 | | doubledrooks: 25...Qd3 puts enormous pressure on the white position by threatening 26...Qxe4 and 26...Qxf1#. White has no good response, as others have noted. |

|
| Apr-21-10 | | awfulhangover: Yes!, I found the correct move!!
But it took me at least 10 minutes, so I felt stupid. Glad to see so many of you failed, hehe. |
|
| Apr-21-10 | | YouRang: I missed it, but I guess I can at least "brag" that I dismissed 25...Qxd1 due to 26.Qxc4. What bugs me more is that I looked at 25...Qa2 (getting my Q out of take while maintaining guard or Bc4, which is attacking Rf1), but failed to notice that black has no good way to avoid losing the rook for a bishop (e.g. 26.Re1 Bc3). :-( |
|
| Apr-21-10 | | orior: When I saw the solution I thought it was one of the cases where the player misses "the solution", but there was no "Here white missed the winning Qxd1" annotation :) Only then, after checking again and trying to find out what's the problem with that move, I saw that hanging C4 bishop.. At least we are all in a good company :) |
|
| Apr-21-10 | | turbo231: The chess engines preferred Rxd1. Although in one of the games Rybka's first move was Qa2! Now that was interesting! |

| | benveniste: I spent too much time on ♕xd1 and eventually ended up at ♕a2. But at least according to the computer, I then slipped by grabbing the exchange too soon. Great puzzle, CG! |

| Apr-21-10 | | VincentL: "Medium/Easy".
White has various threats: mate with Qe8# if the black rook moves off the 8th rank; also
the capture of the queen with Bxb3.
The move I see for black is 25.... Qxd1. Then if 26. Rxd1, 26....Rxd1+ 27 Kg2 Bd5
winning the white queen. If 28. Qxd5 Bxd5+, black emerges a rook up. However.... white can play 26. Qxc4 and now I don't see how black can gain the upper hand. Let's try a different starting move, 25... Qd3. After 26 Qxd3 we have 26.... Bxd3
27. Re1 Bc3 winning the rook.
Is this the solution?
White can also play 26. Qg2, but then white continues 26.... Qxf1+ 27. Qxf1 Bxf1 28. Kxf1 Rxd1+ followed by
29.... Rxc1, emerging a rook up.
This must be it.
Time to check. |

| Apr-21-10 | | Patriot: I didn't spend much time on this and saw the possibility of 25...Qxd1 since if 26.Rxd1 Rxd1+ 27.Kg2 Bd5 winning a piece. However I saw where some said the simple 26.Qxc4 refutes the attack. Congrats to every one who solved this. I'm just wondering what everyone would have done here during a game. Obviously you can't look at every single move as a puzzle, but it is very clear the position is critical and requires you to think carefully depending on the time remaining and time control. |
|
| Apr-21-10 | | VincentL: I see that many thought that Qxd1 was the solution, so I am a bit chuffed today. Usually it is I who fall into the "trap" and others who see the correct line. |
|
| Apr-21-10 | | DarthStapler: I picked Qxd1 like several other people |
|

 | | gawain: Mea culpa. I, too, fell for the 25...Qxd1 illusion. And I was so pleased with myself for seeing that 25 ...Rxd1 fails because of the back rank mate, I was sure that the queen capture was it. |
|
| Apr-21-10 | | lost in space: Missed it. I was working on Qxd1 |
|
Apr-21-10
 | | fm avari viraf: After a cursory glance, the first move that flashed into my mind was 25...Qxd1 but soon realised that 26.Qxc4 would make Black sweat for a win. Hence, the most simply move 25...Qd3 would win the exchange & the game. |

Medium/easy
25...
Things to take into account:
Black has a hanging Queen and weak back rank. Why not get rid of this?
25... Qxd1! Leading to 26.Rxd1 Rxd1+ Kg2 Bd5! 0-1 |
|
| Apr-21-10 | | RandomVisitor: White went astray at move 18, when best was perhaps:
click for larger view Rybka 3:
<[-0.17] d=23 18.Rd2> Rxd2 [-0.48] d=22 18.Rc2 Bc4 19.Nc3 Qb6 20.Qxb7 Qxb7 21.Bxb7 Rab8 22.Bg2 |

| Apr-21-10 | | wals: Rybka 3 1-cpu: 3071 mb hash: depth 20:
Material was even, White stumbled on -
19.Rd2 (-1.33) better was Rc2 (-0.63)
and tripped badly on -
24.Bf3 (-3.15) better was Ba3 (-1.27)
Rybka calculated 25...Qa2 (-3.30) as being better than the text move
Qd3 (-3.15). |

| | anthro: Like many others, I fell for Q x d1. The correct response by black seems quite obvious once it is shown. It is an interesting question why so many of us missed it. Was it because this was a puzzle and the misleading sequence we all "saw" seemed like a solution to a Wednesday puzzle. Would we have made the same mistake in a game? |
|
| Apr-21-10 | | Funicular: "Would we have made the same mistake in a game?"
Probably. But we'd get a won game anyway. Anyway, "when you find a good move, look for a better one" right :)? perhaps today's puzzle is one of the finest examples of that statement BTW, i saw Qxd1 and stopped looking any further ;) |

Qxc4! - then Black gets nothing. Bruno Parma's correct move - 25...Qd3! leads to double attack (threatening 26...Qxe4 or 26...Qxf1# so, it's much stronger than 25...Qxd1?). Take a look at <Eduardo Leon>'s commentary as follows: 26. Qg2? Qxf1+!, 27. Qxf1 Bxf1, 28. Kxf1 Rd1+, 29. Ke2 Rxc1  SuperPatzer77 |
|
| Apr-21-10 | | turbo231: I set my position up wrong again, I set the white Queen at f4 instead of e4. That's makes a big difference. |
|
| Apr-21-10 | | SamAtoms1980: <TheaN: 3/3
Woah woah!! Roughly 80% of the regulars going for Qxd1? That's.... spooky. What did you guys smoke?> Look outside your window..... We were all raiding the warehouse as you spoke :-) |
|
| Apr-21-10 | | patzer2: A more popular alternative in this opening, especially at the super GM level, is 7. Qc2 as in Gelfand vs Topalov, 2010. |
|
| Apr-22-10 | | kevin86: black most needed to avoid his own back row disaster:25...♖xd1?? 26 ♕e8# OUCH! |
|
| Apr-22-10 | | rapidcitychess: <Super Patzer> After reading many a lament about Qxd1, I changed my mind.;) |
