Game Theory

Recently, I am trying to play all different kinds of games, from chess to cards. Sometimes, I have to play those games until midnight. Not kidding, overworked graduate student play games until midnight. Actually, it is not that difficult to play those games as long as you don't have to think about the theory behind those games, such as those subgame perfect equilibrium, sequential equilibrium, and etc. Once it gets to that point, it is not funny to play anymore. Sometimes, my brain refused to work whenever I put the game out. Oh, "game" theory~
