I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill, but time and chance happeneth to them all.
– Ecclesiastes 9:11, Holy Bible, King James Version
The ancients were accurate about the role of chance in human affairs. There are existing writings referring to luck and chance. The biblical verse is reminding us success is unpredictable, uncertain, because man does not ultimately control events.
Misfortune may occur at any moment. In the World Chess Championship, challenger Sergey Karjakin conquered the favoured world champion Magnus Carlsen in Game 8, thereby ending an accumulation of seven successive draws.
