well when I have a set, I'm usually checking the flop, hoping to get someone to bet into me. Then I'll put a good bet out there on the turn. And a huge bet on the river. Assuming no one is betting into me. If someone bets into me, I'll check raise on the river.

I think you can tell if someone flopped a set, by how they bet on the turn. If a rag comes on the turn and you get a big bet, he's got a set. I think most people check the flop and bet the turn. They bet the turn in fear of not getting paid for having a set, they check the flop hoping someone bets into them.
