take the free card. not much he could have been drawing to with that flop. sounds like a pair or a badly played AK. The question is, how high is his pair (maybe he hit the 9 with a holding of A9 or such).

the problem with calling the flop and raising most turn cards is you'll have no idea of where you are at when he fires a bigger volley on turn and what happens if a 2, 3 or some other rag hit turn? not likely villain will believe it helped your hand. If you know the villain will check turn, then yes that might be a good plan to raise turn after a called flop. Sounds like your being results oriented thinking because 10 hit turn (an overcard to the 9 already out there).
