Mar-16-08  zoat22: cgts <dzechiel> for getting the insane puzzle!
Mar-16-08  znprdx: Well this is pretty - I only considered the prosaic 21.e6 However it is a move like 25.Bd3 that leaves one breathless and 29.exf7 blows the mind. What is astounding is to see Karpov destroy Quinteros who was a giant killer himself. Boy these were the good old days....
Mar-16-08  012: Saturday puzzle <16. ...?> Mar-15-08 Chiburdanidze vs E Torre, 1988
Mar-16-08  DarthStapler: I got the first move but I kept thinking e6 instead of Nf5
Mar-16-08  Anatoly21: I got all the way through move 24, and at 25 I played Nh6, at which point I think Bd3 really is bettter. Strange that I got this one but totally missed yesterdays. I really have to get my tactical vision checked out.

  Jimfromprovidence: I wonder if black might have done better with 25...Nc5, not Rg8.

Then what follows could be 26 Nxe7 Nxd3 27 Nxg6+ fxg6 28 cxd3 Qe7.

I don't know if this position is better or worse than the text, or simply just different.

Mar-16-08  chessmoron: Karpov missed 24.Nd4!. If Quinteros accepts the sac 24...Kxh6 than Karpov can play the marvelous 25.Nf6!!
Mar-16-08  johnlspouge: Sunday (Insane): White to play and win.

Material: even. White has much more space. The White Qe2 and Bg3 support the Pe5 spearhead, which in turn supports a superb post for Nd6. The Rd1 is active on a semi-open file, and Ph4 takes the useful defensive square g5 away from Black; Pe5, the square f6. The White Nb3, Bf1, and Rh1 need to be activated. In particular, Qe2 blocks Bf1. Black has no patently loose pieces, but Qc7 is on the same diagonal as Bg3, and Be7 is loose on the same file as Qe2. The only active Black piece is Bd5.

Candidates (20.): Rxd5, Nf5

20.Rxd5 exd5 [else, drop a B]

Candidates (21.): e6, Nf5

21.Nf5 (threatening 22.Nxe7+ or 22.e6) Qd8

22.Qg4 (threatening 23.Qxg7# or 23.Nxh6) g6

The only other feasible Black defenses are 22.Ng5 or 22…Bg5, returning an excess of material, anticipating a long, losing game.

Candidates (23.): e6, Bd3

23.Bd3 (threatening 24.e6 25.exf7+, with complete collapse of the Black position) Kh8

Candidates (24.): Nxh6, e6

24.Nxh6 (threatening to develop the final White piece: 25.Rf1 26.Rxf7)

Black must protect Pf7, but in the Karpovian style, his defensive options have been limited.

(1) 24…Qe8 25.h5 f5

[25…g5 26.Qf5]

[25…else 26.hxg6

and in <kevein86>’s happy phrase, the Rh1 “works from home” on the open h-file to finish Black]

26.Qxg6, and White has a strong attack and 2Ps for the exchange, with the Pf5 ready to fall.

(2) 24…Kg7

Candidates (25.): Nf5+, h5

25.h5, and Black cannot accept the sacrifice of Nh5:

25…Kxh5 26.hxg6+ Kg7 27.Rxh7+ Kg8 28.gxf7#

Thus, White gains a material advantage with 26.hxg6, and his attack rages unabated. Time to peek.

  al wazir: How does white win after 34...g5 ? The best I can see is to bring the other ♘ into the attack. If 35. Re8+, then 35...Nxe8 36. f8=Q+ Nxf8 37. Nf7+ Kg8 38. Nxd8 Rxd8, and black has ♖+♖+♘ vs. ♕+♗.
Mar-16-08  johnlspouge: <<ConLaMismaMano> wrote: Is this an intuition sac (20.Rxd5)? Because i think Karpov saw he had a strong and lasting attack, but not a whole forced combination.>

My analysis appears to show a forced win (equivalent to +1.0 P in an otherwise at least even position). My initial impression of the kibitzing is that I improved slightly on Karpov's play with a transposition of <Hesam7>'s suggestion, although I have not checked the soundness of the transposition with a computer. Given our relative chess, I am willing to hazard that Karpov might have seen the whole combination.

