[Stoyko, Steve]



1.e4 e6 2.d4 d5 3.Nd2 c5 4.Ngf3 Nc6 5.exd5 exd5
[ This line with the isolated d-pawn gives Black free development but 5...Qxd5 is currently preferred.]

6.Bb5 Bd6 7.dxc5 Bxc5 8.0-0 Nge7 9.Nb3 Bd6
In this position... - White blocks the d-pawn withNbd4, hoping the Blackwill trade Ns there, and will often often retreat his Bb5 back to e2 (not d3), so that, if his opponent exchanges on d4 again, he can retake with the Q, not the P [after c3] (ever!). - Black tries to break the d4-f3 N connection with ...Bg4 and get active play with either or ...Re8.

10.Bg5 0-0 11.Bh4 Bg4 12.Be2 Qb6 13.Bxe7
[ The natural 13.Bg3 was met by 13...Bxg3 14.hxg3 Nf5! 15.Qxd5 Nxg3!= in Aepfler - Dittmar : Weilburg 1996]

13...Nxe7 14.Qd4 Qxd4 15.Nfxd4 Bd7 16.Rad1 Rfd8 17.Rfe1 Kf8 18.c3 a5 19.a3 a4 20.Na1 Nc8 21.Nac2 Nb6 22.Ne3 Bf4 23.Ndc2 Be6 24.Rd4 Bxe3 25.Nxe3 Nc4 26.Red1 Rdc8 27.Nxd5 Nxb2 28.Rb1 Bxd5 29.Rxd5 Nc4 30.Rxb7 Na5 31.Rbb5 Nc4 32.Rd7 g6 33.f4 Ra6 34.Rb4 Rac6 35.Bd3 Kg7 36.Rd4 Nxa3 37.c4 Ra6 38.Kf2 Ra5 39.Ke3 Rc7 40.Kd2 h5 41.Re4 Rd7 42.Re1 Rc5 43.Rc1 Rd4 44.Ke3
Notice how few chances Black had in this game. It seems that [after ...exd5] it is an uphill struggle to draw. 1-0
