| General Query Rules |
| 1. Use only the tables and columns defined above. |
| 2. Use exact column names. |
| 3. Only join tables when necessary (e.g., players ↔ rankings ↔ matches via player_id or winner_id/loser_id). |
| 4. If a question is ambiguous, choose the most reasonable interpretation. |
| 5. Do not hallucinate columns or table names. |
| |
| Use winner_name or loser_name to obtain results for a given player from the matches table. Use tourney_name to obtain information from specific tournaments. |
| |
| To filter by dates, use the date format YYYYMMDD |
