King Of The Court is a type of tournament in which players rotate partners until, ideally, everyone has played with everyone else. At the end you see which individual player won the most, and that player is anointed King. It's a way to make an individual contest out of a doubles event.
If you look at the results page, you'll see results for a number of KOC tournaments held in San Diego from 1999 to 2005. Those were designed around a field of 8 players. A simple 8-player format ensures a reasonable mix of matchups.
