Huỳnh Hữu Anh Khoa
2×2 · top 1.0% of 186,767 all-time · competing since July 2023 · 2023KHOA03
Huỳnh Hữu Anh Khoa has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.20, set at Vietnam Championship 2025, puts him in the top 1.0% of the 186,767 people who have ever been ranked in the event, and 11th in Vietnam. Until November 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since July 2023, he has put 204 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 84% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 one-handed best has come down from 14.77 in July 2023 to 10.98, a 26% improvement. He has entered six competitions, more competitions than 86% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
