 | | Open Defence: <Wannabe> Actually i didnt.. geez so I need to sign up a few 100 times and create a game collection each time for this to be added??? |
|
| Jun-18-07 | | srinivas6195: easy game for vishy anand
|
|
| Jan-17-09 | | WhiteRook48: great game by Anand. |
|
| Aug-09-14 | | patzer2: If 27... Qd8, then it's mate-in-two with 28. Qh6+ Kg8 29. Ne7#. |
|
| Aug-09-14 | | morfishine: Again, Timman is on the short end of a brilliancy
I found <25.Rxh7> fairly quickly noticing that after 25...Kxh7 White has <26.Qh2+> forcing 26...Kxg7 After that, I had a difficult time deciding on the direct attack with 27.Rxg6+ or 27.Nxg6 with a dangerous exposed check I was able to follow the game continuation but thought after 29.Nxc8 Black could fight
on awhile after 29...Bxd4
Sometimes, I have to be satisfied with the progress I did make ***** |
|
| Aug-09-14 | | harshvk5: Doesn't 29. ... Bxd4 result in 30. Qxd6+, recapturing either the bishop on d4 or the knight on d7? IMO there's no adequate reply to the check on d6. |

 | | al wazir: I think 25. Qh2, 25. Rxg6, and 25. Nxg6 also win. I couldn't choose a favorite from among all those alternatives. |
|
| Aug-09-14 | | Once: <al wazir: I think 25. Qh2, 25. Rxg6, and 25. Nxg6 also win. I couldn't choose a favorite from among all those alternatives.> Yup, I was in a similar position, although I narrowed the choice down to 25. Rxh7 and 25. Nxg6. Both seemed to give white a comfortable advantage although not a forced mate. In the end, I opted for 25. Nxg6 in human mode.
Fritzie rates this is "Ja, Ja, das is nicht bad. Fur ein human..." After five minutes of beard stroking and pipe twiddling on my (admittedly slow) laptop, this is what he says: 25. Rxh7 (+5.67)
25. Nxg6 (+2.84)
25. Rxg6 (+1.29)
Others are broadly level or black is better. So I guess my pick of 25. Nxg6 is a silver medal. |
|
| Aug-09-14 | | Cheapo by the Dozen: I imagine the start is 26 Nxg6 -- note that the knight is poisoned -- which could continue 26 ... Rxg7 27 Bh6. Indeed, that's what I'd play in a speed game, because if it goes badly White will still probably only have given up 2 pieces for a rook, hopefully a pawn or 2, and an attack. But I'm not going to try to calculate the whole thing out at this point in the morning. |

 | | perfidious: <fgh: Wow, solved in 1.2 seconds.> Rough go of it, compared to posters who doubtless nailed it in mere nanoseconds, as always. (wink) |
|
| Aug-09-14 | | Once: <perfidious> Yes, but that was back in 2004 when just about every puzzle was solved in nanoseconds. And the main aim apparently was to finish faster than the previous kibitzer. |
|
| Aug-09-14 | | Cheapo by the Dozen: Whoops. I overlooked ... Rxg6 |
|
| Aug-09-14 | | Rookiepawn: I think this one is not very difficult, I solved it quickly (not in nanoseconds, but maybe nanominutes), the weakness in g6 is easy to spot and from there not many variants arise... I failed miserably in easy and medium ones. I guess it depends on many factors, including if your brain is having a good day or not. |
|
| Aug-09-14 | | agb2002: This position is a serious candidate for overworked puzzle: it is #125 in Kalinin's "Great Chess Combinations. Vishy Anand" and diagram #10 of chapter 2 in McDonald's "Starting Out. 1 e4!" (the whole game is commented) just to mention two examples I can remember right now. |
|
| Aug-09-14 | | Steven87: I got the basic ideas. Got lazy and stopped short of working out an exact line involving both Rxh7 and Nxg6. Maybe if I'd had my coffee first |

