1.e4 e6 2.d4 d5 3.exd5 exd5 4.Nf3 Nf6 5.Bd3 Bd6 6.O-O O-O 7.Bg5 Be6 8.Nbd2 Nbd7 9.c4 c6

White: Duras; Black: Nenakorov

It was better to isolate the d-pawn by 9...dxc4 and after 10.Nxc4 Be7 11.Ne3 Nd5 12.Bxe7 Qxe7 13.Re1 Qf6 Black can develop his Rooks undisturbed.


The beginning of an attack which hampers Black's Queenside pawns considerably. The point d6 has become strong for White, and if he succeed in getting a Knight round to post it there, the game would be decided in White's favour.

10...Be7 11.b4 Nh5 12.Be3 g6 13.Re1 Re8 14.b5 Bf6 15.Qa4 Qc7 16.Nb3 Nf8 17.bxc6 bxc6 18.Na5 Bd7 19.Rab1 Rab8 20.Ba6 Ne6 21.Nb7 Rf8 22.Rb3 Nhg7 23.Bh6 Bc8 24.Reb1 Qd7 25.Rb4 Nc7 26.Bd3 Nb5 27.Nd6

Faulty would be 27.Bxb5 cxb5 28.Qxb5 Rxb7

27...a6 28.Qd1 Ra8 29.Nxc8 Rfxc8 30.Qd2 Ne6 31.Be3 Nd8 32.a4 Nc7 33.Rb6 Ra7 34.Qa5 Kg735.h3

This move was unnecessary; he might have played 35.Bf4 at once.

35...Nde6 36.Rb7 Rxb7 37.Rxb7 Qe8 38.Qb4

White: Duras; Black: Nenakorov


By 38.Ra7 the a-pawn could not be won because of38...Ra8 39.Rxc7 Qd8

38...Ra8 39.Qb6 h6 40.Bd2

 Of course not 40.Rxc7 again, on account of 40...Bd8


White threatened g2-g3, Kg1-g2 and, after due preparations, Ba5. To this pressure Black would, in the end, have succumbed. The text move is a mistake, which accelerates the ruin.

41.Rxc7 Bd8 42.Bxg6 Kxg6 43.Qb1 Kg7 44.Rb7 Bf6 45.Qf5 Ng5

 The e-pawn could, of course, not be captured on account of 45...Nxd4 46.Nxd4 Bxd4 47.Qg4 and meanwhile 46.Bxh6+ is threatened. The position is defenceless.
