| Jul-13-07 | | kevin86: Is this some sort of a record? A queen and SIX pawns vs two rooks-WOW!!
White was in a little danger of last row mate threats on the back row but black was never able to even threaten one because he was too busy fending off queen and pawn moves.
This week's theme seems to be forks-there have been more forks this week than at a formal dinner. |
|
| Jul-13-07 | | Crowaholic: <willyfly: After 24 Rxd5 exd5 25 Ne7+ then 25...Kh8 or Kh7 and I played 26 Qh5+ which is refuted by interposing the Black Q.> That's the Zwischenzug problem, I had a lot of trouble solving some recent puzzles because I failed to see the proper Zwischenzug. One day I will make a checklist to use whenever I'm stuck trying to solve a puzzle. One point will be something like "You're trying to achieve something but X interferes? Try a Zwischenzug to remove or deflect X, or to interfere with its movement." Then, many days later I will not need the checklist any more. Hopefully. :-) By the way, my analysis for 25. ..Kf7 26. Qh5+ Kf8 27. Qh7 Kf7? contains a blunder. I suggested that this transposes into the text line after 28. Nf5 Qg6 29. Re7+ Qxe7 30. Nxe7.
I missed the crushing and rather obvious Zwischenzug 30. Qxg7+! and now ..Ke6 31. Nxe7 or another Zwischenzug 31. Qe5+ It's funny, but I didn't see this while looking at the virtual board and then I realized it some time later when playing the puzzle through in my head, without even seeing the position. |
|
| Jul-13-07 | | zb2cr: Initially, I dismissed the idea of 27. Qh7 as in the game, because it seemed to me that Black would just play 27. ... Kf7, with a perpetual. Obviously, White can't play 28. Qxg7+, Kxg7; 29. Nf5+, K(any); 30. Nxd6, Rxd6, as he's a Rook down. Can anyone tell me what White's response in that line should be? 28. Qh5+, Kf8; 29. f5 followed by Re6 seems promising. |
|
| Jul-13-07 | | willyfly: <Crowaholic> <One day I will make a checklist> haha - how many times have I said that to myself - and - from this day forth I shall look for all possible ♘ forks <Zwischenzug> where's the Chessplayer's dictionary? |
|
| Jul-13-07 | | TrueBlue: my vote goes for f5 |
|
| Jul-13-07 | | bogo78: < JG27Pyth: Isn't 27...Kf7 black's best defense for draw? > Then 28 Nf5. This threatens Qg7# and also puts the question to the black Q. So the Q must move and in the same time defend the g7 square. So 28...Qf6 is forced. Now white has at least 29 Re7+ when 29...Qxe7 is forced. Now 30 Qxg7+ followed by Qxe7 and black can resign. |
|
| Jul-13-07 | | patzer2: Today's puzzle solution is the decoy and clearance sacrifice 24. Rxd5!!, which sacs the exchange to clear the e-file for the follow-up 25. Ne7+! in order to flush out the Black King for a little pursuit (combination). |

 | | fm avari viraf: White's position looks very rosy & so 24.Rxd5 is the only move that gives him a winning chances. 24...Qxd5 is not possible because of the fork on e7. Of course, White has to be very precise since 25.Re6? would give Black a chance for resurrection with 25...Re8! & White can't capture the Queen because of the back-rank mate. Therefore 25.Ne7+ Kf7 if Black King moves to h8 or h7 then 26.Re6  .26.Qh5+ Kf8 27.Qh7! Kf7 I saw this move instead of text but 28.Nf5 Qf6 29.Re7+ Qxe7 30.Qxg7+ Ke6 & 31.Ne7 but 31.Qxe7+ wins as we have seen in the game. |
|
| Jul-13-07 | | bakuazer: I got the first 3 moves right. Then there are variations, and it was difficult(for me) to calculate all of them. But I had in my mind that it may lead to endgame where whites having more and better pawns will help. I guess i can count full point for myself for this (good) puzzle. |
|
| Jul-13-07 | | MiCrooks: Well...Qxe7 is not actually forced or even best, but it is true Black is dead lost after 28. Nf5 after 27...Kf7. Black can step up after Qg6 Re7 Kf6, but then White STILL has Re6!! White will end up picking up the Bishop and have Q+N against two inactive Rooks. Would be a much quicker ending. |
|
| Jul-13-07 | | Timex: Rxd5 forces exd5 other wise Ne7+ forking the king and queen. This was a relatively nice puzzle. Although i got it instantly, and I'm sure other people did too, it was quite instructive. You can see that the rook was pinning the knight to the queen and that the queen was covering the e7 square. The exchange sac is the perfect way to gain control over the e7 square. No matter what piece black uses to capture, lines to the king will be opened up and the vital e7 square under white's control. After move 24, the rest of the game is just checks and pushing the king around the board. The Queen drives the king up the board and gains material in the end. |
|
| Jul-13-07 | | LivBlockade: After 25... ♔f7, I planned 26. ♘f5 which seems at least as good as 26. ♕h5+. So after 25... ♔f7; 26. ♘f5 ♕f6, Black threatens mate, but White has 27. ♖e7+ reaching a position similar to the game. Against other 25th moves by Black's King, I planned 26. ♖e6, with lines such as 25... ♔f8; 26. ♖e6 ♕c7; 27. ♕f5+ ♔e8; 28. ♘xd5+ with a winning discovered check. |

