Mind sports should be in the Olimpics.
Мнение + аргумент. На Русском или Английском, не важно.

I think there's no need to include them in the Olympics. Traditionally, the latter consists of merely those competitions that show participants' physique: health, strength, and so on. People engaged in intellectual activities may take part in mind contests, which can be international and honorable, too.
