was hoping to achieve more using his active
rook.

Transferring the king to the queenside came
into consideration: 23@e3 !? i.b6 24 Wd3 ~d6+

This at first glance logical move allows Black
to relieve the pressure by means of a pawn sacrifice.
Otherwise:
a) 24 e4?! l;!d6 gives Black counterplay.
b) 24 a3 ! t is correct, so as to have the move
b4 available in many variations. For example,

This error in time-trouble lets slip White's
advantage. With both sides short of time, Dautov
failed to find the best way: 36 l;!d7 ! i.c7

despite the reduced material Black comes under
