| Feb-12-09 | | zb2cr: I was looking for a way to combine the Ne6 threat and the Qf7+ move. Then I saw the game line. Took me some little time, perhaps 90 seconds, but after
33. Qf7+, Qxf7; 34. gxf7+, Kxg7; 35. Rxg7+, Kf8; 36. Ne6+, Rxe6; 37. Rxd8+, Re8; 38. Rxe8+, Kxe8; 39. Rg6 White wins another Pawn and is up the exchange and two Pawns. |
|
| Feb-12-09 | | The beginner: Pretty easy for a thursday. almost all of it is forced. |
|
| Feb-12-09 | | nimzo knight: I feel there has been not much consistency in difficulty level this week. This puzzle looked easier to me than yesterday. |
|
| Feb-12-09 | | zb2cr: As to 38. Rdd7 being better than 38. Rxe8+, Crafty sees the former as being +4.09 at 18 ply, the latter being +5.02 at 18 ply. |
|
| Feb-12-09 | | whiteshark: Got it. I even calculated a bit further with <36...Rxe6 37.Rxd8+ Re8 38.Rdd7>. |
|
| Feb-12-09 | | Patriot: This practically plays itself out if you look at forcing moves starting with checks. 33.Qf7+ Qxf7 (otherwise 34.Qxg7#) 34.gxf7+ Kxf7 (else lose a piece) 35.Rxg7+ Kf8 At this point I saw that 36.Ne6+ wins the exchange but briefly looked at 36.Rdg1 and didn't think it looked right. It leaves more options for black, such as 36...Bxd4. 36.Ne6+ Rxe6 37.Rxd8+ Re8 and now both 38.Rxe8+ and 38.Rdd7 are winning. |

| Feb-12-09 | | DarthStapler: Got it |
|
| Feb-12-09 | | JonathanJ: i found this rather obvious |
|
| Feb-12-09 | | onesax: I see a lot of complaining about the difficulty of these puzzles :S FWIW, I have found each day to be progressively harder, starting with the basic Bxf7 on Monday which was a position I was already well familiar with, up to today's Qf7+. I started out with a brief glimpse of the position and nothing jumped out at me, so I didn't give it any more thought. A couple hours later and again nothing after about 10 seconds, I could see that black had some threats with Rxe5 and maybe Bxd4, so I knew white had to do something constructive, and I saw that Ne6 fell to a back-ranker. Third time I look at the puzzle I decide to actually analyse it properly, and at last result. I first tried to make Bxg7 work (as I had briefly done earlier), but couldn't get anywhere with it. Then I looked deeper at Qf7+ which I had somehow dismissed, and found that the g-file opened up nicely for the rook after the forced sequence 33. Qf7+ Qxf7 (Kh8? 34. Qxg7#) 34. gxf7+ Kxf7 (else drop a whole rook) 35. Rxg7+ Kf8 36. Ne6+ winning. All up about 90 seconds to solve to the end. Which is more effort than I'm usually willing to put into these puzzles TBH, I usually just click through and check the answer if I can't see it in about 15 :) |

| Feb-12-09 | | DavidatHunter: Got it quickly, surprising for a Thursday (I missed Monday's, which I thought was hard for a Monday). Line is totally forced with little choice, so that made the calculations easier. |
|
| Feb-12-09 | | M.Hassan: It is strange! Some medium puzzles, I see the winning move faster than the easy Monday puzzles. In this case, I saw 33...Qxf7+ within 15 seconds and my "gut feeling said that it is the winning move. I also saw: 34.gxf7 Kxf7 35.Rxg7+ Kf8 and did not continue further. Had I made the board, I would have seen the "penultimate" winning move of 36.Ne6+ |
|
| Feb-12-09 | | Justawoodpusher: A Thursday puzzle that I saw within a minute! I agree that this was rather easy. |
|
| Feb-12-09 | | Once: Nice puzzle - a succession of double or even triple attacks, with forced replies in each case. 33. Qf7+ (a check and a mate threat)
33...Qxf7 (forced to avoid mate)
34. gf+ (a check, a pawn fork and a discovered attack on g7) 34...Kxf7 (forced to avoid the loss of the Re8).
35. Rg8+ (a check, a capture and a step towards constructing a mating net). 35...Kf8 (forced - the only legal move).
36. Ne6+ (a check, a knight fork, a deflection of the Re8 and a discovered attack on d7). If black had played on rather than resigning, the sequence would have continued. 36...Rxe6 (forced - the only legal move)
37. Rxd8+ (a check and a capture)
37... Re8 (forced - the only legal move)
38. Rxe8+ (a check and a capture)
38...Kxe8 (forced - the only legal move)
39. Rg6 (threatens both the bishop and pawn)
But now, disappointingly, the forced black replies run out and the sequence ends. |

| Feb-12-09 | | centralfiles: very natural |
|
| Feb-12-09 | | whiteshark: <johnlspouge> Look your favourite avtar is back. :D |
|
| Feb-12-09 | | drnooo: How does bxg7 fail? It is not as fast a win, but what is the bust to it? |
|
| Feb-12-09 | | drnooo: I did not check out the bust to bxg7, but at first glance, after reading the post of somebody saying it fails, could not find the black move to bust it The solution is easy enough the way it is and do not want to spend a lot of energy on the bust to bxg7, but it also looks good enough |
|
| Feb-12-09 | | MiCrooks: A puzzle can be hard simply because of the number of options available. Most people when looking at a puzzle like this would not immediately look at a forced trade of Queens. I think that is what makes this a bit difficult. Once you try it the line falls right out since the rest of the moves make themselves. With the King stalemated on f8 you're going to start looking around for ways to check him one more time and Ne6+ will pop up when you will notice that Rxe6 loses to Rxd8+. |

| Feb-12-09 | | SamAtoms1980: When was the last time you opened the cork on a champagne bottle? This is the same thing. |
|
| Feb-12-09 | | tonythekingfisher: Medium? I got it in 5 seconds!
Really obvious and practically forced from start to finish. |
|
| Feb-12-09 | | AniamL: <fouard> You're right. I made a silly oversight in my analysis, thanks :) |
|
| Feb-12-09 | | WhiteRook48: found 33. Qf7+!! Qxf7 34. gxf7+ Kxf7 but missed 35. Rxg7+!! |
|
| Feb-12-09 | | muralman: Three in a row. This was rather easy. |
|
| Feb-13-09 | | Chicago Chess Man: <newzild> that's exactly the line i favored...... |
|
| Feb-13-09 | | patzer2: For the Thursday, Feb 12, 2009, puzzle solution, White's decoy exchange 33. Qf7+! simplifies to a won exchange-up ending. |
