A minor but still significant sideline occurs for White on move 6, with 6.Bg5, the Zinnowitz Variation, instead of 6.Be2 e5. The line was played several times by German Grandmaster Burkhard Malich in the 1960s and 1970s. It is currently unfashionable at master level; Black gets a good game with either 6...h6 or 6...Nbd7. This line is distinct from the much more popular Averbakh Variation, described below, since in the Zinnowitz, White has played 5.Nf3 instead of 5.Be2, as in the Averbakh, and then follows with 6.Bg5.
