You are sitting around the table with a crony you’re in cahoots with. You and the crony decide to play the following silly game. (The two of you run a store called the Cis-Patriarchal Pet Shop that sells nothing but vicious robotic dogs. The loser of the game has to clean up the yard where the dogs roam—not a pleasant chore—so the stakes are high.) We start with n ∈ Z≥1 stolen credit cards on a table. The two players take turns removing cards from the table. In a single turn, a player can choose to remove either one or two cards. A player wins by taking the last credit card. (See Figure 5.26.)
