Black moves first

Category: Game rules
Details:
In checkers, the person playing with black pieces moves first. Who plays with black is chosen at random.

Where I learned it:
During a game, when double-checking the rules as to whether a regular piece can jump diagonally backwards after the first jump (it can't).
