Richard Réti (1889 - 1929) was a Czechoslovakian chess player, although he was born in what was then Hungary.
One of the top players in the world during the 1910s and 1920s, he was one of the proponents of hypermodernism, along with Aron Nimzowitsch and others.
The Réti Opening (1. Nf3 d5 2. c4), with which he famously defeated the world champion Jose Raul Capablanca in New York in 1924 — Capablanca's first defeat for many years and the first since becoming World Champion — is named after him. He was also a notable composer of endgame studies.
He died in 1929 of scarlet fever.
