I believe that it depends on your position at the table. If you're early position, a fold, or maybe a call is best. Hoping for a great hand by the set, though someone may raise you thats in mid to late position, and your could lose chips. In middle position, I recommend a call, as your waiting to see if you get trips, but you shouldn't raise as their could stuill be better preflop hand then you. In late position or are SB or BB, however, you probably should call (when its just BB), so you probably get the easy 3 cards. Though, you could raise (when folded to you or only one caller), to try to win the pot preflop-when considering to do this, you have to consider if your stack permits this, so you do not have a significant decrease of chips as a result of doing the raise.
Well, that's preflop (your first action the hand). If you hit the trips, most likely depending on the aggression of your table, you may want to make the bets (you can get amounts you want, though opponents may fold, fearing you have a better hand. Or, you may want to slowroll (taking lots of time on decisions *check,call,bet* to make them think you have a poor hand. Though, the hand could end in a dry pot.
