  1. #The object of this file is to present positions in the opening in
  2. #which there is thought to be a unique best move. This test will only
  3. #be of much interest if the computer taking the test, is playing with
  4. #its opening book turned OFF. Otherwise a lot of the answers will be
  5. #directly in the book. Of course, it helps to have a book in non-book
  6. #positions because of transposition possibilities, but situations where
  7. #that is the case, are basically not represented in this file.

  9. #First, A. Alekhine: My greatest games of chess
  10. #1908-1937, 2 volumes in 1, Dover 1985. AlekhineI is volume I,
  11. #1908-1923.  AlekhineII is volumeII, 1924-1937. I'm going by Alekhine's
  12. #comments in which he says things like the move was "necessary" or
  13. #"best"; in nearly all these cases, something else (i.e. which Alekhine
  14. #considered to be a mistake) was played in the game.
