Jul-02-05  Gowe: Great puzzle. I was really shocked when i saw the combination, very simple indeed but very complicated. I was like 20 seconds until i saw Qe6!! winning the rock. Just wonderful. Now it looks so simple, i can't believe it. Great job by Polugaevsky!

  OhioChessFan: The line in the game was fairly easy for a Saturday. But the Rd1, Qe6 was a little tougher.
Jul-02-05  paulchess: Wait .... if 33.rd1 is followed by Qe6, white just initiates the Q exchange and then takes the black rook. Did everyone here miss something or am I wrong ?
Jul-02-05  Gavagai: <paulchess> 34....Rxd1+ 35.Kg2 fxe6 Black takes the white rook and checks the king so the queen cant escape the f pawn
Jul-02-05  kevin86: This was a very easy Saturday puzzle. If white interposes at d1-black plays Qe6. Then he intermezzos Rxd1+,if white takes the queen.
Jul-02-05  awfulhangover: I gave up. Didn't see Qe6. Maybe Hydra is better than me after all ...
Jul-02-05  EinZweiDrei: I also missed ...Qe6. Otherwise would have been more of a Wednesday puzzle.
Jul-02-05  euripides: White is under tremendous pressure after 30...e4. However, 31 Qb1 is interesting e.g. 31...Rd8 32 Qc2 (if 32 Nc4 Qf3+ or 32 Nxe4 Rxd1 33 Nf6+ Kg6 34 Qxd1 Qxf6) ) Qh5 ? (threatening Qe2 and if 33 Kf1 Qxh2) 33 Nxe4 ! and if Black takes on d1 White has 34 Nf6++ ! leading to mate. So better 31 Qb1 Rd8 32 Qc2 g6 ! and then perhaps 33 h4 Rd3 34 Kf1 Qd5 35 Ke2.

Now White is totally trussed up because a knight move will lose to Qh5+ , but how does Black break through ? A possible winning plan is Kg7 and f6 followed by g5 when White must either (a) give Black an outside majority by hg fg or (b) accept a vulnerable h pawn after ...gh gh or (c) advance with h5. After (a) and (b) Black manoeuvres his king to the best position, exchanges everything off on d2, and should be able to get an outside passed pawn in the K+P ending. If (c), Black wins the h pawn with his queen while keeping White tied up (e.g. Qg4 followed by Rd7 and then and then Qxh5), then brings his queen back to the d file and exchanges everything off.

The difficulty with this plan is that White can give disruptive checks with the queen on the c file. Unfortunately, the black queen is needed on d5 rather than d7 to protect the e pawn, and if Black plays f5 the plan with g5 does not work.

Not trivial.

Jul-02-05  filipecea: 1987... Is Polugaevsky still alive?
Jul-02-05  paulchess: <Gavagai> Won't white play 34....Rxd1+ 35.Qxd1 so it is dead even and black cannot force the win. Still seems to me that 33 Kg2 is a blunder for white.

  Chessical: <filipecea> Polugaevsky died in Paris on the 30th August 1995.
Jul-02-05  cade: <paulchess> 33.Rd1 Qe6 34.Qxe6 Rxd1+ 35.Kg2 fxe6

White is a whole Rook down.

Jul-02-05  Shokwave: Funny...I looked at Qe6 several times in other lines, and felt that BxN was necessary...but failed to get them together in the right order. I couldn't figure out how to deflect the white Q from gaurding the rook; in all lines it got to the back rank and defended. Frustrating to have all the key moves, but not manage to get them in the correct order and make it work.
Jul-02-05  Happypuppet: Yikes. I calculated everything I could and came up with the position after 33.Rd1 several times, but didn't even analyze anything in that position because I thought White had sufficiently defended. I should be more on the lookout for unprotected pieces. :(
Jul-02-05  sfm: After a couple of days with easy ones this was was hard. I spent some time on 31.-,♖c3 and 32.-,♖d3 which also wins. But as it was a little "undramatic" for a front-page puzzle I started looking for something else.

What a surprise for spectators to see white move 33.♔g2 when 33.♖d1 looks so obvious!

<coolthing76 ..a grandmaster move that both players of this game saw...>

Right! It is quite possible that Petursson may have been stupefied for a second when Polu plays 31.♗xd2 which seems to be a such weak move compared to ♖c3. Then comes the horror when he three seconds later discovers that it is all over. He knows his fate when he recaptures on d2...

  WannaBe: I think, if white played Rd1 to block, black should then play Qd7. Unless I missed something. For somoe reason, I saw today's puzzle.
Jul-02-05  ThomYorke: CanĀ“t black win a piece by playing ♖d8 and then ♕d7, for example?
Jul-02-05  filipecea: Thanks <Chessical>
Jul-02-05  The beginner: I missed it. like <Happypuppet> I dident analyse further after 33 Rd1 :(

Key to the puzzle is seing 34 Qe6 where white cant exchange Queens because black has the "inbetween" move 35 ..Rxd1+ leaving black a rook up.

32 ..Bxd2
33 Rxd2 ..Rc1+
34 Rd1 ..Qe6
35 Qxe6 ..Rxd1+
36 Kg2 ..fxe6

<ThomYorke>

31 ..Rd8
32 Nc4 and white should be ok.

Jul-02-05  Gowe: <WannaBe> if 33.Rd1 Qd7 and now the simply 34.Rxc1 and black is a rock down.
Jul-02-05  Gowe: <Thomyorke> The last answer is for you too. If you play Qd7 you just lost the rock.

  WannaBe: <Gowe> D'oh!!! Allow me to repeat myself here... D'oh!! I did miss something... :-(
Jul-02-05  Koster: White pressed hard for the advantage with 14.Ra2, but black found the correct reply, 14...Ra7!
Jul-05-05  patzer2: The puzzle solution and the move played with 31...Bxd2! makes for an instructive attack on the weakened castled position.

Perhaps the most interesting move is the double attack that occurs after 33. Rd1!? Qe6!! , as discussed above, when Black wins as White must surrender either the Queen or the Rook.

Jul-05-05  patzer2: The waiting move 33...Rg1! is note worthy, leaving White helpless against the dual threats 35...Qh5# or 35...f5 followed by 36...Qg4#.
