Change in systems ( 02:00:27 FriJan 17 2003 )

Our Australian Nationals have 20 board matches. Is it legal to change system during the match if you want to? (if so how often can you do it)....
Is this any law against it - or would it depend solely on any local regulations which are in force for the event? Does anyone know the NOT regulations that may prohibit this?

[In particular he would like to play:
First 10 boards -
2D=weak either major (6 card suit)
2H=5 card H weak
2S=5 cars S weak
Then from board 11if the match has gone OK
2D-2S 6 card weak two.
If the match hasn't gone well stay with the original structure.]

Certainly it is not a matter Law. Permitted systems are a matter for the sponsoring organisation, the ABF in your case.

I shall see if I can find out, though the person I would normally ask is unavailable at the moment! :sad:

Hi David,

I have registered now - yes it is harder to find out with all the directors now in Canberra. The relevant COCs are (AFAIK)
- the NOT
on the brochure - basically refers to the main ABF regs.
- and the ABF system regulations
There seems nothing specific (that I have found yet). The event COC refer to
the ABF system regulations which are available in full at:
http://www.abf.com.au/events/tournregs/sysregs.pdf

The only relevant bits seem to be:
(2.3)For all National (Gold Point) events, each pair shall have two
systemically identical system
cards on the table for the opposing pair before the start of play. This
practice is also recommended
for major Red Master Point events.
and
(10) CHANGE OF SYSTEMS:
No pair may play two different RED or YELLOW systems during the course of an
event
without the express permission of the Chief Tournament Director, unless
specifically provided
for in the Supplementary Regulations.

Which don't seem to prohibit this action.
Maybe (1) does but if you were to say:
Play system 1 for our first 10 boards, system 2 for our 2nd 10 boards then
it could all be on the prepared systems.

I am pretty sure that you cannot play 2 systems in the 1 match at the NOT unless you have registered this beforehand. eg it is legal to play lets say Moscito NV and Standard vul, but this has to be announced at the beginning of the match. You can't switch systems half way through a match just because you are getting crappy results. Check with McMannus just to make sure, but I am pretty sure I am right on this.

First, if you are permitted to change systems then it is imperative that you go armed with two sets of convention cards.

Second, I do not know what Ron Lel's authority for this is, and I am certainly not saying he is wrong, but it is interesting at least that the regulations you quote do not forbid this practice.

So I agree that the answer is to ask the DIC while you are there. Is that McManus now, not Mullanphy?
