Bridge World Standard (BWS) is a bidding system in the card game contract bridge, first developed and serially published in 1967-69[1] as BWS 1968[2] 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."[3]
The system was updated as the BWS 1984,[4][5] BWS 1994,[4][5] BWS 2001[6] and BWS 2017 editions.[7] 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.
