Okey well you are playing tight and the might have noticed that, but the CO has position and you raised from MP2 so his range could contain a hand like QTs (to really establish that ain't so, we have to get some numbers). On the flop the idea of letting them know you are not trying to take a cheap stab is scared poker in a sense, because apparently you are afraid that they are going to trick you with a weaker hand if bet less??? I don't think your opponents behaviour will change a lot with the few cents more or less you bet into the pot, but it definitely can let the pot grow larger when you are WA/WB. I would bet around 1,10, which could just maybe induce him to stick around with a gutter or a middlepair. On the turn I would take a bet/fold line as explained already.
