This is the part I'm wondering about. I certainly am not folding a Straight Flush, but leading and getting raised is not an attractive outcome here. Is this a wise check/call situation? Even if he pushes, I'm calling so is it better to value bet?

OP2's flat cold-call on the turn made BIIIIG sirens go off in my head. Finding out if the Qs was out there was the reason I raised there to begin with.

I felt gross afterwards. Not only wallowing in my weak-tightness, but like I somehow managed to get out of Bubba's cell without getting raped.
