Much of the value of raising those hands I mentioned is picking up blinds and eventual loose limpers, which adds up in 6-max.

Raising AT and winning the blinds/limps is a good result, raising AA/KK/QQ/JJ/AK and picking up the blinds is alright but you would have preferred to get some action.

Remember when you raise a marginal hand pre flop you don't have to make a continuation bet when you miss, only do so when you think that you have the right odds for it to be a winning move. Be honest about it!
