Gunderam Defense
The Gunderam Defense, also known as the Brazilian Defense, is a rarely played chess opening starting with the moves: It is named after chess player and theoretician Gerhart Gunderam. History. Gunderam played it for the first time in a correspondence match against August Babel in 1958 and published an analysis of it in his book "Neue Eröffnungswege", in 1961. He named this defense ""Damenverteidigung"" ("Queen Defence"), whose main line would be 1. e4 e5 2.Nf3 Qe7 3.Nc3 c6 4.Bc4 f5. He also analyzed a sharp line characterized by the moves: 1.e4 e5 2.Nf3 Qe7 3.Bc4 f5 4.exf5 d5  5.Bxd5 Nf6 6.Bb3 Bxf5. Overview. Although 2...Qe7 does answer the threat against Black's e-pawn, it interferes with the development of Black's dark-square bishop. One of the ideas behind this awkward queen move is to unbalance the game by castling queenside while White will presumably castle kingside. Brazilian Defense. The 2...Qe7 response appeared in Brazil in 1954, created by International Master Hélder Câmara. Whereas Gunderam's suggestion was the f7-f5 break, as a delayed Latvian Gambit, Câmara's intent was to allow the use of the King's Indian setup against King's Pawn  opening, proceeding with ...g6, ...Bg7 and ...Nf6 after 2...Qe7. It became popular among Brazilian players then, so much so they begun calling it "the Brazilian defense", being employed often in the top national competition the following years. Later on, Hélder Câmara requested that it be called "Camara Defense" instead. Notable Games. August Babel vs Gerhart Gunderam, Germany (corr), 1958
