| Dec-02-08 | | zooter: very interesting puzzle today
64...Nf3+ should win for black
a) 65.Kg2 Qg1+ 66.Kxf3 Qh1+ skewers the hanging white queen b) 65.Kf2 Qg1+ 66.Ke2 (66.Kxf3 leads to a) above) Qe1+ (where are you running? Take the knight!) Time to check when white resigned. The idea is that the white queen is hanging and a check on the h1-a8 diagonal is killing |
|
| Dec-02-08 | | Infohunter: By means of a discovered check, Black walks White into a skewer of his Queen. Not too hard, but enjoyable just the same. |

 | | cu8sfan: I found today's puzzle quite difficult. Maybe it's because I was looking for an immediate kill. |

| Dec-02-08 | | johnlspouge: Tuesday (Easy):
N Battulga vs F Farid, 2008 (64…?) Black to play and win.
Material: N for B+P. The White Kf1 has 2 legal moves, both dark squares, either of which Ne1 can control after a single move. The Black Qd1 is on the same rank as Kf1, obscured only by Ne1, so Black has a powerful discovered check. The White Qc6 is loose. The Black Kf7 is insecure, so counterattack is the best defense. Candidates (64…): Nf3+
64…Nf3+ 65.Kf2 [Kg2 Qg1+ 66.Kxf3]
65…Qe1+ 66.Kxf3 [Kg2 66.Qg1+ 67.Kxf3]
66…Qh1+
All roads have led to Rome.

| Dec-02-08 | | dzechiel: Black to move (64...?). White is a pawn up. "Easy." Once you notice that the position of the white queen is on the long diagonal, you start looking for combinations that look like: 64...Nf3+ 65 Kf2 Qe1+ 66 Kg2 Qg1+ 67 Kxf3 Qh1+
and black picks up the white queen. |
|
| Dec-02-08 | | arsen387: I went for a mate here and missed the solution. Tried 64...Nd3+ 65.Kg2 Qe2+ 66.Kg3 Qf2# and tried to find mate in other lines too but unfortunately there's no mate after 66.Kh1 :) |
|
| Dec-02-08 | | karoaper: Wow, this was impossible for me. Problem was that I didn't have enough position understanding to see that mate was not possible for black, even though the black queen and knight had the signs of a deadly attack going. This is the thing with chess, a position like his, but for a change in one piece, would be mate for white. Here, however, I spent good 5 minutes just moving the pieces about hoping for the clincher, which didn't come. |

| Dec-02-08 | | Gilmoy: My process:
0. Black has an obvious discovered check. Look for a mating net. Feels insufficient, tho -- in particular, the h3-pawn denies our Qg4+. 1. Examine (that means you briefly glance at) the smites: <64..N+ 65.Kf2/Kg2> forced. Noob idea: Let the N take away one of those squares: <64..Nd3+ 65.Kg2> 2. Smite again: <65..Nf4+ 66.Kf2/g3/h2>. (Note: You go through this very quickly. Don't worry about being thorough -- your goal is just to highlight some nuggets to constrain your further searches, so that your later board-staring phase is not entirely clueless.) 3. <66..Q+ 67.Kf3/xf4/h4/...>. Gee, <67.Kf3 Qh1+> would be a hoot ... 4. Ding! That works! The pretty way to <force Kf3> is to put your N there, and use it to support adjacent Q checks. Backtrack: <64..Nf3+> and White can't decline the poisoned N forever. If your pattern recognition is advanced enough, you could skip 1-3 and jump directly to 4. The rest of us patzers can still plug in and grind. When in doubt, smite his armor and see where it creaks. |

| Dec-02-08 | | JG27Pyth: Wow. I wish I had my thinking together all the time like I did with this one. I quickly spotted the skewer possibility with the Queen far from the King on the long diagonal. I then visualized a mating possibility... if I could drive his K to f3 and support my queen to give check from f2, it's mate. That didn't seem practical, but Kf3 was also where I wanted his K for the skewer, with my Queen able to give check from h1. Sure seemed like it was time to see if I could drive the K to f3. 64.♘f3+ ♔f2 65.♕e1+ ♔g2 66.♕g1+ ♔xf3 bingo
Very satisfying to solve with what felt like something approaching a logical process. |

