Well, I'd make a general descision here: Fold or raise.
If I decide to play ATs in early position (UTG,UTG+1,UTG+2) not knowing my opponents, I'd go for a raise to get a feel for the table, to be able to narrow down the range of hands I will be facing, and to pretend holding AKs+. However, I'd bear in mind that if someone reraises me pre- or postflop that I am probably beat. Especially in a full ring game it is likely that you run into a better ace if someone shows strength. So, you must aim for two pair or a flush (draw) on the flop. If you miss, fold to pressure, because you might be dominated by a bigger ace (if the ace hits).

Personally, I would only limp with these aces in early position if I am facing weak/tight or loose/passive players, who will let me see the flop for cheap and if there's a lot of limping pre-flop.
If I do not feel that I have an edge, I'd rather fold both A9s and ATs in early position, because it is likely (depending on the players and their aggressiveness) that I run into a re-raise coming from AA-JJ, AKs-AQs.

Sklansky and Miller suggest in their book to usually open-limp with suited cards J+ (e.g. KJs, AQs) and any AXs, and to usually open-raise with AA-QQ, and AKs UTG.

Also, just because they r suited doesn't make these aces UTG-raising hands. Generally spoken, A9 and AT are just aces-high with a mediocre kicker. I wouldn't want to face pressure from middle position or the blinds with these hands (being out-of-position post-flop!!!).

That's my opinion. Yet, I am still an apprentice, so feel free to disagree. [img]/images/graemlins/grin.gif[/img]
