Back To Basics. Annoyingly simple preflop question.

[Grisgra]

After the 100BB downswing I just had the last two days (mostly from 30/60 and 40/80, a little 20/40 mixed in there), I feel like a 1/2 newb. So why resist it? Time to start posting simple newbie questions and work from there.

Aggressive 5-handed 30/60 game (which you're in because even though the table overall is 30/20, the guys two and three to my left are pretty tight and predictable, ~25/13 players).

You're in the CO. UTG (very aggressive guy, PokerHud has his stats as 35/30, seems like a good player, not a maniac) raises. You have ATs. Reraise, call, or fold?

On that note, what's the minimum you need to pop it to three bets?

My thoughts after I get some responses.
