 | | swr: Nf5+ looks to chase the king away and enable the queening of the e pawn. 42. Nf5+ Kc7
43. d6+
etc
Time to check |

| Aug-25-10 | | LIFE Master AJ: <gofer> Checked my analys with Fritz 12. (I was more right than I was wrong!) :) ;P |
|
| Aug-25-10 | | CHESSTTCAMPS: In this endgame, material is even, but the advanced connected passed pawns and the centralized knight and king provide a winning advantage to white. With the black knight on the edge and too far from the action, creating a third passed pawn would overwhelm the black king. Therefore, 42.Nf5+ finishes efficiently by controlling e7, facilitating the promotion of the e-pawn. A) 42... gxf5 43.g6 Ke7 44.g7 and the g-pawn promotes. B) 42... Kc7 43.d6+ Kd8 44.e7+ Kd7 45.Ng7 wins.
Considering the lack of alternative logical continuations, I doubt that any kibitzer will come up with anything else. After yesterday's drama, this is pretty mundane and technical. |

| Aug-25-10 | | CHESSTTCAMPS: <LIFE Master AJ: What was yesterday's puzzle ... I missed it. >
A very interesting spoiler - Sunday level in complexity and likely based on an error in the game score. You might want to check the Tactics Archive and skim through 6 pages of kibitzing. |

| Aug-25-10 | | Abu Dina: First ever post!
Sorry if this has been repeated a trillion time s but here is my 2 cents:
Lovely move by white. Black is doomed.
gxf5 and white g6 etc...
Kc5 and pawn on e6 is home and dry.
Nd4 and Black's King is pegged back.
How do these guys do it?! |
|
| Aug-25-10 | | AndreMorais: Took me about 2 seconds to solve this one: just a glance at the diagram. Found it easier then yesterday´s. |

 | | David2009: K Lie vs Bu Xiangzhi, 2008 White 42? Easier than yesterday! 42 Nf5+ gxf5 (if Kc7 d6+ etc) 43 g6. If 43...Ke7 d6+.
The Black N can check in three moves, just too late:
43 ...Nb5 44 g7 Nc7 45 g8=Q Nxf5+ 46 Kf3 1-0 but not 46 Kxf5??? Ne7+ saves the day. Time to check the
game:

As expected. The pre-puzzle moves are interesting. Rewind to move 40:

Setting this up on Crafty End Game Trainer, Crafty defends against 40 Kf4 with 40...Kd6 41.g5 h5 exactly as in the game, and loses to 42.Nf5+.
Crafty link: http://www.chessvideos.tv/endgame-t... Rewind to move 39 and Crafty finds a decisive improvement in Black's defence:

After 39 Nd4 Black plays NOT 39 Ke7? but 39 a6!. If 40 d6 Black plays 40... Nc2+! 41.Nxc2 Kxe6
drawing comfortably: indeed, if White overpresses he loses. Crafty link: http://www.chessvideos.tv/endgame-t... |

 | | Patriot: This did seem easy, but I was very cautious not to fall for a spoiler like yesterday. 42.Nf5+
A) 42...gxf5 43.g6
A1) 43...Ke7 44.g7 
A2) 43...h4 44.g7
B) 42...Kc7 43.d6+ Kd8 44.Ng7
C) 42...Kc5 43.e7
<Abu Dina> Welcome aboard! |
|
Aug-25-10
| | Patriot: I forgot to include the obvious line:
D) 42...Kxd5 43.e7 |
|
| Aug-25-10 | | desiobu: Sacrifices like 42. Nf5+ seem to be common in knight endings because the king and knight are so slow. |
|
| Aug-25-10 | | Brandon plays: Took me a couple of minutes to think about Nf5+. I think that works. I didn't really analyze it out all the way, but black's knight is so far away and there is no way that black can stop at least one of those pawns from promoting. |
|
| Aug-25-10 | | jimmyjimmy: I didn't notice that if black captured the knight, it would allow white to promote his pawn. Black has no choice but to resign. I missed this one. |
|

