Sozin Attack

He advocated the Sozin Attack (White's 6.Bc4 ) against the Sicilian Defence, Najdorf Variation around 1930, which became popular from the 1950s, and was frequently employed by Bobby Fischer, who refined and advanced its theory whereby it became known as the Fischer–Sozin Attack.

Sozin Variation

In 1925, Sozin introduced the Sozin Variation (Black's 11...Nxe5) against the Semi-Slav Defense, Meran Variation (ECO D49) in the Queen's Gambit Declined, which since has become standard play.
