  1. #Positions from HORT AND JANSA: "The best move" RHM Press NY 1980.
  2. #
  3. #Contributed by Hans Berliner, partially checked by him and HITECH.
  4. #Note: all analysis is due to Berliner, HITECH, and/or Hort+Jansa. In 4
  5. #cases so far Berliner/HITECH have found errors in H+J's solution.
  6. #("Books are full of errors," says Berliner, in the same breath adding
  7. #that he thinks H+J is an "excellent" book...) There also seem to be
  8. #plenty of typos in this file, presumably corresponding to cases
  9. #berliner has not gotten to checking yet (or berliner has caused his
  10. #own typos?)  namely:
  11. #
  12. #Possible typos and BUGS:
  13. #move d1a1  illegal; 0 matches; HJ.T25  I fixed this to be d1h1, which I think is correct
  14. #move e7d6  illegal; 0 matches; HJ.010
  15. #move f3e5  illegal; 0 matches; HJ.021  I fixed to be f4xe5, think this is correct
  16. #move e3c3  illegal; 0 matches; HJ.025
  17. #
  18. #HJ.053 has no indicated solution!! I do not understand Berliner's analysis line for it!

  22. #have solutions typed in.
  23. #
  24. #At present I am incapable of fixing these bugs since I cannot obtain a
  25. #copy of the H+J book. I would sure appreciate it if somebody who has a
  26. #copy of the book would figure out what is going on here. Berliner says
  27. #he is too busy to help.
  28. #
  29. #Note our 3-field forsythe format. The first position has: white on move
  30. #(note the "/w") and solution (2nd field) is d5. Label (the 3rd field)
  31. #is "HJ.A01".
