Pass is a call whose natural meaning is unwillingness to make any other calls. Normally, you passes when

  • you have nothing more to say, and
  • your partner has not made a forcing bid.

The only correct form, when spoken, is the single word pass. When bidding on a bidding sheet, the correct form is a '/'. Abbreviations used in literatures include P, - and /.

A natural pass is always non-forcing.

Pass is (usually) a limit bid.

However, in some situations, a pass may be artificial and forcing (Forcing pass):

  • DEPO, DOPI, ROPI -- converts pass to a constructive response to Blackwood after interference.
  • Strong pass systems -- A pass when unopened indicates opening strength and forces partner to open the bidding.
