Peter Gilchrist set the world record for highest break in billiards (1346) under modern rules, at the New Zealand Open Billiards in Hamilton. On 14 February 2014, he scored his second 1000 break at the World Billiards Irish Open. He is the only player of the modern era who has scored more than one 1000 points in tournament break.

English billiards, called simply billiards in the United Kingdom, where it originated, and in many former British colonies such as Australia, is a cue sport that combines the aspects of carom billiards and pocket billiards. Two cue balls (originally both white, with one marked e.g. with a black dot, but more recently one white, one yellow) and a red object ball are used. Each player or team uses a different cue ball. It is played on a billiards table with the same dimensions as a snooker table and points are scored for cannons and pocketing the balls.

Scoring:

Cannon – striking the cue ball so that it hits, in any order, the other cue ball and the red ball on the same shot: 2 points.

Winning hazard (or potting, in snooker terms) – striking the red ball with one's cue ball so that the red enters a pocket: 3 points.

Losing hazard (in-off in snooker terms) – striking one's cue ball so that it hits another ball and then enters a pocket: 3 points.

A break consists of scoring points for consecutive shots. The break total stops once a shot is made and no points are scored from that shot.
