I play AQ like I play JJ and 1010. Open if nobody has yet, if it gets raised I'll throw back another raise. If it gets raised again I'll usually just call. If the flop comes 3 undercards I'm usually willing to go all-in and play AQ the same as JJ.
Though if a K or J comes on the flop (with AQ or in JJ's case, Q or K), then I'll throw it away. It sucks to play short stack after one of those scenarios but you have to know when to fold.
I won't always though, like if my opponent is 4 betting his 88 or AJ or whatever I'll maybe mix up my play and play it aggressive 1/4 the time. 3/4 of the time I end up folding when met with aggression...
odds of someone having QQ, AKs, or KK/AA are too high.
It also depends on what limit we're talking... in freerolls I don't really care at all. I'll go all in with any ace in the first 20 hands, unless it's some private league. Ace-high in freerolls before the first break is the best hand the vast majority of the time... people overplay their suited connectors, or just straight up play dumb. I'll admit I've done some pretty stupid stuff in freerolls, but I don't wanna waste time on them for too long. I'm the type of guy who will play like one of the freeroll morons until I have a decent stack.
If I'm 3x the buy-in I also likely will post and fold until first break. Trying to play serious against people who don't care at all just ends in frustration. You're gonna get sucked out way too much with an insane amount of loose calls. Nobody in freerolls plays well until there's about 10% of the pool remaining.
I play a lot different when there's money on the line though. Freerolls I kind of do just for amusement :3
