 | | dzechiel: Black to move (24...?). Black has a pawn for a knight. "Difficult." Black must be careful in this position, in some lines white can get in Qa8+ (which may be mate depending on whether black can interpose on e8). It really seems to me that the first move should be
24...Qe5+
I like this move because white has limited legal replies, and most of them lose on the spot. For instance, 25 Qg3 allows 25...Qxg3+ (duh), but also 25 Kh1 seems to lose quickly to 25...Qe1+ 26 Rf1 (not 26 Kh2 Qg1#) 26...Rg1+ 27 Kh2 (not 27 Rxg1 Qxg1#) 27...Rxf1 28 Qa8+ Qe8 and black finds himself up the exchange and a pawn. Nope, I think white needs to play
25 Qf4 Bxf2
and once again black is up an exchange.
On further consideration, the line I gave as a variation is probably the main line and 25 Qf4 is the unplayed move. Time to check. |

 | | rhickma4: Black is a piece behind, and moving the Q may allow Qa8+
So the logical forcing move order is:
24...Qe5+ 25.Kh1 (25.Qc4 allows 25...Bxc2).
Now 25...Qe1+ 26.Rf1 Rg1+ 27.Kh2 (27.Rxg1 Qxg1#) 27...Rxf1
Black is now the exchange and a pawn ahead with multiple threats which cannot all be countered as 28 Qa8+ can be met with Qe8 |

|
| Jun-24-11 | | VincentL: "Difficult" (presumably, level not specified).
What can I write? I didn´t solve it.
I did actually consider the first few moves played, but in the wrong order. Null points today. |

I had to solve this, since I'm nowhere near as good as Carlsen. Black's down a piece for a pawn, but there's some pressure on White's king. The pawn on d3 looks interesting, but d2 and d1 are well guarded. Of course, if the pawn could capture on e2, that's a different matter. White has back rank potential with Qa8+, so it's probably a checking game. That means <24...Qe5+>. 25.Qf4 Bxf2 wins a rook since Black's queen is protected, so <25.Kh1 Qe1+> and <26.Rf1> is forced. Now if 26...Qe2 were check we might get that trade on e2. How can we get there? Ah, <26...Rg1+> looks like a key move! That forces <27.Kh2>, and 27...Rxf1 is possible since Black can interpose his queen on e8 after 28.Qa8+. Is there something more forcing? I chose 27...Qe2+, for 28.Qxe2 dxe2 when White can't stop the pawn, or 29.Rf2 Qxf2+ 30.Qxf2 Bxf2, with an exchange up in what seems an easy ending. I see Carlsen chose <27...Qe5+>, forcing <28.Qf4 Rxf1>, settling for the exchange up ending. Don't see anything wrong with 27...Qe2+, thouch, and 27...Rxf1 might also work though it's less forcing. So I think that 26...Rg1+ is the move to find to claim a solution. |

| Jun-24-11 | | jheiner: 24. Black to play. Material P for N. Black has a passed P on d3. Q is hanging. White has a battery on the f-file, but more dangerously has back rank mate threats, especially Qa8 if Black's Q
moves poorly.
24...Qe5+ 25.Kh1
If 25.Qf4 Bxf2 and White can't recapture due to the pin. White is up the exchange with a passed P and Q's coming off the board. 25...Qe1+ 26.Rf1
If 26.Kh2 Qxb1?? fails to Qa1#, but Qg1# works fine.
26...Rg1+ 27.Kh2
If 27.Rxg1?? Qxg1#
27...Rxg1 and now 28.Qa8+ is harmless as Black still has Qc8. The theme here is dark squared weaknesses and pins. While Black is down in material, the White B and N are too far from the White K to support. Black's DSB exerts tremendous pressure on the a7-g1 diagonal. The Qe5+ check forces the White K into territory where Black can take advantage. Time to check. |

