🔸½-½

White has some nasty threats like Rd1, Nxe4 or Bb3. Mamedyarov does not allow his opponent to develop his plan.

21. Qe3!
A multi-purpose move:
1- Moving the queen away from the x-ray of the Black's rook on the d-file.
2- Controlling of the weak b6-square.
3- preparing the pawn push e4–e5.

Carlsen's strange blunder. He could have obtained very serious drawing chances with 56... Bb4 57. Rxf6+ Kg7 58. Rf7+ Kh6.

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
