150/300 TP, coordinated board, vs neverwin

[kurosh]

This is from a while ago. I don't remember any reads. Neverwin is CO and SB is nojob on UB.

Neverwin opens CO, nojob calls in SB, I call with Q8o in the BB.

Flop QJ9r
SB checks, I bet, CO calls, SB raises, I call, CO calls.

Turn 5, putting out a flush draw.
SB bets, I call?, CO calls.

River 5, SB checks, I bet, CO raises!, SB folds, I call?


Turn I probably should've raised to get CO out, but I'm not sure since I can't fold to a 3-bet. Maybe then a flop 3-bet is best? On the river, I couldn't put him on a hand.
