I think I have some advice to offer concerning the nit/low variance style.
Play really tight, and use position wisely. I don't really understand stats all that well, but I have a VPIP of around 20-21% on 6-max. That is what I mean by tight.
Stop limping your SB (I don't know if you do). If you don't have something good, fold the SB.
Don't c-bet
bluff into more than 2 opponents, and don't c-bet bluff wet boards unless HU (even then, yuck).
Don't triple barrel into sticky opponents on dry-ish boards.
Give opponents credit when they show aggression on turn and river (in micro-stakes anyways). Don't call down "hoping" your hand is good. If you have that bad feeling, listen to it.
Don't bluff stations.
Semi bluff less in 3-way and multi-way pots.
Stay away from K-Jo, K-Qo, Q-Jo OOP. Those are some of the biggest trouble
hands that everyone plays. If you want to play them, do it with position. Even then, be careful. Suited versions of these hand play much better.
These are just some suggestions. Understand there are no absolutes in poker, like "never" or "always". Every spot is different. Dynamics change things.
I am just offering some tips that I feel have helped my game.
Edit: I only considered this now. I play on Bovada where it is anonymous, and Zone also. There are no reads. So my carefully worded post probably doesn't apply to you anyways. It might be exploitable in your game. I really do mean well though....
