Candidates R1: Head-to-head stats

by Carlos Alberto Colodro
3/29/2026 – Head-to-head records between the participants of the Candidates Tournaments provide useful context for each pairing. Drawing on data compiled via Mega Database 2026, the key statistics from past encounters highlight imbalances and trends. While such figures are not decisive, they offer an additional perspective on how rivalries have developed before a tournament that will determine the next challenger for the world title.

Your personal chess trainer. Your toughest opponent. Your strongest ally.
FRITZ 20 is more than just a chess engine – it is a training revolution for ambitious players and professionals. Whether you are taking your first steps into the world of serious chess training, or already playing at tournament level, FRITZ 20 will help you train more efficiently, intelligently and individually than ever before. 

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.
