Luck in Chess
Chess is a game of perfect information - all the information about the game (the position) is available to both players. No pieces are hidden, no dice roll will determine how you can move next. Despite this, chess is so exponentially complex that no-one can foresee all eventualities - even Grandmasters or computers, so luck can play a role.
At my lowly level luck is even more evident - a good example is below from one of my casual blitz games.
Has luck sometimes played an important role in your games?
