  ...Kh5 is a better way to get the king out of danger, as compared to ...h5, since now if the white king moves, there's no discovered check. Some lines:
  
  a) 34...Qxb2+ is what Black wants to play, but this blunders to 35.Kf1+ Kh5 36.Rh3#.
  
  b) 34...h5, as played in the game, continued 35.b3 Qe2+ 36.Rf2 Qe4+, at which point Karpov should have played 37.Kh3+ Kh7 38.Rf7+ Kh8 39.Rf6, and the geometry of the position gives White a winning advantage. If the king were on f1, Black would be able to get a draw (with correct play) by checking from the side.
  
  c) 34...Kh5 is best. Now:
  
  * c1) 35.Rh3+ Kg4 36.Rxh7 (36.Rg3+ Kh4 37.b3 Qe2+ will be a perpetual) Qxb2+ 37.Kh1+ Kf5 is a tablebase draw. Although Stockfish gives this as +0.63, which indicates this may not be so trivial for a human to draw.
  * c2) 35.Kh1 threatens Rh3#, but 35...Qd5 36.Rgf1 Qxa2 snags a queenside pawn anyway, and once again a tablebase draw.
  * c3) 35.b3 is met with 35...Qe2+ 36.Rf2 (36.Kg3 Qe5+ gets White nowhere) 36...Qe4+. This position was reached in the game (and in this answer earlier), but where the black king and pawn were on g6 and h5 respectively. But now, since the king is no longer on the g-file, 37.Kh3 does not come with check. After something trivial like 37...Qh4+ 38.Kg2 Qe4+, the position repeats.
