Of course, when you checkmate your opponent in a dozen moves, you might very well have proven your point.

5 3 blitz, lichess.org, 2020
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.Bxf7+
This is one of the opening lines that I have classified as "impatient Jerome Gambits" in that White does not wait for ...Bc5 before sacrificing his Bishop.
If Black is not prepared the shock may shorten the game considerably.
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.d4
Black is holding on, but he has to keep his King safe, even at the cost of returning some material.
8...Qf6 9.dxe5+ Qxe5 10.Qxf8+
This works, but 10.Bf4 was even stronger.
10...Qe7
11.Bf4+ Ke6
Stumbling into it.
12.Qf5 checkmate
Okay!