| Jun-24-11 | | TheBish: M Pavlovic vs Carlsen, 2006 Black to play (24...?) "Difficult"
Not too difficult... I worked it out in my head -- as Carlsen had to, assuming he found it (and I am) -- but it took me a few minutes. In contrast to yesterday's (where looking at forced captures led to the solution), today looking at a forced checking sequence provided the answer. 24...Qe5+ 25. Kh1
Forced, as 25. Qf4 Bxf2 wins a rook due to the pin, leaving Black up an exchange, but it gets worse: 26. Qxe5 (forced) dxe5 and add another passed pawn to the total. 25...Qe1+ 26. Rf1 (forced) Rg1+!
Pretty obvious, as 27. Rxg1? Qxg1# ends things quickly. 27. Kh2 Qe5+ 28. Qf4 Rxf1
Thanks to the pin, Black has won the rook and has an easy win, an exchange and a passed pawn ahead. |

 | | sevenseaman: 24...Qe5+ gives Black the balance of power as his f2 R stays
under the sword, rendering blocking the check with Q a futile
option.
<24...Qe5+ 25. Kh1 Qe1+ >(Black could have taken the exchange but
this is more forceful, because using the attacked R on f1 is no
relief on a/c of the availability of Black R on 'g'
file. Makes the mopping up that much more facile.)
<26. Rf1> (for want of anything better)
<26...Rg1+> (the hammer blow)
<27. kh2 Qe5+ 28. Qf4 Rxf1 29. Qxe5> (A normal exchange but here an
admission of defeat)
<29...dxe5 0-1>, rest of the moves are the obvious last rites; there
may be quite a few.
Summation <24...Qe5+ 25. Kh1 Qe1+ 26. Rf1 Rg1+ 27. Kh2 Qe5+ 28. Qf4 Rxf1 29. Qxe5 dxe5 0-1>

| Jun-24-11 | | SamAtoms1980: Well, I went with 24....Qe3, so that if 25.Rf1 Qe2+. The right general idea, but the wrong way. Like Thor in the movie "Thor," I advanced when retreating, with 24....Qe5+, was better. A neat point is that if 25.Qf4 Bxf2 wins the rook which the pin left hanging. |

| | sevenseaman: As compared to yesterday, most solvers are hitting the right buttons today. |
|
| Jun-24-11 | | Quentinc: If 25. Qf4, I had 25...Qe1 26. Rf1 (seems pretty much forced) Qe2+ 27. Rf2 Bxf2 with an immediate win. But, of course, that's only because I didn't see the obvious 25...Bxf2. Somehow I had in my mind that taking the rook wasn't a profitable possibility because it only won back the exchange. |

 | | Jimfromprovidence: I like the way black simplified at the end, playing the straightforward 28...Rxf1 instead of 28...Qe2+, which is the stronger move but might allow white a check at h6 with his queen (after 29 Rf2 Bxf2) and some running for black’s king. Here's the position after 29...dxe5.
click for larger viewIf white plays something like 30 Na3 or Ba2 instead of the text move, then black can play 30...e4, connecting his passed pawns, supported by bishop and rook, winning easily. (30 Na3 e4 below).

But if not 26. Qxe2, where is the white to go?> <al wazir> 25...Bxf2, 26. Qa8+ Qe8, 27. Qxe8+ Kxe8.  But 25...Qe1+ is much better than 25...Bxf2.

 | | M.Hassan: "Difficult" Black to play 24...?
Black has a pawn for a Knight.
Black should bear in mind that if White Queen can go to a8 with a check and the King can not be defended, it is checkmate. Therefore, it is of paramount importance that Black holds the e file and keep checking the White King: 24...........Qe5+
25.Kh1 Qe1+
26.Rf1 Rg1+!!
27.Kh2 Qe5+
28.Qf4 Qe2+
29.Rf2 Bxf2
Now Black can breathe easier and in fact can inhale lots of fresh air. White Queen can not go to 8th row,he has taken a Rook and one discovered check by Black can checkmate White.White can keep checking the King but will not have chance of winning. Time to check |
|
| Jun-24-11 | | Dr. J: The line I saw was 24...Qe5+ 25 Kh1 Bxf2?! 26 Qxf2 Rxf6, and since White must lose considerable further material, it could be argued that this is also a solution. |
|
| Jun-24-11 | | tacticalmonster: 24 Qe5+ 25 Kh1 (25 Qf4 Bxf2 26 Qxe5 dxe5 ) Qe1+ 26 Rf1 Rg1+ 27 Kh2 Rxg1 |
|
| Jun-24-11 | | KingV93: I liked e5+ but thought that Black would play  xf2 and  xf6 as follow up moves, not seeing  h1. Not bad though. |
