- Support_double abstract "The support double is a bridge convention used to distinguish between 3-card and 4-card support for partner's suit response to one's opening bid in the scenario where his response is either overcalled or doubled by the opponents. A call of two in partner's suit indicates 4-card support and a call of double promises 3-card support; if partner's suit bid is doubled instead of overcalled, a redouble serves the same meaning as double. The convention was invented by Eric Rodwell in 1974.For example, after1♦ - (Pass) - 1♥ - (1♠) Double shows 3-card heart support 2♥ shows 4-card heart support Pass or other bids: fewer than three heartsA support redouble applies when Right Hand Opponent makes a take-out double of the response of one of a major:1♦ - (Pass) - 1♠ - (Double) Redouble: 3-card spade support 2♠ shows 4-card spade support Pass or other bids: fewer than three spadesThe convention came as result of the scenario where in competitive auctions, the opening bidder would like to show his minimal 3-card support for partner's suit on the possibility that partner has five or more cards in it. However, there would be a risk of a 4-3 fit, known as a Moysian fit which do not play as well as 8-card fits. Since the need to distinguish between 3 and 4-card support occurs more frequently than those cases where the opening bidder would like to make a penalty double over the opponent's 1-level overcall, the meaning of the double (and redouble) was modified to convey the conventional meaning of 3-card support.".
