I decide to complete with a speculative hand and flop an OESD and a backdoor 8 high flush draw.
I have 6 clean outs and 2 more that would make a flush and a straight for me, so I decide calling getting more than 2 to 1 (30% actually) even though I'm out of position.

I turn the nuts and decide to check/raise. Should I just bet instead? I think that every made hand is betting the turn to protect itself against a flush draw that I might have, and with a low SPR I can check/raise and get it in more often than if I bet.
