It's transparent Newcomb's problem but of the "perverse" variety where even when you see that the million is missing you're supposed to not take the thousand. The typical (e.g. in Good and Real) version just requires you to one-box when the million is there.

I do prefer the "perverse" variant. The typical version seems so trivial. I've already got defined-by-the-problem certainty about the payoffs. A few photons in my eyes adds little. To give the 'perverse' variant more emphasis I also like to add a small amount of random noise to Omega's choice so that the "one box when box empty" scenario isn't self-preventing.
