3 hands from the weekend

Comments on all streets appreciated. :D

HAND 1.

MP is 39/4/1 donk. His range would be TT+, AK and maybe AQ.
Co is 70/53/2.4 and is open raising and c-betting all pp's, sc's, broadways and anything suited. I'm running at 20/12.
I feel like my pre-flop move is just awful as CO's 3 bet size really confused me.

HAND 2.

BB is a 52/18/2 moron who loves to mini raise.
BTN is a weak tight nit 21/0/0.
Pre-flop BB took a long time to 3 bet and it just smelled of a light squeeze. Should I be leading this flop? Check-raising? As played is my turn bet just horrendous?

HAND 3.

MP is 40/15/1 and is just plain bad. He's been playing anything suited but folds a lot without a piece of the flop. Am I smoked here by a boat or trips?

Hand 1- Instacall -- 2 over + nutflush draw w/ lots in the pot.

Hand 2- I think the turn is a check. I am very suspicious of the flush from Ax type hand because of the raise preflop and flop c/c
If he had an overpair the only check would be for a c/r.

Hand 3 - Might be up against a set, but it could be a weaker overpair or a bluff so too much value is lost by folding. Gotta call.

1& 3 - standard.
2 - Maybe you could c/c flop, but I think that might suck. Turn is fucking repulsive though, what do you beat that stacks off apart from the odd bluff? From what I can see you got into the LOL HE'S BLUFFING I KNOW IT mindset, and that loses money.

Thanks for the replies. Although 1&3 seem standard I still hate calling these bets. Hand 1 villain had TT and hit a T on the turn and river came Jh. Hand 3 villain showed 99.

Hand 2 - Ash I think you are right but I just didn't know how to play the turn. In fact I'm still not sure what the best line is in this spot? Villain show AsKd and my TT held up.

Hand 2: Re-raise to $12 pre-flop. Get it all-in on that flop.

ummm hand 1 is a GREAT flop for you, do some poker odds calcs for that hand against villain's ranges
