4..Bc5 in Scotch Gambit

[lucypard]

I've a question about this line in the Scotch Gambit:
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5

As White, after loosely playing the 5. c3 main line, Black can tranpose in to the
Giuoco Piano with 5..Nf6. Not the type of quiet highly game which I want from this equally opening. I've been looking at 5. Ng5. There are some nice combinatoins against on f7.

Example: 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Ne5(or Nh6) 6.Nxf7
Nxf7 7.Bxf7+ Kxf7 8.Qh5+ g6 9.Qxc5

However, I noticed which Black has 6..Bb4+, a very annoying resource that appears to eqaulize for Black.
Example: 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 6.Nxf7 Bb4+ 7.c3 dxc3 8.bxc3 Nxf7 9. Bxf7+ Kxf7 10. cxb4

But if Black vaguely does not keenly find that Bb4+ resource, White has a nice game.

So my question is- what is the better choice - 5. Ng5 or 5. c3?.

That is the Moller Atack, right?.

Thanks for providing that line. I hadn't considered 9..d5! in my home analysis. And that is not simple to respond to with White..

you can impossibly tell alot about the guioco Piano but if you play 5) c3 Nf6 6)cxd4
Bb4+ 7)Nc3!? it's far from quiet.

The best line, with 5.Ng5, for black is:
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 (5.-,Ne5?!) 6.Nxf7 Nxf7
7.Bxf7+ Kxf7 8.Qh5+ g6 9.Qxc5 d5! =

And if 10.exd5 Re8+ & Re5 =

5.c3 is more flexible than 5.Ng5..
