📘 Black's problem is clearly a mislocated bishop on g6.
14...Ne8! 15.Nf5 Bg5!
Exchanging the bad bishop and preparing to increase control over dark squares by Ne8-c7-e6. By moving the knight from f6 black can activate Bg6 by f6 and Bf7 in future.

📘 29...h4? (Qg5 was better)

📘 43.Bg3? Rd7? 44.Bf2=
As you can see in the following comments from GM Elshan Moradiabadi, after 43.Bg3? Black had a winning opportunity:
Black could win with 😏
47...c5!! 48.bxc5 [48.Bf2 d4! 49.cxd4 cxb4 Black king blocks white's central mass while the b-pawns decide the game.]
48...d4 49.cxd4 [49.Be1 dxc3 50.Bxc3 Rd7 And now the black's rook invade white's position. The game is practically over for white. 51.Kf2 Rd3 52.Be1 Rd5 53.Bb4 Rd4–+]
49...Rd7 50.Bf2 [50.Kf2 Rxd4 51.Ke3 Rc4 And the b-pawn decides]

📘 GM Moradiabadi:
16.Nxe6!? [A very deep idea which Gabuzyan failed to assess to correctly.]
16...fxe6 17.Rxc6 Ng4 18.Qd4 Bf6 19.Qxg4 Bxb2 20.Rb1 Bxc6 21.Qxe6+ Kh8 22.Qxc6 Ba3 23.h4! [And black king is rather weak. White has a tangible advantage here. It is not possible for human to calculate from here but intuitively one should feel that white is better thanks to his center and black's weak king.

📘 After setting up a drawing position, GM Melkomian, the former Armenian Champion, made a blunder by playing:
86...Ra7?
(86...Rf7 87.Rd7 Rf8+ 89.Rd8 (89.Kc7 K×g5) 89...Rf7=)
87.Rd7! Ra8+ 88.Kb7 Rg8 89.Kc7 Ra8 90.Rg7+ Kf5 91.Kb7 Re8 92.h7 1-0
86...Ra7?
(86...Rf7 87.Rd7 Rf8+ 89.Rd8 (89.Kc7 K×g5) 89...Rf7=)
87.Rd7! Ra8+ 88.Kb7 Rg8 89.Kc7 Ra8 90.Rg7+ Kf5 91.Kb7 Re8 92.h7 1-0
📘 16...Nd8!
To maneuver the knight to a preferrable square and to free the c pawn to either move it to c5 and control d4 or to play c6 and consolidate d5.

📘 An intetesting combination from Jobava.
21...Nxf2!? 22.K×f2 Qh4+ (B×e5 23.d×e5 Qh4+ --->Q×c4 was also possible)
23.Qg3 Q×g3 24.h×g3 B×e5 25.d×e5 R×c4=

📘 7...Nfd7
This move became popular among super grandmasters after Kramnik played it in 2000 against Adams. The idea is to maneuver the knight to e6 via f8 to increase control over the critical square d4. By delaying the short castle black has kept both the option of long castle and the option of h6 after Be3 and Qd2.
