Picture a long tennis match squeezed down to one rally. Two hours of running, and now one ball decides all of it. That squeezed-down thing can be looked at from two sides. Look at the scoreboard and you see a situation: it is match point, and the court goes quiet. Look at the player and you see a chance she has been handed, one she can take or drop — and if she drops it, another one may come, which is why they can be counted.
