The Open Ruy, a la Karpov-Korchnoi, 1978 (8): An update
http://chessmind.powerblogs.com/posts/1197440751.shtml


   A month and a half ago [1]I noted the game Thesing-Marin, which
   repeated a line of the Open Ruy generally condemned on the basis of
   the 8th game of the 1978 world championship match between Anatoly
   Karpov and Viktor Korchnoi. Both games started 1.e4 e5 2.Nf3 Nc6 3.Bb5
   a6 4.Ba4 Nf6 5.O-O Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.Nbd2 Nc5 10.c3
   and now 10...g6. Korchnoi was crushed in 28 moves and his 10th move
   found few followers, but one of them was Korchnoi himself! Still later
   Marin used it against Thesing, though the large rating disparity
   should give us pause before declaring the line safe and sound.
   In the post linked above, I tried to discern the truth of the matter.
   My conclusion was that 10...g6 is very risky and probably advantageous
   for White, but it's at least playable. This update doesn't undermine
   that conclusion or the novelty devised in that post, but adds to the
   source material and Black's troubles. The source is the man himself,
   Viktor Korchnoi, in the updated Olms Edition of Chess is My Life.
   Click [2]here to see his analysis (it's all his except when preceded
   by "DM"), with which I'm largely in agreement. The news, then, isn't
   news at all: Black will continue to struggle in this variation against
   best play.
