27... Kh6 28. g4 fxg4 29. Re6+ |
? This allows the Black King down to h5; better was to first restrain him with 29.hxg4. | ||||
| | |||||
|
29... Kg7 |
? 29...Kh5 was better, gaining the h-pawn in exchange for the g-pawn and retaining some (albeit very slight) chance for counterpressure down the h-file. | ||||

30. hxg4 h6 31. Ree8 Kf6 32. Rd5 Kg7 33. Rdd8 Rf4 34. Rd7+ Rf7 |
Probably 34...Kf6 would have been better, retaining more activity for the endgame (after 35.Rf8+ Kg6 36.Rxf4 gxf4 37.Rxc7 Kg5). | ||||

Black's King is far more active than White's, but there's no way to force a pawn through with that Rook drifting around on the 7th rank and the WK guarding the coronation squares. | ||||

39. Re7 Kxg4 40. Rxe4+ Kf5 41. Re8 h5 42. Rf8+ Kg4 |
42...Ke4 was better; the text allows White to trap the BK on h4 with 43.f3+! and quickly clean up his remaining pawns without any worry about advancing Black pawns. | ||||

|
43. Kh2 h4 44. f3+ Kh5 45. Kh3 Kg6 46. Kg4 |
Black has lost all his activity, and with it any hope for counterplay. | ||||

46... a5 47. Rb8 a4 48. Rxb6+ Kf7 49. Rh6 Kg7 50. Kxg5 h3 51. Rxh3 Kg8 |
? This is sort of a silly thing to do. Black is presumably hoping that White will advance pawns willy-nilly and end up with a stalemate, but this move actually sets up a very simple mate in three for White (52.Kf6! a3 53.b3 Kg8 54.Rh8#). The BK needed to remain on the seventh rank as long as possible with 51...Kf7. | ||||

52. Kg6 |
? White either does not see the mate or does not care to look for it. I expect (based on White's choices in the remainder of the game) that it is the latter, but it's always best to take the simple, guaranteed mate if it's there. From here on out, White doesn't do anything terrible to let Black out of the mating net, but he also ignores the simple KR endgame and instead goes for the promotion. | ||||

52... a3 53. bxa3 Kf8 54. Rh7 Kg8 55. c4 |
Should have been mate in two: 55.Rf7 Kh8 56.Rf8# | ||||
| | |||||

55... Kf8 56. c5 Ke8 57. c6 Kd8 58. Kf6 Kc8 59. Ke6 Kd8 60. Kd6 Ke8 61. c7 Kf8 62. c8=Q# |
There you have it. Perhaps a slower mate than necessary, but certainly smoothly-executed by White. Black's failure to understand the urgency of keeping pieces near the central pawn structure when down in material led predictably to those pawns becoming vulnerable, and falling in due course. Hope you enjoyed! | ||||
