Bridge World Standard (BWS) encapsulates common American expert practices, determined by polls, as a set of partnership agreements. It is used as a framework for problems in The Bridge World's Master Solvers' Club, by impromptu partnerships and as a basis for discussion by those who wish to formulate their own system. https://www.bridgeworld.com/indexphp.php?page=/pages/readingroom/bws/bwscompletesystem.html
