Taigi competition is in many ways more like Olympic-style couples ice skating than a martial arts contest. Taigi competition involves partners performing certain sets of taigi before a panel of judges, who rate the participants according to gracefulness and whatever other criteria show that they are moving with proper Ki (energy). The best-rated pair wins (in contrast to a competition in which individuals must physically defeat others). Thus, those who compete in taigi competitions have usually practiced extensively with their partners --- something reminiscent of paired ice skating.
Even this form of competition, however, has drawn criticism from some members of the Ki Society. Some people hold that aikido, by its very nature and philosophy ("The way of harmony"), should never encourage people to strive against other people.
