|The illustration above is a detail of the painting Three Card Monte by Max Ginsburg|
Three Card Monte, also known as Find the Lady, is a "game" where you bet on the location of one of three face-down cards. You always ultimately lose. The person handling the cards can switch them using sleight of hand, and a team of people surrounding you - who seem to be innocent bystanders - are all in on the con and will convince you to bet on a "sure thing."
