The Thursday Invitation Pool League (TIPL) has been running in Haverhill since the early 1980s and is still as popular in the town as ever. The league invites all the pubs and clubs in and around Haverhill to join on an annual basis and then competes for most of the year in a typical pool league format.
The fixtures include a general reciprocating league as is common with just about all town leagues across the country. The TIPL is currently affiliated to the Cambridgeshire Pool Association under the English Pool Association and takes part in the County events where possible.
Also included in the annual fixture list are various knock-out cup competitions which include:
The league is run to a standard home and away fixture list and may contain one or two divisions depending on the number of teams that take part in the season. Points are awarded as 3 for an away win, 2 for a home win, 1 to each team for a draw and zero for a loss.
Straight forward knock out cups for all the teams in the league using a match format similar to a typical league match, with the only exception that an extra frame is played in the event of a 5-5 draw to decide the winning team going through to the next round. First team to 6 frames wins.
The Team Doubles Cup is played over 9 frames with three doubles pairs from each team playing against each other in a set order (the playing order is defined in the league rules). The idea is that every pair from each team plays every other pair from the opposing team once. First team to 5 frames wins.
Teams of 3 (4 people allowed per team) play over 9 frames in a specific order so that each player plays each of the 3 players from the opposing team. First to 5 frames wins.
Singles and Doubles entries into a typical knock-out cup with each round being drawn from the hat. A small fee to enter and all matches (except the final) being best of 3 frames. The Singles and Doubles finals are played on the Finals Night over 5 frames and represent the peak of the game of pool in Haverhill.
The Captain's knock-out cup is played on one night as scheduled by the league fixtures.
All player's results from all league games are entered into the rankings database, and the player who score the highest win percentage at the end of the season wins the title. Any final score over 80% is considered an excellent season's performance. Players must have played in at least 50% of the season's frames to be eligible for the rankings list.
