Teams from the same squad playing each other first is correct in principle. Leagues are wise to insist on it.

But I have never suspected any kind of collusion in the time I've played in the 4NCL, certainly not in Div 3N; and not in Div 1 or Div 2 either. Those with greater experience may have other tales to tell. So I don't think it's a problem that needs fixing. Indeed, why should intra-squad collusion be any more likely than intra-national collusion (between, say, Gonzaga and Enniscorthy); or intra-Yorkshire collusion (between, say, Bradford and Jorvik)? Indeed, with bragging rights at stake, I'd bet MM1 v. MM2 or Brad1 v. Brad2 are every bit as fiercely fought as any other match-up, even under promotion conditions

That sort of happens in the pool system.

In Divisions 1, 2 and 3 South, you can't have more than two teams from the same squad in the division. So they are seeded such that they start in different pools. Should they qualify for the c or d pool, they play each other in Round 8, i.e. the first round of the new pool.

It is a rule for divisions that aren't Swisses. (Specifically, when the divisions were 12-team all-play-alls, teams from the same squad always met in the first weekend. In the 16-team pools, they must start out in separate pools, and then if they end up in the same championship/demotion pool, they must play in round 8.) I suppose you could institute it as a rule for the Swisses, but it could lead to unwanted consequences, particularly when a team has more than two teams in the same Swiss division.

There are 11 rounds with 20 teams, so each team misses 8 of the others; ideally, that would mean no clashes within squads, although I can see that a meeting between Manticores teams may prove necessary

It is missing the point of why players enter, and why squads enter more than 1 team, to insist they play each other in weekend 1 :roll:

Players compete in the 4NCL to play competitive chess without the strictures of the three hour maximum time allowed for an evening League game.

I would not want to find I have a 200 mile round trip to Bolton to play against the club colleague who sits next to me in the evening league a dozen times a year and lives ten minutes drive away.

Alex McFarlane has posted this 'explanatory' note to Team Captains. It provides guidance and 'illumination' on the Div 3N pairing arrangements: criteria therefor, principles thereof, exceptions therewith, and lump it therefore.

I'd like to find fault with it, just to amuse myself. But instead, I'll offer a prize to anyone who can explain what Alex is on about. To be honest, I think he's being helpful. But with Arbiters, you can never be too careful :wink:

_______________________________________________

Pairing System for 4NCL (3N)

It was agreed that various suggestions would not work. Mini leagues would fail if teams defaulted meaning triangular matches needed. Triangular matches are awkward enough but if they were to affect more than one mini-league then the problems caused would be magnified. It was considered that the risks of defaults were not insignificant and it was therefore not worth ‘taking a risk’.

It was agreed that a straight Swiss would result in the top teams playing each other sooner than was desirable with the potential for the promotion places to be decided well before the final weekend. It should be recorded that feedback from teams indicated that they wanted the final weekend to be significant in deciding promotion and that this was not just an organisers’ viewpoint. It was therefore decided to look at alternative ways of delaying the top teams meeting.

Dividing into groups by seeding was considered. Having 4 groups was considered the best option. Group A would be the top 25%, Group B would be the next 25% and so on. If the number of entries did not divide by 4 then the extra teams would be put in Groups B and C. (Triangular matches if required would be 2 teams from Group C and 1 from D if possible.)

Rd1 Group A wound be paired against Group C, Group B v Group D Group B v Group C for any remaining teams.
Rd2 Group A v Group B, Group C v Group D

This pairing system would be used for the first 3 weekends and the option of doing so on weekend 4 would be kept as a possibility. (A fourth weekend would ensure the top teams playing in the final weekend but if there was a lot of bunching for the second promotion spot then it might prevent sufficient remaining rounds to ‘sort out’ the true second best team.) If at the end of weekend 3 there were 9 or more teams within 2 points of a promotion spot then it is advisable to pair these teams together in weekend 4 (rd7) and therefore abandon the avoidance pairings. If there are only 4 or 5 teams fighting for promotion then continuing the pairing system for an extra round (or possibly 2) is acceptable.

For the remaining rounds a straight Swiss would be used.

This procedure should ensure that the top teams are kept apart for as long as possible. The only potential problem could arise if the initial seeding is not accurate.

In Div3N last season the seedings were changed after weekend 1. In theory this seemed fine but did not work well in practice as one of the top teams had been weak on the first weekend and were seeded down to play the other top teams earlier than desired. Some tweaking of the quartiles may be necessary but should only be done with caution and with the amount of movement limited to a few places downwards. An unexpectedly strong team may be moved up.

It looks very sensible and quite clever. Basically it is a decelerated pairing system (opposite of accelerated pairings).

Instead of trying to get the stronger players / teams playing each other early (accelerated pairings), by pretending the stronger players / teams have more points to start with, he is using the 4 quartiles to keep them apart longer.

Seems very sensible to me too. The quantiles are obviously also there to keep the field each team faces vaguely balanced.
