 | | sevenseaman: Hi <The Last Straw>. (The problem no is #93877). Good. You have understood the idea involved and also found out that 1. Qc3 is bad (refuted by 1. Qxh2 or Qf2). The Q at c2 is right. Here the Q is immune on a/c of 2. Nxf7# This is what happened in the CT computer (ideal);
<1. Qc2 Qd4 2. Qg2 Qxg1 3. Qxg1 >  This is how the game (between Saric-Gurevich)went OTB. 1. Qc2 Qxf6 2. Qxc7 Rf8 3. Nd7 Qd8 4. Qc3+ d4 5. Qc5 Rg8 6. Qxd4+ f6 7. Rxg8+ Qxg8 8. Nxf6 Qf8 9. Ne4+ |

Looks to be rather a simple position. First reaction is take the B and when the R takes your R back, check with the Q and take the importunate R. Very easy, should not be much more than 1800.
Still the problem is rated at 2200 with a failure rate of 63%. 3...Qxa2 4. Ra4 is the catch that nullifies your effort. That is why you need to think harder.
The cure is;
3...Bc5 4. Rf2 Bxf2 5. Qxf2 Qxe4 and you win.
2) #96797
click for larger viewWhite.
The way to go about it is;
1. Qf1 h5 2. Qxc1 Qxc1+ 3. Rf1+ Kh7 4. Rxc1
Why not Rf1+??
1...Kh8 and now our R is pinned (if 2.Rg1 Rxg1+; 2.Re1 Qd2; 2.Ra8 Rxa8, 3.Bxa8 Qf4) Another pitfall is 2.Rc7+ Kh7! (2...Qxd5 should lose) 3.Qxc1 Nf2+ 4.Kg1 Nh3+ perpetual tough? that it indeed is.
3)#60942 Elaborate Preparation
This is a position that I had posted in your forum on May-7-13.

Black.
White's Q is hanging but Black plays <1...Rxh8+ 2. Bf1 Rxf1+ 3. Kxf1 Bh3+ 4. Kg1> before taking the the White Q <4...Nxe5 >. Just why?
Of course the White Q was going nowhere, but why would Black incur the expense of losing an exchange before taking the hapless Q? No one has analysed the problem. The white Q cannot be grabbed early. Unless the B moves out of c8 (w/o loss of tempo of course), White has a draw via a perpetual. Viz; 1... Rxh1+ 2. Bf1 Rxf1+ 3. Kxf1 Nxe5 4. Nc7+ Kb8 5. Na6+ = by repetition. |

| | sevenseaman: Hi< The Last Straw>. The position is zugzwangish for White. Black covers all bases and plays 1...Qb8. He threatens 2...Bg3+ and White has no good moves to survive. |
|
| May-13-13 | | The Last Straw: <sevenseaman>Yes, 1... b8! is correct. After 2. f3 how should black continue? |
|
May-13-13
| | sevenseaman: Hi < The Last Straw>. An immediate R or Q move cannot be good for Black. He should simply exchange his B and follow up with 2...R8h5. With all bases for Black secured White is toast now. Its an interesting study for a chess thinker. 1...Qb8 was the point that mattered. It forces White to weaken his position, no matter what he does thereafter. The best book on Domination is by Ghenrikh Kasparyan called Domination in 2545 Endgame Studies. Its like a dictionary on how to attain domination in endgame situations. Very comprehensive, better than Nalimov Tables as most of the time it deals with more than 4 pieces on board and yet has a similar approach. |

| | sevenseaman: #99296 Domination
Domination in chess is the art of reaching a winning position in as few moves as possible. Study the following position carefully. 
click for larger viewWhite.
My first impulse was to play 1. e5 which forces the N to move. On second thought I said , so what the N moves - how will that help me. So I chose to first pin the N by <1. Rhg1> and Black had to react. <1...Kh8>. <2. Qh6>, I maneuvered my Q to a better place so that f6 would be a killer. <2...Rg8 3. Nd5> putting the N on a command square from where it can jump to f6. <3...Bxf5> Black is forced to react again in order to foreclose the move I was always threatening to make. <4. Nf6> Black is lost, he cannot save his R without losing the game. So <4...Qxf6 5. Qxf6> harakiri was in order.
'Domination' is complete.

The sol ran counter to all my calculation(only later I found it was flawed). So I put it up if anyone else can think like TogaII. Dashing, very pretty and indeed logical. |

| May-13-13 | | Mr. Happy: <sevenseaman> Hi! I'm User: The Last Straw (check morfishine chessforum for proof). 1...b8! 2.f3  xc1 3. fxc1 xg2 actually wins. Try to find the mate after 4.xg2. |
|
| May-14-13 | | Mr. Happy: Game link: A Kitchlew vs M Fraser, 2000.
(Don't worry, in this game, white didn't play 4.xg2). |
|
May-14-13
| | sevenseaman: Hi <Mr. Happy>! We can see that all 3 White pieces are hors de combat, so Black mates as he pleases, without any interference. One version is; 4...Qh2+ 5. Kf1 Qf4+ 6. Ke2 Rh2+ 7. Ke1 Qf2+ 8. Kd1 Qe2 or Qd2# Rather than belabor a minor point, better if you posted your solution after my first response, in case you deem it inadequate. |

