*Which color you are allocated.
*Which opponent you will face.
*Wether your opponent implements a strategy you are familiar with or not.
*As dano2769 said, your opponent could drop dead during a game.

There is an element of luck in all games, just more in some than others. The amount of luck and skill in each game is, however, unique; some possessing more of one than the other. Chess for example has a high amount of skill compared to luck, where as dice has a high amount of luck compared to skill. Both have an element of it though.
