First few hands

First thing i notice is you open limped A9s on the button.
This is usually a no-no unless there was some special reason/read for it.
When opening the pot, especially in late position, but usually everywhere, you should raise.
A9s in 6max is a strong holding to raise even for early position. You don't want to let the blinds see a flop for free and you are going to need to steal blinds. Raise it to 3x preflop.

A8o in the CO, folded to you, you folded. That's pretty tight. I think it's worth a raise there to try and get the blinds.

T6s in BB you flop an FD
A bet on the flop would've been my first impression, but then again those players were really passive so u got to see turn and river for free, so it's fine imo.

A couple of good folds in the blinds (A4o, QJo...)
Those hands may be good enough for defense but the more you avoid playing out of position, the better.

KTo in blind battle
i see you raise to 3x when in SB vs BB. You may wanna raise it to 4x first in from SB so that you get less calls as you will play oop all pots, so you try and get the pot straight up.
U flopped top pair on a T72 rainbow flop. made a pot sized bet. That's ok, I may have bet a bit less, see if he wants to peel light, since that's such a drawless board. Then again it's fine what you did since his calling range wont really change that much.

I'll keep watching now
