📘 20...Raf8?! 21.Be3+/- prevents Bc5, defends f2, and threatens to take e5.
Black should have changed the move order and started with 20...Bc5.

📘 5.Qa4 is one of the anti-grunfeld lines in this position. Main alternatives are 5.d4 to transpose to Grunfeld, and 5.e4 Nxc3 6.dxc3 which is another anti-grunfeld line and a favorite of Ulf Andersson who loves strategic endgames!
📘 Critical moments of a game are the moments, inwhich the difference between the first and second best choices are substantial. In this position white continued with:
27.Nf3? Rbd8+ 28.Ke1 Nd3!+ 29.c×d3 Q×c3+ with a double-edged position.
He should have played 27.f.g7!e.d4?? (Kg8 was also losing 28.Bf1!+- with the idea of Bc4+) 28.g8=Q+! A move that Alireza may have missed
28... R×g8 29.Rf1+ Kg7 30.h6+ and mate follows.

9...Qc7 has been played with the idea of transfering the queen to its typical square in Maroczy bind, a5.
The more common variation is 9...0-0 and now:
A)10.0-0 Rc8! 11.b3 d5! which is a creative idea from Ivanchuk and we had covered it in our strategy multiple choice at unitychess channel few weeks ago.
B) 10.Be3 Rc8 11.b3 a6 planning b5.

📘10.Qe2
By playing Qe2 white is trying to deviate from the common 10.b3.
10...Nc6 11.Be3 0-0
And white can hardly claim any advantage here.

📘13...a5
Black is starting a minority attack on the queenside while c6 pawn has covered the d5 outpost. These are the consequences of taking on c6 in the Maroczy bind!

📘62.b5? cxb5 63.cxb5 Nd7
By an interception black wins the a pawn and the game. White should have played 62.Rb7 to prevent his rook from being cut off by Nd7 and then he could push the b pawn.
