Individual movement

[kgr]

Our club will organize an individual tournement for their memebers.

There are 40 subscriptions until now (this will probably be the final number of participants).

For this tournament we have about 4 or 4.5 hours (is around 28 boards?)

The games will not be predealt because we don't have the facilities for that and everybody wants to play.

The participants are not all of the same level, but we also don't want to loose too much time with moving.

Preferably the movement should be self-explaining so that we don't have to make movement cards.

Does anybody have a good proposal for this movement?

 

Thanks!

I'm no expert on movements, however, I'm pretty sure that you can't create fair movements using an artibrary number of tables...

 

However, you do appear to be in luck. There are good individual movements available for both 9 and 13 players.

 

Were it me, I'd run three sections of 9 players using

Add on one section of 13 documented at

and you're good to go. Its important to note that you'll have no comparison between sections. However, the comparisons within sections are optimal....

 

You will need movement cards, however, thats to be expected with any individual

Richard, haven't you played in the Newton Individual Regional? They use a Mitchell-like movement, something like South goes down 1, East down 2, West up 2, with a couple of EW skip rounds in the middle.

 

This has the misfeature that you only partner with 1/4 of the players (i.e. if you're South you'll partner only with all the North players), but it's much less confusing than any movements that achieve that. Lots of these involve rotating the S/E/W players between each board in a round, and even experienced players seem to screw this up (rotating the wrong way, forgetting to rotate).

 

BTW, questions like this really belong in Offline Bridge forum. What does it have to do with BBO Tournaments?

Degenerate movements of the sort used in Newton really aren't germane to the question at hand. Case in point: Its trivial to design an individual movement for 40 players playing N boards. Set up 10 tables. Have them play N board without moving. The Newton example isn't quite this bad, however, it still isn't really applicable.

 

The Newton movement only works because of the ridiculous number of participants. In order to run the same "fake mitchell" with 40 players, you'd need to play a LOT of boards each round. Please note that you "only" have 10 tables. Your also stuck with an even number of tables so you can interleave the pairs when then switch from top of the row to the bottom. Thus, the Newton type movement only allows 5 round changes...

 

In short, simplicity may be a virtue but its not without its costs...

This movement is called a Rainbow movement, and it is the standard movement in all large individual events. Just as in a Mitchell movement, none of the N/S pairs play another N/S pair, in an individual movement, Norths only compete in their section against other Norths, South vs. South, etc. I don't recall the details of how to run a rainbow movement, but I believe they require a prime number of tables to work most smoothly. If each table plays 3 boards a round, the players can rotate around north so that each partnership at the table is played for 1 hand.
