The Top Chess Engine Championship (TCEC) is one of the most prestigious and long-standing competitions for evaluating the world's best chess engines. Founded in 2010, TCEC hosts seasonal tournaments where the strongest chess engines compete in various time control formats. The engines are ranked based on their performance, with the tournament typically divided into stages culminating in a superfinal.

TCEC has gained significant traction due to its highly competitive nature, the involvement of the world's most powerful chess engines, and the detailed analysis it provides. Its tournament structure usually involves several leagues, progressing through knockout stages to determine the strongest engines in the world. The competition operates in different modalities, including classical (longer time controls), rapid, and blitz formats.
TCEC Structure and Modalities
- Superfinal: The top two engines from the premier division compete in a long match format with multiple games.
- Premier Division: This division hosts the top-rated engines in a round-robin format.
- Leagues: Engines compete across several divisions (from 1 to 4), with the top engines advancing to higher divisions.
- TCEC Cup: A separate knockout-style tournament with faster time controls.
- Swiss Tournaments: Some seasons also include Swiss-system competitions.
Each modality tests the engines' strength under different time pressures and conditions, allowing developers to fine-tune their algorithms across a range of scenarios.
