Club Rating Systems

Create your own in-club chess rating system

Give your club a rating list that reflects the games members actually play: blitz nights, rapid quads, scholastic sections, ladder challenges, and standalone club games without treating every result like an official federation event.

Create separate club rating pools for blitz, rapid, scholastic groups, or recurring club formats
Use a game ledger so ratings can be audited, removed, reattached, and recomputed
Let organizers approve standalone submissions before they affect published standings
Publish a leaderboard that gives casual club games more continuity between events
What a club rating system needs
Live board
A defined pool

Keep blitz, rapid, classical, scholastic, and special-event lists separate so the numbers stay meaningful.

A game ledger

Store each rated game, result, source, approval status, and rating application instead of only storing the current number.

Organizer controls

Let admins set starting ratings, approve submitted games, remove mistaken applications, and recompute from the ledger.

Chess67 club ratings are designed for in-house standings, not as a replacement for official US Chess or FIDE rating reports.

Planning

Start with the rating pool, not the formula

The biggest mistake is mixing unlike games into one list. A club blitz night and a slow classical section measure different skills, so the best in-house systems keep clear pools and rules.

Separate time controls

Create different lists for blitz, rapid, classical, scholastic, or casual ladder play when the player pool or format changes.

Write simple rules

Define what counts: both players must be club members, byes do not count, and forfeits should be treated consistently.

Choose a starting point

Use a default such as 1200 or 1500, then let organizers override known players who would otherwise distort early standings.

Keep approval clear

If members can submit their own games, require organizer approval before ratings update.

Track source context

Distinguish tournament games from standalone club games so members can understand where each rating change came from.

Make corrections reversible

Use a ledger-based model so an organizer can remove or reattach one rating from a game without losing the game itself.

Algorithms

Elo, Glicko, and Glicko-2 solve different organizer problems

Elo is easy to explain: expected score plus a K-factor adjustment. Glicko adds rating deviation, which says how certain the system is. Glicko-2 adds volatility, which helps model players whose results are less stable.

Elo

Best when you want a transparent club rating that members can understand quickly. It is simple, familiar, and good for casual internal lists.

Glicko

Useful when players have uneven activity. Rating deviation lets newer or inactive players move faster until the system has more evidence.

Glicko-2

A stronger fit for online-style pools or active clubs because volatility can account for inconsistent performance over time.

Display one number

A polished club page should show one chosen rating while the system can still calculate the other models behind the scenes.

Operating Rules

Practical rules for a trustworthy in-house leaderboard

The math matters, but the policy matters more. Members will trust the rating list when the rules are visible and mistakes can be corrected.

Only rate games where both players belong to the club rating pool.
Keep tournament section rating attachments separate from the tournament as a whole.
Require approval for member-submitted standalone games until the club is comfortable opening submission permissions.
Show game history, rating status, and whether a rating was removed from a game.
Let organizers attach or remove a rating application without deleting the underlying game record.
Recompute from the earliest changed game when corrections happen, instead of manually editing current ratings.

Build the club surface around the rating list

An internal rating system works best when it is connected to members, tournaments, and public club pages.
