wim van os: Dear notyetagm, i think you are complete wrong. From the 12th move (f5!) to 25th move she overplayed Rublevsky. At that moment she is 2 pawn ahead and all pieces far more active. Just after 28...Bd5? 29.Nxh6! things go very wrong.
 
   Oct-02-07 A Sellman vs E Delmar, 1880 (replies)
 
wim van os: It is so easy to spoil a endgame! Black throw it all away with 43... Kd5?? The difference with 43...Kd4!! seems so small but it is the decisive tempo! 43... Kd4!! 44.Kb6 c5 45.Kxa5 Kc3 46.Kb5 Kxb3 is a draw as black’s king is in time to take the f-pawn if white’s ...

wim van os: I don´t agree with Chessical 40.f3? is even bad as black gets after 40...b5 very dangerous pawns at the queen side: 41.c3 a5 42.a3 a4 43.Kg4 Kd5 Black was running out of moves and had to sacrifice a pawn. But he will queen fast on the queen side after: 44.Kxf4 Kc4 ...

wim van os: with 29.c4?! white seems to win even easier as it wins time but after the topical break manoeuvre 29...Ke5 30.Kg4 Kd4 31.b3 a6! 32.Kxh3 b5! the white position nearly collapses. It should be a draw after 33.Kg2 bxc4 34.bxc4 Kxc4 35.h4 Kd3 36.g4 c4 37.h5
 
   Oct-02-07 Torre vs Feagin, 1926
 
wim van os: I guess 39. a4 is all right. The decisive mistake is 40.Kh5 because the way to the pawn is too long. The odd looking 40.Kh7!! is the fastest way to the black pawns! Now 40...Kf7! 41.Kh8 Kf6 is a draw If black tries to win by letting the kings run to the pawns it is white who ...
