Couple of questions to help us get an answer, if you can remember:
- who was the preflop raiser?
- how many players at the table?
- what are the stacks of the players who checked?
These are just a few things that should dictate how you would act here. If you are the preflop raiser, it's a close call-- I would probably make a continuation bet because generally it seems less suspicious than checking. Since the pot is multi-way and not heads-up, however, you may receive more credit for a hand from your opponents. In a vacuum, I would still bet out here.
If the player left to act here was the initial raiser, it's still a close call between checking and betting. Checking would be best if you believe the villain will make a c-bet. As in the previous situation though, since we are in a multi-way pot, he/ she may be less likely to c-bet, so it may be better to lead out ourselves. On average, I think I'd check, planning to raise a bet from the villain-- depending on the villain's stack size, and the action's of the players to act before me.
As you can see, it's dependent on a lot of information that isn't available to me :-\ Hopefully in the future, you can take notes or something in order to get a better analysis.
Good luck!
