So I played Valorant a fair bit when it first came out for about a month or two and managed to peak Plat. Upon returning I feel like an idiot in most of my games and need some clarity about the movement as I am trying to learn but don't know what I should be learning.

I have watched a fair few videos about movement but have come out confused. Some say to learn counter-strafing whereas others say that its redundant? I hear the term deadzoning and jiggling thrown around a bit as well but am not sure if there's a difference or not. I'm trying to run deathmatches to learn 'counterstrafing' but find it frustrating as I feel like I'm not even learning the right things. Am I supposed to be pressing the opposite move-key to stop faster or is simply releasing the key better?

I'm just overwhelmed with what to learn as I'm trying to fast-track improvement and need some clarity so I'm not wasting time on the wrong things.
