Query: On game psychology: an experiment on the chess board/screen, should you
  always "do your best", and why the programs with prescribed weaknesses cannot
  be our good friends?   It is noted that some unusual moves against a strong chess program greatly
weaken its ability to see the serious targets of the game, and its whole level
of play... It is suggested to create programs with different weaknesses in
order to analyze similar human behavior. Finally, a new version of chess,
"Chess Corrida" is suggested.
