I have played poker for the last 5 years on/off mostly online, more comfortable in live games are super soft and I find it easy to exploit weaker opponents but currently where I am living there are no casinos. I am crazy passionate about the game and could play a 12+ hour sessions with ease but I have played roughly 1 million hands of poker and I honestly can barely beat PS 2NL, which is crazy to me. There must be something I am fundamentally lacking, something just hasn't clicked, I am missing a certain depth of knowledge and most of my plays are just instinctual rather than calculated.

Has anyone else been in this position? how have you linked the missing pieces and improved?
