I find people tend to be really tight in their reraises, so it is better to flat call a reraise regardless of whether you have a big hand or not. A lot of times if you have AA you cause someone to fold, but if you have AK, you get allin against AA or KK.

I play aggressively preflop, so I get reraised more than most people. If I think someone is making a play on me, then I may 4-bet without a big hand or 4-bet with a big hand thinking they won't believe me and give me action. I Or I might have AA and think the other person has QQ-KK or AK, in which case, I will 4-bet looking for action.

For example, I posted in CO and open raised with AKo. A regular who knows my style and plays back at me reraised. I 4-bet and he folded. In this case, I was not that happy with playing AK postflop without the initiative, and thought he would fold to my 4-bet or flop push.

In general, some people are so tight with there reraising standards that it doesn't make sense to 4-bet a lot.
