Pairs event movement types

Previous pageReturn to chapter overviewNext page

 

This field determines the type of movement you are using in this section. Consult your tournament directing books for details on each movement type used, or see "Bridge Directing Complete".

 

A list of the movement types available are shown below together with the checks that the ASE Scorer places on these movements.

 

Howell

This does not include the ¾ Howell which has a separate entry. The actual Howell movement used is determined by your selection on the next screen. Only the movements that satisfy the criteria on the section details screen are shown in the list.

 

The Howell movements are defined from the main menu item [Movements]. The non-standard Movements need to be defined prior to their use. There are Howell movements supplied with the scorer and you may add your favourites.

 

The Howell movement requires the number of winners to be 1. If you have specified two winners you will be need to change it to 1 before proceeding.

 

Where the number of tables includes a half table, the Howell movement used is for the next highest number of whole tables. For example, with a four and a half table section you would use a five table Howell movement.

 

¾ Howell

Procedures with ¾ Howell movements are the same as for standard Howell movements. The difference between the Howell and ¾ Howell is the number of rounds played. In the ¾ Howell the number of rounds must be less than in the standard Howell.

 

When you click [Next], a list of ¾ Howells that satisfy the values (number of tables and rounds) are shown for you to choose the movement in use.

 

Mitchell

The Mitchell movement only applies where the number of tables is odd. The session may have 1 (one) or 2 (two) winners. With an even number of tables the system uses the default movement (skip or share and relay Mitchell movement).

 

When a Mitchell movement is selected with one winner an additional field is enabled to select "Switched". This allows you to use a switched Mitchell, with the switch rounds being entered on the same screen.

 

Skip Mitchell

You may use the Skip Mitchell when the number of tables is even. After pressing [Next] you are able to enter the round when the Skip occurs.

 

Relay Mitchell

You may use the Share and Relay Mitchell when the number of tables is even. After pressing [Next] you are able to enter the position where the relay table occurs.

 

Whist Mitchell

The Whist Mitchell movement is only useful where the number of tables is odd. The session may have 1 (one) or 2 (two) winners. With an even number of tables the North-South pairs play the same East-West pairs after half way.

 

Appendix Mitchell

The Appendix Mitchell (Beynon Appendix Mitchell) appends a number of tables onto a base Mitchell movement with a prime number of tables. The number of board sets specified on this panel dictates the size of the base. e.g. with a 17 table section and 13 sets of boards the movement is a 13 table (base) Mitchell with 4 appendix tables.

 

One and one half table Appendix Mitchell

This movement requires that the number of tables in the section includes a half table and that the number of tables is a valid number for this movement. The skip Mitchell is used where the base includes an even number of tables (e.g 11.5 Tables uses a 10 table base and so a skip occurs after 5 rounds).

 

North South Rover Mitchell

This requires that the number of tables includes a half table. The half table number must be equal to one more than the whole number of tables, the last table number. For example a 7.5 table movement is defined as having 8 tables, E-W missing at the last table, number 8.

 

The ASE Scorer Version 9 checks that the number of whole tables are not be divisible by three or equal to twenty five. These are not valid movements.

 

This movement requires that the N-S pairs are stationary.

 

Where the number of whole tables is an even number, (for example, 10.5 tables) you will be shown the round where the skip will occur, and this is fixed.

 

There are special N-S Rover Mitchell movements available for numbers of tables divisible by three. For example, 9 ½ tables. These are not valid with this movement type. If you require such a movement you will need to generate the movement using the USER type movement.

 

Usually the N-S Rover Mitchell proceeds with the North-South Rover pair replacing the pair at N-S table 2 on the second round. You are given the opportunity to change this value.

 

When the number of whole tables is even (eg. 14.5 tables) after the skip round the N-S pair replaced by the Rover pair is the next higher pair from the first pair replaced. e.g. where the N-S Rover replaces N-S 2 on round 2, next higher is the pair at table 3.

 

Web Mitchell

This movement requires the total number of tables be even. Therefore 15½ tables is considered an even number. The number of rounds and board sets should be equal and may be an even or odd number. Where the number of board sets is even you will be required to skip at some point in the movement. You are shown the round number after which the skip occurs.

 

User defined movement

You specify this movement type only when you require a movement that is not available in the standard set. To use this type you must define the complete movement round by round, table by table using the user movement option.

 

Once you have defined the movement you may use it any number of times. The definition is only required once. Having defined the movement you may choose to vary the other parameters on this screen.

You may have a different number of boards per set, a different board set on table one in round one, non-default pair numbers or you could use the movement as a barometer where the boards are shared across the field.

 

Note: the difference in the terms movement and section. A movement is used to define a section.
