| Sep-18-11 | | SimonWebbsTiger: I'll add a few more details to this game via my ever trusty Informator collection. This game (ref 37/412) was awarded third best game prize with 49 out of 90 by the panel of Inf. 38. Lev must have enjoyed the sacs because he gave himself 8/10 points! In his notes, instead of 21...g6, he gave the line <21...Bf8 22. Bg5! Be7 23. Bh6 Bf8 24. Rg7 Bg7 25. Qg4 Kf8 26. Qg7 Ke7 30. Bg5  > It was at the same tourney, <the Phillips and Drew> won by Karpov with 9/13, that the joint first best game of Inf 38 (the other was Portisch-Pinter) was played, between Karpov and Korchnoi. British <Chess> magazine (June 1984) gave its front page to Korchnoi shaking Karpov's hand. Viktor the Terrible was slightly late and apologised in Russian, which brought prolonged applause from the audience. This was their first meeting in a non-FIDE event since the USSR chp, 1973 and a sensation after Baguio, etc. |

 | | sevenseaman: <BOSTER> Smart thinking, a very clever intermezzo at 22. Bg5 (22. Bc5 confused me; I am sure its a typo). This tempo gaining idea is not so easy to occur. |
|
| Sep-18-11 | | BiteByBits: ok really, with a seemingly closed position the only insane thing you could do is Bxh7+
19.Bxh7+
-19...Kxh7 20.Qh5+ Kg8 (forced)
21.Rg3! 21. g6 (or 21...Bh6!) 22.Rxg6+ fxg6 23.Qxg6+ Kh8 24.Qh6+ Kg8 25.Qxe6+ Kh8, 26. Qh6+ Kg8 27.Qg6+ Kh8 28.Qh5+ Kg8 29.Bh6 (this is the key move that i missed) Bf8wow i learned something new today... |

 | | Memethecat: <sevenseaman> spot on, flawless except for a small typo move 30, but i think thats forgivable, just. so i guess what your getting at is "once upon a time" you were in my shoes thinking its impossible to think in that kind of depth, but with time and work you can. I wonder if there is an exercise to help improve, like doing scales on an instrument, maybe not, thats muscle memory. thanks for your input, i'll just keep trying to exercise my cognitive muscles & hopefully it'll start to show. |
|
| Sep-18-11 | | Old King Cole: A precise series of "only"-type moves wends it way to a sound K-side checkmate with flashy bishop and rook sacrifices. Qh5 is an elusive move which evades us, and which avoids losing, keeping the combo alive. |

 | | David2009: <scormus: <the last few kibitz's> Thanks for the discussion, I always look out for Jim's avatar because when I see it I know there will be something worth look at.> I very much agree with this last sentiment. I also welcome sight of <Patriot> and <abuzic>'s contributions. <abuzic> gives the key to beating Crafty End Game Trainer (link in my earlier post Polugaevsky vs E Torre, 1984). Playing through his suggested attacking line, the EGT defends against
19.Bxh7+ with 19...Kxh7 20.Qh5+ Kg8 21.Rg3 Bf8 22.Bh6 Re7 23.Bxg7 Bxg7 24.Raa3 Qf8 25.Raf3 f6 26.exf6 Nd7 27.Rxg7+ Rxg7 28.fxg7 Qxg7 29.Rg3 Qxg3 30.fxg3 Nf8
to reach 
click for larger view which turns out to be a straightforward win against Crafty EGT starting Kh2 (to avoid nuisance or tempo-gaining checks down the c-file which
White cannot readily prevent Black from occupying).
<Jim> commenting on 25 Raf3! in this variation <The threat is 26 Rf6, then Rh6.> Thank you! <Black cannot stop it without giving up major material.> Exactly. The EGT gets away with keeping RN vs Q but the three passed King side Pawns decide. Interesting that <patzer2> had given almost all this way back in 2004! (see page 3 of kibitzes). Finally, in the 19...Kxh7 20.Qh5+ Kg8 21.Rg3 Bf8 line, <Patriot> and <SimonWebbsTiger> suggest 22.Bg5. Crafty EGT meets 22.Bg5 with 22...Qa5! and if 23.Bf6 Qd2 24.Raa3 Qxb2 25.Rxg7+ (if 25.Kh2 Qxa3! 26.Rxa3 Bxa3!) 25...Bxg7 26.Rg3 Qb1+ 27.Kh2 Qh7 and Black seems to be surviving. If 23.Bh6 to prevent Qd2, Black has 23...Qb4! hitting b2 with similar variations. |

| | sevenseaman: Thanks <SimonWebbsTiger> for the Polugaevsky notes. <21...Bf8 22. Bg5! Be7 23. Bh6 Bf8 24. Rg7 Bg7 25. Qg4 Kf8 26. Qg7 Ke7 30. Bg5 > is an improved line. <22. Bg5> is a brilliant idea that I came across today in a <BOSTER> discussion. It struck me as a very clever intermezzo. With so many sharp witted contributors this site is becoming more and more interesting and enjoyable. |

 | | Domdaniel: I've seen this game before - though I thought it was won by Korchnoi, so memory isn't helping today. It's clear that White's first three moves are Bxh7+, Qh5+ and Rg3, with Rxg6 to follow. The *last* move will be Raa3, once the pesky Bishop has been eliminated. So a sequence of checks is needed, though I don't think it's necessary to take on e6. I hope people had more fun with this one than Sundays usually provide. |

