Reverse (bridge) - Jump Reverses

Jump Reverses

The term "jump reverse" denotes a jump bid in a suit in which a non-jump bid would be a reverse. Jump reverses after a major-suit response carry a special meaning. Most expert partnerships utilise this bid to denote game-going values with shortness (often specifically a singleton) in the suit bid and support for partner's major suit. An example of a jump reverse is:

1♣ – 1♠; 3♥

Partnerships utilising this agreement commonly agree that in this situation a splinter bid (i.e. a double jump in a new suit) indicates a void. This is also the understanding used in Bridge World Standard, though other options may also be used.

Jump reverses after a minor-suit response commonly show splinter raises, too.

1♦ – 2♣; 3♥

Jump reverses after a 1NT response to a minor opening are often used to indicate game-going values with shortness in the suit bid (a singleton or void) and six cards or more in the minor suit opened. This agreement facilitates partner in deciding the final contract (in most cases 3NT or a game or slam in the opened minor).
