|Jun-07-06|| ||jaime gallegos: this game deserves a mention !|
|May-13-07|| ||dozewhat: excellent mating attack by Makarichev|
|May-13-07|| ||chessmoron: Tough one. I don't think I can provide the lines even someone tell me 15.Nxe6 to start with.|
|May-13-07|| ||Alphalegacy: incredible attack|
|May-13-07|| ||MostlyAverageJoe: Impossible. I completely agree with <chessmoron>.|
Anyone waiting for Monday puzzle, feel free to check out an easy one I just posted on The Kibitzer's Café
|May-13-07|| ||MostlyAverageJoe: BTW, here's a huge blunder by the black: 24 ... Qa3?? allowing a forced mate in 9 or less (I did not run full anaylysis here). 25.Qa6 has accelerated the demise.|
24 ... Qc5 would let him struggle for a bit longer.
|May-13-07|| ||fictionist: darn! what a sunday this is!|
|May-13-07|| ||dzechiel: A complex position with lots of candidate moves. Right off the bat I would consider:|
- 15 Nxf7
- 15 Qh5
- 15 Qf3
- 15 Nxe6
- 15 Bxd5
- 15 exd6
Most of the above moves are "forcing" in the sense that they severly limit black's replies.
Of the above moves, the two that get my attention are 15 Nxe6 and 15 exd6. I think it's possible that both of these moves are played, but I'm not certain in what order.
What about 15 Nxe6 fxe6 16 exd6 Bxd6 17 Qxe6+ Be7 18 Bg5 Qc7 19 Rfe1, does this work? The threat is 20 Bxd5 followed by 21 Bxe7. How many of black's moves are "forced"?
- 15...fxe6 is necessary to avoid losing material, and the white knight on e6 keeps black from castling (it also threatens the g7 pawn).
- 16...Bxd6 must be played or allow 17 Qxe6+ and the e7 square is covered by the white pawn.
- 17...Be7 is forced or give back the material and white is a pawn up with a better position.
- 18...Qc7 keeps the bishop on the board after white plays 19 Bxd5.
So can it be that easy? Time to check the game and see.
|May-13-07|| ||dzechiel: Close! I should have realized that black would have some better options. Looking forward to Monday.|
|May-13-07|| ||jmrulez2004: goodness...this is so fantastically hard...after the first two moves i was completely lost....i saw the move Nxe6...but it was my second move..i was thinking bout exd6 as the first move..wow..this game..mind blowing!!!|
|May-13-07|| ||dzechiel: <jmrulez2004: i saw the move Nxe6...but it was my second move..i was thinking about exd6 as the first move>|
I also considered both 15 Nxe6 and 15 exd6. The reason I chose Nxe6 to play first is because if you play 15 exd6, then black has the option of playing 15...Bxg5 which then makes the sac on e6 impossible.
|May-13-07|| ||mvnonup08: It's going down in my favorite games collection...I probably would have played Ne4 in this white's position.|
|May-13-07|| ||simsan: <MostlyAverageJoe> And interestingly, my computer thinks that after 24. ... Qc5 the non-trivial 25. Re5 is the correct reply (exploiting the fact that the bishop is required to protect e7).|
|May-13-07|| ||farrooj: How deep do the variations i find have to be to claim that i solved this puzzle?|
|May-13-07|| ||AugustAle: Claim Victory for trying! How about 15.exd6..first?|
|May-13-07|| ||openingspecialist: Ok heres my thoughts. I havent looked at the solution yet. Origonally I thought exd6 but BxN BxB Nd7 is drawish. Then I looked at Nxe6. Then fxe6 seems forced as if not exd6 and very bad not even needing calculation. So Nxe6 fxe6 exd6 anyway. Bxd6 or else Qxe6+ or not+ and mate follows. Qxe6+ and blocking is force or else QxB+. So either Ne7 or Be7. Ne7 then QxB and white is up a pawn with a double bishop attck where castling isn't possible. Note if Qxb2 Bg5 wins through Qxe7# or if Nd5 either Rook Checks Kf7 Re7+(N pinned) Kf8 or g8 and Qe8#. So Be7 Bg5. BLack has several responses but the Bishop needs protecting as BxN and Qxe7#. Nf6 is a possible move then maybe Rfe1. Looking at it at the moment BxN could solve Nmoves problems if i see them. Rfe1 at the moment. Bishop needs protecting again except Qf7+ is a new threat. Qc7 looks best. Now white really needs a good combination to win at least the peice back. Bf4 looks tempting but maybe not winning. Lets explore it Qd7 only move. Queens off the board doesnt look good for white so Qf7+ Kd8. Ive missed something back to Nxe6 fxe6 exd6 Bxd6 Qxe6+ Be7 Rfe1 prevents Nf6. Qc7 or d8 c7 for the moment. Bg5 Nf6 same position. Bf4 must have been bad. Right now Bf7+ would be handy. Bxf6 gxf6 Qf7+ Kd8. Doesnt look too good. d5 maybe Be6 maybe. d5. The threat is opening the d file and black is gone. I know Nxe6 fxe6 exd6 Bxd6 Qxe6+ Be7 d5 now. Qd7 oh this ruins it. d6! not yet. Now fritz or HIRAICS would be handy. The bishop looks lost cause after Qxd6 Qf7+ and Bxf6 wins. The B and Q are both goners. So after d6 QxQ RxQ and the bishop is lost. 0-0 RxB+ Kh8 BxN gxN (RxN Re8 mates) Bd3. Black is lost. So 0-0 loses, what else is there? Nbd7 Rxe7+ (I think rook on the 7th in an endgame is winning in a position like this one.) lost for black so QxQ loses. That brings us back to Qc7 is a bad move. Wow this is big analysis. So Nxe6 fxe6 exd6 Bxd6 Qxe6+ Be7 Rfe1 Qd8. Damn my heart skipped a beat at Bb4 but Nx. so Bg5 Nf6 d5. So d6 is the threat. cxd5 oh no my line is ruined. Ok this line not d5 Qf7+ Kd7 Be6+ Kc7 oh damn. ok not Be6 d5 instead. ok if Nxd5 hmmm Rad1 looks good yeah if Rf8 Qe6+ Kc7 Bxe7 and black is lost. So not Kc7 Ke8 Bxe7 anyway. Qxe7 Qc8+ Kf7 RxQ+!!. Ok i think ive done enough even too much analysis. I could be way off I'm checking the answer now.|
