Villain is 34/9 over 28 hands and limp calls a bunch preflop.

I raised the flop to get value from draws and lesser over pairs, but didn't actually decide prior to doing this whetehr it was actually good idea to stack off.

I then decided he could do this with all his flush draws for sure and possibly some terribly played 99 TT JJ. It's probably a fold though because smalls pairs that have sets here are very much in his range aswell as some stright combos and even the draws I'm ahead of, I don't have great equity vs.

Can we just raise/fold this flop since this guy looks passive and unlikely to ship draws too often?
