Invented by great theoretician but mediocre player [Ernest Mipplington]?, who also developed the complementary Mipplington Convention, this is the standard way of measuring move difficulty. A simple move has a Hughes difficulty rating (HDR) of approximately 0.2, a typical shunt around 1.2 and an average Czukay Manipulation in the range 3.7 to 4.9. The hardest move ever played occurred in the semi-final of the 1976 World Championship. It took the Andorran Champion (whose name has sadly been lost) from Amersham to Chalk Farm with all the diagonals closed, six lines quartered, fifty-two stations bulkheaded and sixteen more blocked. It took him almost two hours to work out. The HDR was later found to be 396.5.
