BTN has been very loose and aggro thus far running 33/28 and rfi from BTN is 71%

With antes in play think the defend is good

On this board I imagine he bets most of his air if it has any equity or bd draws and checks back hands with some sdv.

Turn is close as I dont really see why his range for checking back the flop which is mostly A high or weak pairs decides to now bet on this blank card. Given his wide range I think he can be betting air that just decided to give up on flop

On river I don't expect him to have many ax hands as there is no reason to start betting those on the turn. The ax could be perceived by some as a good bluffing card though I feel I play A high this way quite frequently. Once he checks flop I cant really think of many value hands that bet twice here so thought he was weighted more heavily to bluffs. Would most people be bluffing with their air on this flop or are people a bit more balanced in this scenario these days?
