Güzin Müjde Karakaşlı

She grew up playing volleyball for 11 to 12 years in the farm team of the local Denizlispor Club during her school years.[2][3] In the final year of high school, she took a break from volleyball to prepare for university entrance exams. During this time, she started going to a billiard hall, where pool and three-cushion billiards were played in separate rooms. In the beginning, she played pool billiard with her friends. However, she became curious about three-cushion billiards, because she found it more creative. In 2009, at the age of 18, she switched over to playing three-cushion billiards. She has said that "her advanced knowledge of geometry helps her much in this branch". The manager of the billiard hall invited her to the Turkish Championships. There, she enjoyed playing the sport so much that she chose billiards over a volleyball career.[2]
