Hi guys^^ lately I found myself in this hand of nl100 6max
Me BB 100$ , UTG 74$ occasional player, Cut off 143$ a Tag reg.
I'm in the BB with 3s3h, utg limps and cut off raises to 4$, I call and utg calls .
Flop comes 3c 5h 7s rainbow, I check (should I donk bet here??), utg checks, CO bets 8,5$ and call to let utg call as well so he does!
Turn is an 8s, I check, utg bets 15$, CO raises to 39$! 
So 87x deep should I call/push/fold???Any decision seems legit to me after this action!
Thanks every1!

6 Max Table PLO400, 4 players at the table.
Stakes are SB 407$, BB 673$, UTG 400$, Hero (btn) 1906$.

Utg fold, I open 10$ from the btn with AcJhTh5d, SB 3bet 34$ and I flat ( he 3bets 20% of hands). So Pot is 72$
Flop is As5sTc and he cbet 56$ and I call, Pot is now 184$.
Turn is 5c and oppo checks here! 

So should i now check behind to pot control? Bet and how playing if he raise? Thanks for help guys^^

Hello everybody I'm still thinking about a hand i recently played.
I'm  at NL100 6max table with 100$ 
I'm in the cut off with Ac6c and open raise 3$, just the BB calls.
Flop comes 7c 8s 9d. Oppo checks I cbet  4$ he calls.
Turn 2h, he checks, I overbet for 17$ and he calls again.
River an A comes. 
So I didn't really know how to play that.
What's the best action with a random oppo??Help please :)
