28...Ng6?
A carelessness. Navara has appeared less than expected so far in this tournament.
28...Kf8!
A) 29.e6 Rcd8 =
B) 29.Rb6 Rb8=
C) 29.f4 g6 =
29.e6!
Mamedyarov fully Exploits the opportunity.

31...Rh8??
Ivanchuk, who was under plenty of pressure in the opening and middlegame, is clearly losing his focus.
The better move is 31...Ngf4, intending ...Rh8. White still being a pawn up but he should fight for a win.
32.e6+! 1-0

31. Nxg7!
Although Parham was in time trouble, cleverly noticed that he had to complicate the game.
31...Kxg7 32.f5 Bh7 33.Qxd3 Kh8 34. Qg3 Rg8 35. Qf3 Ne7 36.Bd7?!
36. g4 = is more solid.
36... Rc5 37. f6 Ng6 38. e6 Ne5 39. Qd1?!
39. Qf4 is the precise continuation for White. 30...Qxf4+ 40. Rxf4 Rc2 41.Rg1 Nxd7 42. exd7 Rd2 43. b4 axb4 44. Rxb4 Rxd7 45.g4.

25.g4!
A strong prophylactic move that prevents Black from playing ...Nf5 and freeing himself. After this move, White can easily play Qh6 and then launch Rc3-h3 maneuver.
