 | | FSR: <Eduardo Bermudez> Only eight? By my count he's beaten Smyslov, Tal, Petrosian, Spassky, Karpov, Kasparov, Kramnik, Anand, and Khalifman at classical time controls, and Ponomariov in rapid games. That's ten, or nine if you only count classical games. |

| Nov-14-20 | | landshark: I saw the idea and got the first move right but not the follow up:
19..... Qxe3+?
20.Kf1! and now if ....e4???
21.Bc1
1-0 |

Nf3 Qxe2#) Bg3+ 24. Kf1 Qf2#. No, I didn't see all of that ahead of time. But I don't suppose that Beliavsky foresaw the next 60 moves after 19...e4. |

| Nov-14-20 | | agb2002: White threatens Qxd5.
The convergence of the queen and dark square bishop on h2 suggests 18... Nxe3 19.fxe3 e4 (19... Qxe3+ 20.Kf1 with the threat 21.Bc1): A) 20.dxe4 fxe4 21.Nxe4 (21.Nd4 Qxh2#) 21... Qxe3+ followed by Qxe2 or Qxe4 seems to win a pawn at least. B) 20.Nd4 Bxh2+ 21.Kf1 (21.Kh1 Bg3+ 22.Kg1 Qh2+ 23.Kf1 Qh1#) 21... Qxe3 22.Bh5 (22.Ke1 Bg3+ 23.Kf1 Qf2#) 22... exf3 wins (23.Bxe8 Qg1#; 23.Qxd3 Qg1#; 23.Nf3 Qe2#; 23.Ne2 dxe2+ and mate next). C) 20.Bxg7+ Kxg7 21.Qc3+ Rf6 only seems to lose a bishop. |

| Nov-14-20 | | Walter Glattke: Looking at the first page I see a change on e3 and an interference to Be2,often played in Sicilian with white against black.
18.-Nxe3 19.fxe3 Qxe3+ 20.Kh1? wins, 20.Kf1 Nd4 21.Bd4 exd4 22.Re1 Bxh2 but then no way. 22.-Qh6 23.h3 Bg3 would work. This is all BLITZ.
Stockfish plays 19.-e4, threatens Qxh2 or exf3. nice. 19.dxe4 fxe4 20.Nc5xe4, here i see the "positional qualitity sacrifice" with 20.-Rxf3 21.Bxf3 Bxh2+ 22.Kf1 Qxe3 23.Bxg7+ Kxg7 24.Qc3+ Qxc3 25.Nxc3 with glattfishly +0,5 for white. Another idea was 21.Qc3 exf3!? 22.Qxg7+ Qxg7 23.Bxg7+ Kxg7 costs a piece,
so 18.-Nxe3 19.fxe3 e4 20.dxe4 fxe4 21.Nxe4 Qxe3+ 22.Kf1 Rxe4 or 22.Nf2 Rxe4 wins at least a pwwn and positional advantage. That's the puzzle solution, have a nice day, chessfriends! |

| Nov-14-20 | | Muttley101: <al wazir: Surely 53. Rh3+, winning the last white ♙, would have won immediately.
And why didn't white play 68. Rxh3 ?>
The whole game is instructive, but the rook ending is well worth studying- thank you for asking these questions. <1) Surely 53. Rh3+, winning the last white ♙, would have won immediately.> I suspect you mean 53 ... Rh3+. The position on the board after 52. R:b5 is drawn whether black takes off the a-pawn or not, but that's not going to stop Beliavsky trying to win it. By the principles of endings and rook endings in particular, black wants to activate the king, advance the pawns and stop white's king getting in front of his. This is black's only winning plan as far as I can see. The a-pawn is not dangerous and it would only be worth taking at this point if the resulting position was winning. Promoting the a-pawn would require supporting the pawn with the king to win black's rook for it, by which time black would be so far advanced white could not stop both pawns. So ironically, leaving the pawn on complicates white's defensive task because white may think the pawn is going to help draw. In fact, the position later goes from drawn to lost when Kramnik choses to defend the pawn with his rook instead of staying active with the rook. Key learning point (1): king activity and advancing pawns is crucial in rook endings. Key learning point (2): the a-pawn is not required in this position for white to draw. <2) ... why didn't white play 68. R:h3?> In this position white is already lost whatever he plays, but just like the a-pawn was not dangerous in the previous answer, nor is the h-pawn here. White hopes to make the a-pawn sufficiently dangerous that he can prevent black from queening the f-pawn. Key learning point (3): white is trying to defend a lost R&P ending by using the a-pawn for counterplay. Key learning point (4): knowing how not to get into a lost ending from a drawn ending would be more useful. Rook and pawn endings are the most common endings in chess. Well worth spending some time studying. There are three areas, in order of amount of content and difficulty - general principles, common R+ many P endings, and how to win or draw specific endings. If you have never looked at the literature on R+P endings it is well worth it. Quite apart from there being many excellent books, the chronology of the literature is a great snapshot of how the understanding of chess has evolved. |

