[Rohde]
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4 Qb6 A move designed to avoid the Sozin / Velimirovic after 6 ... e6 7 Be3. 7.Ndb5 Alternatives are 7 Nb3 and 7 Nde2. 7...a6 8.Be3 Qa5 9.Nd4 Ne5 White would get a strong attack after 9 ... Nxe4 10 Qf3. But 9 .. Ne5 seems to result in a loss of time. Perhaps 9 ... e6 is most solid. 10.Nb3 Qc7 11.Be2 e6 12.f4 Nc6 The reason 9 ... Ne5 was problematic is that now 12 ... Nc4 13 Bxc4 Qxc4 14 Qf3 leaves White with strong possibilities of e4-e5 very soon. 13.g4 b5 14.g5 Nd7 On 14 ... b4, 15 Nb5!? axb5 16 gxf6 may be White's best way to prosecute the attack. 15.Bf3 Bb7 16.Qe2 b4 17.Na4 a5 18.c4 Be7 19.0-0 0-0 White's space advantage is the basis for a real edge; yet Black has no concrete weaknesses. 20.Rac1 Rfd8 21.Qf2 Nc5 An interesting series of exchanges, opening the position. 22.Naxc5 dxc5 23.Nxc5 Bxc5 24.Bxc5 Qxf4 25.Be3 Qe5 Better was 25 ... Qc7. Now Black starts to get into problems. 26.Bg2 Rd7 27.Rcd1 Qc7 28.Bb6 Qc8 29.Qf4 e5 30.Qf5 Nd4 31.Qxe5 Ne6 32.b3 a4 33.Be3 axb3 34.axb3 Qd8 35.Rd5 Qe7 36.c5 Nc7 37.Qxe7 Rxe7 38.Rd4 Rae8 39.Bf4 Ne6 40.Rxb4 Nxf4 41.Rxf4 Rc8 42.Rb5 Bc6 43.Rb6 Re5 44.Rf5 Ree8 45.Rf2 Re5 46.Bh3 Rc7 47.Rb8+ Be8 48.c6 1-0
