This course doesn't cover the Slow Italian.
Perunovic aims for the setup e4-Bc4-d3-Nc3-f4-Nf3,
a Vienna / Kings-Gambit-Declined hybrid.
Of course he has to cover 1.e4 e5 2.Bc4 Nf6 3.d3 c6!? 4.Nf3 d5.
(As an extra benefit Perunovic covers the Urusov-Gambit too:
1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Nxe4
This gambit is dangerous, but almost every player declines it.
4...Nc6 is the Two Knights Defence and the standard reply in praxis.
4...Bc5 and 4...Bb4+ might be stronger/simpler than 4...Nc6.
If you are not happy with the Two Knights with 4.d4
then better avoid the Urusov. )
Kravtsiv: The Italian Renaissance
1: Move Orders, Tricks and Alternatives
(Quality Chess)
gives the same repertoire as Perunovic,
except the Urusov Gambit.
But Kravtsiv's main recommendation is to transpose to the Slow Italian game, which he analyses very detailed in book 2.
I am not so sure that a transposition to the Slow Italian is always possible if Black plays Nf6, Bc5 but delays Nc6.
