Playing when a flush comes on the turn

[nflchad]

Its vital to bet the turn here, otherwise you'll have no idea where your at and could be giving free cards. So I would fire $9 (1/2 pot) on the turn, if you get raised though it's time to muck the hand. If you get called then check on the river, I would then fold to anything over $20 (close to 1/2 the pot) and call anything under.
