I need a good opening for white. (intermediate level)

nope, -0.5

At intermediate level, that -0.5 won't mean a whole lot as it's hard to attack the center successfully, and most players won't play c6 or take with the g pawn

playing hope chess is not the way to get better

It's not hope chess though. Even the position you showed is completely playable and white has advantages in certain places

that position is not playable as white at all

you have weak pawns, less active, and black has the initative

The only issue is that your little position has never been reached a single time in the lichess database despite the richter veresov having been played 3.1 million times

Hey Samuel, let’s argue! Grrr 😡

I don’t think Vienna is mediocre, I think it’s good and practical. Let’s argue 🥊

The main opening I recommend would be this (I believe it's called the Colle-Zuckertort):

Your plan is to play Ne5 followed by f4, lift the rook up onto f3, and then swing the queen over to black's kingside. Along with your two bishops and the option of playing g4 and g5, you should be able to crush black with a simple kingside attack and checkmate. It's a great opening because there isn't much theory, so you can focus more on developing your understanding of the middlegame plans and tactics which are more essential for beginner-intermediate players. It's also relatively systematic, so you can play it against pretty much anything that black does. Would highly recommend, especially over things such as the Ruy Lopez or Queen's Gambit.

woops, now you dont get what you want
