Made Flush - Limp Reraise - Can I fold?

[PokrLikeItsProse]

For those who say this is an insta-call, you are guilty of first-level thinking, where you are looking solely at your cards and say, "ZOMG!!! I have a flush!!!!" While I wouldn't fold, I think that the OP is correct to take a step back and re-evaluate his hand based on the action in front of him, including the response to his raise.

I think that the correct answer is to raise so that UTG puts his last 50 chips in with what I think is a set of aces or kings and put SB all-in with what I guess is two pair or one pair with a high club...possibly a set that tried and failed to check-raise.
