slow playing is absolutely pointless most of the time at low stakes, people who are going to play for stacks will do so on the flop, if you let them check you are just giving them oppertunity to fold on a later street when they havent hit.

At low level, people not stacking off is variance. The donks are there, if you play low stakes and aren't a donk, sooner or later you're going to move up.