30.Qxd6+ seems to wrap it up.
In the puzzle position

I also went with <Once's> 25.Nxg6 - winning a Pawn safely and exposing the King a bit more - not the best but good enough. If 25...Rxg7 26.Rxh7 seeing 26...Rxh7 27.Ne7+ or 26...Kxh7 27.Qh2+ Kxg6 28.Qh5# Finally if 26...Kh7+ 27.Qh2+ Kg8 28.Ne7+ picks up the Queen for some wood. I would be delighted if <Once> could post Black's best defence according to Herr Fritz. |
|
| Aug-09-14 | | kevin86: I saw the rook sac to get it started, but fuzzy after that: Typical Saturday! |
|
| Aug-09-14 | | King.Arthur.Brazil: After some minutes, 25.Rxh7 and ticks. Sometimes the position call it self for attacking sacrifice, I didn't doubt to do it. I refused black capture the R, by simply 25... Kxh7 met 26.Rxg6 followed by Qh2+... Qh8#. So, if 26...Sxg7 27.Qh2+ Kg8 28.Nh5 seemed to get winning chances. 26... Rxg7 27.Qh2+ Kg8 28.Rxf6 followed as soon as possible by same 29.Nh5... Actually Anand reply wins directly. But, at board I would analyse more. But Rxh7 I would play firstly and would think there after... |
|
| Aug-09-14 | | Once: <David2009> My version of Fritz on a relatively slow machine struggles a bit with this position. Others packing more silicon oomph may have more luck. Fritzie reckons that black's best after 25. Nxg6 is the surprising 25...Rxe3. 26. Rxg7 Re1! 
click for larger view27. Rxe1 Kxh7 28. Rh1+ Kg8 29. Rg1
click for larger viewBlack is a piece up, but he has nowhere safe to park his king or queen. Amongst other things, white threatens to sacrifice another piece with 30. Nf5+ exf5 31. Ne5+ Kf8 32. Qxd6+. In fact, from this position Fritz wants to give up his queen with 29...Nb5 allowing 30. Ne7+. The eval is now over +5. Returning to 25. Nxg6 Rxg7, the evals take a nose dive with 26. Ne7+ Bxe7 27. Rxg7+ Rxg7 28. Nf5+! 
click for larger viewA second piece sac! According to Fritzie, 28...Kf8 is the only move to avoid mate. For example, 28...exf5 29. Qg2+ Kf8 30. Rxh7 Ne6 31. Qg6 
click for larger viewBlack can't defend against Rh8# and Qf7#.
Going back to the position after 28. Nf5+ Kf8 white has an overwhelming attack starting with 29. Nxe7. The remaining white pieces are going to flood into the space around the black king. The evals are now north of +12. After all this sliding backwards and forwards, Fritzie now thinks that 25. Nxg6 is actually stronger than the game continuation of 25. Rxh7. |
|
| Aug-09-14 | | Once: Addendum ... after 1½ hours of infinite analysis, 25. Rxh7 is back in the lead. It has an eval of +6.12 compared to 25. Nxg6 which is scoring +4.85. |
|
| Aug-09-14 | | MarkFinan: Maybe I should look a little harder at these Wednesday onwards puzzles because as usual I just glanced and looked at Qh2? completely missing that black can take the pawn with the rook. But *if* black was stupid enough to take with the Bishop I think this is a better puzzle to solve... There's a forced mate in 9.

| Aug-09-14 | | M.Hassan: "Very Difficult"
White to play 25.?
White has a Knight for a Bishop
25.Rxh7 Kxh7

<if...Kxg7 27.Ne7+ and Black Queen is lost
26.........Bxg7
27.Qh2+ Kg8
I could not proceed beyond this point, and I was doubtful of my move of 25...Kxh7 and Chessmaster confirmed it as below: 25.Rxh7 <Bxg7>

Looks like I had made right moves but in wrong order

| Aug-09-14 | | dfcx: As a puzzle, I found 25.Rxh7, knowing there is some good move. 25.Rxh7 Kxh7? 26.Qh2+ Kxg7 27.Nxg6! Rxe3

| Oct-26-17 | | MrMcgoo: On move 24. I entered hxg and lost a point.
If I had added the superfluous 7 to make it hxg7
i would have gotten the full 3 points. This is not the first time Olga has made this mistake. Please fix it.
Thanks |

 | | plang: 10 Be3 is a relatively new idea using a tempo to set up an attack similar to the English Attack in the Najdorf (f3 followed by g4 and g5). The justification is that the bishop on d7 is awkwardly placed taking up the retreat square for the f6 knight. 10..Rc8?! does nothing to meet White's attacking plans; Seirawan recommended 10..h5 which is now the most popular move. 11..Na5?! was not very effective here; 11..Nxd4 12 Bxd4..e5 13 Be3 would have been better (Anand: "Timman is not used to playing the positions ensuing from the English Attack, so he opted for another plan"). Anand was willing to lose a second tempo with 13 Bd3 to retain his dark-squared bishop. 16 g5 was well timed as 16..Nh5 was no longer playable due to 17 Ng3 (both 17..g6 and 17..Nxg3 18 gxh are in White's favor); after 17..Ne8 the knight was very passively placed. |
