Bridge Conventions (List)Jump Shifts may be used to show both a real suit and a fit for partner's suit. This usually occurs with a passed hand (a non-passed hand showing weak jump shift, strong jump shift, or splinter depending upon partnership agreement).
Jump Shift Shows Fit
A bidding convention is an agreement between two players on a different meaning of a bid in the card game bridge. These agreements are made so that partners can more quickly determine which contract, with both their cards, they can win together. Often, conventions are forged together into one, which is then called a bidding system.
