I'm having a similar problem online, I use to be able to push/call the 4 Bet and catch Jacks in the act, but now it's at best AKs/u or at worst AA-KK. If it's a 4 Bet shove, then sometimes it's either AKs/u or QQ-JJ, but even then I'm going to start dropping AKs/u or QQ-JJ.

Does any one know if AK is still in people's 3/4Bet range on those stakes?
