435152: 1) if a 1900 can't know if he's playing a computer ... what chance does a 1400 have? none.

You said: "computer won all the matches against human, not just by winning one single game" This is only a half truth. It is true that humans have been beaten in matches in the last several years. However, matches between computers and world champions have had by far more drawn games and are usually decided by one or two games.
