thats a shocking way to play out of position really. if you get flat called on the flop you don't know if theyre on a draw or just a pair. so then you'll probably check the turn unless you pair and give them an extra card to hit. you're never winning worthwhile pots with AQ early on UTG. until i'm under 20 BB i don't play it UTG. assuming i have average tournament chips.
you have to also remember early on people will often flat call with AK behind a raiser. you hit your ace. you bet. they raise. you think wheyyyy he's got a weaker ace theres no wayyyy i'm beat. but..yeah.. it's only AQ man.
muck this shite utg. only gets valuable short-handed, in position or late in the day.
