Athletic games: the idea of the game, where the final result (victory or defeat) is achieved largely at the expense of athletic qualities of the competitors.
Intellectual games: the idea of the game, where the final result (victory or defeat) is achieved largely at the expense of intellectual qualities of the competitors.
The relativity of these definitions is obvious. Athletic games (boxing, football or any other type) surely contain intellectual component. In every type of games we have to think. The majority of famous athletes today prefer to keep their personal athletic diaries where they describe in every detail all of their competition and training matters.
Standing apart from others is the third type of games: gambling and casino games.
The definition of gambling and casino games based on the idea of the game, where the final result (victory or defeat) is achieved by chance. In such kinds of games the athletic or intellectual or any others qualities of the competitors are not principal. Believe it or not but according to this classification poker belongs to the second category, intellectual games. Let's turn to the more detailed review of the latter.
Intellectual games. Games with almost perfect information and games with inexact information.
Games with almost perfect information: the idea of the game where all the game information (the position, the players' actions) is fully open to all participants of the game.
To tell the truth there is restricted information even in that kind of games. That is: every player has its own idea of the game action and these thoughts as a rule are unknown to others. Chess is the most striking example of intellectual games with almost perfect information.
