Villain is 24/20 winning reg. 27% VPIP UTG, 53% CB in position. I mix up sets on the flop here by sometimes check/calling and sometimes checkraising. The nut worst card turns and I have no idea how else to play my hand other than the way I did however I literally don't have any hands in my range that would check/call turn and river all in so I'm at the top of my range. Should I be calling this hand trying to pick off pairs that are turned into bluffs?

Hand2:
SB: $410.96 (102.7 bb)
BB: $502.67 (125.7 bb)
UTG: $725.98 (181.5 bb)

Preflop: Hero is CO with Kc Ah
UTG calls $4, MP folds, Hero raises to $16, 2 folds, BB raises to $54, UTG folds, Hero calls $38

Flop: ($114) 9h Kh Qh (2 players)

BB bets $118, Hero calls $118

River: ($472) 4d (2 players)
BB bets $269.67 and is all-in, Hero folds

UTG is a reg and villain is an ok reg playing 25/19 with a 10% 3bet BBvsCO. I haven't noticed him over-3betting isolation raises at all and normally get it in PF in this spot but villain seems super cally postflop in 3bet pots and I don't think he has a super wide range to get it in PF here. Flop and turn seem standard and besides getting 4:1 on the river ($167 effective), I'm having trouble seeing what I beat besides a suicide bluff. I think the river call is easy if I don't have the Ah, should I be calling hoping for the split/a suicide bluff given the river odds?

Hand 3:
SB: $254.14 (63.5 bb)
Hero (BB): $724.90 (181.2 bb)
UTG: $439.26 (109.8 bb)
MP: $400 (100 bb)
CO: $594.94 (148.7 bb)
BTN: $538.12 (134.5 bb)

Preflop: Hero is BB with Qh Qd
2 folds, CO raises to $10, BTN raises to $32, SB folds, Hero calls $28, CO calls $22

Flop: ($98) 2c 3s 2h (3 players)
Hero checks, CO checks, BTN bets $60, Hero calls $60, CO folds

Turn: ($218) As (2 players)
Hero checks, BTN bets $116, Hero folds

CO is a fairly unknown decent player and BUT is a reg playing 23/18 with a 7% 3bet on the button. I normally 4bet QQ in this spot and am quite happy about it but chose not to due to villain's low 3bet%. His flop cbet% is 39% so it seems he has AA-JJ and maybe TT when betting 3way on the flop. The turn isn't a blank but I still might have just check/folded a blank turn against this player given his low 3bet% and cbet%.

Thoughts on any/all hands are much appreciated. Am I allowing myself to get run over or am I making hard but decent folds?