| Apr-30-23 | | Brenin: 24 Rxd5 exd5 25 Ne7+ Kf7 26 Qh5+ Kf8 seemed clear, but I didn't see 27 Qh7. This was analysed very thoroughly in 2007. |
|
| Apr-30-23 | | Brenin: Black was doing fine until the pointless 16 ... b4 (Rac8 was better) and then 17 ... Rfd8 which left f7 weak and allowed the B sac 19 Bxh7+. If 19 ... Kxh7 then 20 Qh5+ Kg8 21 Qxf7+ Kh8 (or Kh7) 22 Rd3 is deadly. |
|
| Apr-30-23 | | jrredfield: It took me at least 20 seconds but I chose 24 Rxd5 exd5. I should have seen 25 Ne7+ but missed it and wasn't sure how to proceed. It appears to me that this becomes a battle which eventually allows White to gain the advantage with a few Kingside passed pawns, allowing for an endgame win. I wanted to see how this would play out, so I consulted Komodo Dragon 3.1 and see this line: 24 Rxd5 exd5 25 Ne7+ Kf8 26 Re6 Qxe7 27 Rxe7 Kxe7 28 Qxg7+ Kd6 29 b3 Rg8 30 Qf6+ Kc5 31 Qe7+ Kc6. 32 g4. Now White is slowly able to get the pawns in motion although it will be a hard-fought journey to move them far enough along to take command. |
|
| Apr-30-23 | | TheBish: This looked familiar to me, I believe it's a puzzle on one of my phone apps. Still had to solve it again, because it's been some time. But once you look at 24. Rxd5, it all falls into place. |

 | | scormus: I thought I could bask in the satisfaction of a rare Sunday solve when I made it all the way to 29 Qxg7+, only to find that was just the start. Another 18 moves of work ahead!
Not sure if all the moves of both sides to 29 were the best, but they looked reasonable to me. |
|
Apr-30-23
| | scormus: .... only move I was unsure of was 25 ... Kf7, I'd forseen 25 ... Kf8 26 Re6 Qxe7 etc., which I notice <mel> SF gives. Doesn't seem to differ much from the text. Other tries to defend look worse for B. |

| Apr-30-23 | | agb2002: White has a knight and three pawns for the bishop pair. Black doesn't seem to have clear threats, except eventually back rank mate chances, but a funny line is Bxa2+ Kxa2 b3+ Ka1? Qa3+ Kb1 Qxb2#. White would like to reach e7. This suggests 24.Rxd5 exd5 (24... Qxd5 25.Ne7+ wins decisive material) 25.Ne7+ (24.Rxe7 Qf6 looks bad for White): A) 25... Kf7 26.Nf5 (26.Qh5+ Kf8 [26... Kf6 27.Qg6#] 27.Qh7 Kf7) A.1) 26... Qg6 27.Re7+ Kf6 28.Re6+ Kxe6 29.Qxg6+ Bf6 30.Nd4+ Ke7 31.Nc6+ wins decisive material. A.2) 26... Qf6 27.Re7+
A.2.a) 27... Qxe7 28.Qxg7+ (28.Nxe7 Re8) 28... Kf6 29.Qxe7+ Kxf5 30.Qxb4 wins decisive material. A.2.b) 27... Kf8 28.Rxg7
B) 25... Kf8 26.Re6
B.1) 26... Qxe7 27.Rxe7 Kxe7 28.Qxg7+ wins decisive material. B.2) 26... Qc5 27.Qf5+ Bf6 (27... Ke8 28.Nxd5+ Kd7 29.Rf6+ Ke8 30.Qe6+ and mate next) 28.Rxf6+ and mate in two. C) 25... Kh7 26.Re6 Qxe6 (26... Qc5 27.Qh5+ Bh6 28.Qxh6#) 27.Qxe6 is winning (27... Re8 28.Qf5+ and mate in two). D) 25... Kh8 26.Re6 as above. |
|
| Apr-30-23 | | King.Arthur.Brazil: The King's line is: 24. Rxd5 exd5 (24... Qxd4?? 25. Ne7+ it wins the ♕, The King loves it! , You know... ) 25. Re6 Qd7 26. Ne7+ (a) Kh7 27. Qh5+ Bh6 28. Qxh6# or (b) Kh8 27. Qh5+ Bh6 28. Qxh6# or (c) Kf8 27. Qf5+ Bf6 28. Qxf6+ Ke8 29. Qg6+ Kf8 30. Qg8# or even 27... Ke8 28. Ng6+ Qxe6 29. Qxe6#.
Therefore, Black must find another answer to 25. Re6, which will avoid the dangerous Ne7+. Maybe, 25... Qxe6 26. Qxe6+ Kh7 27. Qf5 and they're still under dangerous attack. The advantage of my proposal is that Black King would not escape. If 25... Qc5 26. Ne7+ Kf8 27. Qf5+ Ke8 28. Nxd5+ Kd7 29. Rf6+ Ke8 30. Qe6+ Qe7 31. Qxe7#. But, as <Brenin> certainly would say, Black can escape with 25... Re8, when White cannot capture the enemy's ♕ due to back rank mate. I always forget that I'm analyzing other persons' games... I always provide an air to my beloved King before a tactical attack... |
