1500 people in the audience watching a carom billiards match. I was one of them.
Notice that they follow the very civilized policy of each player getting practice time on the table immediately prior to the match.
The event was organized by Ludo Dielis who has the record for consecutive points at 47/2 balkline in a tournament. The matches were to 400 points and he ran 400-and-out in five consecutive matches. In his next match he only managed a 10. The tournament was a pentathlon format, so he was also playing four other billiard formats, like straight rail and 3-C.
