A5s in the BB - A little lost

[Somekid]

I'm trying to make the shorthanded jump but my game needs a lot of work. I'm currently going through my hands at 1/2 6max and analyzing my play. This hand had me a little confused. I think check/calling the flop was a better plan. Also I think the river play is right, but correct me if I'm wrong. Sorry about no reads but I played this hand a while ago. Thanks.

the flop bet really doesnt accomplish much, its going to get bet anyway, and if the PFR raises, CO isnt folding anything you dont want him to call a single bet with. It also leaves you out of position and a little lost on the turn if you get raised

river looks fine to me given the rest of the hand
