I c/r flop, fold to a raise. Why is he betting less than half pot with draws on the board? If called, probably check turn without a post-flop read, but sometimes lead. Another line is call flop, lead turn, fold to a raise, or if you're feeling really ballsy, c/r turn (but I like that least, without a read). There are a lot of weak/tight players at FT 100NL FR, in case you haven't noticed yet. Find them and be a bully.
