Lead or repot on the flop. As played check/fold the river, there's nothing you can beat and I don't think players at this level would turn their made hands into bluffs on this board at this level. I don't hate the $1 blocking bet though as I think you're rarely getting raised as a bluff (and I think say a $7 blocking bet would probably be worse as a $1 blocking bet basically accomplishes the same goal). Once he minraises your tiny bet, you should call b/c you're getting ridiculous pot odds though.
