Could you post the line that got you here?
Thought not
I'm guessing that d2 pawn has been captured on d4 and then white played e5. I would imagine d5 is the response.
I believe the line is 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d4 exd4 6. e5
It was similar to that, although it was slightly different move order, transposed from the Scotch Gambit.
d5 huh? Thanks! I guess I considered that too risky, en passant crossed my mind, opening the e-file.
I am not sure about the posted diagram unless white blundered in the opening. White plays d4 following c3, yet the pawn is still at d2.
If the line indicated is after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.e5 d5! is strong. 7.Bb5 Ne4 and you get a Sveshnikov.
White has presumably entered the wrong position onto his diagram. (OP: you can edit the d2-pawn out.)
Yeah sorry, edited.
A Scotch Gambit transposition? What went on there then?!
I assume:
1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 Bc5 5. c3 Nf6 6. e5
Usually 6. cxd4 is preferred in that position, but oh well. Both are playable.
Aha! I would never have guessed that! So you transposed twice!
Centre Game -> Scotch Gambit -> Giuoco Piano!
Yeah, he kept me guessing all the time! Openings aren't my strong suit to be honest and this one just puzzled me. Worked for him though.
EDIT: Here is the full line (the full game, embarrassing though it is) for Afaf.
