 | | Moondoll: Hooray for monday puzzles! I also took longer trying to figure out why Qd8+ wasn't the right move. |
|
| Apr-24-06 | | DeepBlade: Waiting for wednesday... |
|
| Apr-24-06 | | dakgootje: Think chessgames.com wants to learn us that youve got always have an eye at your own and your opponents backrank, as those things and queen sacs are common in monday puzzles. Indeed a easy puzzle, as mondays are for, but probably this is the only way that you are gonna look at those things in your own games too, so nice to keep such puzzles as mondays. For myself, partly because i visit this site and party because im not the weakest player (okay, problem solver), this kind of puzzles are mostly intuinitive, and i think this is for most of us here around... |

 | | LIFE Master AJ: Oh no! Not the back-ranker!
(Hey, its Monday, what did you expect?)
How did Bareev miss this? (Blindfold!) Uh, OK ... I guess. |
|
| Apr-24-06 | | YouRang: Very easy, even for Monday. It left me with just one obvious question, but that was answered when I saw that this was a blindfold game. |
|
| Apr-24-06 | | Castle In The Sky: I saw this as soon as I looked at the puzzle, if there is such a thing as instantaneous solving. TGIM. |
|
| Apr-24-06 | | Nomen Nescio: It would have been much harder for me to solve this puzzle blindfolded. |
|
| Apr-24-06 | | kevin86: I cannot "Bereev" could make such a silly blunder as his last move. The solution was easy-back rank mate stands out like a size 17 shoe. |
|
| Apr-24-06 | | GeauxCool: <kevin86> - It was Amber. |
|
| Apr-24-06 | | dbquintillion: <Nomen Nescio> I agree. Blindfolded chess problems are extremely difficult. |
|
| Apr-24-06 | | TOOEASY: I love to hear those stupid, "Too Easy" comments. Keep it up!! |
|
| Apr-24-06 | | kevin86: I was referring to solvers of the problem-not Mr. Leko-who was blindfold-meaning:he was not seeing the board as he played. He was instead,using his mind's eye. |
|
| Apr-24-06 | | ChessPieceFace: technically i didn't get it, because i said white to mate in two, but really it was black to resign in one. haha! one for one this week. :) |
|
| Apr-24-06 | | SilveredSpirit: Puzzles like these make people feel much better after having just been clueless the day before :p |
|
| Apr-24-06 | | Bradleyson: I too was wondering how he didnt see that, and i still am. What is a blindfold match exactly? Is he just not allowed to see the board and is only given the opponent's moves? |
|
| Apr-24-06 | | Halldor: <Bradleyson> The players have blank boards on a computer screen, as seen on some of the pictures here: http://www.chessbase.com/eventartic... |

| Apr-24-06 | | Knight13: This puzzle was so hard I couldn't beleve it. It was so easy to miss Qd8+ that it took me 90 minutse to figure this problem out.... Man... I think a 2700 would solve it a lot quicker. |
|
| Apr-24-06 | | kewmschess: I'm more interested in the position before 33... Qf3. If Black doesn't blunder, is there a way to force one of the defenders off the back rank? |
|

 | | OBIT: <kewmschess> I analyzed the position before 33...Qf3, which you'll see on page 1. I was curious how my analysis would compare to a computer analysis (mine wasn't done with a computer), just to see if I missed anything significant, but no one has put this one on their computer yet. Personally, I think it'd be worthwhile for someone to do that - this looks like an instructive attacking position to me. |
|
| Apr-26-06 | | Cyphelium: <OBIT> I haven't used a computer either, but I've allowed myself some remarks anyway. After 33.- ♕b8 34. ♕e7 ♕c7, it's true that 35. ♖d7 wins, though 35. ♕xc7 seems faster. After 33.- ♕b8 34. ♕e7 ♘h5 35. ♖d7 a6 36. ♗d5 ♖e8 37. ♕f7 ♖f8 38. ♗f3 ♖xf7 39. gxf7 g6, you suggest 40. ♖e8, but the rook is on d7, so it's not possible. This means that white has to play 40. ♗xh5 gxh5 41. ♖e7 ♕f8 42. ♖e8 ♔g7 43. ♖xf8 ♔xf8, which doesn't look like a very promising pawn endgame. If nothing else, after 33.- ♕b8 34. ♕e7 ♘h5 35. ♖d7 a6, white could try 36. ♖b7 ♕a8 37. ♗d5, with the prosaic idea of picking up some pawns. After, say, 37.- ♖e8 38. ♕c7 ♖c8 39. ♕xb6 white wins, and 38.- ♕c8 39. ♕xc8 ♖xc8 40. ♖xb6 is a lost endgame. I agree though that it would feel better if there was some knock-out blow instead. |
|
| Apr-26-06 | | patzer2: If this had not been a blindfold game, I don't think Bareev would have made the blunder 33...3?? when 34. Qd8+! yields a quick two-move back rank mate. |

| | OBIT: <Cyphelium> Thanks very much for sharing your notes on the position before 33...Qf3. First, I have to agree that 35. Qxc7 is faster after 33...Qb8 34. Qe7 Qc7. In the critical line 33...Qb8 34. Qe7 Nh5 35. Rd7 a6 36. Bd5 Re8 37. Qf7 Rf8 38. Bf3 Rxf7 38. Bf3 Rxf7 39. gxf7 g6: 40. Re8 was a typo. I intended 40. Re7 - but that's an error, since Black can defend everything by 40...Ng7. (By the way, 40. Re7 does work if Black plays 39...Nf4?) So, you did find a major hole in my analysis. Yes, I was pressing for a knockout blow, which is not an easy task in this position. For example, after 33...Qb8 34. Qe7 Nh5 35. Rd7 a6 36. Bd5 Re8 37. Qf7 Rf8, I also looked 38. Re7 a good while. The idea behind the move is to stop ...Rxf7 and continue Bf3 followed by Bxh5; however, 38...Qd8! seems to hang tough. Another try is 38. Ra7. This time I thought the rook and bishop could work together to preclude 38...Rxf7 - but nope, 38...Rxf7 39. gxf7 g6 40. Ra8 Qxa8 41. Bxa8 Kg7. White position after his 33rd move certainly looks good, but proving the win sure is tough for my feeble mind. Those guys who solve the weekend puzzles in under ten seconds should tackle it. |

| May-07-06 | | kewmschess: I didn't let it run for long, but Fritz (v8) thinks Black's best is 33...Rf8 and didn't even look at 33...Qb8. White wins by piling up on the 7th:
33. a3 f8 34. ♕d7 ♘e2 35. ♕e7 a5 36. ♖d7 ♕e4+  with White having an advantage of 1.33 pawns.When I forced it to look at 33...Qb8, it gave the main line as
33. a3 ♕b8 34. ♕e7 ♘h5 35. ♖d7 a5 36. ♗e6 ♖e8 37. ♖b7 and gave White an advantage of 1.69 pawns. |
|
| Jan-24-09 | | WhiteRook48: nice. why 33...Qf3?? |
