16. Bf6 This sets up a powerful mating net, which White could have sealed by getting his queen on the c1-h6 diagonal. Observers at this point thought the game would be over very shortly.

50. Ke6 50. d5 is more dir ect since the king cannot easily improve its position reletive to the Black rook.

55. d6 b5 55... Ra3 also holds.
56. Ke6 Ra7 ?? This is the losing move. The rook cannot respond to Whites coming attack.
56... b4 holds with the idea of sacrificing the rook for the unstoppable passed pawns. 57. f7+ (57. Rc1 Rxd6+ 58. Kxd6 Kf7 59. Ke5 b3 60. Rc7+ Kg8 61. Rc8+ Kh7 62. Rc7+)
57... Kf8 58. Rg1 Rxd6+ 59. Kxd6 Kxf7 looks winning for Black with the unstoppable pawns, but White could still draw by combing repetition and mate threats. 60. Rf1+ Kg6 (60... Ke8 61. Ke6 b3 62. Rh1 Kf8 63. Kf6 Kg8 64. Rg1+)

57. Rh1 White rehabilitates his rook with dramatic effect. Now everything happens with check and the a2 pawn cannot help.
