Hi, I'm a 100z player. Been playing poker seriously for almost a year now. When it comes to study, i'm so lost and have no direction at all.

I have never done any solver work before.. my studying tools are basically just runitonce essential vids, kanu cg course..

Can anyone give me some advice? should i start off reading some books about poker theory like application of nlhe? (since some old threads suggested it strongly, don't know if it's still valid today) Or should i devote my time to solver and run sims and learn this way?
