The London, The English and the Kings Indian Defense or attack both are good. Hope this helps
In need of a solid opening for white

You don't win by changing your opening (unless it is a really bad opening). Try to understand why your performance is bad and use it as an opportunity to learn some more chess - and not just a new opening.

True, but recently my opening just hasn't been getting me great results, but at the start I was getting great results from it, as ive been climbing up the rating chart, its gone downhillI. I analyse my games, have done lots of studying. idk, just wanna learn another opening and see if anything changes

So recently I've been performing quite badly with my opening that I usally play, the queens gambit, and would like to try out another opening to see if that would improve my win rate. In comparison I have a 45% win rate with the Queens gambit, which might not sound so bad, but in comparison with my 65% win rate with the French defence, it's quite bad. Would appreciate very much if you could name some solid openings for white!
What about the nimzo larsen? Its a fairly easy opening to play that has alot of attacking chances for both sides.

I like the Italian and the London
Cool. But yknow i like more action in my positions.

The Queen's Gambit is a top quality opening. It's not the opening which is the problem.
You need to improve in other aspects of the game instead of expecting to win easily with another opening.

The opening is everything, learning your opening gets you comfortable with your openings middlegame and you wont just be lost and confused.

I think that learning a opening is way more important due to the fact that after the opening, the player will get a list of general ideas to strive for after the ending ends. Like Ne3 in the ruy lopez or c3 or something.

Yes, learning the opening properly is important. The point is that the Queen's Gambit is a good opening so it makes no sense to expect to suddenly do better by changing openings.

- Queen's Gambit
- Ruy Lopez
- Italian
- Scotch
are amongst the best openings available.
More than not, the enemies KNOW the book moves, soo i reccomend smh like 1. b3 because its just soo freaking poggers.

Who cares if they know the book moves? That's the point. You get to a position you're comfortable with.
If I play Ruy Lopez and someone plays a main line Closed Ruy against me then I'm happy. It's not a decisive advantage but I get the kind of position I want and it's going to be a good game.
More often than not they don't do that because they don't know all the book moves like you say they do.
Nimzo-Larsen is an ok opening but I wouldn't be too keen on it as it surrenders a lot of the centre to black. This is not good principles generally. Even though this is ok in some circumstances, it's not ok most of the time. Eventually people are going to know the Nimzo-Larsen book moves just as well as those lines I mentioned and then they are going to have an easier game as Nimzo-Larsen is not that hard to play against.
