When Your Pawns are All in a Row, Your Ducks may also Be

It was not by grand design that three of my pawns ended in a row on the G file. Surely, a series of exchanges put them there, but odd as they come. In strict chess theory, each one represents a weakness. I found that with Victor Korchnoi, his games contain much scattered pawns across the board. His tactical style is a factor. Capablanca, inversely, prefers strategic play. His pieces tend to be linked together, as if holding hands. But, in the general sense, at their master level games, a piece or pawn are only weaknesses if they are attacked. 

White's move, after Black's 28...Rd1 (diagram), White resigned being a rook down and no possibility of active counterplay. This is where the odd pawn formation provided protection for Black than chances of counterattack from White.

A pawn-grabbing line like 29. Qg5 would immediately fail with 29...Qe2+. Moving the White rook to any square on the second rank, queenside, will result in 29...Qf1. And if 29.Rf2, that leads to a further exchange of material and a strong intrusion into White territory by Black--such as 29.Rf2 Rf2+  30.Qf2 Qd3 threating 31... Rd2.
