I call and see what the turn brings, prolly fold to further action.

Just sat down.
If I check turn and river after calling, he doesn't have to bluff much to force a poor decision. I was thinking I was up against a flush draw bluff raise (unlikely given action), 79, 8T, J9, and I'm losing to 2 out of three of those, and it will probably cost my stack to find out. Not sure if thats super passive.
