King's Indian Defence: the Averbakh Variation

The Averbakh arises after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 O-O 6.Bg5 (ECO E73). The bishop comes to g5 before the g1 knight is developed, pinning Black and obstructing the main plan - the ...e5 break.

White's idea is to restrict Black's counterplay: while the pin hangs over the position, the standard ...e5 is awkward and Black has to look for other plans (...c5 heading for Benoni structures, or ...h6 and ...Ne8-c7). A flexible, restraining system.

The variation is named after Yuri Averbakh. A convenient weapon for White against anyone who wants to impose unfamiliar play on a King's Indian player from the start.
