The C on the Card, Concealed or Closed and Definition (Article ID 144)

We often hear players refer to the letter “c” displayed to the right of a hand on the NMJL card as a “closed” hand. The proper term is a “concealed” hand. Incidentally, some players refer to the “x” hands as “open” hand . The property term for this type of hand is “exposed”.  It is acceptable to use closed for concealed and open for exposed with no penalty incurred.
