I was in your shoes less than a year ago. This is what I did:

It might be helpful to you as well.
Openings are not that important for a beginner, until you get pretty good. I mean, sure, you should learn first couple of moves of the variation you would like to play and then improvise. What you should know however are opening principles. In short, develop as fast as you can, control the center, castle and connect your rooks. If you want to read a bit more, then:

Anyway, welcome and have a great time improving your game.
Hey I'm new - but not new to chess. Where to go from here?

Hey mate thanks a lot! My post disappeared but trying again.
Very very useful stuff you provide on your blog, amazing!
Thanks for the principles and thinking, really helped me a lot. I just thought about the openings that I should have some sort of strategy/system for my own and Had to have a system to play "by the rules". All these stuff were new to me when I started to read the past week.
Will def go more into your blog and read more, thanks again it really helped!!
So yeah, always been a fan of chess, IQ-games and practices and math. But, I lost my playing and haven't played in like, 15-20 years? I'm 31 now.
I recently watched Queen's Gambit which had me really digging deep into chess. Talked with some chess friends and also downloaded Mr Wolf app which I found incredibly good, I absolutely love it.
This was my first game - not super proud for beginner level but I managed to win which was nice.
I did NOT study anything prior this game, just with feeling. But after a week of learning some different kind of openings (black and white) I favored some more (Caro and Colle) and also looking at the Scandi and Kings Indian and Sicilian Accelerated Dragon. Accelerated Sicilian seems a bit too advanced for a "beginner" or? I really liked what I saw from Caro-Kann and Colle, one has some newer improved Phoenix Attack to it I think it's Colle.
And after analyzing this game I would definitely played differently in the beginning with some moves for a slightly better win and not losing that much.
I know the foundation etc but want to progress a bit. Would doing the tutorials here be good and continue with Mr Wolf? Or can someone point me to a book or two, I have Silman's "The Amateur's Mind" which I heard is good and some others. But the notation makes me dizzy!
My thinking is like, is practice alone gonna make me a better player only by that (puzzles, problems and just play games and do tutorials here) or should I try to "find a good opening and defense strategy" too like the ones I found and go from there and "learn them by heart"?
Or is there like 1-2 strategies/systems I could use as both white or black and be good at it and just learn that and go with that and use it as "my strategy" in the future plays? If there is one of course.
I also want to learn chess to boost some IQ and keep my brain active besides my work and my piano playing and music composing.
Best and kindest regards in advance. I would love to learn more and, have 1-2 ace's I can use against any amateur I meet, just to gain Some confidence and not be a bad player but don't have to be the best one too. You get it!
Cheers!
