Misclicked the Raise button. iPoker 50NL. Villain seemed like the normal boring nothingy semi-TAG who doesn't think much.

Should I have given up on the turn? Is the river a straight fold? I felt he was bluffing the missed FD around 60% of the time, and I felt a minraise would fold all FDs apart from maybe the Td. Plus, I felt a minraise would look like a valueraise to someone who's not thinking and maybe it would fold a weak K or low PP.
