Sportsmanship  yes

Please make sure that you are always playing with good sportsmanship.  Keep smoke breaks to a minimum and make sure you are not doing things that will delay the match.  We all love the game, and we all want to win.  Always make sure that you both win and lose with the same sportsmanship and respect that you would like to have other players show you.

Refer to Rules of Etiquette document (which is a part of the WADA Rules).
