22... Bxg2!
With exchanging the light-squared bishops, Mosadeghpour weakens the White's king position and prepares to undermine his opponent center.

White has two good options:
A) 13.Qa5!?
An interesting move that was introduced by Anand against Topalov in 2008. 13...Bh6 14.B×h6 R×h6 15.Kb1 Rc8 16.Qb4 Kf8 17.c4 Kg7 18.g3 1-0
B) 13.Kb1
Another good move that was played by Leko against Giri in 2012.
13...Nbxd5 14.Bg5 Be7 15.Na5
Grischuk employed this novelty against Topalov in 2015.

With a strong attack on the kingside.

54...Ra7?
Black should have prevented White from playing c4, because in that case, he would activate all his pieces.
54...Qc7!
A) 55. c4 Ra7 56.Qb5 Rb7
A1) 57.Qa6 Ra7 = with move repetition.

37...Bd7??
A blunder. Black leaves his own pieces on the same file that will allow his opponent to exploit that by tactical means.
37...Kf8! 38.Rh2 c4 39.Rh8+ Ke7 40.Rg8 Kf7 41.Ra8 Bd7+/-
White is still better but if Black plays precisely, his task is not easy.
