| Mar-11-12 | | Elo: Was 17.a3 necessary first? |
 |
| Mar-11-12 | | dragon player: White has more space and black's king is under pressure.
I think I have to make some sacs on g6 or f7. I've been
looking for a while, but I see nothing at all. I'll just
check the solution, I probably won't solve it.
-------------------
Sacs were indeed made on g6, but I would never have
spotted Qb1.
6/7 this week. not bad. |

 | | Patriot: I missed it. I should have seen 21.Qb1 at least, but 20.Qb1 is even better! |
|
| Mar-11-12 | | viking78: very nice and instructive, saw attack on g6, but i played 20.Rxg6+ and 20....Kh7 left me with no more ideas. |

 | | David2009: Nowhere near solving this. I'm glad Miles captured the B - otherwise I would never have dreamed of the follow-up. http://www.chessvideos.tv/endgame-t... is an interactive link to today's POTD puzzle Keene vs Miles, 1975 White 18? Insane

 | | scormus: <Sevenseaman> Well done, 20 Qb1! was the key find. I think the lines you want are by Robert Frost
"...
I have promises to keep
And <miles to go> before I sleep
..." |
|
| Mar-11-12 | | SpoiltVictorianChild: Wow, Qb1 is incredible. That's the mark of genius that my play will never have... |
|
| Mar-11-12 | | LoveThatJoker: Awesome! A GM Keene puzzle.
<18. Nxg6 hxg6>
(18...Bd6?? 19. Ne7+ Kh8 20. Bg7#; 18...fxg6?! is not as strong for Black as it takes away the option of playing ...f5 in certain lines) <19. Bxg6 Bd6>
[19...fxg6 20. Qb1! and now the only way that Black can protect g6 is by returning both pieces and hence saddling his game with a significant material and positional defecit; for example, 20...Ne5 21. dxe5 Ne4 22. Nxe4  ] <20. Bxf7+ Kxf7>
[20...Kh8 21. Bg7+ Kh7 22. Qb1+ mates; 20...Kh7 21. Qb1+ Ne4 22. Qxe4+ Kxh6 (22...Kh8 23. Bg7#) 23. Qg6#] <21. Rg7+ Kf8 22. Rxb7+>
(This looks better to me than 22. Rd7+)
<22...Kg8 23. Qd3 Ne7>
(23...Ne5 24. dxe5)
<24. Qe3 Kh7>
(24...else and White is winning due to the double attack on g5 and e6; 24...Bxh2+ 25. Kh1 and once again White has a winning game) <25. Qg5>
(but not 25.Qxe6? in this case as 25...Rc6 defends admirably for Black) <25...Rg8 26. Qh4!> and White has an extremely strong attack on both Black's K and the N on f6 (Note that if it were White's move in this position he could regain his material with interest at once via Bg5+) LTJ |

 | | WinKing: Very nice puzzle today. I remember this game fairly well as <kingscrusher> did a video on this game that is quite instructive. Keene's 20.Qb1! is a beautiful move! http://www.youtube.com/watch?v=YwXu... |
|
| Mar-11-12 | | LoveThatJoker: Firstly I want to start off by saying that I'm glad I got the puzzle right today, for the full point, and that I finished the week with 6.20/7 for a pass.
I'm on 3 consecutive streak and I certainly hope I can build on that. :D Secondly, now that I can shuffle the pieces I want to make a correction on my 18. Nxg6 hxg6 19. Bxg6 Bd6 20. Bxf7+ Kxf7 21. Rg7+ Kf8 22. Rxb7+ Kg8 23. Qd3 Ne7 24. Qe3 Kh7 <25. Qxe6> line: It is actually very good for White as 25...Rc6 allows both 26. Bf4 and 26. Qf7+ when White has the better game. Position after 24...Kh7
click for larger viewFurthermore, after 18. Nxg6 hxg6 19. Bxg6 Bd6 20. Bxf7+ Kxf7 21. Rg7+ Kf8 22. Rxb7+ Kg8 23. Qd3 Ne7 24. Qe3 Kh7 25. Qg5 Rg8 <26. Qxf6> is a lot clearer and most likely better than 26. Qh4. Position after 25...Rg8

| Mar-11-12 | | Jim Bartle: I got today's puzzle, but only because I'd read the notes as I went through the game and they said "the granite wall on g6 already had faulty foundations." So I looked at that first. Plus I played a game against a computer recently with five pieces aimed at an equally protected pawn on g6, so it was almost a repeat. |
|
Mar-11-12
 | | hedgeh0g: <Elo> I think 17.a3 was necessary to eliminate interference defences involving ...Ne4, i.e. 17.Nxg6?! hxg6 18.Bxg6 fxg6 19.Qb1 Ne4! 20.Nxe4 Qxd4! and if 21.Nd6, maybe 21...Rc8+!? is a possibility, although White probably stands much better. |

