|Feb-10-05|| ||cu8sfan: Fascinating ending. 101.♘f2 looks very tempting at first but is a nice stalemate trick. I like the endgame puzzles. Thanks, labbase.com! |
|Feb-10-05|| ||Sneaky: What a weird way for a game to end. It's very easy to see 101.Qh3+ but then you think "Oh, 101...Qh2 is also a check, that will trade queens or something... so that can't be the answer..." Deceptive position.|
By the way, 100...Kf1 101.Nd2+ winning the queen.
|Feb-10-05|| ||who: yeah white had a forced win with the NP game... 87.Kd8!! Kf5 (or h5 h4) 88. Nc5 g4 89. Na4!! (89.Nd7?? draws after 89..Nc8 90.KxN g3 and white can't stop the pawn) 89... Nc8 90. KxN g3 ( If 90...Ke4 Kd7 queens and wins.) 91. Nc3 g2 92.Ne2 and stops the pawn. The sacrifice of the b pawn earns some respect for endgame intuition even if he didn't get it quite right :-) |
|Feb-10-05|| ||greystar69: I, like many others, have also been enjoying the endgame puzzles. They are still chess, but give a breath of fresh air! |
|Feb-10-05|| ||euripides: From move 40 onwards, Golombek tries hard to avoid the exchange of rooks. 59...e4 is surprising, opening a route for White's knight - it might be a response to zugzwang but is there anything wrong with 59..Kf7 ? |
|Feb-10-05|| ||DexterGordon: <cu8sfan>, I'm sure all the folks at fritzbasegamelab.com appreciate your kind words! |
Fwiw, I'm really enjoying the endgame puzzles too.
|Feb-10-05|| ||patzer2: Since August 2003, in addition to learning the difference between <chessgames.com>, chessbase.com and chesslab.com, I've also gained a greater appreciation for endgames and the depth of play involved, such as in this nice win by Yanofsky.|
Yanofsky's passed up the win of a pawn by not playing 24.Rxd8! Rxd8 25.Rxd8 Qxd8 26.Nxe5±. However, he appeared to judge correctly that his winning chances would be greater against Glombek by keeping more pieces on the board and not simplifying so quickly.
However, Glombek erred at moves 23, 76 and 78 in missing equalizing continuations:
23...e5? [23...Rxd4! 24.Nxd4 Rd8 25.Nb5 Rxd1+ 26.Qxd1=]
76...Kxf4? [76...gxf4 77.Kd2 Ne3 78.Kd3 Ng4 79.b4 f3 80.Ne4 f2 81.Nd2 Kd6=]
78...Nc6? [78...Nf3! 79.Nd7 Kf5 80.b4 g4 81.Ke3 Ne1 82.b5 Nc2+ 83.Kf2 Ke6 84.Nc5+ Kd6 85.Nb3 Na3 86.c5+ Kd7 87.b6 g3+ 88.Kxg3 Nc4 89.Kf4 Nxb6 90.cxb6 Kc6=]
After 77. Kd2!, Yanofsky has a won game, but two alternatives, and perhaps simpler wins, that he passed up at move 80 and 91 are worth noting:
80.Ke4! wins but stronger perhaps is [80.c5! Kh4 81.Nd4 Ne7 82.b4 g4 83.Ne2 Kg5 84.b5 Kf6 85.b6 Nc6 86.Kc4 Ke7 87.Nd4 Kd7 88.Nxc6 Kxc6 89.Kd4 g3 90.Ke3 g2 91.Kf2 g1Q+ 92.Kxg1 ]
91.Kb8! wins but a worthy alternative is [91.Kc8! Nd6+ 92.Kd7 Nc4 93.Ne7 Ke5 94.Nf5 Kxf5 95.Kc6! Ke4 96.c8Q ]
|Feb-10-05|| ||euripides: <patzer> intersting lines, though some move-numbering problems. |
Is the position after <[76...gxf4 77.Kd2 Ne3 78.Kd3 Ng4 79.b4 f3 80.Ne4 f2 81.Nd2 Kd6=]> really drawn ? I would have thought that White would win by Ke2-f3.
