What is the actual definition of a "show court"?
I thought I knew, but am confused now.
Let us take the USO for example.
I initially thought that there were four show courts, as confirmed by this:
How many total courts are there on the grounds of the USTA Billie Jean King National Tennis Center?
There are a total of 22 courts on the grounds of the USTA Billie Jean National Tennis Center. Four "show courts" (Arthur Ashe, Louis Armstrong, Grandstand and Court 17), 13 field courts and 5 practice courts.
But, here they mention that there are six(They also include Court 11 and 13 here)
