With AK or AQ OOP I'll raise about 4x the BB then if I get re-raised from someone in LP I'll 3 bet their raise with AK 100% of the time and about 50% of the time with AQ, the other 50% or so I'll fold. (with AQ it depends on my read of the person, if they are LAG I tend to reraise, if they are a rock I tend to fold).

If I decide to raise with anyother Ace OOP (AJ and down), if I get raised I will usually fold around 90% of the time.

And like I said with in LP I always 3 bet a raise with AK, whether the person is loose or tight. With AQ I'll more often fold to tight players or people I don't have a read on and reraise vs loose players.
So do you really always 3-bet with ak when ur early position raise gets repopped, even by a tight knit? I guess if it works for u that's great, but that IMO is far too aggressive (in cash game, not in tournies obv.). It's one thing if your playing against an extreme LAG maniac who is reraising preflop at least once an orbit, but if u are playing a tight player his reraise range against an early position raiser may be only jj-aa, ak, and sometimes minus the jj and ak. There are some players that hardly ever reraise, and when they do, I'm normally bailing with less than AA or KK. Now against loose reraisers, I agree AK is a repop (altho it's much better if you know ur opp. is capable of folding an 88 or 99 and isn't a complete maniac). Overall, I'd say my line with ak in cash assuming a call doesn't pot commit, in which case I generally push, is somewhere along the line of 35% raise/ 30% call/ 35% fold. These percentages are only when I am oop, when I am in position (i.e. against sb or bb), i tend to smooth call more often.

I think i definitely need to be cold-calling out of position alot less, as often times I get caught in between a raise, so maybe I should be reraising more, but I can say pretty definitively that if you are reraising ak a 100% of the time, it is -EV against some opponnents.
[Note- those figures for me are from all positions outside of bsb play, when my early position raise with ak gets reraised I probably fold more, and raise even less]

Now with AQ, u really 3-bet 50% of the time? Wow, that's very aggressive. I only reraise AQ there against the loosest opp.'s, and even then I'll sometimes call and try to outplay them postflop. Against any fairly tight play, I think u need to realize that making a play like this in cash game with aq is OK from time to time, but it is in effect, a BLUFF. AQ is ahead of no half tight players range possible hand. ANYTHING that willget called in this spot is absolutely dominated. I guess if you can get your opp. to fold a decent amount of the time it's worth it, but u say u are only reraising against the looser opp.'s, so I would only suggest thisagainst loose players who know how to fold a hand. My percentage would be probably 15 Raise/10 call/75 fold with aq from earlier position, 25/15/60 from mid,and then I don't really start playing it real aggressive until late position/bsb.
