White should have prevented the black bishop from activating:

16... Qc5!
With the idea of ...Qe5, exchanging the opponent's active queen.
17.Rhf1 Qe5 18.Ne2 Qxf4 19.Nxf4 h4!
Gaining more space on the kingside.

GM Pouria Darini:
We were both in time trouble, but the draw was a logical result. There were two moves to obtain a draw by perpetual check: 59.Qc8+ and 59.Qc6+. I chose 59.Qc6+ in order to tempt my opponent to play 59...Kf5??. Fortunately, while he was thinking about that, the time was over.
59. Qc6+ 1-0
A)59...Kf7 60.Qd7+ . With perpetual check
B) If 59...Kf5??, then 60.Qc8+ Qe6 61.e4!+ dxe4 62.Qf8+ Kg4 63.Qf4#

18.Nxd6!
A well-calculated sacrifice by Mosadeghpour.

The last move was 22 Nd2-e4 with the idea of swapping the strong enemy knight on c5.
22...Bf5!
The most tempting reply, and the best one as well! Black prepares to exchange his bishop for the white knight so that his own, powerful knight will remain on the board.
23.Rc4 b3 24.Qc1
By unpinning the knight White managed to avoid any tactical surprises; however, the opponent's reply will leave him with a clear strategical inferiority.
24...Bxe4! 25.Bxe4 f5 26.Bg2 Qa5
By now the virtues of the ...Bf5xe4 plan are easy to grasp. The firmly installed knight outshines the passive bishop, and the b2-pawn is a burden in the long run.

White has just played 27 Rd2-e2, with the probable intention of Rfe1 creating a mating threat.
27...g6!
A typical prophylactic measure. With ...Kg7 next, Black safeguards the king from any surprises along the back rank. Moreover, he takes the f5 and h5 squares from the white queen and knight.
28.Rfe8 Kg7
All of a sudden White has fallen short of active plans, whereas Black is waiting for the right moment to attack the b2-pawn.
29.Ng2 h5!
By setting up the positional threat of ...h5-h4, Black aims at provoking a weakness in the enemy camp.
30.h3 Rd6 31.Nf4! Rb6 32.Rb1 c3! 33.b4 a5 34.Re4 Rd8!-+
White managed to save the b-pawn, but now the second rank proves to be too vulnerable.
