It fits the person doing the blackmailing (in a world where you reject my threat, I will act against my local best interest and blow up the bombs), just as well as the person being blackmailed (in a world where you have precommited to bomb me, I will act against my local self-interest and defy you).
You omit some counterfactuals by framing them as located outside the scope of the game. If you return them, the pattern no longer fits. For example, the blackmailer can decide to not blackmail on both sides of victim’s decision to give in, so the utility of counterfactuals outside the situation where blackmailer decided to blackmail and the victim didn’t give in is still under blackmailer’s control, which it shouldn’t be according to the pattern I proposed.
I don’t quite see your point. If you take a nuclear blackmailer, then it follows the same pattern: he is committing to a locally negative course (blowing up nukes that will doom them both) so that the probability of that world is diminished, and the probability of the world where his victim gives in goes up. How does this not follow your pattern?
You assume causal screening off, but humans think acausally, with no regard for observational impossibility, which is much more apparent in games. If after you’re in the situation of having unsuccessfully blackmailed the other, you can still consider not blackmailing (in particular, if blackmail probably doesn’t work), then you get a decision that changes utility of the collection of counterfactuals outside the current observations, which blackmailed (by my definition) are not granted. The blackmailed have to only be able to manipulate probability of counterfactuals, not their utility. (That’s my guess as to why our brains label this situation “not getting blackmailed”.)
I need examples to get any further in understanding. Can you give a toy model that is certainly blackmail according to your definition, so that I can contrast it with other situations?

I don’t understand. Simple blackmail is certainly blackmail. The problem here seemed to be with games that are bigger than that, why do you ask about simple blackmail, which you certainly already understood from my first description?
