I like this hand.

Flop is a clear check. No point balancing or getting fancy vs a player we have no history with and who seems bad.

Turn is a clear call. Raising is a definite spew, yes we can maybe get villain to fold Ax but he seems bad and our line makes no sense so we just get called down way too often (and I think if you raise turn you have to follow through on the river to actually get him to fold anything and now we're really spewing!)

River I probably call. I think it's close, but he can conceivably show up with JJ/QQ/Tx and some bluffs here, although there are clearly a lot of hands that beat us in his range. Meh, getting >4:1 I think this just has to be a call without better reads. You obviously do get shown a better hand an awful lot here though.
