Perhaps 33.Qf3 was best, avoiding the exchange of Queens. Or 33.f5 Qe5+ 34.Kh1 Rc1+ 35.Rd1 Qb2 36.Qd3 Rxd1+ (36...Bxa2?? 37.Qd8+ Kg7 38.Qxg5+ Kf8 39.Rxc1 wins for White) 37.Qxd1 Bxa2 38.Qd8+ Kg7 39.Qxg5+ draws. Or 33.fxg5 Qxg5 34.Bf3 Qf4+ 35.Kg2 Rc3 36.Rd8+ Kg7 37.Rd3 should draw. If 35.Rxf4, then 35...Bxa2 36.Rf1 Be6 37.Kg3 a2 38.e5 Rc3+ 39.Kf4 Rb3 40.Be4 Rxh3 should win. If 37.Bxf3, then 37...Rb8 38.e5 Rb2 39.Kg3 Bxa2 40.Be4 Rxf2 41.Kxf2 Bc4 42.Bb1 a2 43.Bxa2 Bxa2 44.Ke3 Kf8 should win. If 37.Rxf3, then 37...Bxa2 38.Rf1 Bc4 39.Ra1 a2 40.e5 Ra3 41.h4 Be6 42.g5 Ra4 43.h5 Rb4 and 44...Rb1 should win. If 38.Kg3, then 38...Rb2 39.Rxf3 Rxa2 40.Bg2 Ra1 41.Rd3 a2 42.Ra3 Rc1 and 43...a1=Q If 40.Bg2, then 40...Ra1 41.Rd3 a2 42.Ra3 Rc1 and 43...a1=Q After 40...Ra1, if 41.Bc4 Bxc4 42.Rxc4 a2 43.Ra4 Rg1+ and 44...a1=Q |

I'm studying 38. Bd3 Rd8, for example then 39. Bf1 Rd1 40. Rxf3 Rd2+ 41. Kg3 Rxa2, etc. Any opinion? |
|
Jan-09-06
| | Calli: <beatgiant> Happy 2006! 38.Bd3 Rd8 39.Ba6 and if 39...Rd1 40.Bb7 followed by Bd5 is good for White. |
|
| Jan-11-06 | | beatgiant: <Calli>
Then following your original <38.Bd3! Rb2 39.Rxb2 axb2 40.Bb1>, and then 40...Bc4 41. Kg3 Be2 42. a4 Kf8 43. a5 Ke7 44. a6 Bxa6 45. Kxf3 Kd6 46. Ke3 Kc5 47. Kd2 Kb4, etc. wouldn't Black eventually win the bishop for the b-pawn? What am I missing? |
|

| | Calli: <wouldn't Black eventually win the bishop for the b-pawn?> You would think. I must have looked at it a half dozen times over the last couple of years and never could say Black definitely wins. On 40...Bc4 41.Kg3 Be2 best is 42.g5 and then if 42..Kf8 43.Kf2 Ke7 44.a4 Kd6 45.h4 White has chances of eliminating the Black pawns. Would be great if you can prove something because I get always lost somewhere in there :-) |

<Would be great if you can prove something because I get always lost>Very flattering if you think I can find something you missed. But let's start from the end of your line: 38. Bd3 Rb2 39. Rxb2 axb2 40. Bb1 Bc4 41. Kg3 Be2 42. g5 Kf8 43. Kf2 Ke7 44. a4 Kd6 45. h4:
click for larger viewAt first glance, Black can chase off White's bishop and queen the b-pawn: 45...Kc5 46. Ke3 Kb4 47. e5 Kc3 48. Bxh7 Bd1 49. Bb1 Bc2 50. Ba2 Kb4 51. a5 Ka3 52. a6 Kxa2 53. a7 Be4 54. Kxe4 b1=Q+ followed by ...Qb7 etc. Black queens first and then stops the a-pawn. This kind of line is why I assumed White had to free his king by immediately pushing the a-pawn as in my previous post. |

| | Calli: <Beat> you're right. I probably remembered it wrong. Lets advance the a-pawn faster. 38. Bd3 Rb2 39. Rxb2 axb2 40. Bb1 Bc4 41. Kg3 Be2 42. g5 Kf8 43. a4 Ke7 44. a5 Kd6 45. a6 Bxa6 46.Kxf3 looks drawish? |
|
| Apr-11-06 | | beatgiant: <Calli>
Thanks, your latest line seems to settle the draw.
What I missed was after 38. Bd3 Rb2 39. Rxb2 axb2 40. Bb1 Bc4 41. Kg3 Be2 42. g5 Kf8 43. a4 Ke7 44. a5 Kd6 45. a6 <Kc6> (my intended try), White has good enough counterplay after 46. e5 Kb6 47. Bxh7 etc. I have not found any win for Black. |

