In a paper on "Hamlet"

In a paper on "Hamlet" I wrote in mid-1970s I say that the play could be considered a game of cards where the two players, Hamlet and Claudius, try their best to win, including resorting to cheating by spying on each other's cards. Claudius tries to understand what is on Hamlet's mind, Hamlet wants fo figure out whether or not his uncle is guilty of murdering his father. The play's whole characters are like cards in a deck of cards: Claudius is King, Gertrude Queen, Hamlet Jack, Ophelia Ace of Hearts, Two Grave Diggers are Two of Spades, Fortinbras and His Troops are Ten of Clubs, and Polonius is Joker