| Nov-14-20 | | Brenin: Thanks, <Muttley101>, useful comments. In this game the strategic manoeuvring of the early R&P endgame is at least as interesting and instructive as the tactical skirmish of the puzzle. If players spent more time studying R&P endgames instead of learning opening variations, they would benefit greatly. With the prevalence of quick finishes, it's important to understand basic principles when there's insufficient time to calculate precisely. Here it's interesting to see Black ignoring the a-pawn and advancing his K+2P. |

 | | OhioChessFan: Pretty lame stalemate try at the end of a brilliant beatdown. Seriously, Kramnik? |
|
| Nov-14-20 | | Muttley101: Thanks <Brenin> I've played a lot of rook and pawn endings, including in sudden death/quickplay finishes. Examples include winning a R+P ending a pawn down against a 2100, and more to the point, knowing when we reached it was lost for me and how white should win it. I studied endgames more than openings as a junior. |

| Nov-14-20 | | Messiah: <chrisowen> How do you generate these comments? |
|
| Nov-14-20 | | Muttley101: Thanks <Brenin>. This one is one of the hardest I've seen in recent times (starts at move 39): Caruana vs Carlsen, 2018 But endgames with multiple passed pawns are just crazy. There are a lot of great examples. Karpov winning with his pawns only on one side of the board against Hort is a great technical example. Karpov's rook endings are stellar. Starts at move 27. Karpov vs Hort, 1979 Incidentally, earlier I should have been clearer- for learning point 1, I should have said "activate the king and support advancing passed pawns". Just pushing pawns ain't gonna cut it :D |

|
| Nov-14-20 | | Walter Glattke: Inn a book of Löwenfisch-Smuislov from the 60ies, there are many rook endings and 10 general rules, after I read this I would play in the mysterious move 53 then 53.-Ra2 54.Ra5 h4, so the rook must be behind, the king near to own or enemies pawn, and the king is stronger near, the rook stronger as far-working figure. Try my ending moves here, you can learn more about rook endings, so also Kramnik and Beljavsky should do, at least for this position after 53.Rxb5. |

| Nov-14-20 | | thegoodanarchist: As so often happens at this level, a deep and complicated combination leads only to the win of a pawn. |
|
| Nov-14-20 | | thegoodanarchist: <FSR: <Eduardo Bermudez> Only eight? By my count he's beaten Smyslov, Tal, Petrosian, Spassky, Karpov, Kasparov, Kramnik, Anand, and Khalifman at classical time controls, and Ponomariov in rapid games. That's ten, or nine if you only count classical games.> Instead of only counting classical, what if you don't count Khalifman? His WC title was only achieved due to a rather farcical decision by FIDE. |

| Nov-14-20 | | King.Arthur.Brazil: I guess that Black could play: 24...♗xh2+, then:
A. 25. ♔xh2 ♖xf2 26.♘g5 h6, or
B. 25. ♔f1 ♖c2, since White cannot answer 26. ♗xg7+? ♔xg7 27. ♘xh2 ♖fxf2+. So, after 26. ♖ac1 ♖xc1 27. ♖xc1 ♗g3 and Black is 2♙ ahead.
Next, White could answer 30.♖e1 (Black would not move 30...♗d7? 31.♗d4!) 30...Re7 31. Bd4 Nf5 32. Rxe7 Bxe7 33. Bxa7 b6 34. Bb8 Bd6 35. Ne4 . I feel White has drawing chances. Therefore 30.♗d4 seems premature. Losing this opportunity, White game kept inferior. Also 34.♗xf6? is a strategical mistake. Obviously, it is impossible 45. ♘xf6?? ♔e7... wins the ♘. I'm certain that Black complicated his game risking to draw. After, 61.♖b1 ♖xa3 It could follow: 62. ♖b4+ f4 63. ♖b8 ♖a2+ 64. ♔f1 ♔g3 and White are in zugswang:
C.65.♖b3+ f3 66. ♖b1 ♖h2 67. ♔g1 f2+ 68. ♔f1 ♖h1+ win the ♖ or
D.65. ♖g8+ ♔f3 66. ♔g1 h3 67. ♖h8 ♖a1+ 68. ♔h2 ♔f2 69. ♖xh3 f3 70. ♖h8 ♖e1 71. ♖f8 ♖e2 72. ♔h1 ♖e3 73. ♔h2 ♔e1 74. ♔g3 f2+ 75. ♔g2 ♖e2 76. ♔h1 ♖e7 77. ♔g2 ♖g7+ 78. ♔h1 f1=♕+ End. |

| Nov-14-20 | | stacase: <Messiah: <chrisowen> How do you generate these comments?> Not mine to answer, but it is fairly easy in Microsoft's Excel to generate nonsense random strings of letters, numbers, symbols, and words as a way to generate passwords. Useful formulas in Excel are =rand() and =VLOOKUP(), combine results using =[...]&[...]&[...] etc. |

| Nov-14-20 | | devere: Nice combination to win a pawn, but the rook ending was a tablebase draw up to move 59 https://syzygy-tables.info/?fen=8/8... |
