| brainzugzwang: <PKNJ: 40 ... Qb7 also works, doesn't it?> That's what I thought, too, but looking at the position now, ...Qc6 seems more forcing because of the attack on the White Q. I think ...Qb7 gives White a tempo to play something like 41.h3 and end the back-rank threat. Yes? |

| znprdx: <PKNJ: 40 ... Qb7 also works, doesn't it?> you are probably missing 41.Qc2! |

| zb2cr: <leow>, in your suggested line following 40. ... Qe6, White is up by a Rook and has the luxury of at least 3 winning moves: 44. Re7+ as suggested by <rhedrich>.
44. Rxg6 as suggested by <Gryz>.
Or, simplest of all, 44. d7, Kxe6; 45. d8=Q with a simple win. |

| Jimfromprovidence: There’s a beautiful queen sacrifice that leads to a pawn promotion available to black if white elects to play on after the forced exchange of his queen for a rook. The position after 40… Qc6 41 Qf1 Qc2 42 d7 Rxd7 43 Rxg6+ Kh7 44 Ra6 Rd1 45 Ra7+ Kg6 46 Ra6+ Kg5 47 Ra1 Rxf1+ 48 Rxf1 looks like this...

At least... I played the line of the game exactly. After 40....Qc6 41.Qf1 (Qxc6 Rd1# / Qe2 Qc1+) Qc2 with Rc1. RandomVisitor pointed out that Kg7 is more accurate but is a lot harder to see XD. |

| zanshin: <PKNJ: 40 ... Qb7 also works, doesn't it?> Here's some Fritz 10 analysis (21-ply). 40...Qb7 is good for White because it gives time to move the King safely while allowing an attack on the Black's King. Black needs to keep an eye on his g-pawn as well as against a check on the 7th rank after Re6: 1: Svetozar Gligoric - Fridrik Olafsson, Portoroz izt 1958

2.  (1.92): 40...Kg7 41.Rxg6+
3. (8.92): 40...Qb7 41.h3 Kg7 42.Re6 Rd1+ 43.Kh2 |

| YouRang: <Jimfromprovidence> <The subsequent position is the following...> Er, black would probably want to promote to a BLACK queen. ;-) |

| pshuk: what about 40. Qf7 ? |
|

 |
| kevin86: This one was quite obvious. Black wants to break the pin on his rook so he could deliver a lethal blow on the first rank. So he finds a spot where the queen can make threats of her own. The only hope of a defense is 41  f1 after which black moves the queen down to focus for an attack at d1. There is no escape! |
|

|
| kevin86: <pshuk> 40... f7?? is an egregious error. White would counter with 41 c8+ and the queen will be captured WITH CHECK when the black king movto the second rank.AND,even the rook would fall afterward. |

|

 |
| fm avari viraf: The first thing that came to my mind was 40...Qf7? but White simply wins with 41.Qc8+ & the second was 40...Kg7 then 41.Rxg6+. But finally, I saw White's vulnerable back rank & so 40...Qc6! should win as White will lose his Queen to stave off the mate. |

| znprdx: in retrospect <PKNJ> and <zanshin> isn't it a bit counter-productive to be analyzing the less than best move?, clearly since Qc6 as played is to the point. |

| Jimfromprovidence: <YouRang> <California? Hmmm, for some crazy reason I thought you were from Providence. :-)> I’m bi-coastal. Spent my formative years in New England. Then on to grad school at UC-Santa Barbara. Decided to stay and it's been 20+ years out here. You never can forget your roots, though, especially if you were raised in that part of the country. |

| sandmanbrig: Why can't white play 39 Qxc4+ followed by 40 Qc3 ? Am i missing something? |

| zanshin: <znprdx: in retrospect <PKNJ> and <zanshin> isn't it a bit counter-productive to be analyzing the less than best move?, clearly since Qc6 as played is to the point.> <znprdx> Not necessarily. Sometimes I analyze alternative moves just to see if indeed the best move was played. I often use engine analysis on classic chess games to see if maybe the masters missed anything. Sometimes moves marked !! Fritz assesses as 2nd best (at least at <=20 ply). |

| scolley: 40...Rd1+ cannot be played, the Rook is pinned to the King... |

| whiteshark: Glic missed a lot of good moves from 30 onwards. |

| Breunor: Patzer,
Thanks for the help! It looks like Gligoric self destructed between moves 35 and 40. I guess he was in bad time trouble? Breunor |
