YouRang: Interesting ending. It appears that the critical move came when white played <69.e5+> [diagram]

Black answered with the intuitive <65...dxe5>. However, this allowed <70.Ke4!> and <71.Kd5!>, and thereby the white king has wedged between the black king and the black c-pawn. From there, white was able to take black's pawns and push the white king away to the g-file (with 77.Rf1). After that, promotion was unstoppable. Black needed to find the less intuitive looking 69...Kf5!, which prevents the white king from gaining entry at e4. Note that white can't take the pawn with 70.exd6 due to the 70...Re1+ skewer. Also, pushing the passed e-pawn doesn't work: 70.e6 Rxa5 71.e7 Ke6, and white makes no progress. |
