Vulnerable - A Vulnerable condition
may occur on one, both, or neither side of the table, depending on the
hand in a match. In Rubber Bridge, the state where the side has won a
singular
game. In Duplicate Bridge, the condition where the side will enjoy a
higher game or slam score, but incur additional penalties for a failed
contract. Vulnerable is sometimes
referred to as the color "red". Thus, "Red versus Red" means both sides
are Vulnerable.
