Checkmate
In all of the descriptions of perilous situations that I have studied, arising during adventures on the high seas or in the high mountains, or during armed conflict, a single mistake rarely proves fatal. More often than not, death comes as a result of a sequence of bad choices which reinforce each other. These choices may not appear bad at the time–but they certainly do in retrospect! The end result is a situation in which no further steps can be taken that would not be either harmful or futile. This is the essence of checkmate: no moves left. At that point, none of the previous moves can be undone. Nor do they even exist, really: they have gone off to an imaginary universe populated by the regretful ghosts of those who didn’t make it.
