| Dec-08-04 | | aw1988: Terrifying, wouldn't you agree? |
|
| Feb-11-06 | | latebishop: The winning line I thought I found was: 41.Qh2 Qxc3 42.Qh6+ Kh8 43.Qxf8+ Rxf8 44.Rxh7++ Black can't avoid this by moving his knight because this allows 42.Qh6+ and 43.Qxh7++ anyway. |
|

 | | OBIT: After 41. Qh2, it's not easy after 41...Ng6+! 42. Kxf5 Kf8! |
|
| Feb-11-06 | | patzer2: Too bad ChessGames.com puzzles no longer have solutions, since this game continuation for today's (41. ?)appears to be cooked. After the game continuation 41. Rxh7+!? Nxh7 42. Qh2 Nxg5 43. Qg3 Kf8 44. Qxg5, Black can hold with the defensive combination 44...a1Q!! (instead of 44...Qxc3??). Play could continue 44...a1Q!! 45. Rxa1 (not 45. Bxa1?? Qh3+ ) 45...Qxc3 46. Nh7+ Ke8 47. Nf6+ Kf8 48. Nh7+ = with a draw by perpetual. |
|
| Feb-11-06 | | latebishop: Thanks OBIT. I missed the check on g6. |
|
| Feb-11-06 | | patzer2: Perhaps this puzzle has a solution afterall. White appears to have a win after 41. Kxf5! Be2 (41...Ba6 42. Ra1! Bc4 43. Kg4 Rdc8 44. Qc2!  )42. Ra1! Qb3 43. Rxa2 Qc4 44. Qxe2 . |
|
| Feb-11-06 | | dzechiel: I certainly didn't get this one. Pretty messy. I wanted to play 41 ♘xh7, but that doesn't look nearly forcing enough. <sigh> |

| | OBIT: 41. Qh2 Ng6+ 42. Kxf5 may work, but boy it's messy. After 42...Kf8, White appears to have a dangerous attack after 43. e6! Also, 42...Ne7+ 43. Kg4 Be2+ 44. Qxe2 Qxc3 45. Rxh7+ Kf8 46. e6! None of these lines look totally clear (to me, anyway), but Black's king certainly looks more uncomfortable than White's king. Patzer2's suggestion 41. Kxf5!? also looks promising. After 41...Ng6 42. Rxh7+ Kf8 43. e6! - this pawn push appears to be the key move in many lines. |

