Dus-Chotimirsky - Cohn

St Petersburg 1909

Queen's Gambit Declined

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Nbd7 5.Bf4 dxc4 6.e3

To 6.e4 the well known reply is 6...Bb4

6...Nd5 7.Bxc4 Nxf4 8.exf4 Bd6 9.g3 c6 10.O-O O-O 11.Re1 Nf6 12.Ne5 Qb6

White: Dus-Chotimirsky; Black: Cohn

More consistent would be 12...Nd5 and then, if 13.f5  (and if 13.Ne4 Bc7 14.Qh5 h6 it is not at all clear how White could carry through his attack.) 13...Bxe5 14.Rxe5 Nxc3 15.bxc3 exf5 Black is a pawn ahead and safe against surprises.

13.Qc2 Bb4

 After 13...Qxd4 14.Red1 Qc5 15.Na4 Qb4 16.a3 the Bishop is lost, and though Black could recover the piece by ...b7-b5, his position would be ruined.

14.Rad1 Bxc3 15.bxc3 c5

 By manoeuvring with his Queen and King's Bishop and leaving the Queen's Bishop and Queen's Rook undeveloped, Black has only given free play to White's Rooks. Now, perhaps, resistance would still have been possible, if he had played 15...Bd7 but he misses his last chance in still delaying his development.

White: Dus-Chotimirsky; Black: Cohn


Decisive. If Black does not capture, White does so and enters, without sacrifice, with his Rooks into Black's game.


 After 16...exf5 17.Nxf7 Rxf7 18.Re7 Black would be lost.

If 39...Qd1 40.Kg2 Qxe2 41.Qxe8 Kg7 42.Qe7 and wins Queen or Rook.
