I am starting out at the micro level and am wondering which theory and skills you would recommend for which buy in level, the reason i ask is it is easy to become overwhelmed by the amount of topics available and end up doing a little of this then a little of that and not gaining the full understanding of what is being taught.

I was going over some videos working on ranging and hand reading then realised in the last tournie i played these happened –

MP raise, LP reraise, cut off flats with the MP still to act, am i putting the flatter on A-7 offsuit

UTG 3x next player flats, am i putting the flatter on 2-5 hearts

EP 5x raise called LP, am i putting the caller on Q-4 of clubs

You see my point, hand raging can't really exist at this level so what skills would be considered the most relevant for this level, it would be great if we could come up with some kind of recommended skills such as,

Buy in level 1-5 – skills most relevant are ______

Buy in level 5-10 skills most relevant are ______

Hope this isn't a dumb question it's just i plan to be in this for the long haul so i want to try and build solid foundations at each level as i hopefully move up.

Thanks