| Feb-11-06 | | erimiro1: <patzer2>Your analysis was wrong, but your saying - right! Even Smyslov, and later Kasparov, wrote that white could achieve nothing better than a draw! Smyslov gave the correct 42.-Kf8! (much better than 42.-N:g5) 43.Qh6+ Ke7 44.N:h7 as a winning variant, but Kasprov asked later, "But what next? A powerful modern computer finds without difficulty... a draw for white" (the analysis is long so I add only the general evaluations). But black's decisive mistake was on his 44th. move 44.-Q:c3?? (the marks are given by Kasparov, who wrote: "What for? black has an enormous material advantage!"). "Correct was 44.- a1=Q!", writes Smyslov, who, again, achieves nothing but a draw for white. So if 2 champions say something, I tend to accept, and today's puzzle is a problematic one. |
|
| Feb-11-06 | | vmur2000: I dont think the move played was a combination.If Black plays a1Q then e6 R*a1 is forced and it is a draw according to Junior because e6 simply loses owing to R*a1 Q*c3 e6 Q*d4+  . |
|
| Feb-11-06 | | patzer2: <OBIT> More than promising, 41. Kxf5! Ng6 42. Rxh7+ Kf8 43. e6! Rb7 44. Qh2 is clearly decisive. After 41. Qh2 Ng6+ 42. Kxf5 Kf8 43. e6 Qxc3 44. Nxh7+ Ke8 45. Nf6+ Kf8 46. Nh7+! Ke8 47. Nf6+ =, White can force a draw by perpetual but risks losing if he tries for more. |
|
| Feb-11-06 | | patzer2: <erimiro1> Where is the analysis wrong? I noted 44...Qc3?? was a mistake and that 44...a1Q!! = leads to a draw.
I suspect you're contesting my assertion that 41. Kxf5! gives White winning chances, since you state Kasparov has said White can get nothing better than a draw. Looking at this possibility more in depth, I did find 41. Kxf5! Ba6 42. Ra1 Rb3 43. Rhc1 Bc8+ 44. Kf4 Qb4 45. Rxa2 gives White a clear advantage, but isn't yet a forced win. However, it's also not a forced draw either, and it's not at all clear that White can't win here. Would appreciate any analysis proving that Black can force a draw after 41. Kxf5! If Gary Kasparov says it's so, I'm inclined to believe it, but would like to actually see and understand the drawing technique. |
|
| Feb-11-06 | | sagahelten: patzer2: What forces black to play 41... Ng6?? after Kxf5? Fritz suggests the following line: 41. Kxf5 Ba6 42. Ra1 Bc4 43. Nxh7 Rb1 44. Nf6 Rxh1 45. Rxh1 46. Qb3 with little advantage for white. |
|
| Feb-11-06 | | Rastus: I thought that 41. Rxh7 was winning with a forced mate but, as usual, I hallucinated an incorrect continuation. So I consulted Chess Tiger and discovered that ... 44. a1Q saves black, as discussed. So, even if I had found Smyslov's variation (fat chance!) I still would have been wrong? |
|
| Feb-11-06 | | euripides: Another try is 42...Kf8 43 Qh6+ Ke8 44 Ng8+ !? when 44..Rxg8 45 Qd6+ Ke8 46 Qxb8+ Ke7 47 Qxg8 Qxc3 48 Qg1 may be good and 44 ...Kd7 45 Qd6+ mates, but 44...Ke8 seems difficult to crack e.g. 45 Qc6+ Kf8. |
|
| Feb-11-06 | | Eatman: Have to admit I saw Rxh7 quickly but thought that black was escaping with Kf8 instead of Nxg5.
Turns out I was right, but I certainly didn't see a1Q later on. |
|
| Feb-11-06 | | Scarecrow: Well, I for one thought it was 41. Nxh7 Nxh7 42. Rxh7+ Kxh7 (just supposed that Black would take everything) 43. Qh2+ Kg8 44. Rh1 and now 44. - Kf8 is mate in five, so Black has to play 44. - Qc1+ 45. Rxc1 (Rb1 46. Rh1 Rxh1 47. Qxh1 ) (43. - Kg6?? 44. Qh6#, 43. - Kg7 44. Qh6+ Kg8 45. Rh1 and now only 45. - Qc1+ 46. Rxc1 saves Black from mate) Unfortunately, only after a few million nodes even Sigma Chess Lite gives 41. - Ne6+ better for Black. |
|
| Feb-11-06 | | monad: What a mess!
My eye fell on <41.Kxf5> first thing, which <sort of trickles along after 41...Qb3.> For a change I seem to have picked a better one than Mr. Smyslov. But then...to win after such a blunder from Black can't have given him satisfaction, Why did Black blunder AFTER the time limit had been reached? What was the haste for playing 44...Qxc3? |
|
| Feb-11-06 | | erimiro1: <patzer2>You were right, by pointing out 44- a1=Q! to be the saving move for black. I haven't tested today's puzzle, including your 41.K:f5, because I knew it (and its defects). 41.K:f5 was not tried by Kasparov, and as far as I know, by no one else. Kasparov's solution for today's puzzle is: 41.Qh2! and now if 41.-Q:c3?? 42.Qh6+ Kh8 43.Q:h7+ with mate; After 41. Ne6+ comes 42.K:f5 (there it is, your move!) Kf8 (the only move) 43.Q:h7 Q:c3 44.Q:f7+!! K:f7 45.g6+ Kf8 46.Rh8+ Ke7 47.Rh7+ Kf8 48.Rf7#
If: 43.-Ng7+ 44.Q:g7+!! K:g7 45.Rh7+ Kf8 46.e6 Rb7 47.e7+ K:e7 48.Re1+ Kf8 49.Rh8+ Kg7 50.R:d8 Bd3+ 51.Kg4 with mate. Best for black is: 41.-Ng6+. The analysis here continues to move 56, and again, white wins. |
|
| Feb-11-06 | | Fan of Leko: <erimiro1> Qh2 was the move I finally chose, so I guess I solved it, and better than Smyslov! I didn't analyse (quite) as far as Garry, but on the main line our thougths were much the same. |
|
| Feb-11-06 | | EmperorAtahualpa: I only saw the first few moves, the rest was quite beyond my reach! Nice puzzle. |
|
| Feb-11-06 | | dakgootje: got the first moves, but missed blacks Nxg5 |
|
| Feb-11-06 | | Jacobb: I am once again reminded why these guys are masters and i am not. tough puzzle:( |