 | | ray keene: thanks for all the nice comments-btw on www.braintrust.org.uk i have an interview up with andrew paulson who has taken over the world chess cycle from fide. |
|
Mar-11-12
| | Patriot: <ray keene> That was a brilliant combination, especially to play it OTB! |
|
| Mar-11-12 | | gofer: Well I think the point of attack is pretty obvious; Pg6. Also, the first
piece to attack it being Ne5 is also quite clear. But then we have a
number of choices, but after while it is clear that I would like to
take with either Bb1 or Rg3 and then follow up with my queen, but the
entry squares for the queen are few and far between. In face at the moment
there are none. So then it is clear that the second piece to take Pg6 is
Bb1, which leaves the queen an entry square!
<18 Nxg6 fxg6/hxg6>
<19 Bxg6 ...>
19 ... hxg6/fxg6
20 Qb1 ...
White has played a big fat <GOOT>. White has given up two minor pieces
for two pawns and a HUGE attack. So how can black defend this? I can't
see a way for black to defend this! So we have to back up a move as
black cannot accept the bishop sacrifice!
NOW, we have an insane puzzle! So many options after 19 ... Bd6 or 19 ... Bf8.
Its late and I am too tired to work any harder...
Time to check...
~~~
Wow, black took played the continuation I thought he couldn't... |
|
| Mar-11-12 | | LoveThatJoker: <ray keene> I read the interview. He sounds like a well-grounded person. So long as the money is there, I have a great feeling about Mr. Paulson's relationship with Chess. I truly wish that everything goes swimmingly for the World Championship Cycle from now on. Best of luck to FIDE and Mr. Paulson to bring Chess into the mainstream! LTJ |
|
| Mar-11-12 | | SimonWebbsTiger: @<Ray>
I can imagine Tony completely missed Qb1; it is one of those "long moves", with the twist the queen used her rook attributes ("oh Matron"!) to get there first. Did you discuss the game afterwards? @<LoveThatJoker>, the cynical and jaded here will believe it when we see it actually happening. I simply don't trust FIDE, with its friend of dictators (eg the late Ghadaffi) and ET president.... |
|
| Mar-11-12 | | LoveThatJoker: <SimonWebbsTiger> Your comment is well-founded, man. I'm also of the mindset that us, the chess public, need to see the good things happen first. But am just saying that I'm hoping it does happen.
That being said, again, what you said is well-founded. Here's hoping to a better time, man!

 | | sevenseaman: <Black has a plan here as well. He wants to play 18...Nxe5, seeing 19 dxe5 Rxc3!, exploiting white's vulnerable back rank. <He's just beaten to the punch.>> <jimfromprovidence> A very insightful and alert observation. I think Miles missed it by mere millimetres. Its just the accident of his name that prompted one of the finest puns I've seen on <CG>. Thanks <scormus>. "The night is long and the forest deep ........and miles to go before I sleep" - Robert Frost, were the favorite (often quoted) lines of <Pandit Jawahar Lal Nehru>, India's first prime Minister. |
|
| Mar-11-12 | | stst: looks simple, if Black "cooperates":
18.Nxg6 hxg6
19.Bxg6 fxg6
20.Rxg6 Kf7
21.Qd3 Qxd4 (tries to exchange out Q)
22.Rg7+ Kf8
23.Rg4 dis+ Kf7
24.Qg6# |
|
| Mar-11-12 | | stst: I go against all praises,
20.Qb1 is "soft" and delays the win somewhat.... |

| | sevenseaman: <stst> <I go against all praises,
20.Qb1 is "soft" and delays the win somewhat....> I like your spirit of adventure but you must consider 21...Ne5, forking the White R and the Q. I think its better for Black than <21...Qxd4> you have chosen. |
|
Mar-11-12
 | | James D Flynn: My main line goes
18.Nxg6 hxg6 19.Bxg6 fg6 20.Qb1(and Black must interpose or divert the Q) Ne5 (the only defense to g6) 21.dxe5 Ne4 22.Nxe4 Rc1+ 23.Qxc1 Bxe4 24.Qf4 Bf5 White is the exchange and 2 pawns up and can force the exchange of the black square bishops by Bg5, Black should ,perhaps, resign. However White can play to win the B on f5 e.g 25.Rc3 Qd5(gives up the reply g5 to the threatened g4 but Black is in virtual Zugzwang ) 26.g4 Be4 27.f3 Qd4+ Kh1 and White is a rook up.
Black has to take the N on move 18 because of the double check Ne7 eg. 18. Nxg6 Bd6 19.Ne7+ Kh8 Bg7#. Black can certainly try something other than taking the B on move e.g 19. …. Bd6
18.Nxg6 hxg 19.Bxg6 Bd6 20 Bxf7+(Black cannot decline this one Kh8 21 Bg7+ Kh7 22.Qd3+ and mates on g6) Kxf7 21.Rg7+ Kf8(obviously White has perpetual here is he wants it with Rg3)22.Rd7+ Kg8 23.Rxd8 Rfxd8(Black has a material advantage with R , B, nad N for the Q but his K istill under attack) 24 Qf3 Kf7 25.Ne4 Be7 26 Nxf6 Bxf6 27<bxg5 wins the B on f6 and with Q for R and N plus 3 pawns and the exposed Black K White has a clear win. If instead 24….Rf8 25.Bxf8 Rxf8 26.Rd1 and White has more than enough material for the 3 minor pieces.
Now for the game. |

| Mar-11-12 | | TheBish: Keene vs Miles, 1975 White to play (18.?) "Insane"
Funny, but when I first typed the above, it read "Inane", so I had to fix the typo! Back to the problem... I sense a sacrifice coming! 18. Nxg6!! hxg6
I don't think there is much difference between this and 18...fxg6, as the follow-up move will be the same in both cases; the bottom line is White is weakening the king's position. Note that 18. Bxg6 first allows 18...Nxe5, which should still win after 19. Be4+ Ng6 20. Bxb7, but White wants to attack the king. 19. Bxg6 fxg6
Maybe not the best, but the threat was 20. Bd3+ Kh8 21. Bg7+ Kg8 22. Bxf6+. 20. Qd3 and the threat of 21. Qxg6+ with a quick mate will win, e.g. 20...Bf8 21. Qxg6+ Kh8 22. Bg7+ Kg8 23. Bxf6+ will mate. ~~~~~~~~~~
Nuts! I rushed the ending. Close but no cigar. Analyzing from the position, the defense (after 20. Qd3) ...Ne5! is easy to miss, but I'm sure in a game situation I would have seen that coming. |
