2/4 stars - What does this mean?

[Josh.]

either a set or 2 pair building a pot, an overpair or tptk "protecting" his hand if the board is a little scary. in a small pot i don't usually expect to see a draw. i'd usually raise it if i had a big hand, or call with an OESD to the nuts expecting a nice payout. otherwise fold. i think i usually call with a small overpair or TPTK mainly due to a lack of discipline
