The move 2.Bg5 was named after the Brazilian player Octavio Trompowsky (1897–1984), who employed it in the 1930s and the 1940s. The move led only a shadowy existence right up to the 1980s, but then some free-thinking English grandmasters, above all Julian Hodgson, took it up and demonstrated the vitality of this system, which has since that point become firmly established.
