They did allow half-point byes when I was there. They also used an accelerated pairing system for several rounds.

It's good to see a representative of our own dear Channel Islands also.

Of the four players from my 4ncl teams three (Jonah Willow, Irene Sukandar, Ben Larkin) are playing English players whilst the fourth (Diana Mirza) is playing a former English player (having just drawn with Nigel Povah).

Does anyone know how long the accelerated pairings last?

Until there's a single tournament leader.

If it's a Baku, I thought the fide rule state that for a 9 round tournament, there are 3 rounds with 1 point acceleration and 2 rounds with 0.5 point acceleration.


Edit: found the rule:
The "accelerated rounds" are the ones in the first half (rounded up) of the tournament.
Before pairing the first half (rounded up) of the accelerated rounds, all the players in GA are assigned a number of points (called virtual points) equal to 1.

Such virtual points are reduced to 0.5 before pairing the remaining accelerated rounds.
Note:
Consequently, no virtual points are ever given to players in GB, or to any player after the last accelerated round has been played.


Example:

In a nine-round tournament, the accelerated rounds are five. The players in GA are assigned one virtual point in the first three rounds, and half virtual point in the next two rounds.

So more than half of the tournament is screwed up. To what purpose?

I think it was 4 or 5 rounds when I played. I assume the idea is to avoid the Swiss bounce, whereby you lose to a 2700 in round 1, then get a 700 in Round 2. Whether that is a good idea or not, I don't know...

Theo appears to be having a limited version of this, though hopefully he can avoid losing today

Good to see Chris Rice doing well

If so, it isn't working very well.

Theo Khoury's opponents have gone 1652, 2422, 1652, 2373.

It works much better for players in the top quarter if you look at their opponents.

I think some experienced arbiters commented on other threads about the pros and cons of acceleration.

Ah, so it's for their benefit. That has not been properly explained.

Advocates of acceleration have long claimed that it improved Norm chances by increasing the strengh of opposition. That would likely apply to players in the second quarter ias well if they are able to overturn the ratings verdict and win in the first and second rounds.

Acceleration has been less popular in the UK since the Baku system was devised. It removed an excuse for using manual pairings given that the pairing software can be hacked to pair players not of the same score.

I rather doubt that a GM in the top quarter of the draw who hopes to win the tournament, or at least finish in the prize money, and who has no interest in norms, would regard playing stronger players than they would have done in a normal draw as a benefit.

Followed by a 1565 unfortunately.
