Kibitzer's Corner
Oct-10-06  bonzo: 23. ...Kxf7 losses?
Oct-11-06  pawn to QB4: Yes. 24.Qf3+ Kg6 25. Qe4+ Kh6 (or Kf7 26.Qd5+ Kg6 27.Qh5#) 26. g5+ Kh5 27. Qxh7+ Kg4 28. h3+ Kf3 29.Re3 + Kf4 30. Qe4# is as long as I can make Black last. Hope there's no gaping hole - I didn't have a set handy. Shows how defence has improved I guess: in ancient times this is how the game ends and Karpov gets a reputation as a dashing attacker.
Oct-11-06  Aspirador: <pawn to QB4> 24.Qf3 Kg8! is a gaping hole.

After 23...Kxf7 there comes 24.Rxa5! Rxa5 25.Qb3+ Kg6 26.Re6+ and wins.

Dec-02-12  sfm: To play a move like 22.g4 you need to be either beginner or supergrandmaster.
Dec-02-12  sfm: Amazing finish! White will play h4 and h5 and black loses the queen for a rook! No defense, of course -,Kg4 Rf8+,Kh7 Rh8 does not help!
Dec-02-12  rilkefan: I calculated 23...Kxf7 24.Rxa5 Rxa5 25.Qb3+ but stockfish improves with 24...Qc6 25.Qb3+ Qc4, +1.5. 23...Kh8 was a pawn worse.

17...b5 was a bit overly creative - ...Be6 is only +0.3.

SF suggests 22.Bxd6 cxd6 23.g4 Qd7 24.Bd5 as more accurate than 22.g4 Qf4, fwiw.

Jan-15-19  ndg2: Black Queen is nailed down to g6 and cannot prevent h4, h5. Great zugwang game (for lack of a better word, I know it ian't really zugzwang)

  perfidious: This game was the first instalment of a three-part duel in the Petrov between these titans in 1982, with Karpov vs Portisch, 1982 being Portisch's only win from Karpov with Les Noirs.
Nov-06-20  fisayo123: 22. g4! 23. Bxf7!! was a nice petite combination by Karpov ripping through black's king side protection. In the final position, the simple pawn march of h4 , h5 is irresistable
