| Aug-14-14 | | morfishine: Interesting comments, particularly those related to "other" moves. I figured <26.Rxg6> was the move, so stopped there never fathoming White could sac the Queen 26.Rxg6 Kxg6 27.e5+ f5 28.Qg4+ Kh7
(or 28...Ng5 29.Nxf5)
29.Nxf5 Qf8 30.Nxd6+ Bf5 31.Bxf5#

| Aug-14-14 | | greenfield67: Well, I think the b1-h7 diagonal is the go here, so let's open it with 26.e5. Assume Black closes it again with 26...f5. Then 27.Nf5 steals a pawn and weakens g6 again. Now 27...gf5 28.Qh5+ Nh6 29. Qg6# looks convincing. Alternatively 27...Bf5 28.Bf5 and the bishop can't be taken because of the same mate via h5 and g6, so carnage follows on g6 and elsewhere. So it looks like the knight can't be taken on move 27, but there's no great square for the Black queen, and White has won a pawn with a raging attack and can feast at leisure. Although now that I look at the comments above, 26.Qh5+ is pretty cool - and I might well have overlooked some defensive resources. |

| Aug-14-14 | | David2009: Black misses his big chance in the diagram position:

The Graceful Loser coup! Since his position is clearly hopeless Black's best is follows:
1. Very careful consideration sitting at the board for a few moves;
2. When White returns, capture the Queen and play out the forced sequence 26...gxh5 27.e5+ f5

3. As soon as White plays 28.Nxf5 stand up quietly with a beaming smile, shake White warmly by the hand with finger to the lips, put the pieces back very quietly, sign the score sheets and silently gesture to the adjudication/ analysis room. The Graceful Loser coup!
It is so important to accept Queen sacrifices in hopeless positions - otherwise the search engines won't recognise that they have been made. |

 | | agb2002: White has the bishop pair for a bishop and a knight. The pawn on g6 limits the range of the rook on g3 and the bishop on d3. This suggests 26.Qh5+: A) 26... gxh5 27.e5+ f5 (27... Bf5 28.Bxf5#) 28.Nxf5 (threatens 29.Rg7# and 29.Nxe7+ Bf5 30.Bxf5#) A.1) 28... Qf8 29.<K moves, except Ng7>+ Bf5 30.Bxf5#. A.2) 28... Nxe5 29.dxe5
A.2.a) 29... Qf8 30.Nxd6+ Bf5 31.Nxf5 wins.
A.2.b) 29... Ba6 30.Bc2 wins.
A.3) 28... Rg8 29.Nxe7+ Rg6 (29... Kh8 30.Rxg8#) 30.Rxg6 and White has a mating attack and an extra rook. B) 26... Kg7(8) 27.Qxg6+ Kf8 28.Ng4 (threatens Nxf6)
B.1) 28... Rg8 29.Qxg8+ Kxg8 30.Nxf6+ Kf(h)8 31.Rg8#. B.2) 28... Bxg4 29.Rxg4 and White has an overwhelming position and an extra pawn. |

| Aug-14-14 | | hedgeh0g: A nice puzzle. While White has a myriad of crushing continuations at his disposal (including e5 and Nf5) Qh5+ is the most forcing and thus easiest to calculate. My main line went: 26.Qh5+ gxh5 27.e5+ f5 28.Nxf5 Qg5 29.Bxg5 Nxg5 30.Rxg5 Bxf5 31.Bxf5+ Kh6 32.Rg6+ and White clearly has an enormous advantage. |

| Aug-14-14 | | zb2cr: I saw thet the Queen sacrifice works if accepted, but was unable to work out the variation if it was declined (as it was in the game). |
|
| Aug-14-14 | | Nick46: medium to very difficult |
|
| Aug-14-14 | | Pawn Slayer: I'd have played e5 without a second thought.
The queen sac never occurred to me. |
|
| Aug-14-14 | | meetvirgo2005: I considered both Qh5+ and e5 and opted for Qh5. However Houdini suggests e5 as better. |
|
| Aug-14-14 | | dx9293: Wow...I have played against both of these players. Not only that, I was at this tournament, though I don't remember this particular game. Memories... |

