5nl hand v loose passive fish

[EasyPoker]

NB - ignore passive in the title

Villain is 65/21/31 (agg%) over 111 hands. He hasn't folded to a 3 bet in 4 opportunities.

I have some reads on him, but not stored on HEM. His stats tell a story anyway.

Here I'm seeking advice more on whether I got his range right

PokerStars No-Limit Hold'em, $0.05 BB (6 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

Hero (MP) ($5.03)
CO ($5)
Button ($5)
SB ($5)
BB ($13.07)
UTG ($14.88)

Preflop: Hero is MP with ,
UTG bets $0.15, Hero raises to $0.60, 4 folds, UTG calls $0.45

After 3betting, I put him on having seen what he's come up with before at showdown:
66+,A8s+,K9s+,Q9s+,J9s+,T9s,AQo+,KQo

Flop: ($1.27) , , (2 players)
UTG checks, Hero checks

We both check so I narrow range to

88,ATs+,A8s,KTs+,QTs+,JTs,AQo+,KQo

Since he was passive on the flop by checking, maybe I shouldn't have ruled out the fact that he could be slowplaiying sets/stronger hands...that said, I just don't think he wouldn't have bet sets on the flop

Turn: ($1.27) (2 players)
UTG bets $0.50, Hero calls $0.50

I think he continues with

the same range but also think he could be slowplaying a set or be on a straight draw, or just bluffing. I veer towards the latter two since I removed sets from his range after the flop.

88,ATs+,A8s,KTs+,QTs+,JTs,AQo+,KQo


River: ($2.27) (2 players)
UTG bets $0.50, Hero calls $0.50

I put him on the same range as before or air. I call because I'm convinced he was bluffing, although based on the bet size I probably should have folded.

Total pot: $3.27 | Rake: $0.15
