We are suggesting a scoring system in this study as follows: the inferior can play a game on equal terms with the superior by making good use of the handicap. We are compared three kinds of scoring system, System 1(conventional scoring system), System 2(conventional scoring system with the handcap), and System 3(no-advantage scoring system) using the Monte Calro simulation. We know that System 2 increases the possibilities for the inferior play to score sets, and System 1 and System 3 have a tendency to make a more equal set. In conclusion, to introduce a handicap into a conventionl scoring system would allow one to play a more competitive game in addition to being easier.
