a few hands from 400NL

Villain in this hand is Jamie217. He's a straightforward TAGG who 3-bets a little light but i've really never seen him bluff. What should i do on the turn, is it too weak to just fold? Also flop and preflop comments are welcome.

Villain in this hand is a semi loose, very aggessive reg named FoolMeTwice. I've seen him float in position a few times, he's definitely willing to bet with air or with a marginal draw. He seems like he's a pretty good player.

I'm pretty sure this is good i'm just checking.

Thank you.

1. I never call pre-flop. Drawing hands oop suck, esp one this crappy. As played I c/f flop. Turn is weird, what the hell does UTG have? I think he might have a set... not much else makes sense. c/c I think and bet/fold blank river.

2. I c-bet bigger in general, like $35. I prefer a second barrel, fold to raise, but I don't hate this if he can fold an ace.

3. Bet river smaller, like $140-ish, definitely fold to raise. Even as played. He's never raising without a queen imo.

sorta off topic... but what does "three bets too light mean" - lighter than you?

1) No like T7s OOP. I think UTG has AK. Board is dry so no need to worry about charging you guys. Turn is a heart and he decides he better not give a free card. Could also be a set or KT. What about AJ/AQ hearts? He floats with an over, gutshot, bd flush. On turn he has maybe 16 outs - time to find if anyone's serious.

If either of them stacks off lightly I think I look to get it in with 2P when only a better 2p or set beats you. If they are more weak tight then a min/raise looks good. But I'm not folding unless I really think someone has a set or third heart falls.

Hand 2: I give up after c-bet is called. He probably has an ace or club draw or both. Bad board to bluff on.

Hand 3: 20-20 hindsight, but maybe check river (and probably call). As played, I guess you have to call getting like 8:1...although you only beat a worse 2 pair.

1. fold pf like people have said, as played i have no idea wtf jamie217 has, that guy is a pretty big nit, and whatever he has he played it weirdly/stupidly. My best guess would be KK, but that's no more than 15%. I definetely raise the turn and call push.

2. Your flop cbet is really bad. I like a two barrel here, a c/r just seems kinda weird. Idk, I definetely don't like giving up on the turn on this board.

3. Bet/fold river.
