There are finite games - where you have a limited number of shots. And then there are infinite games - where you can have as many shots as you like.

(With thanks to James P. Carse for the distinction).

Cricket is a finite game. If you’re a batsman in a test match, you get two innings – two chances – to bat. It doesn’t matter how good you are or how quickly you run out to the middle, you still just get the two. Even if you work through the night, you’re never going to get more than two. Even the great Don Bradman only ever got two innings per test match.