If you look at the material count you do not have a ghost of a chance even if you took out one of his Qs. So a stratagem? Hun? A feint, a hook and a haymaker. |

| May-14-13 | | Mr. Happy: <sevenseaman> Oh, I'm sorry. I used to do it the other way with <morfishine>, but thanks for telling me what you prefer. 2.Black to play
click for larger viewThis ending looks relatively hard for black. How should he draw? |
|
| May-14-13 | | The Last Straw: BTW, I made a mistake. The pawn on h7 is a white pawn, not a black one. |
|
May-14-13
| | sevenseaman: <Mr. Happy>. The way I look at your problem is; 1...Ng6 2. kc5 Ka6
Now White can only move his K whereas Black will keep oscillating his N between g6 and h8 for a draw. |

<1...Rb1 2. Rc1 Rxc1 3. Qxc1> is sparring, normal warm up punching. But
<3...Nd4 > is sublime. It clears the light diagonal for the Black Q to check from a1 and devour the White Q. (In the solution it happens; <4. Bxd4 Qa1+ 5. K~ Qxc1  >). But should White obtusely ignore the N at d4 & try to wriggle out his K, this happens instead; 4. Ke1 Qe4+ ( 4. f3 Qxf3+ 5. Kg1 Ne2+ ) 5. Kd1 Qe2#
What kind of value do you place on <3...Nd4> seeing that it is not <easy> to think of? |
|
| May-14-13 | | Mr. Happy: Yes, 1... g6! is correct. White cannot get through, as 2.e6 f8+ draws.2.d6
(2.c5 a6! 3.d6 (3.b4 h8! 4.a4 g6 =) xa5 4.c7 b5 5.d8 c6 6.e8 d6 7.f7 h8+ 8.g7 e7! 9.xh8 f8 =) 2...b8! 3.c6

3...c8! 4.a6 b8 5.b6 h8! 6.c5 c7! 7.a7 b7 8.d6 g6! 9.a8+ xa8 and the game was agreed a draw. |

The game continued 1...e3 2.c7+ f8 3.c8+ g7 4.c7+ f8 5.c8+ e7 4.c7+ e8 5.e7+ and after white took the bishop black played ...h6 and won. However, there is a prettier line. Black could have played... 1...h6!! 2.xh6 xg5+! 3.xg5 e3+ 4.h5 xh6 5.xh6 a5! 6.h7 a4 7.g4 a3 8.g5 a2 9.g6+ f6 10.g7 a1 11.g8 h1#.

Continuing my hunt for killer moves I present this peerless move, not at all easy to find (a rating of 2332.3 is evidence enough). And what a beauty, I'd go miles to see! 1. Rd1 Qxe5 <2. Bc5> and Black resigned. Why? |

click for larger viewWhite.
Those who are familiar with Panno's chess, he almost always came up with brilliant, novel looking moves. This is no run-of-the mill either. Definitely out of the compass of routine chess thinking. I did have an alt for 1. cxb5 but Panno shunned it altogether. I went on to play <1. Rg4+> (that many of us may have come up with). <1...Kf8>. But here Panno wrought a miracle, a masterpiece of unusual thinking; <2. Nd7+> and now you may have wised up to what is going to happen. (I did after I had spent a whole day and a long journey thinking of Nd7+ and its aftermath-these days I am never in a hurry to solve, there being no dead line. When the thought occurred to me I felt I had attained Nirvana; what bliss!) <2...Rxd7 3. Re8+! Kxe8 4. Rg8#> What a marvel <morf>! Who makes a place so that he could peacefully sac a R? |

click for larger viewBlack.
At least for me this puzzle was no joke. It took my sweat and blood and I felt very proud having come through a terribly complex sequence. Hard calculation is a time-consuming, taxing thing. I do not give myself many airs but its certainly for solvers who can concentrate for a <length> of time. It took me all of 22:57 minutes but I was mentally prepared to go another hour. My first thoughts had a blow out and were abandoned;
1... Qxb7, 2.Rxf7 Kh8 3.Bxd4 Rg8 4.d8=Q! Raxd8
I had no choice but to embark on a difficult journey, with some diffidence but less hope. <1...Qxb7> (inescapable) <2. Rxf7 h5> (part of a long plan) <3. Bxd4 Kh7> (a must) <4. Be6>( expected)<4...Qc6!!> (took me ages) <5. Rxg7+ Kh6!> ( a payback!) <6. Bf5 Qd6> (positioned for battle) <7. c3 Qxd4+> ( a hard but inescapable sac)
<8. cxd4 Kxg7> (the prize dividend). What d'ya say? |

After a little thought, <1...Qc3+> simply stands out. You'll easily see White cannot parry it with either the R or the B. His best response equally stands out, <1. Kd1>. Now what? N move obviously but where? My hasty choice was <2...Nxe4> mainly because it collects a P. Some more thought and I prefer <2...Ng4>. It gives me a good option of Ne3+. But now a great defensive idea of <3. Qxa7> sickeningly dawns on me, negating both Ne3 and Nf2 checks. Whither now? Ah yes... <3...Rb1> with Qb3+ in the RVM. But <4. Rc2> is a spoilsport. But hold it, <4...Nc3+> floats back into the arena. And you know it inexorably claims the White Q now. <5. Qxe4 Qxe4> Q.E.D. |
