Thor is the first combatant smart enough to realize Shaw no selling all thors physical attacks. He'll try lightning, he'll have it thrown back at him. Then I think he'll get wise, he'll choke Shaw out. Movie Shaw only kept the power he absorbed for a single attack, so it will be Hit for Hit, lightning strike for lightning strike and after every attack shaw makes, he will need the re-charge from the following blow, so technically Thor could tank a hard attack then go in and choke a gimped, spent Shaw. Plus movie shaw is a boaster, if he reveals his power via gloating, Thor can fight around it.