| | Calli: <beatgiant> Hi! Since we last discussed this game, Karsten Müller pointed out in Chess Note 4193 that "Capablanca’s 36...f3 was, in fact, a mistake, violating the important endgame principle “do not hurry”. Improving the position of the rook and king first and playing ...f3 later to disrupt White’s defensive coordination should win. For instance, 36...Ra4 37 g5 Kg7 38 h4 h6 39 gxh6+ Kxh6, and White is powerless against Black’s plan of bringing the rook to b2 and infiltrating with the king (e.g. 40 Bf3 Rb4, followed by ...Rb2)." I missed it completely. He is saying that 36...f3 allows the later exchange fo the a pawn and delaying it allows the black king into the position. |

| Apr-12-06 | | beatgiant: <Calli>
I think Black does still have at least some winning chances in the line you posted earlier:<38. Bd3 Rb2 39. Rxb2 axb2 40. Bb1 Bc4 41. Kg3 Be2 42. g5 Kf8 43. a4 Ke7 44. a5 Kd6 45. a6 Bxa6 46.Kxf3 looks drawish?> And then 46...Ke5, hoping to use the outside passed pawn to harvest the kingside. For example, 46...Ke5 47. Ke3
Bc4 48. h4 Be6 49. h5 Bg4 50. h6 Be6 seems to leave White in zugzwang. |

| | Calli: Maybe go after the b pawn?
38.Bd3 Rb2 39.Rxb2 axb2 40.Bb1 Bc4 41.Kg3 Be2 42.g5 Kf8 43.a4 Ke7 44.a5 Kd6 45.a6 Bxa6 46.Kxf3 Ke5 47.Ke3 Bc4 Then
48.Kd2 Kf4 49.Kc3 Be6 50.h4 Kg4 51.Kxb2 Kxh4 52.e5 Kxg5 53.Bxh7 draws |
|
| Apr-13-06 | | beatgiant: <Calli>
It's much more tricky than I thought, but still Black looks good after your<38.Bd3 Rb2 39.Rxb2 axb2 40.Bb1 Bc4 41.Kg3 Be2 42.g5 Kf8 43.a4 Ke7 44.a5 Kd6 45.a6 Bxa6 46.Kxf3 Ke5 47.Ke3 Bc4
48.Kd2> and now 48...Kd4 49. e5 Bd5 50. Bxh7 Ba2 looks like it wins the bishop without allowing White to trade off all the pawns. |
|

| | Calli: <beat> play h4 first and make Black's king capture on h4. 48...Kd4 49.h4 Bb3 50.e5 Bd5 51.Kc2! Be4+ 52.Kxb2 Bxb1 53.Kxb1 Kxe5 54.Kc2 Kf4 55.Kd3 Kg4 56.Ke4 Kxh4 57.Kf4 draws |
|
| Apr-15-06 | | beatgiant: <Calli>
You are right, it's a draw. So that leaves us with <Karsten Müller>'s try.But I'm not sure I understand Black's winning plan after a line like 36...Ra4 37 g5 Kg7 38 h4 h6 39 gxh6+ Kxh6 40 Bf1 Kh5 41 Kg2, etc. |
|
Apr-15-06
| | Calli: <beatgiant> Its still difficult. After 36...Ra4 37.g5 Kg7 38.h4 h6 39.gxh6+ Kxh6 40.Kg1 (40.Bf1? Rxe4) I don't see anything active for White at this point. Keeping the rook at f2 at least lets him play Rxf4+, if Kxh5 and also Rf3 to attack the a3 pawn if Black plays Rb4 40...Kh5 41.Kh2 Rb4 42.Rf3 Rxe4 43.Rxa3 Re2 threatens Bd5 44.Kg1 threatens Bf3+ 44...Kxh4 45.Rf3 Kg4 threat of Rxg2+ 46.Ra3 again Bf3+ 46...Rd2 finally threatening Bxa2 47.Bh3+ Kh4 48.Bxe6 fxe6 should win |
|
| Apr-04-07 | | yunis: 34.....f3 35.Bf1??why not to take on f3 ? i see nothing impending! |
|
| Apr-10-07 | | beatgiant: <yunis>
On 35. Bxf3 Rb8, and the impending doom is ...Rb2 winning the a-pawn and probably soon winning a piece. |

 | | King Sacrificer: I just played this game in Guess The Move. It was very hard for me to guess Capablanca's plan here. It looked like White had the material advantage with no serious positional weaknesses in the midgame. It's fun to watch moves after 27...f3. Brilliant endgame technique. |
