Foray into 100NL

How are my lines? Don't have much for reads since I am just stepping into the 100NL areana.

hand 1

Villain had 3bet me preflop once (SB vs his BB), and I check-folded on a AJx board. How are my bet sizes? When he called the turn I figured he had a hand like AcJx or maybe 2 pair and wanted to get a little value. If he pushed I'm not sure what I would have done, probably folded.

Hand 2

Villain was running 18/15/3.33, stealing very often and rarely going to showdown. I did see him make a weird minimum raise with KJ (no hearts) on an 89TA(3 heart) board against a preflop raisor though.

hand 3

Villain running 16/14/4.71. His extra large turn bet seemed weak to me, so I let my time run down and pushed into him.

Hand 4

Villain running 21/7/7.00 and hasn't done too much that's memorable. His minimum 4bet preflop was made instantly. His flop bet was super weak, but I didn't want to chase away hands like 99-JJ / AK that will liekly keep betting. When (if at all) should I let this go? His turn bet made it seem like he was very eager to play for stacks...

Hand 1 is good
Hand 2 is standard
Hand 3 meh, why even play the 23s OOP. I just muck this PF but I play pretty passivly SB vs BB. I think you played it fine though
Hand 4 It's though but I think you can fold river.

hand1: looks good
hand2: check that flop, you are usually called here. The reason we check/F is this is a 3bet pot and WTF do you think he has here that might have missed? I guess he could have a small PP, but most of the time he shows up hitting here
hand3: muck from sb.
Hand4: That small 4bet screams AA or KK to me. My plan is to call for set value, and bet an A high flop as he could have KK. I don't see much fancy 4betting at 100nl, mostly vanilla KK/AA

hand 1: nice

hand 2: 3-bet bigger to $18 or so, especially since you are in the blinds. Your flop bet screams weakness, so either check or bet bigger. Obv shut down if called.

hand 3: fold pre. its spewtastic as played.

hand 4: gross. idk, i suppose you should fold somewhere, im just not sure where.
