 | | OhioChessFan: He staggers to the end of life's stage, the weight of The World's need for soul on his bowed shoulders. The World roars for one last encore, one more chance to scream in delight at the epitome of human passion. He sweats, he shrugs his shoulders, his handlers rush to grab his cape. OwwwwwwwwwWWWWWWWWWWwwwwwwwww, who wouldn't kill to be the person that grabbed that cape just one time! The World screams, "Come back, we need you JAMES!" But unlike every other performance, this one ends. His fans are stunned. They need the cape. They need the encore. They need the soul. But the Godfather of Soul has left the stage, and there are no more encores. We feel bad. We don't got you. |

| Dec-28-06 | | myschkin: <SantaChessFan> congrats for giving poor people the chance to participate on a par with others. Give a hug to your anonymous "soulmate" (? in German it makes sense, hope it fits in here) aswell ;)
See you in 2007 and take care.
Well done! |

| Dec-29-06 | | twinlark: <Ohio> <FWIW, I think Qa7+ isn't a good idea. I sort of sense most the best analysts agree, although they've been mostly quiet the last few days. > I agree, I think this variation is basically played out enough to abandon it in favour of 39.b5. It's a tantalising line, as whenever you think you're getting close, the definite win remains just beyond one's grasp. No such uncertainty with Rook Variation Numero Uno. |
|
| Dec-31-06 | | twinlark: Greetings from 2007, <Ohio> old mate. May yours be bigger and better than 2006. |
|
| Dec-31-06 | | twinlark: Maybe the <37...Qe8 38.Qb6 Qc8 39.Qa7+ Kh6 40.Qf7> variation is not yet fully played out. <Boomie> and <dalbertz> (the latter on Eyal>'s forum) have some lines involving 42.Qxd5 that very likely prevail. The question is whether they do as well as Rook Ending Number One. The variations with 42.Qxa6 are not worth pursuing. |
|
| Dec-31-06 | | twinlark: <Boomie> I've been running the line you posted in your last post, and there's no obvious win, notwithstanding that the calculator rates it at nearly +4. The pawn gets to a7, but there doesn't seem to be an obvious and quick way of queening the little beastie without allowing a perpetual. The Queen ending may be won, but it looks like a long and tedious one. I think a better line would be to retain the Rooks after 42...Rf6 with 43.Rb3 |
|
| Dec-31-06 | | twinlark: <Tabanus>
I've spent the last few hours condensing the analyses and discussions from <Eyal>'s forum that you referred to in your slightly angry post on the main thread. Copying all the posts would have been too confusing, so I've attempted to distill the analyses of <Dalbertz>, his discussions with <RookFile> and a few other contributions by others (eg: from <Boomie>) along the way, shorn of dead ends, typos etc. Hopefully, the following faithfully represents the analyses you thought should be included on this forum: 37. Qd8 Qe8 38. Qb6 Qc8 39. Qa7+ Kh6 40. Qf7 Qe8 41.Qb7: <A>. 41...Re3 42.Rf1 Re2 43.Qxa6 Qe4 44.Rg1 Rb2 45.Qxd6 Qxd4 46.Qf8+ Kg5 47.a6 Ra2 48.Qe7+ Kh6 49.Rf1 (49.b5 also wins, because black doesn't have a perpetual by Rxg2+ any more (the queen on e7 defends from further checks)) The continuation might be:
49...Rxa6 50.Rf7 Qh8 51. b5 Qb8+ 52. g3 Ra2+ (looks like draw at first, but isn't) 53. Kh1 Ra1+ 54. Kg2 and then:
1. (9.53): 54...Rg1+ 55.Kxg1 Qxg3+ 56.Kf1 Qxh3+ 57.Kf2 Qh2+ 58.Ke3 Qg1+ 59.Kd3 Qb1+ 60.Kd4 Qb2+ 61.Kc5 Qa3+ 62.Kxd5 Qd3+ 2. (11.69): 54...Ra2+ 55.Kf3 Qg8 56.Qe3+ g5 57.Rf6+ Qg6 58.Rxg6+ Kxg6 59.Qe6+ Kh7 3. (16.32): 54...Qg8 55.Qe3+ g5 56.Rf6+ Qg6 57.Rxg6+ Kxg6 58.Qe6+ Kg7 59.Qe5+ Kg6 60.Qxa1 g4 61.Qd4 gxh3+ 62.Kxh3 Kf7 4. (#4): 54...Qxg3+ 55.Kxg3 Rg1+ 56.Kh2 Rh1+ 57.Kxh1 g5 58.Qf6# <B>. 41...Qh8 42.Qxd5 Rf6 43.h4 Rxf3 44.gxf3 Qe8 45.Qe4 Qb8 46.d5 Qc7 47.Qd4 Kh7 48.b5: <B1> 48...axb5 49.a6 <B2> 48...Qxa5 49. Qa7+ Kh6 50. bxa6 Qd2+ 51. Kh3 Qe2 52. Kg3 Qe5+ 53. Kf2 Qh2+ 54. Kf1 Qh1+ 55. Ke2 Qxh4 56. Qe3+ Kh7 57. a7 ******
I'd make the comment that Black's chances probably lie with variation <B>, as I'm not sure the win has been fully demonstrated in these lines. |

