Carlsen's strange blunder. He could have obtained very serious drawing chances with 56... Bb4 57. Rxf6+ Kg7 58. Rf7+ Kh6.
57. Kh3??
Mamedyarov gives him another chance.

10. a5 {A highly committal move. White wins space on the queenside and the tempi spent on advancing the a-pawn will be retrieved thanks to the relatively unsafe situation of the bishop. At the same time, Black is deprived of the freeing move ...Na5 forever. On the other hand, Black no longer has worries on the queenside and he can even hope that at some point the a5-pawn will become weak.} Ba7 ({Accepting the sacrifice with the king uncastled is dangerous.} 10...

It's not surprising that with White's pieces offside, Black gained some counterplay, but White was able to regroup in order to gain the full point:
22.Ra3! Ndf6 23.Rea1 Qd7 24.R1a2 Rfc8 25.Qc1 Bf8 26.Qa1 Qe8 27.Nf1! Be7 28.N1d2

“Whenever Black succeeds in assuming the initiative and maintaining it to a successful conclusion, the sporting spirit of the chess lover feels gratified, because it shows that the resources of the game are far from being exhausted.”
