Less sharp and possibly safer is} (5...exd6) 6.Nc3 g6 7.Be3 Bg7 8.Rc1 {Removing the rook from the long diagonal.} 0-0 9.b3 {White is playing the popular and strong Voronezh Variation, named for a strong tournament in Voronezh Russia.} 9...f5!? {Black is hard pressed to complete his development normally, e.g.} (9...Nc6 10.d5 Ne5 11.h3) {threatens to win the knight by f2-f4, and} (9...e5 10.dxe5 dxe5 11.Qxd8 Rxd8 12.c5!) {followed by Bc4 is known to be better for White.} 10. f4? {Alternatives to stop the advance of Black's f-pawn include} (10. g3) (10.Nh3) (10.Qd2) e5 11.dxe5 dxe5 12.Qxd8 Rxd8 13.c5 exf4! 14.Bxf4 Bxc3+! 15.

Better is} (22...Ng4+ 23.Kg3 Nf6) {threatening ...Nh5+ and planning ...Ne4} 23.Bxd3 Rxd3 24.a4 Bd5? 25.Rd4 Rxd4 26.Nxd4 a6 27.b5 axb5 28. axb5 Ra8 29.Re1 Ra4 30.Ne2 Rb4 31.Nc3 Rb2+ 32. Re2 Rxe2+ 33.
