Zenchess: AJ, thanks for the annotations; Korchnoi is one of my favorite players. Here is the link:
Here are my impressions of this game:
--9. d4?! is questionable; see AJ's notes of this game on his site. I would add that 9. b3! was better because White can capture if Black goes ...b5. White is better here.
--14. Rc1?! was another sloppy move; what about 14. e3!? This protects the Knight so the Queen can move off d1. White can follow with 15. Ne4 and Qh5 targeting h7 after the Nf6 is exchanged or driven away. If Black then plays ...f6 to stop Ng5, White can play Bh3 to tie Black's pieces down to the newly-weakened e6 pawn.
--I think that playing e3 on move 14 is better than on move 15; AJ's 15. e3 line is not as good (but still equal) because the Q still has to guard the Rc1. The idea behind e3 is to free the White queen to roam around and provoke weaknesses.
--I agree with AJ's criticism of 15. Nf3; White trades off a perfectly active N for an unguarded N that is blocking Black's e6 pawn from advancing.
--On move 17, Chess Tiger 15 disagrees with most other comps and recommends 17. a3 Bc6 which it considers Black a quarter of a pawn better. But after I feed it 17. Ne4, its evals equalize. It agrees with Korchnoi's criticisms of 17. Qb3 and gives Black almost a half a pawn advantage.
Is this Korchnoi's immortal game or is there one better than this?
