26. Qd7?
The Chinese Grandmaster failed to find the correct move and blundered.

31. Qc2??
White attempts to exchange the queens in order to reduce his opponent's attack. However, it's, in fact, the decisive mistake!
He could have played 31. Nd4! and now:
A) 31...Qg6 32. g3=
B) 31...Qf4 32.g3 =

11. Bxb5!
Alireza has chosen an interesting line.
11...axb5?
11...Rc8! would be correct:

Attempts to continue to hit h7 will be fruitless whereas e6 is now clearly a weak point:
21.Ba2! a6 22.Nc3 Rce8 23.Nf3 Bd8 24.Ng5 Qc8 25.Rxe6! Rxe6 26.Nxd5 h6 27.Nxf6+ Kh8 28.Qxf5+ Re1+ 29.Rxe1 Qxf5 30.Nf7+
and Black resigned.

White's straightforward central breakthrough idea was potentially very dangerous.
10...h5!
was an 'intuitive, genuinely Sicilian, strong' move, which deterred White from a swift f2-f4 and e4-e5 plan. Note 10...g5 11.h4! would have been awkward.
11.h3 Qc7 12.f4 Nc4 13.Bxc4 Qxc4 14.Qf3 h4 15.Bh2 Bd7 16.0-0-0 Rc8 17.Rhe1 b5 18.Qf2 Qc7 19.e5 b4 20.Rd3 dxe5 21.fxe5 bxc3 22.Rxc3 Qxc3
The text is certainly visual, although apparently 22...Qb8! would have been stronger.
