What is the weakest hand what you play check/raise on the flop?

[boowar]

I think it is a big question in poker. It's the strongest move after the UTG limp/raise.
So 2 pairs is enough to check raise against 2 or more opp or should to have a least a straight?

I would say the weakest hand is definitely 7 2 because you cant get a straight off of it

you dont need a top hand to do that,you can/should cr with strong draws,air considering reads on villain.
