I agree with Fnord and Lukie. Betting this turn is horrible. If you do bet 1/2 pot, you are betting $16 and villian has $12 left behind. So if he CR's AI, you have to call $12 into a $64 pot, just an ugly situation to be in. Check behind and hope to fill up and stack him. Otherwise call a small bet.

If you just call the $7 on the river, you are paying $7 instead of AT LEAST $16 to get to the same showdown. Which one sounds better?
