Slowing down with a boat??

We can't really give any decent advice if you don't post the stack sizes and bet sizes. Also the amount of limpers, his position and whether there was a flush draw on the flop would be nice.

However, you can't go far wrong by betting out or check raising the flop. If you check raise him here, considering the general calibre of PP players, he's likely to commit with any two pair, overpair or top pair.
