I had these situations come up yesterday in a no-limit tourney style home game, and realzied I am not entirely sure the best way to play it.

I am SB. Its the second hand of the game blinds are 10/20 ( started with 2500). I am delt 79o and I complete into an unraised pot. The flop is 6 8 K rainbow. I have an OESD, but now I am first to act.

The next time the BB gets to me (blinds still the same) I get K9s. I check an unrasied pot. Flop come As 3s 7h. So I have the nut flush draw. The SB did not complete, so again I am first to act.

What do you guys do in these situations?

(Note: Even though this happened in a tournament, I posted it here because I figured it would apply to ring games as well)
