This isn't quite Newcomb's Problem, though.
Consider this: You have essentially the same set up, and you're a one-boxer, so you walk up and take your million dollars out of box B.
And then Omega comes back and says, "Oh, by the way, want to open Box A too?"
And you say, "Um. Okay?" And open Box A, and get a thousand dollars. Or not. Doesn't really matter - you already have your million dollars, so you have nothing to lose by opening Box A.
This differs from the traditional two-boxing argument in one very important respect: you get new information in the middle of the experiment. Your single Omega-predictable algorithm doesn't have to "change its mind" in the middle, it gets interrupted.
This is essentially what (might be) happening here. Harry has opened Box B and found a dead Hermione inside. That's set and done. Assuming that he has reason to be believe that Box A will help him more than it will hurt him on average (and won't contain, say, a dead/mindless/insane Fred and George), he has no reason not to open Box A.

Are you describing Transparent Newcomb's problem? If so one should still one box when you see that the large box is empty. (I am not sure whether this maps precisely to the marauder's map issue, I haven't read the relevant chapter.)
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 94. The previous thread has passed 200 comments.
There is now 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.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22.
