hand 1:
cbet $1.2+ on flop. you're cbet is too small. big hand=big pot.
rest of hand is fine.
hand 2:
pf 3bet is good.
cbet $6+ (but how you played is ok).
when you get minraised on the flop you should push. villain is a donk with 46/16 stats. you don't have that much left anyway and you can't fold on a later street. it is unlikely he has an overpair since he didn't 4bet pf. if he does have an overpair then so be it. he stacks off here with TP too.
as played push turn too. you just have too little left and if he pushes river you're calling anyway (as long as a club doesn't come). it is unlikely that he mincred you with a draw. he could have T9, but you can't fold because there is way too much in the pot.
on the river i think you should call. but you got yourself into a sticky situation because of how you played the rest of the hand. you're getting good PO and only need to win about 28% of the time to make a call profitable. i think you're good enough of the time to call. he could easily be bluffing here.

"maniac raising a lot of bets" - easy call.

hand 3:
i like how you played it.
flop - maybe a $4 cbet is good, but i don't hate the flop check since he is a loose cstation and you have been 3betting light. i think your check is best.
turn - he's bet the turn a lot so you need to call.
river - raise is ok. his bet looks weak. but it's unlikely that he folds a jack here though because he's a donk.
the advantage of raising over calling is that he probably folds low pps and a 9. but you really shouldn't try and bluff a donk. maybe you should just call on the river. you win if he is bluffing and you lose if he has a pp, 9, J or K or QT.

hand 4:
what do you have?
if you have TP good kicker or better, go allin.

hand 5:
go all the way with the hand. he's loose. his VIP is 46!

hand 6:
nb. i probably call the turn cr and call a river bet. if he checks the river then i value bet.
