like I would fold AA on a QKA board because everyone plays JT like all the time without fail cuz of Negraneau. Not sure about this one though, like 77 as a set is so much stronger than AA as a set cuz it's unlikely that someone else has the 4th 7 so you can make quads easier, in NL someone always has an Ace so I'd just muck like AA on the QKA board because of reverse implied odds and you'll have no outs to improve and you are behind like 95% of the time, I mean, I could pokerstove it, but I've already seen the results before, so just take my word.
