A woman sits on a rug next to a shirtless boy who is looking in the direction of a checkers board that includes several pieces.
A woman and her son play the third of a best of three checkers tournament.
No way to know that the boy is the woman's son and that they are playing in a checkers tournament.
You can look at a checker set without playing the game. A checker board and pieces can be set up without someone playing the game, and without the set being used in a best of three tournament. A checker board can be used to play a single game, or it could be set up without being played at all, so it's impossible to tell if it is being used for the third game of a series of games. A woman can sit next to a boy without the woman being the boy's mother.
A woman may sit next to a boy without playing and the boy may not be her son if he is the son of someone else and the boy may not necessarily be in a tournament because a boy may play and not be in a tournament and the boy may not be playing merely because he is looking at the checkers board and it may not be the third game as there can be any number of games.
