The Candidates Tournaments occupy a central place in the chess calendar, as it determines the challengers for the next World Chess Championships - in the open and women's circuits.
With only a small, elite field competing over a demanding round-robin format, every encounter carries considerable weight, and familiarity between players often plays a role. Examining head-to-head records offers a useful way to contextualise these rivalries ahead of such a decisive event.
The focus here is placed on the direct records between participants, highlighting how individual matchups have developed over time. These statistics can reveal patterns that are not immediately apparent from ratings or recent form alone.
To compile these figures efficiently, the data has been sourced using Mega Database 2026, the leading reference tool for players of all levels. With over 11.7 million games spanning from 1475 to 2026 and more than 114,000 annotated encounters, it offers a comprehensive and reliable foundation for statistical work of this kind.
In each pairing, stats have been separated in 1) classical encounters and 2) all encounters, which include rapid, blitz and chess960 games, played over the board or online.
