OK-bridge 2/1 is a duplicate bridge bidding system which is based on the two over one game forcing system but is additionally combined with the Walsh bidding. It is becoming popular with the internet bridge players on the OK Bridge website. This style of 2/1 bidding results from the combination of five bidding conventions and principles. Each takes on a slightly different meaning relative to their use in other bidding systems, but the combination here results in superior description of hands in terms of both high card strength and shape.
