First of all, I'm sorry if it looks like I didn't really research before asking the question, but I really did put in some effort and couldn't find a satisfying answer.
My problem is, I don't want to spend a lot of time studying openings. I don't really like the early game that much, I really just prefer to get it over with. I don't want to waste time learning a lot of theory by heart, as I'm relatively new, and I believe the biggest improvment will come from actually playing the game and not memorizing moves. Another problem is, when I'm trying to "just play", react to what the enemy does without going by any theory, I usually end up wasting tons of time against someone who knows what they're doing in their opening.
So, the question is - what are some easy, "quick-start" openings which don't require you to learn 12 different variations, which are relatively safe and prevent some early game cheese tactics that would confuse a begginer? Is there such a thing? I'm interested in both white and black openings.
Currently I am spamming the King's Indian Defense in 99% of my games, and I do enjoy it, however I'd just like to try something different, maybe something that fights for the centre a little bit more in the beggining?
They don't necesarily have to be setup openings (as in, an opening that's almost independent of what the oponent does), maybe a theory based opening that's pretty "universal" or, well, "easy" to learn?
