C.J.S. Purdy's advice to find a move that "smites", but it is always best to check your own situation, first.
10.Qxc5+ d6 11.Qe3 Kf8 12.gxh7 Rxh7 13.O-O Kg8
Both sides have castled (one, by hand), and White has a 2 pawn edge.
14.d4 Bg4 15.Nc3 Qd7 16.Bd2 Re8
Taking time to build their positions.
17.Qg3 Nh5 18.Qf2 Nf6 19.Rae1
White declines the offer to pursue a draw with 19.Qg3 Nh5, etc. He is almost immediately rewarded.
19...Qc6 20.e5 Nd5 21.Qf7+ Black resigns
After 21...Kh8 the Queen sac finishes: 22.Qf8+ Rxf8 23.Rxf8 checkmate.
