More hands, good & bad (I think...)

750 hand $10NL session. Ran 19/7/5.2. Ended up down $5... mostly from two AI calls against the same villain. The first one was stupid. This was the second one...

Hand#1:
Villain had about 20VPIP

Flop: Q 2 3 ($2.9, 4 players)
SB bets $2.9, Hero calls, 2 folds.
Got my shiny TPTK. See this bet as an attempt to push out flush draw. Put villain on KQ,JJ,TT,99 - maybe 22 or 33 but I'm trying to give up seeing sets everywhere when there's aggression...

Turn: 9 ($8.7, 2 players)
SB is all-in $6.04, Hero calls.
I don't see how a 9 changes much relative to the flop. I call. Should I have assumed a two-pair or a set based on this push?

River: K ($20.78, 1 player + 1 all-in - Main pot: $20.78)


Results:
Final pot: $20.78

Hand #2:
I'm happy with myself on this one.

BB: $5

Pre-flop: (10 players) Hero is UTG with Q A
Hero raises to $0.2, 3 folds, MP2 calls, MP3 folds, CO calls, 2 folds, BB calls.
The raise was a misclick. Mean to raise to .40 but slipped...

Flop: J K 9 ($0.85, 4 players)
BB checks, Hero bets $0.5, MP2 calls, CO calls, BB folds.
Part cbet, but also like the SD, possible flush and still TPGK potential. So I bet 1/2 pot.

Turn: 8 ($2.35, 3 players)
Hero bets $1.2, MP2 folds, CO calls.
Now have the nut 4 flush, plus still the SD & TPGK. Going to lead out like I mean it again.

River: 5 ($4.75, 2 players)
Hero bets $3, CO folds.
Uncalled bets: $3 returned to Hero.
Old me would have folded this. New figured a) I got a sh!t load in the pot, b) I've bet consistently through the streets so villain should assume I have something, c) he's going to expect me to check with a busted draw and d) he's shown no aggression. So put a real bet in and it worked!

But seriously... was this too loose? I'm not real comfortable leading OOP w/ air...

Results:
Final pot: $4.75

Hand #3:
Only thing I can think here is pot-size bet on the turn? Plus should I have read his River min-raise as having the made flush?

Thanks in advance!

hand 1 you should definitely raise the flop, most likely a push.

hand 3 I don't get. You went for a check-raise, but then didn't make it nearly big enough, especially with the caller between you and the bettor. I don't know that I like a check-raise on this board with TP Q kicker, but if you are going to do it, raise more.
The turn needs a bigger bet as well. Less than 1/2 pot with 2 opps, a flush draw and a straight draws out is just bad. Especially if you intend to put more in on the river.
FWIW I usually pay off the min raise on the river.

Hand 1: TPTK is a tricky hand to play, albeit from my experience. See it as a hand with very litle chance of improving (unless turn/river pairs your TP or your TK). Try not to bet a lot of monies everytime you have TPTK, specially against such a dangerous board.

Hand 2: NH. Welcome to NL.

Hand 3: Depending on reads, like {Villains plays any two soooooooted}, I may check/call a tiny bet, no more.
Better play would be to 3~4x his bet on turn.

Also, try raising QJs from time to time pf. TP is very dangerous in family pots.
