[Question] Examples of Acausal Trade with an Alien Universe?

I understand the basic concept of counterfactual trade, and I can understand some examples where it can make sense to trade acausally between two different histories of our familiar world; for example, in Embedded Agency, Scott G and Abram discuss a game where Alice receives a card, either a king or an ace, and can either reveal it to or hide it from Bob, who will guess a probability p that the card is an ace. Bob’s incentives are such that he wants to assign maximum probability to the actual outcome, while Alice receives 100*(1 - p^2) points no matter what her card is- so she wants to do her best to make Bob think she has a king.

In this example, one might naively think that if Alice has a king, she should reveal her card, so that Bob will guess p=0, earning Alice the maximum reward. However, under this policy, when Alice has an ace, Bob would be able to infer from Alice hiding the card, that the card is an ace, so he would guess p=100%, and Alice will receive 0 points.

If Alice instead decided to follow the policy of never revealing her card, Bob will be forced to always guess p = 0.5, earning Alice 100*(1 − 0.5^2) = 75 points each time; since Alice prefers a 100% chance of 75 points over a 5050 shot at {0, 100}, Alice should actually hide her card even when she has a king. This is an example of counterfactual trade that makes sense to me.

Similar logic applies to glomarization, and Newcomb’s Dillema also has an acausal trade flavor to it, which is similar to some dynamics that appear in normal human interactions.

However, my question is:

Do you know of a concrete example where acausal trade with a universe completely different from ours, with laws of physics different from ours, actually makes sense?

I struggle to think of such an example, where it’d both be harder for us to do something than it would be for an alien, acausally correlated species to do it, and where there would exist an acausally correlated species that would want to reward us by doing so in return for something more valuable that we can provide. Are there any such examples, or is it a valid conjecture that such acausal trades wouldn’t ever make sense?
