May-05-07  realbrob: After more than 1 hour and a half it actually came to nothing, the line is 23.Bc6 Qxc6 24.d5 Qxc4 and the score is always (0.33), a slight advantage for White who has attacking possibilities but must be very careful because he's down 2 pieces.. It seems that after all 23.gxh5 and 23.Qg6+ were better than 23.Bc6.

<MostlyAverageJoe> I agree with you, this looks like the Ragozin vs.Boleslavsky game, in which Boleslavsky thought "this can't be the solution, it's too easy", tried to mix things up, and lost.

I think that puzzles with a "true" solution are more enjoyable!

May-05-07  siu02jm: I seriously don't see anything(for white) after 23..Nxc6.

23. Bc6 Nxc6 24. Qg6+ Kh8 25. gxh6 Rg8
26. Qf6+ Kh7 27. h5 Qe7
*

May-05-07  siu02jm: oops! sorry. i c it.

23. Bc6 Nxc6 24. gxh6 Kh7 25. Rg1 Rg8
26. Rxg8 Kxg8 27. O-O-O
* Some people hav suggested 24..Qxc6, I refute it thus: 23. Bc6 Qxc6 24. d5 Qxc4 25. Qg6+ Kf8
26. Rh3
*

May-05-07  TrueBlue: 23. Bc6 Qxc6 24. d5 Qxc4 25. gxh6 Qg4
26. O-O-O Rf8 27. h7+ =

am I missing something?

May-05-07  realbrob: Well, the line you posted is the main line, but the problem is that after 27.h7+ Kxh7 (forced) 28.Qxf8 the evaluation is ± rather than = .

Black's pieces (apart from the Q, which might be exchanged soon) are completely out of the game, the Black king is exposed, the White rooks are very active and White has a very strong passed pawn on h4. So maybe I must apologise to Mr.Makarichev because also 23.Bc6 can lead to a win, but I still think we weren't supposed to see the whole line and that White could reach a decisive advantage more quickly with 23.gxh5, but I haven't checked it yet.

May-05-07  ycsidney: very poor puzzle
May-05-07  alshatranji: 23. Bc6 Qxc6
24. d5 Qxc4
25. gxh6 Qg4
26. O-O-O Rf8
27. h7+ Kxh7
28. Qxf8 Qg7
29. Qf3

Who is better?

May-05-07  realbrob: After <29.Qf3> the position is even, but White can play 29.Qxg7 Kxg7 30.Rdg1+
May-05-07  alshatranji: After <29.Qf3> the position is even, but White can play 29.Qxg7 Kxg7 30.Rdg1+

I see. I think after 29.Qf3 Black my have the advantage; he has more material and I think he can escape White's attack with careful defense. But the line you posted does seem better for White. Looking at "29.Qxg7 Kxg7 30.Rdg1+", it seems that the passed paw gives White the edge. So this could be the answer, the holy grail of this puzzle. Glad I selected 23. Bc6.

May-05-07  iccsumant: what should I do if the pieces and the moves are not appearing? There is a green light there saying some strange things. Please help me out.
May-05-07  Fisheremon: <alshatranji: The best moves for the two sides after 0-0-0 seem to be 26...Rf8, 27. h7+ Kxh7, 28. Qxf8 Qg7, which doesn't look very good for White. Any suggestions anybody?> 29.Qxg7+ Kxg7+ 30.Rdg1+ Kh7 31.Rg5 with next Rhg1 and White's active rooks decide the game.
May-05-07  TrueBlue: people are arguing about move 30, and the puzzle asks for move 23, something is fishy :) I went for 23. Qh6, which gives 2 passed pawns that are much easier to exploit! Much better move IMHO!

  playground player: OK--who got all the moves of this puzzle, from 23 to 65?
May-05-07  Dowell318: <OK--who got all the moves of this puzzle, from 23 to 65?>

Me. Got it in 5 seconds.(Yawn) Need a challenge.

May-05-07  Fezzik: My first thought was that 23.Qg6+ was the best move because I could always repeat the position one more time before finding out if Bc6 was necessary.

Looking at the game continuation, I am sure there are many places that Black could have improved but White was always in charge.

This is the most fun position I've seen in quite a while here, and I will definitely be spending bunches of time analysing this game.

Thanks, Chessgames, for bringing us this game! If the game continuation holds water, this could be one of the greatest games from the 1980s. (At the time, Andrei Sokolov was one of the very best players in the world and would soon be successful in the Candidates tournaments.)

May-05-07  newton296: If u got this 1 i'll put u up there with karpov himself !! I did't even have a clue after looking at it for 5 minutes! and I bet sergey himself was as surprised to win this one as anyone! lol! side note; interesting way to play the open against the nimzo.
May-05-07  newton296: whites's snappy looking 10)h4! offering the bishop to pry open the h file and mate soon follows ! than the sak on move 14)nxf7!! totally opening up the kingside so the q can invade and white always has perp+ to buy time to think . And than another sak of the bishop to bring up the rooks ! 1 -2 -3 punch and sokolov must be dazed and confused at this point !? It must have felt very strange to play this game! how white got the ending figured out to a win is amazing also. white has to be precise to win the rook vs n+b endgame that resulted.
May-05-07  newton296: Only u got all the moves from 23 to 65 playground player! your a animal!
May-05-07  actionhero56: like we can see 40 moves ahead, dumb puzzle...
May-05-07  DeepThought: Is this puzzle to difficult for computers to understand? Rybka sees nothing for White after

17 01:41 15.940.528 166.800 0.00 23. ... Qd7xc6 24.Qf6g6+ Kg8h8 25.Qg6xh6+ Kh8g8 26.Qh6g6+ Kg8h8 27.Qg6f6+ Kh8g8 28.Qf6g6+ Kg8h8 29.Qg6f6+ Kh8g8 30.Qf6g6+

May-05-07  Marmot PFL: Found 23.Bc6 without too much trouble (and I'm no Karpov), but didn't think the ending was winning. Still white was a piece down anyway so this had to be best.
May-05-07  Crowaholic: GNU Chess loses to 23. Qxh6 Re7? (..Qg7 seems much better) 24. h5 Ba6? 25. g6 Rf8 26. Qg5 Rf5 27. Qg3 Bxc4? 28. h6 Qe8 29. e4 Rb5 30. Bf3 e5 31. g7 Kh7 32. Bh5 Bf7? 33. Rg1 etc. but that probably says more about GNU Chess than anything else. :-/

  gawain: Oh, that's a good puzzle! Even if there's a better move for W than 23 Bc6! there isn't a prettier one.

  kevin86: A nice combination-but what does it really gain? White has a rook and two pawns for a bishop and knight. Not exactly a rock-crushing advantage! The following play gains white a winning ending--not the combination itself.
May-06-07  MostlyAverageJoe: <iccsumant: There is a green light there saying some strange things>

Oh, no, too many details. Could you be a bit less specific, please?

<what should I do if the pieces and the moves are not appearing?>

Seriously, now, make sure you have Java enabled in your browser's preferences. If still nothing happens, change Java Viewer at the bottom. If you're using Internut Exploder, switch to Firefox.
