I think 22 is mostly valuable for set mining, but you may call his cbet if he does that often on this flop, but that's about it as you are looking for showdown not big pot here. So I would check bad turn as he will fold here most of his A high, but any other pair beats you even FD with overs has ~44% equity here. On blank river like this you may fold reasonable bet depending how aggro and how capable of betting A high or other bluffs your opp is.
