I have a doubt, I play full ring NL cash, and usually I just limp with pairs like 55, but I have read some people saying that you should alway raise a pair if want to play them. I just limp because I think that if I encounter a bigger pair and a reraise, the amount of money that I will put to see my set is less. If I just limp and someone raises me I know he has bigger pair or cards and I pay with implied odds to see my set. What do you think about that?
