David Bronstein introduced this variation in game 14 of his 1951 World Championship match against Botvinnik.
8...Nd7
9.Re1
over-protecting the key e5-pawn. It is now hard for black to counter with f6 or f5, because, after exf6, the black e-pawn would become a target.
9...b5
So black counter-attacks on the queenside.

Up to here, following the Bronstein-Botvinnik game

N Bronstein instead tried 13.c3. The usual idea is to leave the queenside pawns alone and to pursue the kinside attack.

15...Ba6
16.Bh3
Putting pressure upon the e6-pawn, again to discourage black from advancing the f-pawn
16...d4
opening d5 for a knight, and giving the Ne3 a tough decision between f1 and g4
17.Nf1
With the idea of Nd2-e4
17...Nb6
Heading to d5 and e3 or c3

If now Bxg5, white can play hxg5 and use the open h-file.
