Reading between the lines, you are asking about playing suited aces-rag.
My advice / opinion is as follows:
Early in a tournament - try to limp in with no raises and hit a big hand.
Late in a tournament - throw them away, the blinds are too high for you to make this play .
If it's folded to you in late position in a tournament, you can raise with it, but it's a risky play for obvious reasons.
In low limit cash games, try to limp in and win a big pot.
You never want to play these hands to a raise. The chances of you flopping your flush or getting a flush draw and being given odds
to chase it are small. It's never a good idea to get all of your chips in chasing a flush. "People who chase flushes go home in busses", lol.
Hope that helps.
