Directors - movements for awkward numbers?

[zenbiddist]

Hi there,

 

I like to be ready for all sorts of awkward numbers, and these are the scenarios I'd like help with.

For each of these scenarios, the ideal solution would play 27 boards, and have as many stationary pairs as possible, and be the best compromise between simplicity/balance.

Thanks!

 

4.5T - is there something simpler than a 9x3 Howell?

5.5T - EDIT: 8x3 Double Hesitation allows for four stationary North-Souths (message me for the Compscore template).

6.5T - EDIT: 9x3 Double Hesitation (message me for the Compscore template).

7.5T - is there something better than a 10x3 Blackpool (cut short) or hesitation?

 

Cheers!

 

Ps: does anyone have the .CSV files for the movements? I don't have the templates in a form recognised by Compscore, which is what I need.

4.5T - is there something simpler than a 9x3 Howell?

5.5T - is there something better than a standard ¾ Howell movement (9x3) with 3 stationary pairs?

6.5T - is there something better than an 8x3 hesitation? 27 boards would be ideal.

7.5T - is there something better than a 10x3 Blackpool (cut short) or hesitation?

 

Cheers!

Within the parameters you've given, you don't have a lot of scope for variation. For 7.5 tables you would be better with the Hesitation Mitchell than the Blackpool. For 6.5 tables you have the option of a Full Howell - it only has 26 boards and it only has one stationary table, but it has the great feature that everyone plays everyone else.

You can find movements for a number of small games at the MIT/DL Bridge Club website (we averaged about 6 tables in 2017).

...the ideal solution would play 27 boards, and have as many stationary pairs as possible...

 

4.5T - is there something simpler than a 9x3 Howell?

Not really given that it is 4.5 tables. For 5 full tables you could play a Mitchell (5x5) or a hesitation (6x4) or a double hesitation (7x4), but when there is a sit out 4 or 5 boards twiddling thumbs is not ideal.

 

5.5T - is there something better than a standard ¾ Howell movement (9x3) with 3 stationary pairs?

Again not really for similar reasons

 

6.5T - is there something better than an 8x3 hesitation? 27 boards would be ideal.

Double hesitation Mitchell for 9x3

 

7.5T - is there something better than a 10x3 Blackpool (cut short) or hesitation?

Nope - what is wrong with a hesitation? I wouldn't recommend the Blackpool for 7.5 tables as one pair will sit out twice.

With 6.5 tables, our club's usualy movement is Pete Matthews's H7RVR-S:

Bye-stand scrambled Mitchell; rover bumps both directions for 2

boards (NS 1-6 stationary, play 4 boards before EW change

tables); arrow switch for last 4 boards. Relay 3-4, bye-stand 6-

1, roving pair 13 starts 4NS after 2 boards.

Each round is 4 boards, but sit-outs are only half of the round.

 

However, we only play 24 boards, not 27.

Double hesitation Mitchell for 9x3

7T Double Hesitation - Thanks Nick. Do you have a movement plan for it?

7.5T Hesitation rather than Blackpool (because revenge sit-out) - excellent! I'd forgotten about that. Thanks

NAME: Double Hesitation Mitchell

 

SET OUT BOARDS:

9 sets

Two relays between Table 4 and Table 5

 

PAIR NUMBERS:

Other NS pairs take table number

EW pairs add 6 to table number

There is no pair 2

 

 

PAIR MOVEMENT:

Pairs 1 to 6 are stationary

Pairs 7 to 15 move round following circuit:

->EW1->EW2->...->EW6->EW7->NS2->NS7->EW1->

 

ARROW SWITCH:

On last round at Table 3

On last three rounds at Table 6

 

COMMENT:

This movement is inferior to the 26-board Howell;

Its great merit is that table cards can be dispensed with if the moving

pairs are instructed to write down their itinerary at the start of the

session.

 

I tried to put the table cards here but the spacing was all lost. Instead here is the EBUScore format movement - each line is a table containing NS, EW, Bd, NS, EW, Bd etc in round order.

PAIR NUMBERS:

Other NS pairs take table number

EW pairs add 6 to table number

There is no pair 2

 

 

Sure you've got that right Gordon? That means NS at T7 is pair 7 and EW at T1 is also pair 7!

No, if you are talking about the first round, NS at T7 is pair 2.
