How to read this record

These are results, not ratings. We publish wins, losses, draws and every move — we do not assign Claude a chess rating or claim it is stronger or weaker than any other model, because a few dozen games between two players cannot establish that. On a missed 30-second shot clock the move falls back to an engine instead of a forfeit; those moves are marked ⚙️ on the game page and are never quoted as the model's own. The site-wide engine-assist rate is published on the stats page.

The opponent lists above add up to 86 games rather than 87: 1 game shares a date-and-show key with another game and so cannot have its own archive page. The 87-game record is the complete one.