|May-13-07|| ||openingspecialist: Damn i missed Bf6. By the way dxe6 imediately only draws after Bxg5|
|May-13-07|| ||HelaNubo: I think that one could easily see 15. Nxe6 fxe6 16. exd6 Bxd6 17. Qxe6+ Be7 18. Rfe1 with strong attack; if the bishop does not retake the pawn (as in the actual game) White has 2 pawns for a piece and a really strong attack. I saw this, and I dare say that Makarichev did not see all lines until 27. Qe8+;-)
So I claim that I have got it;-)|
|May-13-07|| ||openingspecialist: I pitty Alburt. How could you calcualte a attack such as this in such little time. I am horrified that things like this can happen to you. The pawn on c4 was clearly piosened though. A 1000er doesnt leave them let alone a GM.|
|May-13-07|| ||Skylark: I noticed the combination beginning with 15. Nxe6 led to continuing initiative for white but I'm not a supercomputer; I couldn't calculate it through. I pretty much looked at it for a while, decided that it "felt" good (since taking the pawn on d6 is practically suicidal for black) and then decided I would play it. I was right but in a game I wonder if I would have really played it based on a "feeling". Unfortunately for me, the answer is probably not..|
|May-13-07|| ||PinkCat: <simsan> more interestingly, after 24..Qc5 25Re5 Qxf2+ 26Kxf2 Bxe5+ looks playable!|
|May-13-07|| ||PositionalTactician: Hmm, interesting. It is impossible to calculate everything to the end in this game. I guess White is playing Tal-like chess. He is confident with his abilities to see further than his oppoent. |
However, White does seem to get a lot of dangerous activity for the sacrificed piece!
|May-13-07|| ||tallinn: Interesting. Read on, new puzzle inside. Although I managed to win this position against Fritz I had no clue what is really going on most of the time.|
Starting with the obvious Nxe6 fxe6 exd6 Fritz reply Bf6 wasn't so unexpected but uncalculated as almost anything happening now and further: Qxe6+ Kd8.

The key position. Fritz shows me a big green bar indicating that white has won. But how? Without anything forcing I looked at blacks best piece Nd5 and decided to take that out. Now Fritz is kind: Bxd5 Nd7!?. Uups? Thank you, Fritz, for not asking me to show that after cxd5 Rac1 Nc6 there is something for white in the position (in fact there is, see below, but for the time being I did not know). Now white's play is easy enough for me: Bf3 Re8 Qf5 g6 Qc2 Kc8 Rfe1 Rd8 Qa4 Bxd4 Ba5 Bxf2+ Kh1 Qd4 Qxd4 Bxd4 Bxd8 Kxd8 Re7 .
The line Nxe6 fxe6 exd6 Bxf6 Qe6+ Kd8 Bxd5 cxd5 Rac1 Nc6 leads to another puzzle. Qf7 is the only winning move for white here (really, really hard to see). Fritz continued in that line with Rc8 Rfe1 Nb8. Now what is white's best move here? Something better then Qxd5?

24 ... Qc5 would let him struggle for a bit longer.>|
Even after the superior 24...Qc5, White still seems to have a forced win, as follows: 25.Bd1 Qd5 26.Qe7+ Bxe7 27.dxe7+ Ke8 28.exf8Q+ Kxf8 29.Re8+ Kf7 30.Bb3 .
|May-13-07|| ||Fezzik: First things first here: This was played in 1978 before any computer could begin to calculate the possibilities of a position such as this|
For me, the question is how far ahead would Makarichev have to see in order to decide whether to make the sacrifice.
I think (though I have no way of proving it) that Makarichev's sac was almost purely positional in nature.
He saw that he was ahead in development and that Black's king was still in the center of the board. With that in mind, he saw a way to keep the attack going with only a minimum of material sacrifice.
For the meager price of a Knight for 2 centralised pawns, White could open up the game for his pieces and guarantee a long term advantage. This isn't *puzzle* material so much as *practical* material.
Makarichev's brilliance was not in seeing twenty moves deep, it was in sensing the possibilities of his developed side versus the limited chances for Black. Essentially, Black was playing 1-3 pieces down due to White's sac.
I saw as far as Qxe6 and figured White must win. Whether I would have had the courage to play this way in a tournament as important as the USSR Championship is another matter.
Kudos to Makarichev and Chessgames for providing us with such a brilliant *positional* sacrifice! (If a computer finds a flaws in the follow-up, I still consider it sound because of the long-term nature of White's advantage.)