 | | Tabanus: <twinlark> Hic, excellent! Sorry for the inconvenience. I was not thinking of you or any other person, just a feeling that something unnecessary had happened on the main page. I'll post some additional stuff here tomorrow. G'night ¤¤ |
|
| Dec-31-06 | | twinlark: No worries, Tab, it was simply an oversight on everyone's part, noting more. I had to redeem my feelings of some minor guilt, not so much for missing this analysis, as for dismissing the entire 40.Qf7 line on the basis of exhausting the 42.Qxa6 Qh8 variations. If the Qxa6 variations get somewhere, they do so a lot slower than Rook Variation Number One. G'night. |

| | Tabanus: <twinlark> I long thought 41...Qh8 was best, but 42.Qxd5 Rf6 43.b5! Rybka 2.2 analysis of 38...Qc8 39.Qa7+ Kh6 <40.Qf7> Qe8 41.Qb7 Re3 42.Rf1 Qe4 43.Qxa6 Re2 44.Rg1 Qf4+ (else Qxd6) 45.Kh1 (24-ply): (2.45) 45...Rb2 46.Qa8 Kg7 47.Qb8 Rb3 48.Qc7+ Qf7 49.Qxd6 (3.10) 45...Rc2 46.Qd3 Rd2 47.Qc3 g5 48.b5
There is no point in 42...Re2 43.Qxa6 Qe4, which just transposes. <dalbertz> and <Boomie> have taken this line further (to a win). Previously we have seen 25-ply (2.50) 42...Rb3 43.Qc7 h4 44.Rf7 Re3. Another try is 42...Qb5 43.Qf7 Qe8 (forced) 44.Qf4+ Kg7 (Kh7 is worse) 45.Qxd6 Re6 (Re7 does not help) 46.Qxd5 (24-ply): (2.08) 46...Qb8+ 47.Kg1 Re7; (2.17) 46...h4; (2.20) 46...Kh6 where black is two pawns down without counterplay.
Finally 41...Qh8 42.Qxd5 Rf6 43.b5 (24-ply):
(3.97) 43...Rxf3 44.Qxf3 Qxd4 45.Qf8+ Kh7 46.Qf7+ Kh8 47.bxa6 so black could try 42...Qc8 43.Rf7 (23-ply):
(2.80) 43...h4 44.Rf4 Kg7 45.b5 axb5 46.a6 Re7
or 42...Qe8 43.b5 axb5 44.a6 Re7 45.Rf6 (23-ply):
(2.82) 45...Qb8 46.h4 Rg7 47.g4 hxg4 48.Qg5+ Kh7 49.h5 Black improvements? I could not find any. Black's best line seems to be the top line in <RV>'s Section C1: [38...Qc8 39.Qa7+ Kh6] 29-ply (1.97) 40.Qf7 Qe8 41.Qb7 Re3 42.Rf1 Qb5 43.Qf7 Qe8 44.Qf4+ |

Rather scary, I must admit. Black does run out of checks, no? On the other hand, 40.Rf7 avoids all this. |
