In my experience, beginners don't fold or raise enough.

In beginner hands, you will have to showdown the best hand to win. Make sure the pots they drag in are smaller than the pots you drag in.

Pretty straightforward I think. Just don't try anything fancy. Beginners don't recognize things like check-raises as indications of a monster hand, so it's usually best not to try tactics on them like that, unless they tend to bet trash alot, as opposed to simply calling.
