📘After white's dubious move 5.Nc3 black replies with 5...f6. 5...f6 has been played by Aravindh in the previous year. Shirov, Kramnik, Moiseenko and Radjabov have played f6 against other white fifth moves. An idea of f6 is to not allow white to easily play e5 to weaken c5 after black plays d6.
It seems that on the 5th move white should avoid the comitting move Nc3, since this knight blocks the c pawn and deprives him of ideas such as c4 or c3, and d4.

📘 The young 2016 Iranian Champion played 35...c4 with a decisive advantage.
He could have concluded the game with a stunning last scene.

📘 In the game white tried the rare 15.Rac1. One of the most important positional ideas in this position is transfering the knight to the weakened b5 square.
The most common alternative, which was played by Movsesian and Kovacevic, is 15.Nc1 with the idea of regrouping the pieces by transfering the bishop to c2 and knight to c3 and playing a3, and b4 at the end.
Another interesting alternative is 15.Rae1 with the idea of f4, trying to free d4 for the knight. But after 15.Rae1 Nd7 16.f4 Nac5! black equalized in Ivanchuk- Dominguez 2009.

📘 35...g5! -+
This move can be called a wise choice, considering the weakness of the white's backrank.

📘 10.Ra4!?
Restricting black's knight and preparing to attack c6, the base of pawn chain, by playing b4-b5.
In the game black replied 10...Nexc5?! 11.dxc5 Nxc5 12.Ra3 without enough compensation for him.
10...f6!? was an interesting alternative, covering e5 and preparing for g5.

📘 15.Ng5!
Black has not played the necessary h6. White makes use of his oblivion and launches an attack on the kingside.
15...Re7 16.Nh5! Rd7? (After the almost forced move 16...Ne8 there was no forced win and black could repel his attack by playing h6)
17.Re3! with a decisive attack.
A simpler forced win would be 17.Nxf6+ Qxf6 18.Nxh7 Kxh7? 19.Qh5+ Kg8 20.Bg5 g6 21.Qg4+-

📘 5.Bd3
White players used to take on d7 for years; However, after Bartel in 2011, Caruana in 2012, and Carlsen in 2013 played this move its popularity increased and now it can be called the main line. The idea of this move is to continue with c3, Bc2 and d4, to reach a typical Lopez type of position.
