In general it depends. Not really a great answer, huh.
What does it depend on?
Tourney or cash?
If tourney, ITM, on the bubble, just started?
What's your opponent like?
How often does he cbet the flop? Turn?
What's your image like?
How much $$ went in preflop?
How likely is your opponent to bet the turn with worse?
How likely is your opponent to call if you raise?
Anyone else left to act?
Probably a few other things I'm forgetting atm.
So you see there is no answer to your question because it's too general. Posting a few hands you have qusetions about will help you 10000 times more than this thread.
Here is an example of a recent hand I played.
CO is a 17/9/3 type who cbets 100% over 155 hands.
BB is a horrible 91/0/.5 over a short 30 hands.

MP2: $56.15 (112.3 bb)
MP3: $103.90 (207.8 bb)
CO: $57.55 (115.1 bb)
Hero (BTN): $50 (100 bb)
SB: $105.95 (211.9 bb)
BB: $142.55 (285.1 bb)
MP1: $43.25 (86.5 bb)
: Hero is BTN with Q
3 folds, CO raises to $1.75
, Hero calls $1.75, SB folds, BB calls $1.25
: ($5.50) 4[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/spade.gif] A[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/diamond.gif] Q[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/heart.gif] (3 players)
BB checks, CO bets $3
, Hero calls $3, BB folds
: ($11.50) 7[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/spade.gif] (2 players)
CO checks, Hero bets $6.50
, CO folds
$11.50 pot ($0.55 rake)
Hero mucked Q[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/club.gif] J[image: http://www.stoxpoker.com/hand_history_converter/images/emoticons/club.gif] (a pair of Queens) and won $10.95 ($6.20 net)
So in this hand I call the cbet with middle pair because the BB is never bluff raising and the CO is unlikely to bet the turn without an Ace. As always being in position makes my hand so much easier to play.
Now you post a hand where you floated a flop.
