|Mar-29-03|| ||Rookpawn: In his book on the Zurich 1953 tournament, Bronstein says after 13... Bd7, "Thus, the black bishop can find no fulcrum from which to exert its leverage, and wanders mournfully along the diagonal c8-h3: it has taken three moves to get from c8 to d7!" In fact, the bishop "wanders mournfully" on that same diagonal for the entire game until it is exchanged off. |
|Sep-27-04|| ||JohnSilver: In the same book Bronstein also wrote, that Black would not survive even after 50. ...Kb7. He analyzed:
51. Rh2 R:a7 52.R:h4 Kc6 53. Rh6 Rf7 54. Rh8 Re7 55. Kd4 Rf7 56. Rg8 with zugzwang. But what about 54. ...Kd7(with intention Re7-e5)?
If 55. Ra8 then 55. ...Re7, e.g. 56. Ra7+ Ke8 57. R:e7 K:e7 with draw.
If 55. Kd4 then Rg7 e.g. 56. Ra8 Rg1.
Can anybody help?
|Sep-27-04|| ||Cyphelium: <JohnSilver> After 50.- Kb7 51. Rh2 Rxa7 52. Rxh4 Kc6 53. Rh6 Rf7 54. Rh8 Kd7 55. Ra8 Re7 56. Ra7+ Ke8 57. Rxe7+ Kxe7, is it really a draw? 58. Kb5 and now if white can reach c6 with his king, it's over. Black seems unable to stop this: 58.- Kd7 59. Kb6 loses the d-pawn and the desperate 58.- d5 59. exd5 Kd6 60. Kc4 Ke5 61. Kc5 loses as well. |
|Sep-28-04|| ||Cyphelium: <JohnSilver> I have to correct myself here. 58.- Kd7 59. Kb6 is just nonsense: 59.- d5! 60. exd5 Kd6 gives black the opposition and he even...wins! So white has to settle for 60. Kc5 dxe4 61. Kd4, which looks drawish at best. So you are right after all, it's probably a draw. |
|Sep-28-04|| ||clocked: <JohnSilver> after 50...Kb7 why not 51.Kd5 |
|Sep-30-04|| ||JohnSilver: Cyphelium & clocked thank you for your replies. After 50...Kb7 51. Kd5 White seems to win. I asked myself whether 50...Kb6 is an improvement, for example:
51.Kd5 R:a7 and then
1)52. R:a7 K:a7 and h4 queens;
2)52. Rh2 Re7 53. R:h4 Kc7 54. Rh6 Kd7 55. R:f6 Re5+ 56. Kd4 Ke7 with draw(?);
3)52. Re2 Re7 53. K:d6 Re5 with draw(??), I mean the white rook has to defend e4 and the white king has no possibility to attack f6.
Looking forward for your replies.
|Sep-30-04|| ||JohnSilver: Therefore I've suggested 50...Kb6 instead of 50...Kb7. |
|Sep-30-04|| ||clocked: <JohnSilver> sorry, I skipped ahead. I like your idea as the king cant even swing around due to d5. |
|Sep-30-04|| ||clocked: If this line is a draw, then in your first suggestion the rook can ignore the f-pawn and go directly to e5 via 53....Re7 instead of f7 |
|Jun-14-09|| ||Chessical: Stahlberg had two opportunities to draw this very educative ending according to Euwe.|
Euwe stated ("A Guide to the Chess Endings") that <43...f6> should have drawn. For example, he gives, <44.a6> g5 45. f5 h4 46.
gxh4 gxh4 47. Ke4 h3 48. Kf3 and now <48...d5>. This appears, however, to be an error as after <49.Kg3> Kd6 50. Kxh3 Ke5 (so far Euwe) <51. Kg4!> wins <51...Rg7+> 52.Kf3 Ra7 53.Ke3 d4+ 54.Kd3 Kxf5 55.Kxd4 Ke6 56.Kc5
Instead, in the above line, <48...Kc6> is a draw <49. Kg3> Kb5 50. Ra1 Rxa6 =
Euwe also shows that <48...Ra7> should have given "excellent" chances of a draw to Stahlberg.
<49.a6 Kc6 50.Kd4 h3 51.Kc4 h2 52.Rxh2 Rxa6 53.Rh6 Ra4+ 54.Kd3 Kc5 55.Rxf6 Ra3+ 56.Kd2 Kd4 57.Re6 (<57.Rxd6+> does not work after the straightforward <57...Kxe4> 58. f6 Ke5 59. Rb6 Rf3 =) <57... Ra2+> 58. Ke1 d5! 59.e5 <Ke3!> the mate threat saves Black thus: <60.Kd1> d4 61. f6 d3 62. Rc6 Rf2 63. Kc1 d2+ 64. Kc2 Ke2 65. Rd6 Ke1
|Jun-14-09|| ||WhiteRook48: nice ending|
|Jan-20-15|| ||plang: 5..d6 was new; 5..Qa4+ 6 Nc3..Ne4 7 Qd4..Nxc3 8 Bd2 led to an advantage for White in Euwe-Nestler Dubrovnik 1950 (if 8..Qxd5 9 Qxc3). 22..Bxb3 23 Nb6..Bxd1 24 Rxd1 would have been winning for White. 23..Nfe8 looks like an improvement not sacrificing another pawn. 31..Nc7 avoiding the exchange of light-squared bishops would have been a better defense for Black. Bronstein offered the variation 44 Ra2..f6 45 Ra3..g5 46 f5..h4 47 gxh..gxh 48 Ke4..h3 49 Kf3..h2 50 Kg2..Kc6 with a win for White but Smyslov pointed out that the improvement 48..d5+ 49 Kf4..Kd6 50 Kg4..Ke5 with a draw. Dvoretsky thought Black still had a path to a draw had he played 51..Kb6 52 Kd5..Rxa7 53 Rh2..Kc7 54 Rxh3..Ra5+ 55 Ke6..Re5+ 56 Kxf6..Rxe4.|
