Trompowsky!

The Trompowsky is a popular alternative to the more common lines after 1.d4 Nf6 beginning 2.c4 or 2.Nf3. By playing 2.Bg5, White sidesteps immense bodies of opening theory of various Indian Defences like the Queen's Indian and the King's Indian. The opening is named after the one-time Brazilian champion Octavio Trompowsky (1897–1984) who played it in the 1930s and 1940s. The Trompowsky has also been called The Zot.[1]
