In small/micro stakes, C betting after you raised pre flop is normal. It often allows you to take down the pot, and when you get check raised, they usually have you dominated.
Players at low stakes are straight forward. You should be able to classify them into a category within a few rounds. This is when you can take advantage post flop.
If they are aggressive, you can check back your best
hands and let them start throwing in chips. If they are calling stations, only Cbet hand that hit your hand. If they are nits, Cbet and slow down if they call.
Before you play, think of what you want them to do. What play by you leads to the other player doing what you want?
