Club Champ Rules 2020-21

TCC Club Championship – 2020-21

This is based on the original invitation, but has been amended to include the changes made on 28 Sept 2020 and also for display on the Website.

Club Championship Rules

A Swiss tournament – default timing 75 + 10 secs, games to be played to on lichess (or chess.com or even face to face by agreement). Although games will be played on lichess it will not be a lichess tournament, the draw and organisation will be done by controller (TW).

We may reconsider this format, depending on the number of entries.

White is expected to challenge Black.

Roughly one game per month (Dec 24th & 31st look unlikely, Easter Sunday is Apr 4th).

As this is a Swiss tournament, strict adherence to “end of round” dates is important. A schedule of suggested match dates will be issued. Games can be rescheduled and do not have to happen on a Thursday night. If a game is re-scheduled the controller (TW) must be informed. If a game has not been re-scheduled and there is no evidence to suggest an alternative date was arranged, then both parties will be deemed to have lost.

Alternate Thursdays will be allocated at the club for long play games (in yellow below). It is expected that Club Championship games will happen on these yellow dates, but that is not a strict rule. Scheduled round start dates are marked S, end of round dates are marked E.

The following changes were made on 28 Sep 2020

The format has changed because with 12 entries, 7 rounds is too many, a swiss tournament will lose it’s meaning after 4/5 rounds with only 12 players, so 5 rounds.

There will be an end of tournament knock out for the top 4 finishers, the club championship awarded to the winner of the knock out.

I need to investigate arrangements for players who tie with equal points, some kind of count back depending on performance of who you have played.

Games subject to internet breakdown will be adjucated by controller if either side requests it.

Timing can be amended if both sides agree.

A ½ point bye is available for late entries, up to the start of the second round.

The draw is made using Sevilla software and gradings are ignored for the draw.

This is a table of Thursdays

Grading Prize

A grading prize will be awarded based on a player’s performance against their own ECF grade. Players with the highest grades will not be eligible- e.g. if there are 11 players- the top 5 are not eligible.

I will calculate the performance in each game- and then average these over the competition.

The method used will be based on my understanding of the ECF grading system- which is included below.

There is no intention to use the Fide / ELO grading system.

Tim’s understanding of ECF grades.

Normally If you beat someone your performance is rated as your opponent’s grade + 50. But if you play someone who is graded more than about 40 points below you this can become nonsense, so the difference is capped at 40 points, and you are awarded a performance 10 points above your own grade.

A couple of examples.

1. You are graded 120, your opponent 100

If you win, your performance is rated at 150 (100 + 50) . Your opponent’s performance is 70 (120 – 50)

If you draw, your performance is rated at 100 (100 + 0) . Your opponent’s performance is 120 (120 + 0)

If you lose, your performance is rated at 50 (100 – 50) . Your opponent’s performance is 170 (120 + 50)

2. You are graded 120, your opponent 60.

If you win, then for the purpose of this calculation their grade is taken as 80 and your performance is rated at 130 (ie 80 + 50). Your opponent’s calculation is similar, their grade is 60, your grade is taken as 100, and their performance is 50 (100 – 50)

If you draw, then for the purpose of this calculation their grade is taken as 80 and your performance is rated at 80 (ie 80 + 0). Your opponent’s calculation is similar, their grade is 60, your grade is taken as 100, and their performance is 100 (100 + 0)

If you lose, then for the purpose of this calculation their grade is taken as 80 and your performance is rated at 30 (ie 80 – 50). Your opponent’s calculation is similar, their grade is 60, your grade is taken as 100, and their performance is 150 (100 + 50)
