|Dec-14-03|| ||kevin86: 20 years ago-and he's still darn good!
The♕ vs ♖ is not nearly as bad as ♕ + ♙ vs ♕ or ♖ + ♗ vs ♖
|Dec-14-03|| ||Dick Brain: If you can win any of these against best play than you're a lot better than I am. |
|Dec-14-03|| ||Eggman: ♕ vs ♖ is worth studying: ♖ endings are the most frequently occurring endings, and ♖+♙ vs ♖ or ♖+♙ vs ♖+♙ will sometimes lead to ♕ vs ♖. If you know the basic ideas and memorize a couple of crucial positions it is really not such a difficult ending. |
|Dec-14-03|| ||Dick Brain: I recall Walter Browne was not able to beat a computer programmed for the first time to play Q vs R endings perfectly in the required 50 moves. Browne then put in some serious study in these endings and on the rematch was able to beat the computer, but just barely because the capture of the computer's room came on the 50th move.|
|Feb-26-04|| ||seeminor: This game is weird. both sides seem to play one good move followed by a not so good one, it is fairl equal up until move 30 the the errors start! For example whites 30. Nxd5?! misses two equal continuations (30.Nc5 or Nb4 lead to equality), however by Kasparov playing 33..Rb3! Black has an advantage. Korchnoi compounds this by playing the weak 36.g4? (missing the strongest 36.Rg5! g6 37.h5)Yet on Kasparovs 37th move...Rcc3?! he returns the favour, and then makes a worse error 39..b4?, missing Rxd3! leading to a strong advantage(40.exd3 Bxf4 41.Ke2 Rb2 42.Kf3 Bd6 43.Rh8 Kd5 44.Ke3 Rg2!-+)Korchnoi equalizes with 41.exd3=. The really tough endgame is finally won when Korchnoi plays 63.d5? missing Kasparovs Rg6+!. this game probably made Korchnoi realise that Kasparov had more than attacking prowess, his endgame skill was excellent too. |
|Feb-26-04|| ||drukenknight: yea, this Q v R stuff is not easy. Capablanca devoted a short passage to it in one of his books. He showed a technique for winning, but it's impossible to say it's good for all endings like this. Let alone those w/ an added pawn. |
|Feb-26-04|| ||drukenknight: If you guys liked that Q v Rook endgame, what about this one? A Q v R ending that no one knew existed! |
Spassky vs Fischer, 1972
|Oct-05-05|| ||acaling1000: Instead of an enterprising 54.Ke5? 54.Kd5! draws. E.g. 54.Kd5!-Rc8 55.Rc8-b1=Q 56.d6-Qd3 57.Kc6 is a draw. I challenge everyone to prove me wrong.|
|Mar-05-06|| ||numcrun: I dunno why Korch resigned, it is far from easy to win in the final position.|
|Mar-05-06|| ||Benzol: <numcrun> To me it looks like Kasparov will soon win Korchnoi's Rook.|
After 78.♔f8 ♔g5 the Rook doesn't have many squares to flee to.
The Black King covers h6,h5,h4 and f6 the Black Queen covers h7,h3,e6,d6 and c6.
If 79.♖h2 then ♕d6+ forks the White pieces and the Rook is lost.
If 79.♖h1 then ♕c8+ 80.♔moves and 80...♕b7+ again forks and wins.
If 79.♖b6 or 79.♖a6 then either 79...♕d8+ or 79...♕c8+ and again the fork wins the Rook.
If 79.♖h8 then 79...♔g6 80.♖g8+ ♔f6 and White cannot avoid mate.
|Jun-07-06|| ||KingG: Here's an old N.Y Times article on this game: http://query.nytimes.com/gst/fullpa...|
|Jun-07-06|| ||keypusher: Thanks <kingG>!|
|Jun-08-06|| ||hitman84: <KingG>great thanks!|
What a game by the great GAZZA!
|Jun-08-06|| ||MrMelad: why not 12. Bxd5 ?|
|Jun-08-06|| ||borisbadenoff: <MrMelad: why not 12. Bxd5 ?> Are you serious? How about 15. .. Nbxd5 or 15. .. Nfxd5|
|Jun-08-06|| ||KingG: <borisbadenoff> What are you talking about? He said 12.Bxd5, not 15.Bxd5.|
<MrMelad> The problem with 12.Bxd5 is it severely weakens the light squares around White's king, and since Black still has his light squared bishop, things could become dangerous for White. Additionally, he probably can't hold on to the pawn anyway.
For example, after 12.Bxd5 Nxd5 13.Qxd5 Nxe5 14.Qxe5 Bf6 15.Qe4 Bh3, and now White has problems with his king, and his extra pawn is under attack. Even if White can hold on to the pawn, Black has more than enough compensation: two bishops in an open position, better development, White's weak light squares, ... It's all bad for White.

Easy man. I made a misread can happen to anyone can't it?|
|Jun-09-06|| ||goldenbear: Korchnoi is undoubtedly guilty (I say this without computer aid so if I'm wrong... sue me) of not seeing in front of his nose. Obviously (to me), with 15.Nb5! White has an enormous, probably insurmountable, advantage. That move does so many things for White that I can't believe it wasn't played here. I'm dumbfounded. Am I missing something?|
|Jun-09-06|| ||euripides: <golden> if 15 Nb5 I think Black can play 15...Bf5. Now if 16 Nc7 Rac8 and White may have trouble saving the knight e.g. 17 Rc3 Bd6 18 Rac1 Na2. If 16 Rc7 axb5 17 Rxa8 Rxa8 18 Rxe7 Ra1+ 19 Bf1 Bh3 Black wins. White no doubt has something better but it doesn't look terrific for him.|
|Jun-09-06|| ||goldenbear: <euripides> In your line, I think White has to play the sharp 17.g4 with, apparently, a roughly equal game. Consideration of that line does lead to the conclusion that 15.Bd2 (threatening Nb5) is probably the best move. However, 15.h3 (also threatening Nb5) comes into consderation as well. In that case, the reply 15.Bf5 looks to me like runs into 16.Rc7. This is all a bit complicated but maybe Black has already equalized.|
|Jun-22-06|| ||MrMelad: Though late - thank you <KingG> it was informative.|
|Feb-23-08|| ||Bodia: According to endgame tablebases 63.Rd1 and draw.|
|May-21-15|| ||Jonathan Sarfati: <Dick Brain>, Goldsby's page is helpful in principle, but his analysis is definitely pre-tablebase. Run his positions through http://www.k4it.de/?topic=egtb&lang...|
|Sep-16-17|| ||Albion 1959: I recall at the time that move 63.d5 was the losing move and that Rd1 would have drawn. There was plenty of analysis to support this, but I wonder if this is correct today ? Now that there are powerful search engines that could probably play this ending with more precision, maybe it was still a win for black ? This was a turning point in the match. Korchnoi was leading at the time, but with this win Kasparov levelled the match, gained confidence and went onto crush Korchnoi to win easily in the end:|
|Sep-17-17|| ||beatgiant: <Albion 1959>
Tablebases confirm, with mathematical certainty, that 63. Rd1 is a draw and 63. d5 loses.
