in 1/2nl and 1/3nl games, 3-bet ranges are heavily skewed to AA/KK, like 90% of the time a 3-bet is AA/KK at this level
at 2/5nl, 3-betting ranges are JJ+, AK with 70% of the weight being QQ+ if eff stacks are 100bb
ironically, 3-bet calling ranges in 1/2nl, 1/3nl, and 2/5nl are ridiculously wide especially when oftentimes eff stacks are under 60bb. Players will call 3-bets with 22+, SCs, S1Gs hoping to get lucky and putting the preflop 3-bettor on AK... And JJ/QQ or notorious for stacking off to preflop 3-bettors as long as the flop/Board contains no A or K
