Raising with good hands builds the pot.Do not give people a free chance to improve and beat your strong hands. For example, if you limp with AA and your opponent in the big blind checks behind he will have a chance to outdraw you to three of a kind or two-pair. You give the other players a chance to beat you with their weak holdings.Good winning players very rarely limp and there are many reasons why:
Often, new players limp to see a cheap flop with speculative hands or to trap with strong hands such as AA or KK.
