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.
These stats do not include the results from the games played during the first half of the Candidates Tournaments.

EXPAND YOUR CHESS HORIZONS
Data, plans, practice – the new Opening Report In ChessBase there are always attempts to show the typical plans of an opening variation. In the age of engines, chess is much more concrete than previously thought. But amateurs in particular love openings with clear plans, see the London System. In ChessBase ’26, three functions deal with the display of plans. The new opening report examines which piece moves or pawn advances are significant for each important variation. In the reference search you can now see on the board where the pieces usually go. If you start the new Monte Carlo analysis, the board also shows the most common figure paths.
