The chess systems.
Gameplay
Legal moves
Server-authoritative validation keeps every move, draw, resignation, and timeout outcome inside real chess rules.
Notation
FEN • UCI • SAN
The platform keeps board state technical under the hood while still rendering moves in a way players can read.
Tournaments
Standings first
MVP round robin ends with final standings, not a generated playoff bracket.
Standings
Trace ties
`tieBreakerTrace` explains how equal scores separate instead of leaving ranks feeling arbitrary.
Gameplay features
Chezzai keeps the core match loop familiar while adding tournament structure, review surfaces, and profile systems designed specifically for chess players.
Authoritative rules
Server-authoritative legal move validation, draw offer and acceptance, resignation, and timeout result handling.
Board state language
FEN-based board persistence, UCI move input, and SAN move display keep game state technical and readable at the same time.
Post-game intelligence
Stockfish analysis, AI game summaries, and thinking-pattern analysis help players understand what actually happened.
chess-native terms
Use chess-native terms everywhere the product speaks.
FEN
Board position string used to persist and restore a game state.
UCI
Machine-friendly move notation such as `e2e4`.
SAN
Human-readable move notation such as `Nf3`.
White / Black
White moves first and Black moves second.
Check / Checkmate
King under attack, or legal game-ending mate.
Stalemate / Draw
Valid chess draw outcomes, not generic score labels.
Resignation / Timeout
A conceded game or a loss on clock.
Bye / Match points
Tournament-specific terms for odd rounds and standings scoring.
Avoid football-style naming
Avoid `goalsFor`, `goalsAgainst`, and `goalDifference` when describing chess standings or score breakdowns.
Preferred field names
Use `pointsFor`, `pointsAgainst`, and `pointDifferential` when a neutral differential field is still needed.
Round-robin MVP
The tournament model focuses on readable round-robin structure first, with clean defaults for standings, completion, and progression.
Every participant plays every other participant once.
The tournament completes when all round-robin matches are final.
Final standings decide the winner for the MVP format.
No playoff or single-elimination bracket is generated after MVP round robin.
`playoffFormat` stays `none` and `advanceTopCount` stays `0` for MVP.

chess guardrails
Tournament rules should stay configurable without making the structure hard to read. These defaults keep scoring and tie-break logic explicit for both players and organizers.
Point System
Tie-Breaker Order
Use an explicit point system so wins, draws, forfeits, and byes remain easy to audit across every event format.

Clear Standings
Standings should explain themselves. Chezzai keeps every ranking field visible, traceable, and aligned with chess terminology.
22
Ranking fields can stay compact without hiding meaning.
Trace
Every table movement should be explainable after each round.
One model
A single standings model keeps players, admins, and reviews in sync.
