Laying down hands

Well i mean if you hit a pair and still have the 2nd nuts, maybe you are playing weak starting hands? In limit online especially the players are ridiculous, middle is good a lot of the time but no where near all the time. I guess learning to read people online is impossible but like i said, the best players know when to fold, not when to call. Dodging bullets in NL is the big thing, in Limit, not raising when you THING you're beat but arent sure is the big thing, they are such different games...but then again, maybe im completely wrong
