is by means of a playoff, whereby those players who have tied for the lead replay a set number of holes. If still tied after those holes, then further sudden-death holes may also be played until a winner emerges. Ties in professional golf are generally settled by means of a playoff. Different tournaments have various formats for their playoffs, ranging from another full round, as employed in the U.S. Open, through to a three- or four-hole playoff as used in the PGA Championship and the Open Championship (British Open), to straightforward sudden death, which is used in most tournaments including the Masters Tournament and all other regular PGA Tour and European Tour events. In the longer playoff formats, if at least two players remain tied after such a playoff, then play generally continues in sudden-death format. Count back One method of breaking ties commonly used in amateur competitions, especially when a playoff is not practical and used in professional tournaments to seed players in knockout rounds (such as the World Super 6 in Perth, Australia) is a scorecard "count back", whereby the player with the lowest cumulative score over the last 18, 9, 6, 3, or 1 hole(s) is declared the winner.
