1.c4 f5 2.d4 g6 3.Nc3 Nf6 4.Nf3 Bg7 5.g3 0-0 6.Bg2 d6 7.0-0 Qe8 8.Re1 Nc6 9.d5 Na5 10.Nb5 Qd8 11.Qc2 c6 12.Nbd4 cxd5 13.Ng5 Qb6 14.Nde6 Bxe6 15.Nxe6 Rfc8 16.Be3 Qa6 17.b3 dxc4 18.b4 Nc6 DIAGRAM Shedd-Valvo W19 19.Qc3 Bh8 20.Rac1 d5 21.Qd2 Qb5 22.Bc5 Ne4 23.Bxe4 dxe4 24.a4 Qxa4 25.Qd5 Nxb4 26.Bxb4 Qc6 [26...Qxb4? 27.Ng5+ soon mates. 27...Kg7 28.Qf7+ Kh6 29.Qxh7+ Kxg5 30.Qh4#] 27.Nf4+ [27.Nc7+ as pointed out by the elder Ponomarev after the game, appears to give White chances to hold the game. However, it's still a difficult posittion. 27...Qxd5 28.Nxd5 Kf7 29.Nxe7] 27...e6! this move shows that 27.Nf4 and 27.Nc7 are not equivalent! 28.Qxe6+ Qxe6 29.Nxe6 a5 30.Bc3 b5 and here it appears the 3 pawns are just stronger than the knight. 31.Bxh8 Kxh8 32.Nd4 [32.Red1 seems to be a better try at defense, but probably ultimately futile.] 32...b4 33.Rb1 Kg7 34.Rec1 Kf6 35.e3 Ke5 36.Kf1 Kd5 37.Ke2 c3 38.Rb3 Kc4 39.Rcb1 Rab8 40.Nc2 Rd8 41.Ke1 Rd2 42.Nd4 Rxd4 43.exd4 c2 0-1
