If you are playing pretty tight your range should be a lot of value, so why is getting raised necessarily a bad thing?  

In determining when to cbet you have to think about a lot of differnt things, whats their range, whats my range(imporntant in sucessful bluffs and getting max value), what am I repping, what is my future plans(if I am bluffing flop, will I have a lot of good runouts that make my bluff more effective? You cant go from repping a strong pair to repping a flush, etc.), but most improtnatly imo, is what are my reads on villain, and what are his likely perceptions of me.  Once you consider all of these you should be able to get an answer on whetehr to bet or cehck your value or bluffs dpening on board and table flow.  its ahrd to give a genreic answer to this Question though.

In general when trying to take down pots you missed with a cbet you should be focusing on betting off fit or fold players and betting flops that hit your rnage more than theirs(high cards when opponent is BB for example)
