LO8: Raise or limp UTG with premium hands???

[Zophar]

That's basically the point of what the others are saying, understand the table dynamics.

If you are UTG and it's LAG after you, limp/reaising is suitable. If it's not LAG after you, limping is probably the best bet. The key is getting action.

If in situations like you describe, open raising my be fine if you are going to get the callers. I've played many tables where a raise is meaningless for isolating and it's strictly used to build pots because the opponents will call 1 bet or 2 without any hesitency. Let the play of the table dictate your optimum approach to the game.
