Jan-29-11 | | 1.e4effort: I got the first move 19.Nxf6 but I had Black playing like an idiot in my mind (or maybe more like I would've played) and wrapped him up in 3 more moves. The moves I had are all in the final sequence of moves, of course not in the same order, I just didn't think Black would play his Q after 19.Nxf6. But the game didn't drag on too long, Miles had his man beat no matter what the guy tried. |

Jan-29-11 | | rilkefan: I'm still having trouble with 19...Nh7. I'm not having luck with 20.Ne4 or 20.Qh5 Nxf6. |

 | | scormus: Like others, 19 Nxf6 (if ... gxf6 20 Qh5) was the first move I considered, but in the end I preferred the immediate 19 Qh5. If 19 ... dxc3 20 Qxf6+ Nh7 21 Nxf6 wins. Only problem I had with it was 19 ... Nh7. I seem to be getting better at finding the moves the other kibitzers find, but Im not getting any better at finding the best lines. Time to try it on Rybka? |
|
Jan-29-11 | | smitha1: My thought pattern for today:
"Ah! 19. Nd5... Nah
Yes! 19. Nxf6 gxf6 Hmmm... This is looking good. Now comes 20. Qh5...Wait, why bother playing Nxf6 first? Get the Queen straight to h5. There's no way for Black to regroup... After Qh5, Black must throw in the towel" Fail.
But never to worry, on Monday I will be a grandmaster again. |

Jan-29-11 | | knight knight: <David2009> Actually my second post was after I viewed the game (!), so I missed 19...Qa5, a somewhat alien move taking the queen away from the defense of the 7th (2nd) rank. The game continuation is also a little different from the other lines in that the knight on c3 comes into play. Also, funnily enough I didn't really analyse 19. Nxf6 Nh7, figuring 19. Nxf6 Nh7 20. Nxh7 was not great for black. In this line I guess black must get his material back with 20...dxc3, then maybe white plays 21. Qh5, altho I can't actually see any concrete lines. <Jimfromprovidence> If 19. Nxf6 Rf7 doesn't attack f6 since 20. Qh5 Rxf6 21. Rxg7 is winning, however perhaps there's another reason behind 19...Rf7 that I'm not seeing! |

Jan-29-11 | | lost in space: pppfffff, saw the first move and then got lost (what else can I expect with this name?) |
|
Jan-29-11 | | rilkefan: ... and I can't get 19.Nxf6 Nh7 20 Nh5 to work either, though sometimes it looks close. |
|
Jan-29-11 | | CHESSTTCAMPS: In this middlegame attacking position, white is temporarily down a pawn, but almost all pieces are positioned to strike black's weakened kingside. The doubled rooks on the semi-open g-file are especially imposing, but the Bd3 and Ne4 are strongly mobilized as well. Her majesty can get closer into the heart of the action with gain of tempo, so white should not take the time for the automatic recapture 19.exd4. 19.Qh5!
The offer of the knight on c3 requires more calculation than first appears. Nonetheless, white's overwhelming force must prevail: A) 19... dxc3 20.Qxh6+ gxh6? 21.Rg8+ Kh7 22.Nf6#
A.1) 20...Nh7 21.Qxh7+!! Kxh7 22.Nxf6+ Kh8 (Kh6 Rg6#) 23.Rg5! (Rh3+?? Bxh3) cxb2+ 24.Kb1 g6 (otherwise 25.Rh5+ forces mate) 25.Rxg6 Be6 (to stop mate on g8) 26.Rh6+ Rh7 27.Nxh7 Qg7 28.Rxg7 Kxg7 29.Rxe6 and white is two pieces up. B) 19... Bf5 20.Qxh6+ Nh7 (gxh6 21.Rg8+ Kh7 22.Nxf6#) 21.Qf4 dxc3 22.Qxf5 snatches a piece with continuing attack. B.1) 20... Bh7 21.Nxf6! dxc3 22.Bxh7 cxb2+ 23.Kb1 gxh6 (or gxf6) 24.Rg8+ forces mate. B.1.1) 21... gxh6 22.Rg8+ Bxg8 23.Rxg8#
C) 19... Be6 20.Nxf6! dxc3 21.Qxh6+ gxh6 22.Rg8+ Bxg8 23.Rxg8# C.1) 20... gxf6 21.Qxh6+ Nh7 22.Bxh7 Rxh7 23.Qxf6+ Rg7 24.Rxg7 wins. D) 19... Nh7 20.exd4 and white's multiple threats (including 21.Nxd6 Qxd6 22.Qg6 Nf8 23.Qxh6+) appear impossible to meet. The line 20.Nxf6 Nxf6 21.Rxg7 Nxh5 22.Rxe7 Nf6 comes up short for white, and 20.Rxg7 Rxg7 21.Rxg7 Kxg7 is another I looked at without finding a win for white. Time to view the game and kibitzing to see if D can be improved. Have I missed three in a row? |

