Bridge world standard defense

 

BRIDGE WORLD
STANDARD DEFENSE

Bridge World Standard Defense is a set of defensive-carding agreements based on the methods most popular among American experts. It is used as a format, style, and partnership agreement for defensive card-play. The advantage of a Standard Defense is that it permits both partners, who are acquainted with the format, to readily conform to the standards of the agreement without much prior discussion. This interprets into a situation where both partners readily understand the leads, signals, and discards of the other player.

The Bridge World Standard Defense agreement is not complicated andconforms to most standard partnership agreements with very few deviations.
