I would say Vienna, but that's no longer the case sadge
Less Known e4 Openings for white?

The thing about e4 e5 is if you want to be principled, you basically have two knight moves and a bishop move so yeah. It's not like d4 where you can fianchetto (the Catalan) or push a flank pawn.

so true lol

Maybe you could try the Ponziani? (1. e4 e5 2. c3)
That's the Macleod the Ponziani is 1. e4 e5 2. Nf3 Nc6 3. c3, but anyways I will consider that.

The Italian Knight Attack or Giuco Piano Centre Attack is very nice.
Outside of 1.e4
I would say 1.d4 or 1.b3

closed vienna system against e5.
just play g3 d3 Nge2.
it's so hard to play effectively though
I recently studied a lot for white against the major black defenses (Sicilian, French, Caro-Kann, etc.) and against e5 chose to play the King's Gambit but I realized that I may not always want to play such a risky opening, especially in classical games, and the only other thing I play are the Réti and English, and once in a while I want to mix it up. Are there any lesser known e4 white openings that are very good! Thanks!
