Off-topic, but I dislike chess and adore chess960/fischerrandom chess for essentially this reason. It's almost disheartening enough to want a different hobby when you review an online game and realize what you thought was a clever solution to an interesting "puzzle" of a board position was really just one you learned by experience a week ago. More variety in piece arrangement makes playing feel far more like doing chess problem solving than remembering the last time you messed up the same chess problem.
