Rated Match Policy

On 15th March 2017, the UKBGF adopted its official results policy PDF, which is designed to establish a standard for the quality of results posted to this site.

The UKBGF policy is supplemented by local policies, which give club managers the freedom to define local rules that work for the way their events are run.

The manager for ThameGammon data on this site is Tim Spring.

The local policy for ThameGammon is as follows:

ThameGammon Club Meetings

ThameGammon club meetings are held on alternate Tuesday evenings at the Chilterns Fox, Ibstone HP14 3XT.  Members are encouraged to support the venue by ordering food, which should preferably to be taken early to avoid delays in play.

Competition Rules

All ThameGammon competitive tournaments will be played to the then applicable UKBGF Tournament Rules, available for download here. Any applicable local rules will take precedence if there is any conflict.

UKBGF Membership

ThameGammon members are encouraged to apply for and maintain UKBGF membership, currently £25/year.  Application form and information on membershp benefits can be found here.

Tournament format

At every meeting there will be a competitive tournament, open to all, and a social group. The competitive tournament may be split into two (or more) brackets, possibly with different formats (e.g. Swiss and Round Robin). 

Entries for the competitive tournament will close at 6.45 pm.  If you expect to be late, the TD should be informed by phone or on the WhatsApp group (email Administrator with request to be added).  Play must start by 7.00 pm latest.

Swiss competition pairings

Unless the number of players is 8 (or a multiple of 8), the Flexible Swiss format will be used.  This allows subsequent matches to commence as soon as a suitable pairing can be achieved by reference to completed matches.

If there is an even number of players, it will be played as 3 rounds of 7-point matches. The first-round pairings will be made at random and then by order of finishing the preceding match, adhering as far as possible to the principles of the Swiss format - i.e. in second and subsequent rounds, players are paired against others with equal wins.

If there is an odd number of players, there will be 4 rounds of 5-point matches. In each of the first 4 rounds, one player will have a bye (and can join the social group for that round).  The player with a bye in the second and subsequent rounds will be a loser from the preceding round. 

After four rounds, the pairings for a final (fifth) round will be formed from the 4 players with byes in the preceding rounds (who will have played 3 matches each) and the players who have each played 4 matches will take no further part.  In the fifth round, the 2 highest placed players (by number of matches won) will be paired, unless this produces a duplicate pairing.  If a duplicate pairing cannot be avoided, the results will stand.  Fifth round matches may be reduced to 3 points by the TD (if short on time) or by mutual agreement between the players involved.

Side pools

There will be a strictly optional side pool in the competitive tournament with a fixed stake of £10, which will be distributed according to the following principles.

Finishing positions will be decided on matches won. Tie breaks will not be used.

If there is a single clear winner and a single clear second place, the prize pool will be split 70:30.

If there is a single clear winner and a tie for second place, the winner will receive 70% of the prize pool and the balance will be shared between the entrants tied in second place.

If there is a tie for first place, players with one fewer match wins will receive half stake (if 6 or fewer side pool entrants) or full stake (if 7+ entrants) and the players tied in first place will share the balance. So, for example, if 2 players are tied in first place on 3 wins and 3 players tied on 2 wins, the players on 2 wins will receive £5 or £10 (depending on number of entries) and the players tied in first place will share the balance.

These prize pool allocation rules are subject to change at the TD's discretion to ensure a fair outcome in circumstances not considered.

UKBGF Ratings

All completed matches played as part of a randomly-drawn Swiss or Round Robin tournament at ThameGammon meetings will contribute to individual players’ UKBGF ratings.  The ThameGammon Club rating table is here.

Finalists are permitted to agree a reduction in match length but this must be accurately reported.

A match in which penalty points have been awarded will be rated unless it becomes a walkover.

Friendlies, walkovers, settled and unfinished matches will not be rated. The term ‘friendlies’ includes any match which is not part of the supervised tournament programme, even if it is played during a ThameGammon event.
