New to forum and need help with the Stafford Gambit

Hi all,
I joinned awhile back, but I'm just now getting around to posting and meeting everyone.
I hope everyone is safe while this corona mess is going on. Anyway, here's my Q:

The Stafford gambit is predicated on the white knight capturing the black knight on c6.
But when playing myself, I can’t figure out how it works if the white knight goes back to
f3 after capturing the pawn on e5.

Here’s the moves in the video:
1.e4 e5
2.Nf3 Nf6
3.Nxe5 Nc6
4.Nxc6

But what if the white knight does this instead:
1.e4 e5
2.Nf3 Nf6
3.Nxe5 Nc6
4.Nf3

I understand the other scenarios in this youtube the the above is not being taught:

Thanks in advance

What do you think?

White has moved the same piece 3 times in the first 4 moves, and gave up his opening advantage by falling behind in development.

I don’t understand your question, “What do you think?”

According to the video, this gambit leads to a quick checkmate.
But I can’t figure out how to get there when the knight moves back to f3.
So, is the gambit null and void at that point?

I’m trying to understand the theory of the Stafford by playing myself,
and I can’t figure out how to make it work in this case.

Yes, the 0-1 game is what I was reffering to.
And I have studied the different variations in the video.
But I really lose the flow at 4.Nf3 ???

Thanks for letting me know there's no quick mate at this point.
I guess that's why I had a hard time finding one, even though I'm playing myself.

Yeah, I understand those scenarios where the white knight cooperates. 

But 4.Nf3  Nxe4 and I lose my knight, so I'm stuck here 4.Nf3  ???

What is a good next couple of moves to keep the advantage for black?

Or is it that the Stafford Gambit fails at this point and a different strategy is needed?

Eric Rosen advocates strongly for the Stafford. His advice is surprisingly more fruitful than a video dedicated solely to elucidating the gambit and all the turning points and what not. 

Thanks 

I will check him out more, but what I've seen so far does not include the knight going back to f3.

4.Nf3

It is pretty simple. You play the main line, but Black has played Nc6 instead of d6, so it's a better position for him (can play d5 in one move).

Never mind its just bad lol

Take e4

On move 4, I usually take the knight, but it causes my kingside to get really weak as black brings in his bishop, knight, and queen, sometimes even pushing the h-pawn. I think playing mainline Petrov theory is not ideal against the Stafford.

Stafford Gambit is just bad. Accept, defend, win.
