In chess, there's a truism:
The weaker the player, the more they believe in luck.

i disagree, many wise man said: the more knowledge i got the more i realized that i know nothing. I have no prove but its my honest believe that many strong players believe in luck. Maybe you sleep bad and bang you play bad. There are many many factors of luck.
