A very common situation; advice?

[JJNJustin]

You raise or reraise an early position player or limper with a decent pocket pair (99-KK), get a call out of the big blind as well as the epp, and flop contains exactly 1 overcard. Either the blind or the epp bets into you on the flop, and there may or may not be a flush draw.

What is the correct play?

For example, an epp limps and you raise with JJ, the big blind calls and the epp calls. The flop comes A92. The epp bets into you. What is correct long term strategic play?

Here is another example. A player UTG raises and you reraise with QQ and only the UTG calls. The flop comes K96 and he leads into you. What is the correct play?

Any answers would be most appreciated.
