8/8/8/P1p1k3/7R/1K6/6rP/8 b - - 0 53


{Mate in 32:} 53... Rg7 54. a6 Ra7 55. Ra4 Kd6 56. h4 Kc7 57. h5 Kb8 58. h6
Rh7 59. Rh4 Ka7 60. Kc4 Kb6 61. Rh3 Kc6 62. a7 Kb7 63. Kxc5 Rc7+ {Lomonosov
tables} *

EDIT: Magnus wins!   45. Bh7 Rc1+?

Perhaps this was the losing move?  Maybe 45... Ra1 46. Bg8+ Kc6 47. Bxb3 Rxa3 picking up the white a pawn for a draw was possible.

I think 51...Ke6 was losing and I believe 51...Re2! is drawing?

You might be correct, eg: 51... Re2 52. Kc4 (or a4) Rxe5 53. a4 {Draw:}{Lomonosov tables})

I guess the question is, can white do anything with 52.Rh5 protecting his e pawn?

52.Rh5 Ke6 seems to be a draw.

With the a and c pawns removed this is a draw because the black K is perfectly placed and both white's pieces are poorly placed.  Black keeps checking the white k until the a and c pawns drop or white's k is driven back to the a-file.   E.g. 53.a4 Re3+ 54.Kc4 Re4+ 55.Kb5 Rb4+ 56.Ka5 Rb1 57.Ka6 c4 = as now the c-pawn is strong e.g. 58.Rh4 Kd5!=

So 51..Re2 does indeed seem to draw.   Good spot by Cumnor CC
