| Jul-22-09 | | tivrfoa: I think g6 works too (but Qxh7+ is better).
53. g6 fxg6

55. Rh1 Nxe4+

57. Bf3 ? (doesn't matter)

Did you overlook the fact that white is down a piece? Black "could" give the piece back with 53...Nxd6 or 53...Rxd6. But resisting to give the piece back looks much better. For example, 53...Nhf6 54.Rh1 Kf8 55.Qh8+ Ng8. |

 | | kevin86: This one was TOO easy;I was looking for some ddep combination-not a queen sac followed by a round up ending in a pawn mate. |

 | | YouRang: Right idea, wrong order:
I saw 57.Qxh7+ Kxh7 58.Rh2+ Kg8 59.Rh1 f6, but here I lazily figured 60.g6 finished off the mating net. Unfortunately, it allows 60...Kf8!, and now 61.Rh8+ Qg8! and black wins. :-( |
|
| Jul-22-09 | | The Rocket: very nice finish by karpov in this game... calculating that this leads to inevitable mate is not too hard |
|
| Jul-22-09 | | BlackWaive: I spotted the solution in nearly 10 minutes, which is a bit long for a Wednesday-caliber puzzle. Most of my attention was directed to 53. Rh1 since many variations give White an easy mating attack, such as 53...Rxb2?? 54. Qxh7+ Kf8 55. Qh8#. However, I later discovered that 53. Rh1 Rxd6! eats the pawn that locks Black's king into the back rank, preventing any back rank mating attacks after ...Kf8. Since White is already a piece down, regaining the piece with 54. Qxh7+ was probably not enough. Searching for faster ways to take advantage of Black's back rank weakness, I eventually found 53. Qxh7+! After 53...Kxh7 54. Rh1+ Kg8 55. Rbh2, White's mating attack succeeds because Black's king is on g8 instead of f8. |

| Jul-22-09 | | doubledrooks: After missing yesterday's puzzle, I seem to have rebounded today. I found 53. Qxh7+ Kxh7 54. Rh2+ Kg8 55. Rdh1 and black can't wriggle out of mate. For example: A. 55...f6 56. Rh8+ Kf7 56. g6#
B. 55...g6 56. Rh8+ Kg7 57. R1h7#. |
|
| Jul-22-09 | | Summerfruit: Black is a knight up.
White mates as follows:
53.Qxh7+ Kxh7 (Kf8 54.Qh8#) 54.Rh2+ Kg8 55.Rdh1
a) 55...f6 56.Rh8+ Kf7 57.g6#
b) 55...g6 56.Rh8+ Kg7 57.R1h7#
c) 55...(any other move) 56.Rh8# |

You missed, for example:
54...Nef6.
<once> Happy birthday.
Indeed this puzzle has 2 solutions. Rh1 works, great job. Hard to see this, I missed. |
|
| Jul-22-09 | | blacksburg: ouch. one of those moves that makes your ears ring when played against you. |
|
| Jul-22-09 | | Slurpeeman: Once again, I am tempted to break the monitor w/ a keyboard. For God's sake, CG, get it straight! Queen sacs were Mondays only, so i didn't even consider Qxh7. Plan the puzzles out accordingly, and you will save chess fans tons of frustration. I went for 53. Rc2, and on the offer to exchange queens I planned Qh2, then pushing the Black Queen away from the defence of back rank, and later g6 fxg6. fxg6 and then bring over the rooks. Please, please tell me 53. Rc2 is not losing |

| Jul-22-09 | | TheBish: Karpov vs Ribli, 1986 White to play (53.?) "Medium/Easy"
White is down a piece, but has an incredible attack going. White could win the piece back with 53. Rh1 Rxd6! 54. Qxh7+ Kf8, but is down a pawn, and it's a passed pawn. But there is much better. 53. Qxh7+!!
The trick is to attack on the h-file, but with tempo! 53...Kxh7 54. Rh1+ Kg8 55. Rbh2 and Black gets mated after either 55...f6 56. g6, or 55...g6 56. f6 Nxf6 57. gxf6, and Rh8# is coming. |

53. Qxh7+!!
53...Kxh7 54. Rh1+ Kg8 55. Rbh2 and Black gets mated after either 55...f6 56. g6, ...> Heh. Welcome to the Blewit club.
56.<g6?> Kf8! 57.Ra8+ Qg8!  |

| Jul-22-09 | | MiCrooks: I almost jumped at a less forcing alternative again today after yesterday's Nc6/Rd8 fiasco, I saw the problems Black had with his King and thought that Rh1 left him pretty well dead, except that he is already a piece up, so he can simply play Rxd6 giving himself some much needed luft and run for the hills! Since I was looking at the end of the day (i.e. after work rather than during!) I spent a second more and realized that it WAS just Wednesday and that the Queen sac was much more forcing and indeed was forced mate! Not sure about people who would play g6 rather than Rh8+...really over the board you would play a waiting move rather than a forcing one that leads to mate? I give you more credit that that...you may have sort of had the idea that whichever pawn got pushed you could maintain the mating net, but I for one give you credit that over the board, facing the situation at hand you would not pass up the check at h8 and play g6 losing...so give yourselves credit!! :) |
|
| Jul-22-09 | | TheBish: <YouRang> Heh. Welcome to the Blewit club. I wouldn't say I "blewit". I just rushed in my answer, since obviously the immediate check with 56. Rh8+ mates next move (see game). I remember seeing this game once upon a time (what Karpov game featuring a queen sac wouldn't be well known?). So gloat if you must, bellringer, but I saw the rook check first forced mate, just tried to simplify my answer (and spent more time explaining myself than if I had given separate lines!). By the way, there is no 57. Ra8+. |

| Jul-22-09 | | uaregg: I think it was just too easy for a wednesday |

| | YouRang: <TheBish> Well, I could hardly be gloating since I made the same mistake myself. And yes, I meant 57.Rh8+. Fortunately, it's the sort of mistake that might be forgiving. That is, back on move 53, you play <53.Qxh7+> having (incorrectly) calculated that you'll win with <53...Kxh7 54.Rh1+ Kg8 55.Rbh2 f6 56.g6?>. However, all the moves are correct up until you play your 56th move, and by that time, you might notice your mistake and (after a brief moment of panic) notice that you can still win with <56.Rh8+ Kf7 57.g6#>. Then you just act like you had it all worked out correctly the whole time. |

| Jul-22-09 | | beatgiant: The early kibbitzing on this page by <karlzen> <apr 27 04> is fascinating. Whatever happened to him? |
|
| Jul-22-09 | | AuN1: saw it from a mile away. |
|
| Jul-22-09 | | Utopian2020: By trying to recover a lost pawn with 47...Qxb4, Ribli set in motion a series of moves that quickly led to his downfall. 47...Nd6 holds off Karpov's attack allowing black time to consolidate his defense. |

| Aug-07-10 | | percyblakeney: <The early kibbitzing on this page by <karlzen> <apr 27 04> is fascinating. Whatever happened to him?> Considering the level of his analysis I wouldn't be surprised if he just won against Anand: <After 4 hours and 23 minutes, Anand finished his simul and his final score was 36-4: +34-2=4. He lost two games: one against Henrik Karlzen from Sweden> http://www.chess.co.uk/twic/chessne... |

| Dec-16-11 | | King Death: These Hedgehog lines had to be one of the worst things to play against Karpov for even a strong GM. |
