Make it 40c preflop, then cbet at least 50c into the 75c pot. Fold to the minraise. check/fold turn. do not bet that river, that was the worst possible card you could've seen

you seem to have had a read that this guy just bets with air. if that's the case, raise him. It'd be cheaper to 3bet his minraise on the flop then call that and two more streets worth of betting, while having no idea where you are in the hand.
