Scope: four long-running elite classical series — Linares, London Chess Classic, Norway Chess and the Sinquefield Cup — covering 51 tournament editions from 2000 through completed 2026 events: 54 winner credits across 18 players. “Major” has no official definition; this is a reproducible panel, not every elite event (Tata Steel, Dortmund, Candidates and World Championships are not included in this pass, and London lists no 2020–2022 editions). A winner credit is one credit for appearing as an official winner, shared titles included; a fractional title divides one title equally among co-winners.

Rapid/blitz, women-only and lower sections excluded; Tata Steel, Dortmund, Candidates and World Championship omitted in this pass; London 2020–2022 not listed by its source.
