I think the turn continuation bet, in the spot where nobody has bet the flop and you are in middle position, is a strong move and has a high success rate in stealing pots. Clearly, I think it has to be made with the right circumstances, with only two or three people in the pot, the board texture has to be right, and they have to respect your bet. If you're in MP, the bet is more likely to be uncalled since opponents won't put you on a steal, where if your'e in LP then they might consider calling with ace high or something because they feel you're trying to pick the pot up. Note that the preflop action is important too... if it's an unraised pot, then it's probably going to work more, depending on the table.
