[2] Grandmaster Jonathan Rowson wrote in his book Understanding the Grünfeld that Nadanian "should be congratulated for seeing what everyone has seen, and thinking what nobody had thought".

[4]White's fifth move is overprotecting the key c5-square in the Grünfeld Defence, thus aspires to prevent an attack on the pawn centre by c7–c5.

[5] The main line continues 5...Bg7 6.e4 Nb6 (Avrukh's 6...Nb4 is also interesting) 7.Be3 0-0 8.Nf3 Bg4 (instead 8...Nxa4 9.Qxa4 c5 10.Rd1 Qb6 11.Rd2 was good for White in Korchnoi–Sutovsky, Dresden 1998) 9.Be2 Nc6 10.d5 Ne5 11.Nxe5 Bxe2 12.Qxe2 Nxa4 with approximately equal chances.

Another possible line is 5...e5 6.dxe5 Nc6 (suggested by Igor Zaitsev and first played by Mikhalchishin), which is according to Lubomir Kavalek "perhaps the only way to punish the white knight's venture to the edge of the board".

Various famous players such as Viktor Korchnoi, Maxime Vachier-Lagrave, Bu Xiangzhi, Alexander Riazantsev, Igor Lysyj, Walter Browne, Smbat Lputian, Timur Gareyev, Jonathan Rowson, Andrei Kharlov, Bogdan Lalić have employed it at some time or another, though few have made it their main line against the Grünfeld Defence.
