I like to use the idea Harrington put out there in his Cash Game Book...."small hand small pot big hand big pot" which goes to what LuckyChippy states...A set (+) is a big hand so you want to get alot in the pot (bet-raise every time). However, an Overpair or TPTK is not a big hand and therefore you do not want to put too much in the pot (bet the flop and check the turn , or check the flop and bet the turn, the point is, TPTK is not a big hand, and contingent upon board texture, you may be bettinig into a hand that has already beaten your Over pair or TPTK. If you do not have it, I would recommend Harrington's Book on the Cash Game Vol 1 and 2 as well as his on-line 6 man cash book. Good luck in your poker endevors
