I am pretty much set that I want to learn italian
What to play in Italian as white

Against two knights, fried liver and d3 are both fine. Fried liver might get you some easy wins for your level but I honestly think d3 is a slightly better option because it’s more principled. I would say d3 but fried liver is good too.
Against Bc5, the Evans Gambit might be a bit harder to conceptualise and stuff but it’s still an awesome opening. I would say Guccio piano, slow Italian or some other gambit but the evans is one of my favourite openings and is also completely good 👍 🔥
In general just play what you want ig. Maybe alternate between 2. If you ask me I would play d3 against two knights and Guccio piano or Guccio pianissimo vs Guccio piano. But maybe that’s just me.
I am 600-700 chess elo in rapid. I don't know what to play. Against 2 knights defense should i do fried liver or d3. Against bc5 should i learn evans gambit or just play giuoco piano
