Good day, this will be a lengthy one so any responses will be appreciated.

So I've been playing 1/2 - 2/5 for years, much more 1/2 & 1/3 than 2/5. (What my local casino has) I am now transitioning to Online, I was told to start at 2NL-6Max, play 100K hands, get a coach and I'm about 16K hands in and I don't know if it's just me but I'm currently sitting at -16.39bb/100~ .

First off I want to say I know that this is a small online sample size.

But what I've noticed is people rarely bluff, a portion of my loses are calls I would make at a live game and be right (bluff catching), I'm wondering is this just because it's 2NL or is it because the games are a lot tougher online?

Regardless, my real question for all of this is what would be the top places to study / learn from? I'm going through the essentials stuff (newer stuff, I feel like the old stuff is out dated), I'm also trying to get a better understanding of GTO, I want to be making a serious consistent part time income off online poker like I do live, what would you guys recommend to progress the fastest way?

Also, are programs like Simple Trainer GTO / Poker Snowie worth using or no? I noticed Poker Snowie doesn't even have 2NL.

Direction would be great, I'd even appreciate if someone would go through my 16k hands with me and try to show me how I can analyze it and what i'm doing wrong at this point.