 | | chrisowen: The idea of picking up the queen was a tad more difficut then a normal tuesday puzzle as it required sacking the poisoned knight. Looks like 64..Nf3+ Kf2 Qe1+ Kg2 Qg1+ Kxf3 Qh1+ should do it for now. |
|
| Dec-02-08 | | goldfarbdj: Nd3 was the instinctive move for me, but it seemed like there were many more variations than there "ought" to be for a Tuesday puzzle. Then I spotted the skewer possibility and all became clear. |
|
| Dec-02-08 | | agb2002: Black can take advantage of the fact that the white queen is not protected with 64... Nf3+: A) 65.Kg2 Qg1+ 66.Kxf3 Qh1+
B) 65.Kf2 Qg1+ 66.Ke2 Qe1+ 67.Kxf3 Qh1+
I’ve tried unsuccessfully to find a forced mate so I’ll stay with 64... Nf3+. |

 | | offramp: The opening is the infamous Stoke-Adams Attack. |
|
| Dec-02-08 | | agb2002: I think that the line in the game 65.Kf2 Qe1+ is technically better than my B) line because it does not require that d3 is unavailable for the white king. Economy is important... |
|
| Dec-02-08 | | Shams: can someone pleeeease explain 17...Rh7 to me? |
|
| Dec-02-08 | | zooter: <agb2002: I think that the line in the game 65.Kf2 Qe1+ is technically better than my B) line because it does not require that d3 is unavailable for the white king. Economy is important...> I had the same line as your B and don't find it any bad...the pawn on c4 does the job quite well...and both lines end at move 67... |
|
| Dec-02-08 | | newzild: I'm embarrassed to say this, but today was the first time I've missed a Tuesday. I looked at the position for at least four minutes and just couldn't see it. Usually I look first to see what pieces are unprotected (ie: the white queen), but today I didn't and paid the price. Lesson learned, I guess. |
|
| Dec-02-08 | | kirchhoff: Like many others, I spent a few minutes looking for a mate, realized that there wasn't one, and then saw the correct move. Nice puzzle. |
|
| Dec-02-08 | | euripides: Lots of imaginative play on both sides throughout this game. |
|
| Dec-02-08 | | whiteshark: 64...Nf3+ to win the unprotected ♕c6 subsequently. |
|
| Dec-02-08 | | agb2002: <zooter: I had the same line as your B and don't find it any bad...the pawn on c4 does the job quite well...and both lines end at move 67...> It is not bad, of course, but the game line is preferable because is simpler. |
|
| Dec-02-08 | | jahhaj: <Shams: can someone pleeeease explain 17...Rh7 to me?> Black wanted to play g5 but needs to protect f7 (otherwise fxg5 followed by Qxf7). Rh7 is obviously one way of doing that. After the more 'obvious' Rf8 I guess black was worried about something like 17...Rf8 18.Nd4 g5 19.fxg5 hxg5 20.h4 when gxh4 allows Bh6 and Qxf7 will follow soon. Just my quick view. Haven't really analyzed anything so might not be correct. |
|
| Dec-02-08 | | Civhai: First, I tried to play for a mate and began with Nd3, because this is the only possibility to get the f2 square and if the king goes there, it would be difficult to mate him. After not having found a mate after one minute, I thought about winning that queen. If I could get the king to f3, that would be nice. First thought was Nf3, wich worked straight away after (Kf2 Qe1) (Kg2 Qg1) Kxf3 Qh8+. |
|
| Dec-02-08 | | zb2cr: Nothing to add to what <zooter>, <dzechiel>, <johnlspouge>, <Gilmoy> and others have written. |
|
| Dec-02-08 | | goodevans: Thought just for a millisecond I'd got it wrong, but 65 ... Qe1+ and 65 ... Qg1+ amount to the same thing. A quick scan through the other postings shows a slight leaning towards the move played, but there's not much in it. |
