Schlechter - Lasker

St Petersburg 1909

Ruy Lopez

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.O-O d6 5.d4 Bd7 6.Nc3 Be7 7.Re1 exd4 8.Nxd4 O-O 9.Nde2 a6 10.Ba4


 The retreat 10.Bd3 appears stronger. It is true that Black can then change the White King's Bishop for a Knight, by playing, say 10...Ne5 but in that case White would retake with the c-pawn and would have two strong pawns in the centre as compensation for Black's two Bishops.

10...Re8 11.f3 h6

 If Black played 11...Bf8 at once White's reply would be 12.Bg5 threatening 13. Ne5. After this Black would have nothing better than 12...h6 13.Bh4 Be7

12.Be3 Bf8 13.Qd2 Ne5

By this move Black frees his game.


 It was not good to retire the Bishop. White ought to have exchanged 14.Bxd7

14...c5 15.Bd5 Rb8 16.Nf4 b5 17.a3 Nxd5 18.Ncxd5 f5

The point of Black's strategy. After the exchange of the e-pawn the weakness of his d-pawn does not signify.

19.exf5 Bxf5 20.Bf2 Qd7 21.Ne3 Bh7 22.Nfd5 Qf7 23.Rad1 Nc6 24.Bg3 Rbd8 25.Bh4 Rd7 26.Ng4 Rxe1 27.Rxe1 Nd428.Nge3

 White dare not reply 28.Nde3 as 28...g5 29.Bg3 h5 would get him into difficulties.

28...Bxc2 29.Nxc2 Nxc2 30.Nf6 gxf6 31.Qxc2 f5 32.f4 Bg7

32...d5 33.Re5 d4 and, whether Queen or Rook take the f-pawn 34...d3 would have decided the game at once.

33.h3 c4 34.g4

A desperate attempt to obtain an attack.


Simply 34...fxg4 35.hxg4 followed either by 35. ..Qxf4 or 35...d6 was indicated.

35.gxf5 d4 36.Qe4 d3 37.f6 Bf8

If37...Bxf6 38.Bxf6 Qxf6 39.Qe8

38.Kh2 d2



 Better 38...Kh8 39.Rg1 a5

39.Rd1 Qh5

39...Kh8 was still the right move. If White plays 40.Qe2 then 40...Bd6 41.Kg3 ( after 41.Qxd2 Bxf4 42.Qxf4 Rxd1 43.Qxh6 Kg8 44.Qg5 Kh7 White's checks would cease and Black should win. ) 41...Qg6 42.Qg4 Bxf4 and wins.

40.Qe6 Kh8 41.f7 Qxf7 42.Bf6

 Far better than at once 42.Qxf7 as White's b-pawn is saved from attack by the exchange of the Bishops.



 To 42...Kh7 the reply would not have been 43.Qf5 ( but 43.Qxf7 Rxf7 44.Bc3 and White would have taken up a strong defensive position. ) 43...Kg8 44.Rg1 as after 44...Bg7 45.Rxg7 Qxg7 46.Bxg7 d1=Q 47.Kg3 Black would get out of the checks and win.

43.Qxf7 Rxf7 44.Bxg7 Kxg7 45.Rxd2 Rxf4 46.Kg3 Re4 47.Kf3 Re1 48.Rd7 Kf6 49.Rd6 Ke5 50.Rxa6 Rb1 51.Rxh6 Rxb2 52.Ke3 Rb3 53.Kd2 Kd4 54.Rd6 Kc5 55.Ra6 Rxh3 56.Ra8 Rh2 57.Kc3 Ra2 58.Rc8 Kb6 59.Rb8 Kc6 60.Ra8 Kc5 61.Rc8 Kb6 62.Rb8 Kc6 63.Ra8 Kb7 64.Ra5 Kb6 65.Ra8 Kc6 66.Kd4 Kb7 67.Ra5 Rd2 68.Kc3 Rd5 69.Kb4 Kb6 70.a4 c3 71.axb5

After 71.axb5  if  71...c2 then follows 72.Ra6 Kb7 73.Rc6

1/2 - 1/2