Jan-29-11 | | knight knight: <David2009> 19. Nxf6 Nh7 20. Ncd5 cxd5 21. Nxd5 Qd8 22. Nxe7 Qxe7 23. Bxh7 Kxh7 24. Rxg7+ Qxg7 25. Rxg7+ Kxg7 26. Qxd4+ Kf8 27. Qxd5 forking the b7 and d6 pawns, ending up Q + 4P vs R + B + N + exposed king. Presumably not the moves you had but still a winning position I think! :-) |

 click for larger viewAfter 19 Nxf6 Nh7, however, I'm now seeing (with Rybka freeware)that either knight going to d5 wins for white. How about 20...Nfd5?, forking queen and rook?
 click for larger viewNow, if 20...cxd5, then white "reforks" with 21 Nxd5. Black's in a real bind now after 21...Qd8 22 Nxe7.  click for larger viewIt looks like black has to take the knight (because Rxg7 looms), so after 22...Qxe7 23 Bxh7, the bishop looks untouchable because if 23...Kxh7, then 24 Rxg7+, below.  click for larger view |

Jan-29-11 | | CHESSTTCAMPS: <patzer2:> <...I was happy to find my less ambitious solution 19. Qh4! Nh7 20. exd4 is also winning, even though it is not as difficult or strong as Miles move.> If you have a specific line in support of this finding, it would be great if you would share it. |
|
Jan-29-11 | | knight knight: <Jimfromprovidence> I got the same as your second line after following <David2009>'s suggestion 19. Nxf6 Nh7 20. Ncd5, except that I thought there was still a pawn on d5 on move 27 (see post above). I missed 19. Nxf6 Rf7 20. Qh5 Rxf6 21. Rxg7 Bg4! Wow that's some move!! My answer after a bishop move was 22. Rxc7, but that's not working here. So no-one's found an answer to 19. Nxf6 Rf7. Anyone with a decent engine? Where's <wals> when you need him? ;-) |
|
Jan-29-11 | | borginburks: when it comes to a tactic by tony miles you always have to calculate well and it is usually quite difficult and with more than one solution |

Jan-29-11 | | knight knight: Lol "Where's <wals>..."! I'm sure his post is hiding somewhere amongst the kibitzing! ;-) |

Jan-29-11 | | M.Hassan: "Very Difficult" White to play 19.?
White is a pawn down
I saw that White has four pieces aiming at Black King position. Two Rooks in doubled position, a Knight and the Bishop on d3.A knight sac. can bring win:19.Nxf6 gxf6
20.Qh5 Nh7
21.Qxh6 dxc3
22.Bxh7 Qb6
23.Bxc3 Rxh7
24.Qxf6+ Rg7
25.Qxg7#
If the Knight on f6 were not taken by Black, the game could have followed a different line with same results as below: 19.Nxf6 dxc3
20.Qh5 Nh7
21.Qxh6 gxh6
22.Rg8+ Rxg8
23.Rxg8#
time to check
--------------
I am half a mile different from game but with same concepts!! |

