I've played poker before, 1st learnt to play through some friends out of our group i did the best among us beginners, played a few live tournaments after that an got some real good results. got the bug an went to try learn the game properly online, this fizzled out through work commitments at the time was working very long days. Recently though decided to download a GG poker for a little fun and the bug has hit me again and i want to learn

i know some stuff but have never properly studied and was wondering on my best route

i was thinking

learn some ranges but properly learn them ( i know some of position awareness relative to my ranges but id say i dont know them off by heart)

then i was thinking maybe learn poker maths my odds ev outs and be proficient at doing the sums quick

then iam a little lost id like to gain some good fundamentals to go away and get some few k hands in then look for a course or a coach to push on with the learning, has anyone got a direction of what an where i should be going to start myself off?

also on GG poker i dont think HUDS are aloud but would it still be beneficial to get one so i can go over my own hands?
