Unfavorable Vulnerability - 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 other side has won a singular game.
In both Duplicate and Rubber Bridge, the condition where a game or slam bid and made by the
oppositions would receive a higher score, but would incur additional
penalties for a failed contract. Unfavorable Vulnerability is also known as
Red or "Red versus White" (although this board uses the color black instead
of white). See
|On this Duplicate board, North/South have unfavorable
vulnerability (opponents are "white")
In Rubber Bridge, the scoresheet
would show only North/South have made a game (earned 100+ point score in
prior game towards Rubber)
