The problem isn't flop and turn: you should call the flop check-raise and call most turn cards. The pot is big and again the most likely hands you have 6 outs and even if the turn is , you have the backdoor draw to go with. You could have the best hand to begin with, something like 67s/87s in your opponent's range makes sense given the action.

But where it gets difficult is on the river where you will be getting like 9,5:1 on the call and expect to be losing most of the time. I'd probably call the river if turn and river cards didn't complete the flush and weren't middling cards like 6, 7, 8.

Yea I definetly have to call the flop raise for the price, I just realized I dont have much of a plan on these types of flops for the rest of the hand. I'll have to call most turns too because I'll be getting 7.5/1 with 6 outs. Turn was Kc and I check called. River was 2c and I check called, and got shown 4c3c so I might just be results oriented with my questioning my play here. Still a call on the river against a LAG? Spades and other hands in his range that I still beat more than 15% of the time, those would have to fire again?
