Won silver in 400m IM at World Championships at 17 (2003); won bronze in 400m IM at Olympics at 18 (2004); won World Championship gold in 400m IM at 19 (2005); won three silver medals at 2008 Olympics behind Michael Phelps; became 33-time European Champion.
Born in Budapest, Hungary in 1985, László Cseh is the son of László Cseh Sr., who represented Hungary at the Olympics in swimming. He started swimming competitively at an early age, coached by György Turi and Zoltán Nemes. He held a scholarship with the Olympic Solidarity programme. His international breakthrough came at 17 with a silver medal in the 400m IM at the 2003 World Championships. At the 2004 Olympics, despite breaking his ankle before the games, he won bronze in the 400m IM. His career was defined by competing in the shadow of Michael Phelps, who prevented him from winning Olympic gold.

Where the conditions came from
Three sources, read side by side
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank László Cseh against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
What they brought
+1Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
World championship silver at 17, Olympic bronze at 18. Started swimming at 4.5. Self-described as 'not extremely talented' early, with much better swimmers in his age group. Strong determination and family support drove development.
Where it was dropped
What they were handed
+2Tailwind
-10+1+2+3
What money, family standing, network, or permission was already in place before the work began?
Father László Cseh Sr. was an Olympic swimmer who represented Hungary. Strong family domain inheritance in swimming. Father's Olympic background provided direct mentorship and genetic predisposition.
The shape of the track
What surrounded them
+2Tailwind
-10+1+2+3
What place, timing, institution, or peer group made the next step available?
Hungarian swimming system with coaches György Turi and Zoltán Nemes. Trained at Budapesti Spartacus SC. Olympic Solidarity scholarship provided support. Father's elite swimming background and Hungarian swimming tradition.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.

Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not László Cseh's worth or future potential.
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.

Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of László Cseh's outcome attributable to any origin.
Luck is not a leftover score.
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.
Within Athletes, László Cseh's starting-advantage total is at the 94th percentile. Separately, their built or converted leverage total is at the 97th percentile. Other T3 profiles average 5.3 / 24 starting advantage and 11.0 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
