I also play NL 25 and like stated above the players there can be pretty bad, but there are two extremes at this level...

One is a person who will bet large when they have something they think is the nuts, like two pair or TPTK (these are the people who pay off your sets) the other is a person that plays passive till they make a legitimate hand and then tell you plainly that you're beat by betting out rather than check/calling.

Spotting these two types and using this info are the best reads you can make at these levels.

So which type is the villain?
