 | | offramp: No. Friday puzzle after 26...Qg5. |
|
| Dec-20-13 | | BxChess: If instead of 30 ...Nd7, which leads to the neat Q sacrifice by White followed by mate in 3, Black tries 30...Kf6,
then 31 Rf1+ Kg6, 32 Qxf7+ Kh6, 33 Nf5+ Qxf5, 34 Rxf5 g6 35 Bc1+ g5 36 Nxg5# |
|
| Dec-20-13 | | Cheapo by the Dozen: If Black interposes at e7, the win is
28 Ne6+ Nxe6
20 Bxd6+
At the moment I'm still missing a couple of other lines. |
|
Dec-20-13
 | | LIFE Master AJ: 27.Rf7+! followed by 28.Qc6+ looks to be the start of an extremely strong attack. (I only used about 5-7 minutes, and did not finish my analysis - some of the lines branch, and I am getting tired.) |
|
Dec-20-13
 | | al wazir: I missed it. But I think my 27. Bxc5 also wins: 27...dxc5 (27...bxc5 28. Rb7+ Kd8 29. Rb8+ and mate next) 28. Ndb5+ (28. Nc6+ Rxc6 29. Qxc6, my original idea, doesn't work) axb5 29. Nb5+ Kb8 30. Rxf8 Rhxf8 31. Qd6+ Ka8 32. Nc7+, etc. |

| Dec-20-13 | | marcwordsmith: what if black refuses the rook sac? What if plays, for example, Re7 instead of Nxf7? |
|
| Dec-20-13 | | WoodPushkin: Greetings
While 27. Rf7+ initiates the queen invasion I only saw till 30... Kf6 31.Rf1+ Kg6 32. QxNf7+....which is not so hard to get to but it is only up a piece and in my head didn't scream obvious checkmate. I would have entered this sac like 1960'sTal, pretty sure it works but can't see it to conclusion. JAH love |

|
| Dec-20-13 | | zb2cr: Totally missed this one. I spent a lot of time analyzing 27. Bxc5, then saw the 27. ... Nf3+ defense and was flummoxed. |
|
| Dec-20-13 | | abuzic: After 27.Rf7+, black has 8 possible responses:

| Dec-20-13 | | morfishine: Something dramatic must happen because Black threatens 27...Nf3+ winning the White Queen <27.Rf7+> 27...Nxf7 28.Qc6+ (I only found this once I realized 28.Qxf7+? is thwarted by 28...Re7) 28...Kd8 29.Qc8+ Ke7 30.Nac6+ Kf6 31.Rf1+ Kg6 32.Qxe8 I figured White was winning here, but it turns out it wasn't so easy

PM1: A marvelous finish by White! I wouldn't have seen that in a million years. With the aid of a PGN viewer, I checked to see if my continuation holds up If now 32...Qd5 33.Bxc5 bxc5 (33...dxc5? is a mistake since Black must maintain control over e5: 33...dxc5 34.Rxf7 Qxf7 35.Qxe4+ Kh5 [35...Kf6 36.Qf5# or 35...Kh6 36.Qh4+ Kg6 37.Ne5#] 36.g4+ Kg5 37.Nf3+ Kh6 38.g5+ Kh5 39.Nce5) 34.Rxf7 Qxf7 35.Qxe4+ Kh5 36.g4+ Kg5 37.Nf3+ Kh6 38.Nd8 Qe7 39.g5+ Kh5 40.Ne6 h6 41.Nf4+ Kg4 42.h3+ Kg3 43.Ne2+ Kxh3 44.Qh4#

| Dec-20-13 | | gofer: The combination is a sweet one. A case of putting black in
a position where each decision leads done a more difficult
decision... ...and each path leads to his doom!

Poor old black, a few moves earlier he was hoping to be able to
play Nf3+ winning white's queen, now he is putting on hit coat... ~~~
Yep! But a slight variation. I did see the rook and 2 knights mate,
but didn't think black would go there I thought the king would just
leg it... |
|
| Dec-20-13 | | mel gibson: Black lost the game with 23.... Qxf4.
It gave an open powerful f file, which white attacked with it's Rook,
giving a handy check for white.
The correct move was 23.....b6.
24. f5 Rg8 etc.
It then leads to a draw according to my computer. |
|
| Dec-20-13 | | diagonalley: well ... after much gazing, 27. R-B7+ did look the most likely candidate - but it was not at all easy to calculate all of the possible continuations... can somebody with a machine come up with any viable defence for black(?)... |
|
| Dec-20-13 | | Stormbringer: Huh. I wanted to do Rf5, threatening the queen and directly attacking the knight that needs to be moved away. |
|
Dec-20-13
 | | Penguincw: Oops! Wrong rook sacrifice (27.Rxb6). |
|
| Dec-20-13 | | Nick46: Neat finish. Rev. Palmer got run over by the Carr. (Reminiscent of the "Fish called Wanda" steamroller scene.) |
|
Dec-20-13
 | | kevin86: My move was Rf5 chasing the queen-the sacrificing the rook for the knight. The actual move was far more vigiorous. |
|
| Dec-20-13 | | Patriot: I had several main candidates and finally saw a flaw in both! 27.Rxb6 and 27.Bxc5 can both be defeated with 27...Nf3+ followed by 28...Qxd5. I didn't notice the x-ray of both queens, which kind of concerns me because this is something I've focused on in the past. 27.Rf7+ is more forcing than both and I think I see a reason for tossing the rook. 27.Rf7+

27...Qe7 just loses. |
|
| Dec-20-13 | | Patriot: I couldn't visualize the vacant f6 square in the first line for some reason. |
|
| Dec-20-13 | | Patriot: <morf> - Good job! I failed to see the 27...Nf3+ threat from the get-go. |

 | | agb2002: White is three pawns down.
Black threatens 27... Nf3+ winning the queen and 27... Qe3+ winning the bishop. The position of the black king and white pieces suggests 27.Rf7+: A) 27... Kb8 28.Rxb6+ Nb7 29.Qxb7#.
B) 27... Kd8 28.Qa8#.
C) 27... Nxf7 28.Qc6+
C.1) 28... Kb8 29.Qxb6+ Ka8 30.Qc6+ Kxa7 31.Bxc5+ dxc5 32.Qb7#. C.2) 28... Kd8 29.Qc8+ Ke7 30.Nac6+ Kf6 31.Rf1+ Kg6 32.Qxe8 Qe3+ 33.Kh1 Qxa3 34.Qxf7+ Kh6 (34... Kg5 35.Rf5+ and mate next) 35.Nf5+ Kg5 36.Nxg7 looks winning. D) 27... Re7 28.Ne6+
D.1) 28... Nxe6 29.Qxd6+ Kb7 30.Qxb6+ Ka8 31.Qb8#.
D.2) 28... Kb8 29.Qxd6+ Ka8 (29... Kxa7 or 29... Kb7 30.Qxb6+ Ka8 31.Qb8#) 30.Qd8+ and mate in two. D.3) 28... Kd7 29.Nxg5 + - [Q vs R+3P]. |
