📘 59.R×f5?=
It gives black an opportunity to equalize the game with Re8 and then Re1.
The winning continuation was:
59.Ra3! with the idea of Rf3 —-> K×f5. White with Covering 3rd-rank prevents the black rook to transfer the 8th-rank, for example, 59.Ra3 Rh8 60.Ne2+ Kd5 61.Rc3 +- Please see the diagram below👇👇👇

📘 In this position, white can win the game with the following processes:
1-transferring the king to d2.
2-Ne2
3-Rf1
4-Moving the king to f2 to defend g2-pawn.
5-Now Rc1
6- Maneuvering Ng1-Nf3-Ne1 and c2-pawn will eventually fall.

📘 36.c4?
It turns out to be a blunder that costs a pawn.
36...Nd6 37.Rc7 d×c4 38.B×c4 Ra1+ 39.Kf2 Rc1 40.b6 N×c4 41.b7 Rb1 42.R×c4 R×b7 -/+

📘 70.Rh4?!
Allowing black to play f5.
70.g4! was simpler and more logical which white draw should be secure: 70.g4 Ra6 71.Kg3 Kf7 72.Rh6! Ke6 73.g5 =

📘 12.Nb3!
White has more space so he keeps his knight on the board. Ivanchuk retreats his knight to b3 instead of f3 because the typical square for Black's dark-squared bishop is h6; with the knight on f3, the f4-pawn would then require guarding by the queen (of course White is not going to weaken the long light diagonal with g2-g3 just to guard the f-pawn).َ Also In some lines, Black castles long and it won't hurt for White to station a piece on the queenside to facilitate matters there.

16...Nb8!
Wonderful defensive resilience from Ivanchuk. Now, c4-c5 runs into ...Ba6 and Black also has the possibility of regrouping with ...Ba6, ...Nb7, .. .d7-d6 and ...Nd7, killing White's ambitions on the queenside.
16...h5 17.c5! White has the upper hand.
16...f3 17.Bh3 Nb8 18.Nd2 Ba6 19.Bg4 and after Re1-e3, the pawn on f3 will fall.
