Bridge World Standard
Bidding system in the card game contract bridge
From Wikipedia, the free encyclopedia
Bridge World Standard (BWS) is a bidding system in the card game contract bridge, first developed and serially published in 1967-69[1][2] as BWS 1968[3] by The Bridge World magazine. Like the Standard American Yellow Card (SAYC), it was intended "for use by impromptu or casual partnerships" and "as a basis for discussion by those who wish to formulate their own system."[4]
The system was updated as the BWS 1984,[5][6] BWS 1994,[5][6] BWS 2001[7] and BWS 2017 editions.[8] It is based on majority preferences of polled[clarification needed] experts and readers of the magazine.
The system shares some similarities with Standard American and 2/1 game forcing, but with many advanced treatments.
