The position after 58.Kc7 is won for white and white did not allow a draw position afterwards. Could Black have saved the rook ending somewhere ?

1

Yes, Black had a chance to save the game on moves 45, 46, and 48. Her entire plan from 45 to 49 is wrong. She needed to bring her king and leave the rook uncommitted (in various positions) for as long as possible. See the analysis below (thanks to Stockfish 6 x64 in Deep Fritz GUI).

Probably GM Sebag calculated that she could win the outside a-pawn, but did not consider that this plan would lead to a lost rook and pawn endgame. Or, she got to that point, saw that 49...Rxa3+ was losing either way, so she opted to go for tactical chances.

  • The pgn viewer still needs an improvement to handle game fragments starting with a move number different from 1, see meta.chess.stackexchange.com/questions/181/… – Dag Oskar Madsen Apr 4 '15 at 14:26
  • Thank you @DagOskarMadsen. I have prepended the moves 1-37 to the game so that it shows properly in the PGN viewer. – Mavaddat Javid Apr 4 '15 at 23:05
  • There are too many mistakes in your PGN, the main line (game continuation) doesn't make sense. Maybe you should repost the PGN. – Dag Oskar Madsen Apr 4 '15 at 23:30
  • I realised that just now too. I am creating a new PGN now. – Mavaddat Javid Apr 4 '15 at 23:30
  • @DagOskarMadsen, The PGN is correct. The PGN viewer does not recognize nested variations correctly. Please see the full analysis on Chessbase: viewchess.com/cbreader/2015/4/4/Game362695015.html – Mavaddat Javid Apr 4 '15 at 23:50