The solutions <dzechiel> and I generated on today's Sunday puzzle more than justify the possibility that <UdayanOwen> might have seen <every move> of a mere Thursday puzzle. In the spirit we have seen, of generously avoiding personal attacks, I would therefore like to make a general comment on the kibitzing in E Vladimirov vs V Vorotnikov, 1974.

People should be encouraged to develop their abilities, not stoned in public for having them.

  al wazir: Ah, I see. If 34...g5 then 35. Bxh7. After 35...Nxh7, 35...Rxh7, or 35...Kxh7 white plays 36. Re8 Nxe8 37. f8=Q+.
Mar-16-08  Stelling: <<Al wazir>> I was about to say that, also there is the nice: 34. ... g5 35. B:h7 K:h7 36. Re8 N:e8 37. f8=Q K:h6 (hoping for a material balance with two rooks and queen against two queens) 38. Qd3 and if 38. ... Nf6 then 39. Q:f6+ Q:f6 40. Qh3+ Kg6 41. Qh5#. I'm not sure if it is 100% accurate but it is really cute. ;) Cheers.
Mar-16-08  johnlspouge: My transposition is inferior. The response to 23.Bd3 is

23...h5 24.Qf4

Toga evaluates the position as [ply 15/41, time 00:13, value +0.91].

Mar-16-08  wals: Noting Think:- Put the greatest attention on those details which will reap you the greatest rewards.

Forward to - TPOTD

Nh7 is only guarded by the King. There must be a point of entry there.How do we infiltrate?

Bf4. Qg4, Bd3 Rd4, ph5, Bh4

all nice moves. Let's try and string a few of them together.

20.Rxd5 ...pxd5 21.Nd4 ...g6 22.Nf5 ... gxf5

23.Nxf5 and there's Qg4+ or Nh3 + to follow.


Yes, that just shows the difference between a 2800 player and a 1200 one.

Mar-16-08  johnlspouge: Nicely done on the key move, <wals>!

But should I be congratulating RB or LB? :)

Mar-16-08  Jason Frost: Bah I got stuck on 21. Nxf7 and after not seeing anything amazing decided to peek. ):
Mar-16-08  MarkThornton: <20. Rxd5!> is a fine move, but it is a long-term strategic sacrifice. This is a strange choice for a tactics puzzle.
Mar-16-08  whiteshark: <MarkThornton>...but I wouldn't call <22.Qg4> a strategic move. :D
Mar-16-08  TrueBlue: saw it, a little too easy for a Sunday. Still think the Friday puzzle was the hardest.

  Honza Cervenka: I guess that 10...Nxe4 is no good. 11.Bxe7 Nxc3 12.Qxc3 Kxe7 13.Qxg7 wins the Pawn back with interest.
Mar-17-08  malvar: Insane:
I suspect a tactical blow in the center and perhaps trying to clear eventually blacks g pawn, giving up quality. They are both equal in material.

20. Rxd5 seems the more logical to me... exd5 21. Nf5 perhaps? Leaving the e pawn advance for a later moment, attacking blacks remaining bishop; maybe the black bishop will end up in e5 mating. How?... is the question. I have trouble seeing it clearly. I'll take another look.

Mar-17-08  malvar: this is a great puzzle! I had somewhat the general attacking plan, but even further along the way, I also found it hard to see the continuations in move 31. loved it! Have a great week friends!

  kevin86: A wild chain of moves leads white to a quick win.
Jun-04-08  ezmerin: It's Karpov's typical game. They might put it in glass cover and leave in Sevres to show the spectators how to strangulate opponent in python's way.

It's true Black Knight had no good square to flee from f6, but he might try 15...Ng8!?

Aug-03-17  Everett: <Mar-16-08 chessmoron: Karpov missed 24.Nd4!. If Quinteros accepts the sac 24...Kxh6 than Karpov can play the marvelous 25.Nf6!!>

It seems your 24th is an improvement, yet the best follow-up is likely <24.Nd4 Kxh6 25.h5> and Black is in a tough spot
