Raise preflop like most of said.

Now with the slow play. Here I think is a perfect time to slow play. The board is not draw heavy and are praying for someone to connect with their overcard on the turn.

With that said, I'm raising this about 99% of the time if there is two to the flush on the board or if the board is more connected like 9 10 Q or 9 J Q. You need to fast play your set here and appropriately "charge the draw" as the term is used.
