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.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Richard Krajicek'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.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Richard Krajicek'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 Rotterdam to Czech immigrant parents; his father Petr put a tennis racket in his hand at age four and insisted on practice, providing early domain exposure and motivation.
Not documented.
Krajicek benefited from his father's early introduction to tennis at age four and the Dutch Tennis Federation's elite coaching pipeline under Stanley Franker, who provided sustained, structured training. He dominated Dutch junior tennis, winning national championships at under-12 and under-14 levels. The Federation's systematic approach—satellite and challenger circuits, specialized coaches like Rohan Goetzke—concentrated opportunity for top juniors. His Czech immigrant family provided a sport-oriented household, though not exceptional wealth.
