Peter Lines has had a long and successful career in snooker. He reached the final of the English Amateur Championship in 1999, and made it to the quarterfinals of China Open in 1999. His professional success began in 1991 when he became a professional. In the 1990s, he reached the quarter-finals in both the Strachan Open (Asian Open) and Strachan Open. 1998 saw him qualify for the televised World Championship stage.
While his career is mostly unremarkable, Lines' performance in the last few years of his career has been more than respectable. For the first ever time in his life, he made it to 64th place on the Order of Merit. The most impressive part of his season was a run at the German Masters, in which he reached the semi-finals and came close to victory.
He was enjoying a promising start to the 2011/12 season but suddenly felt under pressure. As the season progressed, the pressure increased and he began to lose matches at his four ranking events. At the end of the year, he was ranked just 57th on the European Tour. Fortunately for him, he secured a place on the tour for a further year, and he was also able to make it to the qualifiers of the World Championship.
He went on to play in two other major tournaments, defeating Ian McCulloch and Joe Perry. He also won a qualifier at the Players Tour Championships series (PTC), but it was not enough for him to be in the main tour.
In 2010, he won the UK Championship, but he was again relegated to the PTC events after the 2015/16 season. He has been playing in amateur tournaments ever since.
Lines' behavior during a match in China has been ruled inappropriate by the World Professional Billiards and Snooker Association. The World Snooker Tour has received a complaint about Lines' behavior during a match in China and has initiated an investigation. The World Snooker Tribunal will likely be referred to the formal complaint made by Xiao Guodong's staff.
On December 16, Lines was brought before the WPBSA and sentenced to a fine. The fine had an interesting side: Lines was found guilty for violating two rules regarding player conduct.
The first rule involved his replacement of the white ball after a foul and miss award. In this situation, professional players are not uncommon to temporarily hang up their cues. Brendan Moore was Lines' opponent. They argued over this matter. They claimed Lines had made an erroneous statement, but Lines maintained that Moore was correct.
The World Snooker Tour, on the other hand, stated that Lines used "swear words" and intimidation during the match. Lines also threatened to fight outside the arena.
