The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Notable, but primarily known within a niche. The tier summarizes documented career recognition through the data cutoff—not Ivan Sokolov's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.

No current annotation distinguishes self-built, enabled, or earned origins for this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Ivan Sokolov's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born in Jajce, Bosnia and Herzegovina, Yugoslavia; father was an amateur chess player who taught him the game at age 6. Family financial background not documented in reviewed sources.
His father was an amateur chess player who introduced him to the game, providing initial domain exposure but not professional-level expertise or networks.
Sokolov learned chess from his amateur-player father at age 6 and joined Chess Club Bosna in Sarajevo, where he remained a member for nearly thirty years. His father provided initial domain exposure but the family had no documented professional chess connections or financial resources. His rapid rise from FM to GM in two years (1985-1987), becoming the youngest GM in the world at 19, reflects exceptional talent and intensive self-directed study. The Yugoslav chess ecosystem and Chess Club Bosna provided a competitive training environment.
