| Feb-02-16 | | kevin86: A nice finish! The queen is sac-ed and the adverse king chased to his doom! |
|
| Feb-02-16 | | psmith: <gilmoy> Looking at this with a computer, I find that 27.... Nxh2+ does make a difference, though not in the game line. The comparison to make is between: 27....Nxh2+ 28. Kf2 Ng4+ 29. Kf3 Qe6 30. Bc1 h5! (threatening Bxd5+) and
27... Qe6 28. Bc1 h5 29. h3.
The former is winning for Black. The latter is not so clear. |

 | | Honza Cervenka: <ISeth: Extremly wonderful but this Sac of Nf2 is an Idea of Bobby Fischer's game.> With all respect to Bobby Fischer, and with all admiration to the gem like Robert E Byrne vs Fischer, 1963, the sac of a Knight on f2 or f7 can be hardly claimed as Bobby's patent. It was played with different tactical motifs in follow-up many times before, like for example in J Bauer vs Harmonist, 1889, Loman vs G Marco, 1906, Flamberg vs Bogoljubov, 1914, Yates vs Marshall, 1925, P F Johner vs M Lowcki, 1912, Unzicker vs Filip, 1955 or with opposite colours Chigorin vs Schlechter, 1899, Burn vs P F Johner, 1906, Tartakower vs Schlechter, 1909, Chigorin vs Przepiorka, 1906 or Botvinnik vs A Batuev, 1930 to show some more or less famous predecessors. |

| Feb-02-16 | | Gilmoy: It helps, of course, to know all of the above sacs :) This particular game also evokes other sac "themes": - <skewer follow-up>: After f2/f7 sac, a diagonal skewer (esp. Bc4+/Bc5+) to deny the retreat, forcing the K-hunt: M Krasenkow vs Nakamura, 2007, <21..Qxf2+ 22.Kxf2 Bc5+ 23.Kf3> Kupreichik vs A Planinc, 1970, <13.Bxf7+ Kxf7 14.Qb3+ Kg6> Here, Zvjaginsev's <stage-2 sac 25..Rxe3> used enticement rather than skewer to pull the K forward. - <moat>: Trapping the enemy K <in front of> a line-mover:
Polugaevsky vs Nezhmetdinov, 1958, <24.Rh1 Rxf4!!> a cat who walks through walls <25.RxQh2 Rf3++> also skewering d2 <26.Kd4>.
This works (when it does) because your pawns become mate threats, which can replace 2-4 pieces. In this game, it was worth Q+N(!) just to establish the moat. White is up almost 4 bishops' worth in material, but <none of them can block> a pawn mate. |

| Feb-02-16 | | schnarre: ...Classic Queen sac, with the opposing King painted into a corner on the opposite side. Fine sacrificial tactics here! |

| Feb-02-16 | | morfishine: OOH, AAHH |
|
| Feb-02-16 | | FairyPromotion: <Cheapo by the Dozen: The initial rook sacrifice was surely speculative.> It might seem so, but it was not. Starting from move 24 all of blacks moves were the best ones in the respective positions. <Phony Benoni: Such constructions are based on Euwe vs Alekhine, 1935, known as <The Pearl of Zandvoort> and the Mother of Pearl games everywhere. They are intended to describe a beautiful game -- perhaps most beautiful -- ever played at that place.> Come to think about it, Wijk aan Zee is the ultimate venue for immortals. Being hailed as the pearl of Wijk is a considerably more prestigious feat than being the pearl of Poznan, Zandvoort, Sochi, Sofia, etc. Of the top of my head I can recall at least 10 games that are all-time top 100'ish, and I'm pretty sure that I'm leaving some other brilliancies out: Beliavsky vs Nunn, 1985, R Cifuentes vs V Zvjaginsev, 1995, Ivanchuk vs Shirov, 1996, Kasparov vs Topalov, 1999, Karjakin vs Anand, 2006, Topalov vs Aronian, 2006, Shirov vs Radjabov, 2007, Topalov vs Kramnik, 2008, Caruana vs A Giri, 2012, Aronian vs Anand, 2013. |

