Where to go from here...

Tldr: Not exactly a beginner player, but complete beginner in the more tactical/stragy side of chess. Recommendations that won't make me not interested because they are too simple but would be a good place to start. Hey everyone, my name's Muamer, and this is my first post here! I stopped playing after highschool because I had no one who wanted to in person, and I sucked online because I never could visualize the board. I always had to have one next to me and it was a hassle. I just started playing after Three years again, inspired by a square off board, since I and I think I want to take it to the next level this time around. I played chess for a couple of years in highschool/middles school, but never took it too seriously. Just learned by playing and got pretty okay at it. In highschool I hung out at the chess club (team/club met together) but never played on the team due to lack of transportation. that being said I never studied openings, endgame or anything really. I just learned that the opening I have enjoyed using on white for years is called the queens gambit, that's how uneducated I am in the terminology more indepth things about chess. that being said in highschool I traded blows with 14-1700 rated players and my chess.com account landed around 14-1500. so this kinda where my predicament starts. like I want to learn more, but at the same time I don't want to start at the very very bottom of knowledge because I know I'll get discouraged if I'm like, oh I know all of this. So I am looking forward to seeing what you guys have as recommendations. books, videos, or whatever else! Also, I've been playing 30 min games online, currently around 1350, because the only way I can win is if I really stare at the board, and if I'm usually awake my accuracy is around 85%. But my blitz rating is bad, and my accuracy is around 60%. Any advice on how to visualize the board better in short 3|2 games? hope to hear from you guys! thanks ahead of time (:

play more slow games like g/30. it will help you visualize in any time control really. most of what you calculate in 3/2 will be short as far as i am concerned so not much visualization here. tactical alertness and intuition, resourcefulness. those are more important and i don't think you can get them by playing more 3/2 games. they have to be built upon by experience and training.
