At which point the obvious next question for Voldemort to ask is, "What iss thiss power you sspeak of?", and then Harry would be pretty hosed. Moreover, if Voldemort discovers that Harry is trying to use tricky wording against him, he'll likely conclude (correctly) that Harry is not at all interested in being cooperative, and then kill him.
The problem as I see is this: Voldemort is smart. Furthermore, he thinks like Harry, meaning that Harry's plans will be especially easy for him to see through. Any sort of successful verbal trickery would by necessity have to be something that Voldemort can't decode easily, which, given the constraints, seems to imply that the solution should involve domain-specific knowledge more than general intelligence, which in turn screams "Muggle knowledge!" to me. One example of this is the material implication trick I suggested (which I know you've already seen; I added the link there for other possible readers). Can anyone think of any other such tricks?

Why? Doesn't Voldemort have an interest in not allowing the heat death of the Universe to happen? We could change the framing so it's more of an explanation of entropy and heat death than an apparent trick (As I think some on Reddit have already done.), but I think this has a fair bit of potential at least as a tactic for buying time to partially transfigure something or for gaining access to Hermione if not for outright persuading Voldemort to let Harry out of the box.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 113.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
IMPORTANT -- From the end of chapter 113:
