Final Pot: t4625

Flop: Against these passives, I thought a check might give me more information than a cbet and also keeps the pot small. But of course, it's a nice flop for a cbet and if being ahead, a freecard to an A,K or J is ugly. Your line?

Turn &amp; River: Thought they were valuebets with someone hanging around with a lower PP like 77-99. O.K., so?
