Like I said before, you will make mistakes. You will run into trouble. Poker is not an easy game and in my experience in today's games, it's the guys who put in the effort to actually get better who will be winners eventually. You'll have to get the math down. You'll have to make your own calculations on your own hands. Don't expect to get spoonfed by someone and that that is gonna make you actually a better player.
My advice for any "set ranges" player would be to keep playing your set ranges for now from all positions BUT the button. That way you assure yourself of one key thing each and every time you're in there with some "junk": POSITION!
Marginal spots aren't as easy to play as is valuetowning top set vs a calling station. So having position is key when you don't have too much experience. Position will be key later also when you start widening your ranges from other positions if the situation warrants it, but as you progress you will get better at assessing your chances of ending up in position. Even if you don't end up heads up in position (HULA as Tommy Angelo calls it) you will have the nessecary experience to play these spots.
Work on your handreading. Have a reason for EVERYTHING you do at the table. When you bet, think about if you want to get better to fold or worse to call. Then think about WHAT better hands could fold and WHAT worse hands could call. Then think about which one of these hands are actually possible for villain to have in that spot... etc
Question EVERYTHING you read about poker. Start with this thread. Don't assume that just because someone posts something on a forum he therefor must be right. It is absolutely imperative that you think for yourself about your game. No forum post, training video or even coach can do that for you.
If you do all that....
... you'll still **** up at first
You can't learn if you don't make mistakes but the more mistakes you make, recognize and then eliminate from your game, the better you're gonna get and the higher your winrate is gonna be.
One final note about variance. Don't be fooled by that term. EVERYTHING in poker is variance. In fact everything in probability is variance. If you flip a coin with a buddy for $1 your EV for each flip is gonna be $0.50. Yet in each flip you either lose or win $1. You will NEVER get your exact expected value out of a bet unless you put the money in with 100% equity.
The reason why people are afraid to play a "high variance" game is because their winrates are usually small. Hence they play a "low variance" game which isn't exploiting every available edge. Hence their winrates are gonna remain small. Hence big suckouts hurt even more. Hence their "low variance" game is actually a "very high variance" game as compared to a style that tries to exploit thinner edges all the time.
Think about it:
Say you're a 5 ptbb/100 winner so after 10,000 hands you've made exactly 10 buy ins. Now you get in AA vs KK 200BB deep and the guy flops a K on you. Now your profit is only 8 buy ins and your winrate
decreased by 20% down to 4 ptbb/100 due to "variance"
Now say a 2 ptbb/100 winner (up 4 buy ins after 10,00 hands) suffers the very same thing. His winrate now
decreased by 50% (2 buy ins up after 10,000 hands or 1 ptbb/100)
That's a 30% difference in decrease of winrate that the "low variance" player suffers due to the very same suckout.
Wow, long post again.
Hope it helps.
