This challenge is for teams with less than 750 players. The vegan and vegetarian chess team welcomes the September autumnal and vernal equinoxes. Good luck and good games to both teams and all players! "The September equinox (or Southward equinox) is the moment when the Sun appears to cross the celestial equator, heading southward. At the equinox, at the equator, the Sun rises directly in the east and sets directly in the west. Before the Southward equinox, the Sun rises and sets more to the north, and afterwards, it rises and sets more to the south. The equinox may be taken to mark the end of summer and the beginning of autumn (autumnal equinox) in the Northern Hemisphere, while marking the end of winter and the start of spring (vernal equinox) in the Southern Hemisphere."
