The fact is folding AK wasn't that bad vs 3betting ranges of some players back then. When light 3betting become popular there was a period of over adjustment and crazy 3bet/5bet wars till people slowly figured those out but it's not like people were flding AK vs 15% 3betting range.
oh man, i want to go back to 2006
Regs were very good back then and they would hand your ass to you. It was just different game, weakier trackers, very simplistic huds, no massive datamining, less tools to figure out some GTO approximations and no material available on the internet for learnign to play. It's just much easier these days to learn to play decently.
Yes, the games were softer but it had nothing to do with level of play of the regs but with abundance of fishes who kept donating to the economy.
Just so you know, usual line-up in Party 6max "back then" was: Durrrr, Lolo (one of the biggest winners in online poker probably ever), Dang brothers, Cts and few others who later became recognized stars.
