No stats, no reads. I prefer to flat AJo pre in this spot because I think a 3bet is a little too thin vs a HJ/MP open. Flop flat is standard imo, raising wouldn't be terrible but it could be overplaying what's still just 1 pair. I improve to top 2 on the turn, and villain barrels again. I though about raising, but I feel like against any decent opponent I'm gonna iso myself against sets and KQ and he could very well fold AK and AQ that don't have a FD. Villain barrels big on the river, and I'm left wondering what I beat. I don't see villain betting so large with AK and AQ because he simply can't get called by enough for that large of a bet. It seems to me his most likely hands in this spot are KQ, TT, 77. Very occasionally he could have AT, but not enough compared to those other hands for me to justify a call imo.
