A game where a leading figure of hypermodernism, Richard Reti, introduces his revolutionary opening idea. This opening, later named after Reti, was called the 'Opening of the Future' by Savielly Tartakower, as it challenges the classical principles of opening play and sets the stage for a new era of chess strategy.

Reti vs Rubinstein, Karlsbad 1923
