I am kind of new to RIO so I am just posting my hand like this. I also don't get how posting a HH works (I just keep clicking next but nothing happens).

I isolate the weak player with my AQ and get 4B by a reggish unknown player. The interesting spots are the turn and river imo and whether I should bet turn (that would be all in for slightly more than pot) or Xb. I decide to check because betting will not really accomplish much except him folding weaker hands (except maybe KQs), if I Xb I might get him to call a river bet with JJ or KQ. How do you guys feel about betting versus checking?

The river sucks because JJ now beats me. He ships and I am left to wonder whether he will do this on AK (or even other weaker hands that he decided to 4B). Given that I tend to call too much I decide to make a fold. Any comments on calling vs folding?
