7 Hands on villain that raised flop, 29/0, 1 limp

I think my hand is too strong to check/call flop, I'm only losing to 8 combos of KQ and 3 combos of 44. FDs only have 8 outs, SDs only 7 outs. Unlikely villain has K4 or Q4. Villain is most likely fish due to 29/0 and not full stack, so could be spewing.

It's difficult when we've got so few hands on villain, If he's shaping up to be a loose passive fish then I don't think he's raising draws here as he's more likely just to call. It's a concern he's raising in a multiway pot but given his stack size and the lack of information I'm not sure I can find the fold button even though I'm not feeling great about it.

It's a bit gross as I don't put him on a bluff here given the little information we have and the fact that he's playing a pot with fish in it regardless 4 ways, I would put him on the narrow range he reps, I only really see him raising AJs ATs JTs that we beat and we're still not a huge favourite to those.

fold to the raise, it's not even close imo.

fold to the raise. 1- passive player(lol sample) shows aggression 2- We have the Ks blocker which blocks some of his semi bluff range 3-we have to fade a gazillion outs v's draws or we are almost dead v's value hands
