At move 29, it appears to me that the main imbalance in the position is white's passed d pawn. I'm kind of surprised Karjakin let it go so easily.

Hi Fast Eddie,


The d-pawn is never going to get past d5 (white square) if Karjakin wants to
hold it then it has to be on d4 and the Bishop on e5.

The Black Bishop can sit on d5 and play a part in attacking in the Queenside where
Carlsen is stronger. The d4 pawn will hinder the Bishop defence of the Queenside.

The White Queen will be out numbered and Black can create threats. They might not
be winning threats with best play but why do that to yourself, put yourself in a position
where you need to play the best moves when you have no chance of winning.

The d-pawn is never going to do anything. Let it go and kill the Queenside.

Thanks.

I guess I was envisioning the queens and bishops magically vanishing in that position. Them Black's king would have to stop the d-pawn, freeing white's king to mop up pawns elsewhere. But I'll stipulate the players here can probably see a tad deeper than my typically 1700-1800 self can.
