| Mar-07-06 | | LivBlockade: ♘d6 - a little tricky for a Tuesday. Nice puzzle. |
|
| Mar-07-06 | | LivBlockade: I spent time looking at ♘g5, but ♕xf6 defends the f7 and h8 squares, so White's attack leads nowhere. |
|
| Mar-07-06 | | Fezzik: I had to spend several minutes on this one. I like positions like this. GM Gulko had defended against all the obvious threats, but White still seemed to be overwhelming. The key was to find out how to use the overworked Queen and rook theme against Black. Polugaevsky found a beautiful way to do it. Great finish and an even better choice for a puzzler. For those who complain that this is a bit hard, remember that this is essentially a "White to move and win in one move" position. Again, a great choice! |
|
| Mar-07-06 | | Fezzik: PS: The game incorrectly gives Boris Gulko as representing the United States in this tournament. At the time, he was still a Soviet citizen. He and Lev Alburt are the only two players (as far as I know) who won both the Soviet Championship and the US Championship. This win by Polugaevsky, who was one of the World's best players at the time, was truly well-deserved. |
|
| Mar-07-06 | | LivBlockade: After White's 22.♗g5, what happens if Black plays 22...♘xe5? |
|
| Mar-07-06 | | patzer2: Today's puzzle solution is the neat clearance and double attack move 28. Nd6!! The double attack involves more than a simple Knight Fork, as White also has the threat of a quick mate after 28...cxd6 29. Rxe6!  . In the final position, Black has nothing better than 28...Qxf6, allowing 29. Nxe8 Qe7 30. Rxe6! fxe6 31. Qxg6 Kf8 32. Nf6+ , with White having decisive material and an easy win. |
|
| Mar-07-06 | | dzechiel: <LivBlockade: After White's 22.Bg5, what happens if Black plays 22...Nxe5?> It looks like 23 Nxd4 followed by 24 Qe2 to me, but that's just a real quick look. |
|
| Mar-07-06 | | notsodeepthought: <LivBlockade> Probably he didn't like 22 ... N:e5 23 N:d4 - though given the way the game turned out... |
|
| Mar-07-06 | | blingice: Ah yes, there is the double threat of losing the rook for nothing if Nd6, because I looked at Ng3 for a while, and when I saw I was wrong, I had a difficult time of figuring out why, until I realized the double threat, soon to be inevitable mate a few moves later. I dislike it when a piece has to move one way or the other, and there is no clear cut way (within 2 ply, :P) to see a win. |

 | | An Englishman: Good Evening: The problem becomes easy once you realize that if White were a Knight down (yes, remove the Knight from the board), Rxe6 would present itself to you like a tiger presenting itself to its prey. So it becomes a simple matter of figuring out how best to get the excess Knight out of the way with tempo and without losing the f-pawn. |
|
| Mar-07-06 | | Soltari: Easy tuesday, spotted the right move almost immediately. I solved it by removal of the guard, in order to mate on g7, black's knight has to be removed. To remove black's knight, white's knight has to move to create a discovered rook attack. Now where should white's knight go? Nd6 forks queen and rook, and forms a good double attack.
Nice puzzle. |
|
| Mar-07-06 | | Mating Net: Looks like CT-art problem 484.
<An Englishman> & <Soltari> provided excellent commentary. |
|
| Mar-07-06 | | JoeStrummer: I found N-g3, which I think wins also. Black can play Q-g5, but after RX N, and R x R +, white will lose his queen but play his K to g5 and force mate. Does this work? |
|
| Mar-07-06 | | logo: Joesstrummer, after Ng3 black plays Qxf6 (then if Nxh5, Qh8) |
|
| Mar-07-06 | | prinsallan: Got this, but it was hard for a tuesday. I also looked at Ng5 first, but found the text move without difficulty in about a minute. |
|
| Mar-07-06 | | sldr989: It all comes down to the tactics. In this case removing the guard. Not a bad puzzle. I recommed 303 Tricky Chess Tactics by Wilson and Albertson |
|
| Mar-07-06 | | simsan: Didn't get it. I saw the Qxf6 refutation of Ng5, but it looked so "nice for a tuesday" that I refused to believe it. :-( The idea of removing the Ne6 is obvious. The idea of moving your own N to achieve it is also quite apparent, but I wanted to scare the N away so I could attack the Re8 (retrospectively thinking of yesterdays back rank puzzle). I got stuck on that pattern of thought, and finally decided that there might be some sweet continuation for white after Ng5 that I didn't see. Only now do I see that the only effective way to deal with the possible countermove Qxf6, is Nd6, and that after cxd6 Rxe6 the troublesome N is definitely gone. |
|
| Mar-07-06 | | Benzol: <Fezzik> I hate to be nit picky but only Boris Gulko has won both Soviet and US Championships. Lev Alburt has been US Champion but didn't win the Soviet Championship. See my post in The Kibitzer's Café |
|
| Mar-07-06 | | gus inn: a very fine comment <Fezzik > ! Bravo.
Yes ; just pretending that the Knight isnt at the board and almost everyone will spot Rxe6 in a short time.Hence Nd6 could easily be discovered "backwards". |
|
| Mar-07-06 | | EmperorAtahualpa: Quite a hard puzzle for Tuesday in my opinion! I didn't find it. :( My idea was 28.Ng5 but, like others, I didn't calculate 28...Qxf6! |

 | | LIFE Master AJ: This is a position that has been published in several trap books before. (I knew the solution immediately, because I recognized the position ... although I did not remember who the players were.) The solution is quite logical. It would be easy to classify the first move as a fork. Actually its more of a clearance move ... so that the White Rook can get at the Knight on e6. (The Black Knight on e6 is the glue that holds Black's position together.) Thus 28.Nd6!, PxN; 29.RxNe6, and Black cannot defend the g7-square. How to classify this problem? I would say it would come under the heading of, "destroying the defender," but maybe some might not agree with this. |
|
| Mar-07-06 | | guybrush: Does Ng3 count as a solution? |
|
| Mar-07-06 | | WarmasterKron: I had the principle of this one (the black knight is protecting the mating threat so it must be removed), the discovered attack on the knight and the attack on the queen, but I was working with 28.Ng3?, not noticing ...Qxf6! destroying the bulk of white's threats. |
|
| Mar-07-06 | | Catenaccio: <How to classify this problem? I would say it would come under the heading of, "destroying the defender," but maybe some might not agree with this.>
I would classify it as "How to win a rook", since the best way to continue for black would be, as far as I can see:
28. ... Qxf6
29. Nxe8 Qh8
30. Qxh8 Kxh8
Against my girl-friend I would still go for the win as black.
Or does anyone see a quick mate after 29.? |
|
| Mar-07-06 | | DexterGordon: <guybrush>, 28.Ng3 fails for the same reason that 28.Ng5 does, namely 28...Qxf6. See <logo's> post above. |