| | benveniste: 41. g5! makes this all possible, and to my eye was a harder move to find. |
|
Aug-25-10
 | | Once: <Abu Dina>: welcome! And good to start your chessgames.com career with a win. |
|
| Aug-25-10 | | Abu Dina: I think Nd4 made it possible.
White had to play g5. otherwise whites king comes under check with blacks own g5. White knew his king had to stay there. anything else and the knight and pawn on the d file are black's fodder. |
|
| Aug-25-10 | | Abu Dina: Once, thank you for welcoming me!
Last night was also my first night joining a local chess club. I thoroughly enjoyed it! Can't wait till next Tuesday even though I got battered twice by the club captain! :( |

| | Once: <Abu Dina> I think you will find that chess doesn't so much have a learning curves as a series of learning steps. Most folk find that they can get stuck at one level for a while, then go up in one big jump. The difficulty seems to be in finding the stick-at-ability to hang on in there when it all seems much too hard. Many folks learn the moves, then give up the game when they get beaten easily by a slightly more experienced player. So I wouldn't worry too much about losing to the club captain. If you can keep on playing, and learning, and <most of all> enjoying the game, it won't be long before it starts to get a whole lot easier. Have fun :-) |

<42.?>
Target: 2:10;000
Taken: 1:37;897
Material: =
Candidates: Nb5†, <[Nf5†]> -ML-
The Black is way out of the game, it either suggests trapping it, or sacrificing our own to let the pawns do the works. The latter is the case here. White wins after: <42.Nf5†!> the obvious move is the capture but this makes the followup rather straightforward for White. /A\
<42....gxf5 43.g6 > the Black King cannot reach the g-file due to the e6 pawn, the h-pawn is too late and the Knight even more; promotion is unstoppable. So the Black King has to move. Up the board however is not recommended seeing the pawn going up. /B\
<42....Kc5/Kxd5 43.e7 > is quick enough. The last alternative however, will win White too much tempi. /C\
<42....Kc7 43.d6† Kd8 44.e7† Kd7 45.Ng7 > and it is game over with e8=Q incoming. Time to check. |

 | | YouRang: Pretty obvious that today was about finding a promotion tactic, which made 42.Nf5+ fairly easy to spot. Capturing the knight springs our g-pawn to run, while moving the king out of check springs the central pawns. Nice puzzle. |
|
Aug-25-10
 | | kevin86: The knight pawn needs to be sprung to advance and the knight sac at f5 is the springer-(pun intended). Easier by far than yesterday-oh,by the way the "decoy" solution turned out to be correct,as black in fact resigned. A positive side of unintended consequences---or double blindness. |
|
Aug-25-10
 | | M.Hassan: 42.Nf5 is the winner
42......Kxd5 or Kc7 or gxf5
White can promote a pawn |
|
| Aug-25-10 | | ZUGZWANG67: Knight endgame where material is even. Black has a protected passed pawn and White 2 connected passers. The main difference between W & B lies in the position of the Knights: W's one is very active while the black one is practically off the board. 42.Nf5+ and:
a) 42...gxf5 43.g6 Ke7 44.g7 and 45.g8Q.
b) 42...Kc7!? 43.d6+;
b1) 43...Kc8 44.e7 Kd7 45.Ng7;
b2) 43...Kd8 44.e7+ Ke8(d7) 45.Ng7(+)
I think this is it.
Time to check.

Ok. At least one resolved. After yesterday's debandade and after having missed h5 sunday I needed this one. :0) |

And I would add to <Once>'s excellent advises that it would be a great idea to play often <and> solving whenever you have time. ChessGames provides us with a huge advantage: that of being able to analyse and exchange with others chess enthousiasts. But I think it's not enough. One needs to solve often. Here are 2 strong tools to help you doing so. One features 10000(!) puzzles from GM games. Some of them are challenging. The second one provides more trivial exercices adapted to your rating (the site provides it's own ratings) and the possibily to fight the clock. This site has more than 23000(!!) puzzles. http://www.wtharvey.com/index.html

I hope this will help you in your improving process.
Peace! |

| Aug-25-10 | | Justawoodpusher: For me endgame puzzles are comparably more easy to solve then a middle game puzzle of the same day of the week. This one was no exception. Do others have the same feeling? |
