Several players, such as Ronnie O'Sullivan, Mark Allen and Steve
Davis, have warned that there are so many tournaments that players risk
burning out. In 2012, O'Sullivan played fewer tournaments in order to
spend more time with his children, and ended the 2012/2013 season ranked
No. 19 in the world. Furthermore, he did not play any tournament in
2013 except the World Championship, which he won.
