Yeah, it is a bit read-dependent to me. If I act last, I will almost always bet if it's three low cards and they've checked to me, representing an overpair or trips. That works well if you've clearly played conservatively. If I'm first to act, I'd usually check. If I'm somewhere in the middle, it really does depend on the reads you have. Are your opponents big bluffers or tight players? Do they fold to bluffs a lot or always come over the top of you? Things like that. If you think you can steal the pot, go for it.
