[%c_arrow c5g1;keyPressed;none;from;c5;opacity;0.8;to;g1;persistent;false] A useful move. The king leaves the diagonal of the dark-squared bishop, protects the pawn on h2, and prepares the traditional plan of advancing the f-pawn. Abdusattorov played this same position against Grandelius just over a week ago, so this probably didn't surprise Giri.
