If I have AQ and they 3-bet, I think "thanks for telling me" and fold my hand.

[/ QUOTE ]This is what makes 3betting people with hands like 89s very profitable.

I mean, I usually fold AQ to a 3bet, but I do pay attention and if it seems like someone is 3betting a little more often than they should I'll sometimes 4bet with a hand like AK or AQ (since these hands make AA less likely, have the chance to outflop a tricky QQ+ player who just smooth calls, and are easy to comfortably fold to a 5bet shove).

Another trick I sometimes use is if I notice a particular player is getting out of line with 3bets, I'll open for a minraise with AK/AQ with a plan to 4bet if I am raised- this has the dual effect of inducing light 3betting and making my 4bet a little bit cheaper. I only do this if I've been mixing up my PF betting sizes and minraising with some hands (Which I haven't been doing lately). It is REALLY hard for most decent players to call a minraise/4bet line with anything but a premium hand.