 | | Sally Simpson: Stopped looking after Qh5+ that wins no need to go further. There is a chess playing program called Waxman by Ivan Bacigal. I'm Wondering if there is any connection. I can think of no better gift to your girlfriend than to name your chess playing program after her.
That is true love. |
|
| Aug-14-14 | | The Rocket: Took me less than a second. |
|
| Aug-14-14 | | TheTamale: I'm probably overlooking the glaringly obvious, but I can't see what White does after 31) ...Qf8. |

| Aug-14-14 | | patzer2: Nakamura's sham Queen sacrifice 26. Qh5+!! initiates a brilliant combination to solve today's Thursday puzzle. However, it's only one of many winning moves. Like <meetvirgo>'s Houdini, Fritz 12 program evaluates 26. e5! best, but at 17/46 depth on a 2.1 GHZ dual core processor Fritz 12 finds 18 winning possibilities (including my choice of 26. Nf5!). Here's the top seven Fritz 12 choices: 1. (8.62): 26.e5 Kg7 27.Rxg6+ Kf8 28.exf6 Qe8 29.Qf3 Ne6 30.Re1 Nxd4 31.Qg3 Qd8 32.Bc4 Be6 33.Bxe6 Nxe6 2. (7.68): 26.Qh5+ gxh5 27.e5+ f5 28.Nxf5 Nxe5 29.dxe5 Qf7 30.Nxd6+ Bf5 31.Bxf5+ Qxf5 32.Nxf5 Rg8 33.Rh3 Ne6 34.Be3 Rgb8 35.Rxh5+ Kg6 36.Ng3 Rc8 3. (4.92): 26.d5 Ne5 27.Nf5 Qf8 28.dxc6 Ndf7 29.c7 Nxd3 30.Rh3+ Kg8 31.Rxd3 Be6 32.Nxd6 Rh4 33.Bg3 Rh8 4. (4.46): 26.Nc4 Kg7 27.Nxd6 g5 28.e5 Kf8 29.Nxc8 Rxc8 30.exf6 Qxf6 31.Be3 Ne6 32.Rf3 Qh6 33.h3 5. (4.44): 26.Nd5 cxd5 27.exd5 Kg7 28.Rxg6+ Kf8 29.Qd2 Rb8 30.Re1 Ne5 31.dxe5 dxe5 32.Be3 Ke8 33.Qf2 Qd6 34.Qxf6 Qxf6 35.Rxf6 6.

| Aug-14-14 | | kevin86: I was trying to find the correct sacrifice, but missed it. :( |
|
| Aug-14-14 | | e4 resigns: I got it up to 28. Nf5. |
|
Aug-14-14
 | | Jimfromprovidence: I also went with 26 e5, below.
click for larger view The main threat is a mating net beginning with 26 Rxg6, followed by 27 Qh5. |
|
| Aug-14-14 | | zb2cr: To <TheTamale>:
<Jausch46> provided the solution to that in earlier kibitzing. |
|
| Aug-14-14 | | thegoodanarchist: <Once: ... Fritzie is currently saying that the best move in the position is 26. e5, which never occurred to me.> But we humans know that the best move is the winning move that is most beautiful, so while e5 may get the highest evaluation, Qh5+ is still the best! |
|
| Aug-14-14 | | vajeer: I went with 26.e5 I think Black's best response is still 26...Kg8. I think best continuation then is 27 exf6. Anyone knows what Fritzie is saying? |
|
| Aug-14-14 | | Lighthorse: To <TheTamale>:
I think the response to ...Qf8 is:
1. Bxd6
since 1...Qxg7 then 2.Nxg7#
since 1...Nxd6 then 2.Bxd7# or 2.Qxd7#
On any other response, black loses his Queen and has a lost game. Perhaps my favorite continuation after ...Qf8 would be:
1. Bxd6 Nb7
2. Bxf8 0-0-0 (Finally!) |
|
| Aug-14-14 | | Lighthorse: BTW..re. 0-0-0
I don't know WHAT I was thinking. Remind me never again to set up a position and go do something else for a while! |
|
| Aug-18-14 | | TheTamale: Thanks to <Lighthorse>, <zb2cr>, and, of course, <Jausch46>. And don't feel bad, Lighthorse, I love that continuation as well... but in my case, simply because it's cheating. "Win if you can, lose if you must, but always cheat." --Jesse Ventura |
