The Automatic Handicapping System (AHS) is the principal method by which handicaps are changed.
All players carry forward their indices from season to season. When a player's handicap is altered outside the AHS, his index is reset to the trigger point corresponding to that handicap [see Tables 4 and 5 below].
All singles games in CA Calendar Fixtures, Federation Leagues, inter-club contests, and Designated Club Competitions qualify for the system.
Designated Club Competitions are competitions for which all the following apply:
Short croquet, golf croquet, doubles, friendly games within a club, ad hoc games and abandoned games are specifically excluded from the system.
Friendly matches between clubs are included in the system, unless both clubs agree prior to the start of the match that the games will not be included.
The Tournament Handicapper must assign a handicap to each non CA member prior to the start of the player's first event in the Domain.
For all qualifying games, a player's index increases by 10 for each win and decreases by 10 for each loss.
Full bisque, advanced-handicap and bisque-difference games are treated the same way by the AHS.
The change to a players index depends on the number of steps difference between him and his opponent. The index change is calculated from table 1 for ALL games. A step is two bisques from handicap 12 upwards, one bisque between handicaps 5 and 12, half a bisque between handicaps 0 and 4½. For minus handicaps table 2 is used to calculate steps difference. These rules apply to both ordinary level and level advanced games.
Example 1: Roy (handicap 3) and Bab (handicap 14) play each other in a 26-point qualifying game. There are 12 steps difference between their handicaps. Thus, if Roy wins his index increases by 1 and Bab's index decreases by 1. However, if Bab wins her index increases by 19 and Roy's index decreases by 19.
Example 2: Roy (handicap -1½) and Bab (handicap 0) play each other in a 26-point qualifying game. There are 8 steps difference between their handicaps. Thus, if Roy wins his index increases by 3 and Bab's index decreases by 3. However, if Bab wins her index increases by 17 and Roy's index decreases by 17.
|Handicap Steps Difference||Index Change|
|Higher Handicap Wins||Lower Handicap Wins|
|7 or 8||17||3|
|9 or 10||18||2|
|11 or more||19||1|
|Handicap||0 to -½||-½ to -1||-1 to -1½||-1½ to -2||-2 to -2½||-2½ to -3|
Whenever a player's index is on or past a trigger point for a handicap change [see Table 4] his handicap changes accordingly at the end of that day except that all games within an event should be played off the same handicap. However, note Regulation H1(a), which states that for tournaments that run over several weeks, such as the Longman Cup or Mary Rose, each round shall count as a separate tournament for the purposes of triggering a handicap change.
If a tournament (other than at a CA Calendar Fixture) lasts no more than four days then a handicap change can only be triggered at the end of the Tournament.
Within a CA Calendar Fixture, if one event is played to a finish before a separate event is started then a handicap change can be triggered at the end of the first event. However, if several events overlap a handicap change can only be triggered at the end of the Tournament.
CA members are required to change their handicaps on the members' area of the CA website - the CA Office is no longer responsible for this. Players who do not have the means to do this should contact their club secretary.
|-2 ½||2800||2 ½||1750||10||1250|
|-1 ½||2400||3 ½||1650||12||1150|
|- ½||2100||4 ½||1550||16||1050|
All players who compete in qualifying games are required to record their results on an official handicap card. Players should bring their handicap cards to all tournaments in which they play. See the example for an illustration of how to complete a handicap card.
Table 5 summarises the information presented in the handicap system description and provides a simple look-up for all level games: the intersection of the winner's and loser's handicaps, shows the number of index points that change hands.
David Harrison-Wood has also produced a single-page guide to the AHS that can be kept alongside your handicap card.
