In table tennis, try your best to build an early lead in points, try your best to win the first game, try your best to win the match 3-0.
One of my students recently lost to a player who had an amazing forehand and a terrible backhand. This opponent’s forehand was at least 1900-level and his backhand was around 800-1000 level. After losing, I asked my student why he played so many balls to the forehand. He responded by saying, “Well, I didn’t want my opponent to know that I knew his weak point.” What a terrible way to lose a match.
