Editing King's Indian Defence (section)

=====Sidelines=====
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 GM [[Burkhard Malich]] in the 1960s and 1970s.<ref>365chess.com, results search for Zinnowitz Variation games</ref> It is currently unfashionable at master level; Black gets a good game with 6...h6, and if White retreats with 7. Bh4, then Black can play 7...g5 8.Bg3 Ch5!, which isn’t possible in the Averbakh variation, in which White plays 6.Be2. 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.

Another, more significant and quite popular sideline occurs for Black on move 6, with 6...Bg4, in place of the mainline 6...e5. One idea for Black here is to relieve their somewhat cramped position by exchanging their light-squared bishop, which is often relegated to a passive role in the King's Indian. White's most popular response is 7.Be3, similar to the Gligorić System (see above); White seems to retain a small edge in every variation. Top players who have used this line for Black include two former World Champions: GMs [[Mikhail Tal]] and [[Boris Spassky]].<ref>"Batsford Chess Openings, 2nd Edition", by [[Garry Kasparov]] and [[Raymond Keene]], Batsford publishers, London 1989, section on King's Indian Defence</ref> 

After 6...c5 7.0-0 cxd4 8.Nxd4 Nc6, the game transposes into the [[Sicilian Defence, Accelerated Dragon|Accelerated Dragon]] variation of the [[Sicilian Defence]].
