Handicapping in Croquet
"Over a period of time players have learnt that the result of a single game between high bisquers in Short Croquet is largely dependent on who wins the toss. In effect the number of bisques is too high and favours 'last in'. " To make handicap games less onesided the number or distribution of the bisques can be changed or extra manoeuvres added to allow each player the opportunity to ‘get in’ and have a chance of winning. This is especially the case in shortened games where each ball makes 6hoops then pegs out, whether on a fullsize or near halfsize lawn. Players may have the ability to make 6hoop breaks but not 12hoop ones hence the number of bisques needs to be modified for these shortened games to even up the odds. Firstly to review the various handicapping systems. Handicap SystemsCurrently there are two systems of handicap play (see also pages in the coaching section):
There are then additional modifications to accommodate reduced games (e.g. short or 14points games) or full games where the number of bisques is reduced, generally to prevent one player whitewashing their opponent by using all their bisques to take their balls around in two turns. Subtractive and Multiplicative ModificationsThe two main modifications are multiplicative and subtractive. For example applying a multiplicative factor:
In Full Bisque games there are combinations of subtraction and a factoring:
ExamplesBelow, a base of 3 is used and a factor of 1/3. The columns show the number of bisques received by 12 and 24handicap players in a match. If a fraction of a bisque results at the end of the calculation, it is rounded up to the nearest half or full bisque.
Other ManoeuvresSo far the only compulsorily manoeuvre which has been adopted to balance the levels of ability of strong players playing weaker ones is mandatory peels (causing a ball to run its hoop by striking it with another ball) in Short Croquet (a designated form of croquet played on a small lawn). This introduces an extra level of complexity to prevent a good player speeding around. The first challenge however is to find the table of mandatory peels on the CA web site … Time limits are not advantageous to good players as all of the time in the game is consumed by the high bisquer spending their bisques. Whilst other tricks can be thought of none have been adopted to date. As a suggestion a system could be based on a staggered start; the weaker player's clips are placed on, for example, hoops 2 & 3 at the start of the game. Options for Handicapping in Short Croquet"Rather than play bestofthree, we are going to introduce some version of fullbisque play which is less 'trivial', but still worthwhile on a small lawn. For simplicity, I favour using a fixed base (say 8) for a 26pt game, with 2 hour limit. We also play 'normal' croquet on full lawns! What would you think is a good system to improve 'short croquet' on using half lawns?
You make a number of suggestions for alterations. Reduced Time LimitsI would be against reducing time limits as this favours the high bisquers. In a normal handicap game, once the high bisquer has used all of their bisque turns and failed to reach the peg, the low bisquer gets their chance to hit in and make hoops. The following scenario is all too common; the 'burning of the bisques' has taken 3 hrs 7 minutes leaving 8 minutes for the better player to get their first ball around and hope for an innings change. Time limits are bad. Short Croquet has the benefit that there are few hoops to make (its 14point) and the lawn is small so the route is shorter. To make games take less time consider advancing the clips of the weaker player with a consequent reduction in bisques. Use a variable base system on full size lawns to ensure that "high bisquer  high bisquer" games are well supplied with bisques but "low bisquer  low bisquer" games remain competitive. Large Lawn verses Short LawnFor a smaller court the handicaps would need scaling to allow for high bisquers making further progress than they would because of the proximity of the hoops. This may well have been taken into account in the tables which transliterate between normal handicaps and Short Croquet handicaps. Using a Variable Base SystemIf the intention is to use a Variable Base System with Short Croquet, a problem arises with the YVBS in that as the handicaps are first scaled for the smaller lawn and then scaled for the variable base, the results are going to be small numbers which will round up to similar numbers. The YVBS base would be obtained by: (H1 + H2)/4 * factor for 14point * factor for small lawn. There seem to be a number of conflicting or unavailable figures.The Laws have a table for translation between 24point game handicap and 14point games which offers a factor of 11/20 (0.55). I feel sure Kevin Carter's factor is smaller (0.33?). Next the factor for the small lawn could be, hopefully, derived from the Short Handicap tables, which are unavailable currently. For a guess let's use 1/2 for the lawn factor and call the 14point factor also 1/2; this yields (H1 + H2)/16 for the YVBS. Try some numbers; say a
This does not look useful. 26point GameIf the game becomes 26point then it would no longer be formally Short Croquet, but Association Croquet on a reduced lawn. This would then eliminate mandatory peels, etc. unless you define it otherwise. Increasing the number of hoops would introduce more changes of innings/bisque consumption. Novices cannot make 12hoop breaks but could make 46 hoop breaks. It is not easy to predict how this would affect the handicaps or vice versa. All I can suggest is a trial. SuggestionsIf you will be using small courts and similar ability players then, to remove the whitewash factor (the winner of the toss winning the game), introduce a moderate fixed base. This will cause the players to have to make hoops without bisques. It has the advantage that it is easy to calculate. If you have a wide range of handicaps then this is unsatifactory. If you are playing on a full size court then the a Variable Base system will work well. If you want to make the players 'work' by having a lean number of bisques then you could produce the base by dividing by a smaller number than four: e.g. (H1 + H2)/3. I would not recommend Time Limits, as I do not think that they are fair when a large number of bisques are available. A slow player with a mountain of bisques will deny their opponent the minutes necessary to gain a victory. The staggered start method has not been tried to my knowledge so there is scope for some thought there. All rights reserved © 20042017
