Kibitzer's Corner
Jul-26-07  tal lover: Tal outplayed Miles in the endgame, probably w/ the best play it should be a draw after the game became a rook endgame
Jun-12-08  dTal: i'm not so sure, tal played a very fine endgame and he transitioned with a clear advantage

  perfidious: One would have thought that, after Tal's 23rd move, even with an extra pawn in the double rook ending, his winning chances were small; but this game provides an object example of the idea that in such endings, in which both sides possess weaknesses, active play is of utmost importance.
Mar-12-21  carpovius: <perfidious > Not at all. One has thought that 23...Rac8 was the loosing move. Very sorry.