Thank you for choosing my comment among so many <brilliants>. |

| Sep-18-11 | | abuzic: <The 22.Bg5 variation> After 19...Kxh7 20.Qh5+ Kg8 21.Rg3 Bf8 22.Bg5 if 22...Qa5 then white continues not <23.Bf6> but 23.Rg4 first with the threat of Rh4 such as: 23...Nd7 24.Rh4 f6 25.exf6 Nxf6 26.Bxf6 Qd2 27.Bg5 Qd3 28.Qh8+ Kf7 29.Rf4+ Kg6 30.g4 Kxg5 31.Qh5+ Kxf4 32.Qe5+ Kf3 33.Re1 mating soon. Black could of course give the Q with 27...Qxg5 28.Qxg5 or with 29...Qf5 30.Rxf5 exf5 31.Qh7 and white wins in both case. Black must defend with 23...g6 and now 24.Bf6 Bg7 (otherwise cannot avoid mate) 25.Rxg6 fxg6 26.Qxg6 Re7 27.Bxe7 followed by Qxe6.
So for 22.Bg5 black defends with either 22...Re7, or 22...Qa5 thus making 22.Bh6 the best continuation which deserves at least !. |

 | | agb2002: White has the bishop pair for a bishop and a knight. Black would probably consider ... Nd7 and ... Nf8.
The first idea that comes to mind tries to exploit the weakness of the squares f7 and h7 with 19.Bh6 gxh6 20.Bxh7+ Kxh7 21.Qxf7+ Kh8 22.Rg3 Rg8 23.Rxg8+ Qxg8 24.Qxe7 Nc6 but this is unclear. Another option is to weaken the black castle with 19.Bxh7+ Kxh7 (otherwise there is no compensation for the pawn and the new weaknesses in the black castle) 20.Qh5+ Kg8 21.Rg3 A) 21... g6 22.Rxg6+ fxg6 (22...

I think I'd play 19.Bxh7+. |

| | sevenseaman: Thanks <al wazir> You have a happy flair for digging out the right reference. I just read it on my 'graffiti' box in my daily newspaper, 'The Times of India', little knowing great men have said it before. It struck me as 'brilliant' and quoted without any apprehension of plagiarism. |

 | | M.Hassan: "Insane" White to play 19.?
Sides are equal.
Taking h7 pawn matches with insane category and it is not difficult to see:19.Bxh7+ Kxh7
20.Qh5+ Kg8
21.Rg3 Bh4
22.Rg4 Nc6
23.Rxh4 Qxh4
24.Qxh4 Nxd4
White hhas more materials and will obviously win.
The game may have followed a different course on move 21. To follow accurately, moves from 19 are re-written: 19.Bxh7 Kxh7
20.Qh5+ Kg8
21.Rg3 g6
22.Rxg6+ fxg6
23.Qxg6+ Kh8 (the only safe square for now)
24.Qh6+ Kg8
25.Qxe6+ Kh7
26.Qh6+ Kg8
27.Qg6+ Kh8
28.Qh5+ Kh7
29.Bh6+ Kh7
White has exerted extensive pressure on Black King but it appears that Queen and Bishop in this combination are not sufficient force to mate and I don't know what happens next. Will check the game
------------------
Right. White had to bring a Rook into play to get results |

| | al wazir: <Shams: Have you read Boswell's biography?> Yes. I didn't enjoy it as much as I thought I would. (Probably because a friend had overpraised it.) To paraphrase the good doctor, it's worth borrowing from your local library but not worth keeping. <I've been thinking lately I should read it. Or a suitably slimmed down version of it.> What, the Classics Illustrated version? |
|
| Sep-19-11 | | SimonWebbsTiger: eeeeeew, how cultural: chess players reading Boswell's biography of Johnson! Personally, I prefer the dictionary episode of Blackadder III myself. ;o) |
|
Sep-19-11
| | Shams: <aw> I love illustrations. Heck, this is one of my favorite books of history:
http://amzn.to/pJ0glP
But as for Johnson, I think somewhere between volumes I and XVIII I might reach my fill. |

| | sevenseaman: <Memethecat> Hard work is the only key. If it is driven by interest and enjoyment, it will scarcely seem hard. Time will ring in an amazing improvement. In the beginning one needs to attend to the simpler ones and not meet frustration half-way by trying the harder POTDs. Another golden rule is to read very carefully the solutions posted by those who go into meticulous detail.
You'll soon have a preferred list. |

 | | whiteshark: You need 2.5 lives to do an accurate post-mortem analysis on <21...Bf8>. Well, maybe a week should also do it. :D |
|
| Nov-17-11 | | Nemesistic: A stunning Rook and Knight sac,but once White plays Raa3 surely Black can wriggle out of this albeit losing his Queen,but he's alresdy well up in material..However i dont have the benefit of an engine to Analyse right now,so if not that's Brilliant play by White and to see from move 19 through to where he did is Astounding! Brilliant Game |