 | | PawnSac: < mrknightly: what happens after 21.BxN RxB 22.Nf5...? >
click for larger view You seem curious about a couple points; first, how does black best answer the mate offer (gxf5?? Qg5+ Kh8 Qg7#) and second, does black still have an attack? After the initial moves you suggested (21.Bxe4 Rxe4 22.Nf5)..
black obviously can't take the knight immediately, but he can try
a different tactic to pull the Q off the dark diagonal. One possibility
is Rxe2 23. Qxe2 gxf5
click for larger view If white continues the mate attack, black has sufficient defensive resources..
24.Qh5 Ne5 (or ..Qd8 +1.5) 25.Qg5+ Ng6 26.Qf6 Be5 (+2.38) 27.Qxf5 Rd8 28.f4 Bg7 (not ..Bd4?? Rxd4 cd Qf6) 29.Bxg7 Kxg7 In this line, the value of ..Ne5 becomes clear. Additionally, if played immediately on move 22 ..Ne5 threatens Nf3+ forking K and Q,
which takes priority. After 23.Kg2 black can then play ..gxf5 and if Qg5+ black again has ..Ng6 Here is the Stockfish 6-64 analysis:
36/64 28:54 1,222,437k 705k +3.16
Ne5 23.Kg2 gxf5 24.f3 Nxf3 25.Kxf3 f6 26.Bf4 Rae8 27.Bxd6 Qxd6 28.Nf4 Rd4 29.Qc1 Bxd5+ 30.Kf2 Bb7 31.Qc4+ Rxc4 32.Rxd6 Rc2+ 33.Kg1 Rxb2 34.Rd7 Bf3 35.Rf1 Be4 36.Rfd1 Rb1 37.Nh5 Rxd1+ 38.Rxd1 Kf7 39.Rd7+ Re7 40.Rd6 c4 41.Rxf6+ Ke8 42.Rd6 c3 43.Nf6+ Kf7 44.Nxe4 fxe4 45.Rxa6 the line ends here, but it is more than clear
that after 45. ..Rc7 the pawn is unstoppable. |
|
| Feb-02-16 | | thegoodanarchist: IMO 24...Nxf2 is reminiscent of this famous game:
Robert E Byrne vs Fischer, 1963 |

However we both remembered the same famous game, which exemplified the tactic. |

|
| Feb-03-16 | | Shams: <luftforlife> Welcome to the site. I like your nick. Bit strange seeing that avatar not attached to User: Strongest Force (who I think uploaded it) but I'm sure you'll take good care of it. |

| Feb-03-16 | | luftforlife: <Phony Benoni>: So do I!
<Shams>: Thank you. I sure will. |

| Jan-30-17 | | BobbieM: Wow, one of the greatest games in history only has four pages of comments! |
|
| Jun-30-24 | | BxChess: I think the puzzle should be 24. ...? |
|
| Jun-30-24 | | mel gibson: I didn't know.
Stockfish 16.1 chooses a different ply and is calling it a draw: 24. h4
(24. h4 (1.h4 a5 2.a3 Rc8 3.axb4 cxb4 4.Qa4 Qxa4 5.Rxa4 Bc7 6.Kg2 Bb6 7.Raa1 Rcd8 8.Bg5 Bxd5 9.Bxf6 Nxf6
10.Bxd5 Bxe3 11.Bxf7+ Kxf7 12.Rxd8 Rxd8 13.fxe3 Ra8 14.b3 Ne4 ) -0.05/53 292) score for White -0.05 depth 53.
if I force SF to play the game ply :
24. Bg2 Nxf2
(24. .. Nxf2 (1. ... Nxf2 2.Kxf2 Rxe3 3.Kxe3 Ng4+ 4.Kd2 Nxh6 5.Rf1 Ng4 6.Rae1 Nxh2 7.Rg1 Qg4 8.Kc1

+3.72/42 307)
score for Black +3.72 depth 42. |

 | | Teyss: Of course it should be 24... Black to play as pointed out by BxChess. Of course I didn't see the combination.
Of course if I had and looked at the line played by White (which apparently is not the best), I would never have spotted the splendid 31...Qe3+!! BTW 31...? would be a great mid-week puzzle, if CG get the colours right. |

| | Teyss: Looking at this pearl again after my morning coffee, if 26.Kxe3 Ng4+ 27.Kd2 Nxh6 as per <mel gibson>, Black has B+P vs R but the advantage of the Bishop pair, domination of the Black squares and threats against the exposed WK. And it would have deprived us of the final fireworks. 
click for larger viewA key move is 29...Qe6! In their book of greatest Chess games, Burgess, Nunn and Emms give the following variations: (a) 30.Qe4 Qxe4+ 31.Kxe4 Re8+ [32.Kmoves Nxe3] wins 
click for larger view(b) 30.Qd2 Re8 31.Nf4 Bxd5+ 32.Nxd5 (32.Qxd5 Nh2+ 33.Kf2 Qxe3#) Qe4+ wins 
click for larger view(c) 30.Bg5 Re8 is similar to the game.
(d) 30.Bc1 (threatening 31...Bxd5+ and 31...Bc5) c4 31.Qe4 Qxe4+ 32.Kxe4 Nf2+ 33.Kd4 Nxd1 wins

"AH!" |

Jun-30-24
| | Teyss: PS: on the 31st move, if White wants to keep protecting both c4 and e2 with 31.Qd2, Bxd5+ 32.Qxd5 Qxe2# Probably he was still hoping to hold and didn't see 31...Qe3+!! |

SO THE GAME HAS BEEN CHANGED FOR BLACK TO MOVE.
