(To blunt the bishop)

Position after 17.f4
17...c4! 18.dxc4 Qb6 19.Rh3 Rb8
(Black has activated his position at the cost of a pawn and a defensive move like Kb1 makes sense now but Motylev decides to sacrifice a piece and regain the initiative)
20.g4!? dxc4 21.Nxc4 fxg4 22.Qxg4 Bxc4 23.f5 Bd5 24.f6?
