You therefore have information about the pack- which is, of course, in the
card-game situation that you mention, highly significant information.

"no situation being more likely" is indeed information.

blow my mind, and so I think I'll drop out of it (or at least try to!).

Politeness be sugared, politeness be hanged,
Politeness be jumbled and tumbled and banged.
It's simply a matter of putting on pace,
Politeness has nothing to do with the case.