Jan-29-11 | | wals: 19.Nxf6 was THE move, for me in fact, the only correct one. Rybka 4 x 64, had this analysis :
d 17 : 15 min :
1. (5.31): 19.Nxf6 Qa5 20.Rg5 Qxg5 21.Rxg5 dxc3 22.Qh5 cxb2+ 23.Kxb2 Be6 24.Qh4 Bf7 25.Ng4 Re6 26.Bf5 Ng6 27.Bxg6 Rxg6 28.Rxg6 Bxg6 29.Nxh6 gxh6 30.Qxh6+ Bh7[] 31.Qxd6 Rg8 32.Qd4+[] Rg7 33.Qxa7 Bg8 34.Qc5 Black's blunder : d 17 : 4 min :
(+5.31):18...exd4. Best,
1. (0.76): 18...Nh7 19.Qh5 f5 20.Qh4 Be6 21.Ng5 Bg8 22.Nxh7 Bxh7 23.Rh3 e4 24.Bc2 a6 25.d5 Rf7 26.Bb3 cxd5 20...Rf7, +19.18, 21...Rxf6, +#22,
and Black resigned at move 23... . |
|
Jan-29-11 | | Marmot PFL: Got as far as 19 Nxf6 and if either knight is taken 20 Qh5, and decided that was enough unless I wanted to spend 30-60 minutes. |

 | | Phony Benoni: <19.Nxf6 Rf7 20.Qh5 Rxf6 21.Rxg7 Bg4>
 click for larger viewIt looks like White may be to settle for the simple 22.R7xg4. Since he is still threatening 23.Rg8#, Black must stop that. White then plays 23.Rxd4, when he's ahead by two pawns and still has a lot of pressure against an exposed king. Not a slam dunk by any means, but probably winning. And Black seems to have nothing better. |
|
Jan-29-11 | | CHESSTTCAMPS: < knight knight: <David2009> 19. Nxf6 Nh7 20. Ncd5 cxd5 21. Nxd5 Qd8 22. Nxe7 Qxe7 23. Bxh7 Kxh7 24. Rxg7+ Qxg7 25. Rxg7+ Kxg7 26. Qxd4+ Kf8 27. Qxd5 forking the b7 and d6 pawns, ending up Q + 4P vs R + B + N + exposed king.
Presumably not the moves you had...>.
That was the very logical and forcing line that I used to beat Crafty EGT (at least thru move 26), having seen David's initial hint. Reminds me of a position from a different POTD a while back. |

Jan-29-11 | | TheBish: Miles vs R Jamieson, 1992 White to play (19.?) "Very Difficult"
I think I found the key move right away, just a matter of analysis now. 19. Nxf6!
This opens up the bishop, which is needed for the attack. The queen will join in on h5 (the rook battery is perfectly placed). The Nc3 is expendable. Also, the knight on f6 cannot be safely captured, making it a dangerous attacking piece. Now: A) 19...gxf6? 20. Qh5 Nh7 (20...dxc3 21. Rg8#) 21. Qxh6 and the threat of 22. Rg7 will decide quickly. B) 19...Be6 20. exd4!
Now is the time to save the other knight!
20...gxf6
Or 20...Rf7 21. Nh5, and White's attack rages on, a pawn up. 21. Qh5 Rh7 (best try) 22. Qh4! Ng8 23. Bxh7 Nxh7
Definitely not 23...Qxh7 24. Rxg8+ Bxg8 25. Qxf6+ and mate next. 24. d5! cxd5 25. cxd5 Bxd5
Taking advantage of the pin on the c-file, but that will soon be gone! Also, 25...Bf7 26. Rg7 is curtains. 26. Rg7 Qxg7 (forced) 27. Rxg7 Kxg7 28. Nxd5, and White has a winning advantage of queen vs. rook and bishop. Time to see what I missed! |
|
Jan-29-11 | | TheBish: Ok, I missed the reply 19...Qa5, but I don't think 20. Ncd5! would be too hard to find, considering the knight was attacked anyway, and it totally fits in with the idea of getting White's queen to h5. |
|
Jan-29-11 | | TheBish: Miles missed the even stronger 23. Qh4! but if your opponent resigns, I guess the move was good enough. After 23. Qh4, Black could have tried 23...Ng4!, hoping for 24. Rxg4? Qe1+ 25. Kc2 Rxf2+ 26. Kb3 Qd1+ 27. Ka3 Qxd3+ 28. b3? Rxa2+!! 29. Kxa2 Qd2+, drawing, but even in this line White has 28. Nc3! Rh7 29. Rxh7+! Qxh7 30. Rh4 with advantage. |

This is one of those games when I would like to take it aprt with the computer. (Too tired.) |
