Can you please explain in Chinese what "we will random 3 openings to be used by both players as the black from 21 openings applied in official gomoku contests to ensure the equality further more." means...
Thx.

21 openings in all, randomly choose 3 to be used in one match for both players. That is 3*2 = 6 games per match.
