What will you do if your opponent sharks you during a match? Like making noise using his feet during you serve. Making a lot of comments during the match like even if the ball is clearly out, he still insist that the ball went in. His intentions was to shark and psyche you up. What I did was to praise him after the match and said to him "that inspite that we lost our match, I am still very happy because the mere fact that you are the favorite, you sharked and dig out a lot of bag of tricks to win the game. That for me is respect for my skills."
