It usually contains a small amount of anti-caking agent to prevent clumping and improve flow. Although most often produced in a factory, powdered sugar can also be made by processing ordinary granulated sugar in a coffee grinder, or by crushing it by hand in a mortar and pestle.

New input: The Open is a 72-hole stroke play tournament contested over four days, Thursday through Sunday. Since 1979 it has been played in the week which includes the 3rd Friday in July. Currently, 156 players are in the field, mostly made up of the world's leading professionals, who are given exemptions, along with winners of the top amateur championships. Further places are given to players, amateurs and professionals, who are successful in a number of qualifying events. There is a cut after 36 holes after which only the leading 70 players (and ties) play in the final 36 holes on the weekend. In the event of a tie after 72 holes, a four-hole aggregate playoff is held; if two or more players are still tied, it continues as sudden-death until there is a winner.
Solution:
is there a playoff in the british open?
