 If exposed inadvertently, depending on its rank, it may be a "minor" (2-9) or a "major" (10-A) penalty card; however, any card may become a major penalty card if played out of turn.In any case, the penalty card must be played at first legal opportunity, which allows the declarer to organize his play to take advantage of the situation.However, the offender may play an honor of the same suit instead of the minor penalty card.
