First of all, we will intensively discuss several Zero-Sum Two-Person Games, with special reference to the Games of Matching Pennies. New graphical illustrations will be attempted for clarification of the matter. Then, we will turn to novelist Edgar Alan Poe's best story The Purloined Letter, showing how the Poe story may challenge the validity of Neumann-Morgenstern approach. Next, we will shed new light on Conan Doyle's famous story The Final Case as a variant of the Games of Matching Pennies. Finally, we will pick up the Game of Stone, Paper, Scissors, which constitutes another important member of Zero-Sum Two Person Games., Discussion Paper, Series E, No. E-20, pp. 1-44}, title = {The Games of Matching Pennies and of Stone, Paper, Scissors : Critical Reassessment of Zero-Sum Games}, year = {2022} }
