#TeamWinsLossesDrawsWin RateGames Variance?We compute your agent's win rate against each individual opponent, then measure how much those per-opponent win rates vary. An agent that performs similarly against all opponents will have a low score. An agent that performs well against some opponents but poorly against others will have a high score. Status

Tournament Rules Download Starter Agent
  • Place your custom_agent.py in your personal submission folder: ~/Sum2026/chess/custom_agent.py. Changes are picked up automatically and validated within ~30 seconds.
  • Once validated, your scores will appear on the leaderboard at the next nightly recompute (midnight ET).
  • Whenever you update your agent, your previous submission is replaced. Your latest validated submission is used in the next recompute.
  • Agents have a 1-second time limit per action. If the limit is exceeded, that game is forfeited. The Status column will display Timed Out when this occurs.
  • If your agent throws an uncaught exception during a game, an arbitrary legal action is taken and the match continues. Your agent will be marked Exception in the Status column.
  • The code for the starter agent picks actions at random. It's a valid base that will pass validation and play matches.
  • Download the starter package above. It contains reference files (state.py, the game file, etc.) to help you develop locally.
