grandmasters are lightyears better than cms
still a master has some low chances to beats a grand master, but a casual player with no rating has absolute 0 chance to win vs any master.
the chance to win is calculated with the difference of rating
top = 2800 elo (maybe outdated, unsure those days)
grand master= 2500 - 2700 elo
international master = 2300 - 2400 elo
master = 2100 - 2300 elo
expert = 2000 - 2200 elo
casual player with no rating = 600-1000 elo
almost all players with rating over 2000 were already playing tournament when they were kids.
