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.