|Feb-10-05|| ||Timetraveller: <who>: But doesn't Black hold the draw after 87. Kd8, Kh4 (or h5); 88. Nc5, g4; 89. Na4, g3 (instead of Nc8); 90. Nxb6, g2; 91. c8Q, g1Q =. |
|Feb-10-05|| ||kevin86: Again,bravo!! for this one! Note black has the stalemate possibility of 102...♕xg3+ 103 ♕xg3 stalemate}---as you were,the move is not legal!! The only legal move is the march to the scaffold:102...♔g1 103 ♕f1#-no escape-thanks a lot, queen! |
|Feb-10-05|| ||patzer2: <Euripides> After 76...gxf4!, the reply 77. Kf3 levels out after 77...Nd4+! 78.Kg4 Nc6 79.Nd7+ Ke4 80.c5 f3 81.Nf6+ Ke3 82.Kg3 Ke2 83.Nd5 Nb4! 84.Nc3+ (84.Nxb4?? f2 –+) 84...Ke3 85.Nd1+ Ke2 86.Nc3+ Ke3 87.Nd1+ Ke2 88.Nc3+ =, with a draw by threefold repetition of moves. |
|Feb-10-05|| ||euripides: <patzer> I meant Ke2 and Kf3 as a winning plan for White on moves 82-83 in the position that you gave as drawn after <[76...gxf4 77.Kd2 Ne3 78.Kd3 Ng4 79.b4 f3 80.Ne4 f2 81.Nd2 Kd6=]>, not in the position at move 77. Sorry if this wasn't clear;) |
|Feb-10-05|| ||patzer2: <cruzian> Thanks for the link to the endgame tablebase server (I assume you have to register to use it), and the improvement 98...Kf1!(apparently yielding a draw).|
It would seem 80. c5! is White's best option for a forced win, following 79. Ne6+!
|Feb-10-05|| ||beatgiant: <patzer2: <cruzian> Thanks for the link to the endgame tablebase server (I assume you have to register to use it)>|
You don't have to register, but it only works if you enter your position as a FEN string (http://en.wikipedia.org/wiki/FEN) in the form below the chessboard.
|Feb-10-05|| ||patzer2: <euripides> Thanks for clarifying. After your recommended 82. Ke2 in the 76...gxf4! line, it still looks like a draw.|
[77.Kf3!? Nd4+ 78.Kg4 Nc6 79.Nd7+ Ke4 80.c5 f3 81.Nf6+ Ke3 82.Kg3 Ke2 83.Nd5 Nb4 84.Nc3+ (84.Nxb4?? f2–+) 84...Ke3 85.Nd1+ Ke2 86.Nc3+ Ke3 87.Nd1+ Ke2 88.Nc3 ]
77...♘e3 78.♔d3 ♘g4 79.b4 f3 80.♘e4 f2 81.♘d2 ♔d6 <82.♔e2> ♘e5! 83.♘e4+ (83.Kxf2 Nd3+ 84.Ke3 Nxb4=) 83...♔c6 84.c5 ♘d3! 85.♘xf2 (85. kxd3?? f1Q!+ ) 85...♘xb4=
|Feb-10-05|| ||patzer2: <beatgiant> Thanks for the tip on FEN and the site provided by <cruzian>. |
|Feb-10-05|| ||who: <timetraveller> you are absolutely correct. I kept assuming Kf5 was the best move for black in order to limit the white knight's range of motion. but really the king is better off away from the line of check. |
|Feb-10-05|| ||yoozum: Brilliant 100. Qg3...Kh1 101. Nf2 leads to stalemate.|
Alternatively, 100...Kf1 101. Nd2 captures the queen.
Are you guys doing this in your heads or with a board? I am doing the former so as to prepare for OTB play.
|Feb-10-05|| ||euripides: <patzer> yes I don't have a board but that looks convincing. |
|Feb-11-05|| ||Lucky1: My software terminates this game after move 33 due to 3-fold repetition. |
|Dec-28-05|| ||notyetagm: Black resigns since mate is looming by 102 ... ♔g1 103 ♕f1#. Instead of going into the h1-corner on move 100, the Black king could have gone to f1 instead (100 ... ♔f1). But that would have lost the Black queen to 101 ♘d2+ (<REMOVAL OF THE GUARD>) ♔e2 102 ♕x♕ ♔x♘.|
Notice the beautiful queen and knight co-ordination, especially ♘e4/♕g3+ and the mating ♘g3/♕f1#.
The position before Whites's 99th move is The Times Winning Move Puzzle for Wednesday, December 28.
|Dec-28-05|| ||syracrophy: 102...Kg1 103.Qf1++|
|Jan-15-06|| ||hailstone: There's an online tablebase server at http://www.k4it.de/index.php?topic=... which includes the available 6-man tables. (For some reason this site seems to be less well known than others than only go up to 5-man tables).|
So we can get definitive answers from 81 ... Nxb3 onwards. It seems that 91 Kb8 was a mistake, after which black should have drawn (with 98 ... Kf1). Correct was the line given by patzer2 with 91 Kc8! winning.
|Mar-12-13|| ||profK: What a way to loose after hanging in there for so long. 98...Kf1 on spec looks far less risky than 98...Kh2.|
|May-13-16|| ||Penguincw: Looking at this game, I wonder if I would've figured out the win after 98...Kh2. I got 99.Qh4+ Kg2 100.Qg3+. If 100...Kf1, I see 101.Nd2+ Ke2 102.Qxg1, but I missed 100...Kh1 <101. Qh3+> Qh2 102.Ng3+ Kg1 103.Qf1# 1-0. If OTB, black had played 100...Kh1, I would've incorrectly played 101.Nf2+ (101...Qxf2 1/2-1/2).|
