Which of the following are 'sports':

Chess (can sitting down and thinking be a sport?)
Darts
Pool
Dressage (is this just, effectively, a 'which donkey has the prettiest hat' competion?)
Ice 'dancing' (although when Dave Seaman's involved, breaking bones, it becomes more interesting)
Anything with judges (halfpipe, skateboarding,gymnastics, etc.)

Thank y'all in advance.
