i prefer checkraising the flop to calling. it shuts out the middle players, it looks more like a queen (only 1 draw out there), and many observant players (which can include generally bad players) will put you on a deuce, a five, or a pocket pair and subsequently raise the turn when the queen gives them cover. you said your opponent is weak/tight, so it's more difficult to concieve of a situation where he'd call the turn and lose.

operating under the assumption that i had bet the flop:

weak/tight opponent: check/fold. he's unlikely to bet a worse hand if he's truly weak/tight.

loose/aggressive opponent: check/call. getting raised still sucks against them, and you can induce bets from turd hands.

typical semi-loose opponent: bet. they won't bet their 6-outer for you if you check.
