| Jul-27-06 | | KholdStare: Wow totally missed it. This is a great sacrifice--and a much harder puzzle than yesterday's! (First, but who cares? :D) |
|
| Jul-27-06 | | Infohunter: Impressive. First White sets up a Knight sacrifice to deflect Black's threat to corner his King, then pushes the Pawn with a mate threat, gaining another move to push it to the seventh. And Black's outside passed Pawn had looked as though it would have such great potential, too! |
|
| Jul-27-06 | | Tariqov: Wow,nice, got it:).if you look at other possibilities this is the only logical one,as White must have something here as Black threatens Qxf2 or Qh3+ etc.The only one that checks is Ne7 + and Nxg6+,as Qh8+ does not lead anywhere,and after you find out you can play a quiet move as everything is secure for the king, d6 comes straight away. |
|
| Jul-27-06 | | Gregor Samsa Mendel: Got it. *pats self on back*
But would I have seen this had I actually been playing? And even if I had seen it, would I have had the guts to play it? *shrugs shoulders* |

 | | al wazir: <Tariqov: if you look at other possibilities this is the only logical one>: My thinking exactly. |
|
| Jul-27-06 | | dzechiel: Got it, and pretty quickly. The key part was noticing that 39 d6 not only advanced the pawn, but also gained a tempo due to the mate threat. A pretty combination, and one that had to be forseen in order to play 36 Qf6. |
|
| Jul-27-06 | | Brent Baccala: Notice black's offered sacrifice on his 35th move. He's playing for a draw by this point. |
|
| Jul-27-06 | | Fezzik: Wow,
I was impressed by this one. Of course, the key move of the variation after 38.Nxg6+!! Bxg6 39.d6 wasn't 39...Kg8. The key move was either 39...Qd1 or 39...Qd3. The game would have continued 40.Qe7+ Kg8 41.d7!Another variation that White had to calculate was 39...Bf5 40.Qxf5 Qd1 and I would play 41.Qc8+ Kg7 42.Qc3+ f6 43.Qxa5 Qxd6 44.Qxh5 unless I found some way to queen the d-pawn/win Black's Queen after the time control at move 40. I wonder at what point Yusupov saw this combo. |
|
| Jul-27-06 | | Fezzik: Addendum: In the line I gave with 39...Bf5, if Black plays 42...Kh6 instead of f6, White wins with 43.Qd4! |
|
| Jul-27-06 | | Fezzik: Oops, I was missing that White threatened mate on h8 after 39.d6! It isn't a quiet move at all! |
|
| Jul-27-06 | | pebble767: I saw it...yes! Removing the mate/ perpetual plus having a winning passed pawn. I actually saw the move right away but I'm trying to make sure that it's going to win. Then I realized that the only way to stop temporarily the passed pawn is to remove the queen it its current perpetual longing position, which will result in lose of tempo because of check in black's king. |
|
| Jul-27-06 | | bernardchinshin: I think White had to play forcing lines seeing that Black threatened checkmate. |
|

 | | An Englishman: Good Evening: This was a complete surprise--I solved it. But if it had been 36.??? or 35.???, there is no way I would have seen the win. Just no way. |
|
| Jul-27-06 | | jahhaj: I thought this was quite easy. Both sides have big threats so there are only a limited number of possibilities. |
|
Jul-27-06
| | al wazir: <An Englishman: if it had been 36.??? or 35.???, there is no way I would have seen the win.> I'm not sure there is a win after 35. Qe5+. Suppose black had played 35...Kh7. If now 36. Qf6 Bf5, white's only alternatives are (A) giving perpetual check with 37. Qxf7+ Kh8 38. Qf8+ Kh7, etc.; (B) allowing black to give perpetual check after, e.g., 37. Ne7 Qxf2+; or (C) defending the f ♙ by, e.g., 37. Qb2, in which case black plays 37...Be4! and wins. |
|
| Jul-27-06 | | goldfarbdj: I almost but not quite solved this one.
I saw that black was threatening a perpetual, so that white had to play with checks. I saw 37. Ne7+ and verified that 37. ... Kh7 38. Qxf7+ led to mate. After 37. ... Kf8 I considered 38. Nxg6+. I noticed that after 38. ... Bxg6, 39. d6 would threaten mate. What I missed was that after Bxg6, white's Q protects f2. |
|
| Jul-27-06 | | 2ndNature: Saw the whole lot rigth through - don't think it was Thursday's level material. |
|
| Jul-27-06 | | nikolajewitsch: 37.Ne7+ is easy to see; 38. Nxg6 should have been the puzzle. |
|
| Jul-27-06 | | jahhaj: <nikalojewitsch> Of course 38.Nxg6+ is the puzzle! You have to see the whole variation not just the first move! |
|
| Jul-27-06 | | jahhaj: <al wazir> After 35...Kh7 White can still get his queen round to f4 after picking up the f7 pawn. E.g. 35...Kh7 36.Qf6 Bf5 37.Qxf7+ Kh6 38.Qf8+ Kh7 39.Qe7+ then 1) 35...Kh6 36.Qg5+ followed by Qf4
2) 35...Kh8 36.Qe5+ followed by Qf4
3) 35...Kg8 36.Qd8+ followed by Qc7+ and Qf4
In all these lines, having secured his own king, White is then going to win by pushing his d pawn and checking Black's king |
|
| Jul-27-06 | | Richerby: I hate it when I see all the ideas but not how to combine them. OTB I think I'd have gone for 37.♘e7+ ♔f8 38.♘xf5 and Black gets the draw. Maybe I'd have got lucky once another move had been played on the board. |
|
| Jul-27-06 | | zabbura2002: White has no other option than giving a check since 37. ... Qxf2+ is fatal. The problem is to find a suitable continuation after 37. Ne7+ |
|
| Jul-27-06 | | nikolajewitsch: <jahhaj> I agree with you, but still i prefer the difficult move to be the one thats asked for; oterwise it can give you this feeling of having solved the puzzle hal-way through becuase you might have found the first move (that was asked for) but not the entire line... |
|
| Jul-27-06 | | EmperorAtahualpa: Brilliant! Didn't see it at all. Was assuming 38.Nxf5, winning a pawn. |
|
| Jul-27-06 | | zb2cr: Saw the key moves 37 and 38. But I didn't see it all the way--after 39. d6, threatening mate, my board vision took a vacation. I could see Black's perpetual threat had been met, but I couldn't seem to calculate the best defense. |
